Providing resources and ideas for therapies and medical developments for Parkinson's disease:
Mercury is toxic to the human body and specifically to motor neurons which when inflamed, disabled or killed off by mercury, is a possible causative factor for Parkinson's disease. Mercury and many other heavy metals (lead, chromium, ...) are bio-accumulative, meaning that they make their way into the body but the body can not easily dispose of it, thus accumulating over time. The primary human target areas susceptible to mercury are the brain and nervous system, the kidneys, and the cardiovascular system. Mercury sources, measurement and detoxification by chelation therapy are all discussed.Mercury can enter the body in three forms:
The most common toxic form is Methyl-mercury which is readily absorbed into the body through the gastrointestinal tract and has entered the aquatic food chain thanks to the output from coal burning plants making its way into the oceans. Mercury has been shown to be a neurotoxin and to cause a large influx of calcium ions into the neuron cell thus inhibiting dopaminergic neurotransmission and causes the physiological characteristics of Parkinson's disease (tremors, insomnia, muscle atrophy, muscle twitching, memory loss and degraded cognitive function) and even to neuron cell death.Sources of mercury include:
The link between mercury and ill health including Parkinson's traits is clear and established.
How Mercury Causes Brain Neuron Damage - University of Calgary
Amalgam dental fillings are composed of about 55% elemental mercury, 44% silver and 1% of trace metals like zinc, copper and tin, which together bond and form a solid metal material used to repair dental cavities. The United States Food and Drug Administration (FDA) still views the use of mercury amalgam fillings as safe and the American Dental Association (ADA) still regard mercury amalgam fillings as safe but research has shown otherwise. The Environmental Protection Agency (EPA) declared in 1988 that scrap dental amalgam material was a hazardous waste and OSHA has mandates on how to handle amalgam fillings. The act of chewing and brushing release mercury from dental fillings. Acids found in foods and drinks (especially if they are hot) can cause the release of mercury from the amalgam. It's not surprising that in 2008, Norway, Sweden and Denmark banned the use of mercury in dental fillings.
Typically the silver-mercury dental materials are shipped to dentists with the quantities in pre-measured containers ("precapsulated") so the quantity is "fool-proof" but the material quality and the mixing of the materials to form the amalgam is not and if not mixed completely with all mercury reacted with the silver, the amalgam will have the propensity to release the unbound mercury. This phenomena is more likely to occur at the greatest levels in the weeks following a dental restoration. Note that some dentists (typically not USA) may employ reusable capsules and may error on the ratio of the mix (a process referred to as trituration). This practice is old, subjected to exposure and oxidation, generally more error prone and time consuming and should be avoided. The mixing machines ("amalgamators") should oscillate at an optimum frequency, amplitude and duration for a given capsule length and size and at the optimum temperature, in order to form the best dental amalgam. Over-mixing creates an amalgam which is hard to form and porous and prone to fracture while under-mixing may create an amalgam which is too soft with too much free mercury. Dentists who manually mix amalgam will be prone to have an even greater risk of error.
In order to mitigate any problems with the release of mercury from amalgam dental filings, the fillings can be removed and replaced with composite or ceramic material. The tooth can also be given a crown or a root canal performed to replace the tooth with a prosthetic. Amalgam replacement must be done wisely as it has the potential to generate mercury vapor and fine particles which can be ingested, resulting is an even higher dose of mercury poisoning. Amalgam removal should not be performed on those are or about to be pregnant. It is essential to have a mercury safe dentist who follows specific safety protocols when removing the fillings.
Mercury: The poison in your teeth: Amalgam stimulated with a tooth brush (Dr. Tom McGuire DDS)
Research has shown the relation of exposure to dental amalgams and the toxic burden of mercury in the human brain and kidneys.References:
The International Academy of Oral Medicine and Toxicology (IAOMT) has developed the Safe Mercury Amalgam Removal Technique (SMART) protocol recommendations. The IAOMT website also has a searchable worldwide dentist database or check out Dr. McGuire's database for a dentist with skills to meet the IAOMT protocol for removing amalgam fillings.Safe protocols for amalgam removal include:
IAOMT Safe Mercury Amalgam Removal Technique (SMART) protocol. Ignore the comment about taking chlorella (1 min and 3:53 min into the video) as it is not a good chelator (pronounced KEY-lay-tor) and will move rather than remove mercury.
Amalgam fillings can be replaced with porcelain inlays or onlays bonded to the tooth or with a composite.
Be sure to use one of the newer bonding agents which do not contain Bisphenol A (BPA) which is a bio-accumulative, xenoestrogen endocrine disrupting chemical which has estrogen hormone like properties.
This is also true in choosing composite filling materials.
Choose materials which are BPA-free.
Also be sure to reduce your BPA exposure by choosing glass over canned food products and don't microwave polycarbonate plastic (marked with a number 7 recycling code) food containers.

The goal of removing mercury amalgam dental fillings is to remove a source of mercury which will constantly release low doses into your body. Another reason is that it is a prerequisite for a mercury detoxification process known as chelation therapy which is used to remove mercury from one's brain and body tissue. It is a requirement to remove amalgam fillings prior to chelation as chelation will pull mercury from amalgam fillings creating a toxic event.
According to the ACC mercury detox protocol, any remaining bit of amalgam remaining in the tooth near the tooth root might induce the need for a root canal as chelation agents will be drawn up through the root of the tooth in an attempt to bind with the mercury. A grey stain remaining on the inside of a filling is more likely to be silver oxide and not mercury. A visible white spot revealed on an x-ray is problematic and an indication that a speck of mercury amalgam is remaining in the tooth.
Binders such as activated charcoal can be taken 20 to 30 minutes before the amalgam removal procedure starts for the purpose of attaching to any mercury particles that may be ingested. For more on binders, see below.

Research has shown a significant reduction in the level of mercury found in blood plasma after amalgam removal.
Mercury accumulates in body tissue and organs and generally can not be removed mechanically. Be very skeptical of those offering a vitamin cleanse to remove mercury as there is no evidence that it will be effective. The act of using a mercury binding molecule to attach itself and engulf mercury atoms in a way that it is viewed by the body as organic waste that can be expelled by the body's regular organs, the liver (including bile and GI tract) and kidneys, is known as a chelation therapy. The goal of the chelator is to bind to the toxic metal to make it non-toxic, water soluble and easily excretable by the body. Mercury is known to to have a very high affinity to sulfhydryl (SH) groups. This affinity is exploited to attach to mercury and remove it.
The chelating agents possess a ligand (molecule that binds to a central metal atom by donation of one or more of its' electron pairs) that forms a bond with the metal to be removed. The chelating agent forms a stable complex with the toxic metal to shield human tissue from the metal ion, thereby reducing the local toxicity. The resulting molecule can then be mobilized and excreted in urine or feces.
Warning: While the chemistry of chelation is well known, there are not a lot of studies showing efficacy and many can do more harm than good if they mobilize rather than remove mercury or inflame the brain due to removing mercury from brain tissue. This website does not endorse chelation or any particular chelation therapy due to the dangers and extreme risks involved. Chelation is neither a reliable or safe therapy and is not recommended.
|Chelation Agent||FDA Approved||Description||Toxicity (LD50) mmol/kg (lower=more toxic)|
|DMSA||yes||Dimercapto Succinic Acid (DMSA) C4H6O4S2 is considered safer and less toxic than DMPS. Goes by the trade name "Chemet" but also called "Succimer". DMSA does not enters the cells but relies on glutathione or other mercury mobilizer to push toxins out where DMSA is waiting to bind to them. DMSA is typically given for 3 days followed by 11 "off" days. The body needs the "off" days to remake glutathione. The dosage is based on body weight. Chelates lead and mercury (favors organic ethyl-mercury). DMSA targets extracellular (outside the cell) mercury, the mercury found outside the cell walls in body tissue. DMSA does not have the ability to pass through cell membranes and must team up with glutathione or ALA to grab intracellular (inside the cell) mercury. Digestible and does not result in a significant loss of essential metals like zinc, iron, calcium and magnesium. Concurrent use with EDTA is not recommended. Excretion pathway: kidneys (thus drink a lot of water to flush the resulting DMSA-Mercury compound). Half life: 4 hrs.||13.58|
|DMPS||no||2,3-Dimercapto-1-Propane Sulfonic Acid (DMPS) is used when all other detoxification methods have been exhausted. Goes by the trade name "Dimaval". Fast acting. May be over effective on first use. Not to be used when dental amalgam fillings are still resident as saliva delivery of the chelating agent will bind to the mercury and can result in acute mercury poisoning. DMPS favors inorganic mercury. DMPS targets "extracellular" mercury, the mercury found outside the cell walls in body tissue. Avoid DMPS "challenge tests" as it creates a toxic mercury load. DMPS is legal in Germany but not FDA approved for the USA. Also a strong chelator of copper. Excretion pathway: kidneys (thus drink a lot of water to flush the resulting DMPS-Mercury compound). Half life: 8 hrs||5.22|
|EDTA||yes||Ethylene Diamine Tetra-Acetic acid (EDTA) amino acid was used in the National Institute of Health (NIH) TACT trial.
Considered safe by the FDA although it can be toxic to the kidneys.
Kidney function should be monitored. Has the added benefit of clearing plaques in blood vessels.
Does not form as strong a bond with mercry as a di-thiol chelator.
EDTA was first used in the 1950's as a treatment for heavy metal (lead, mercury, copper, iron, calcium, chromium, cobalt, cadmium, magnesium, vanadium, zinc, ...) poisoning.
Best used for detoxification treatment of cadmium and lead. Avoid "challenge tests" as it creates a toxic load.
According to Dr. Andy Cutler PhD, it can form a dangerous compound when it binds with mercury (hgEDTA) which is even more difficult to remove.
There are two versions, NaCaEDTA (calcium EDTA) and NaEDTA (disodium EDTA) of which NaEDTA easily binds with calcium and can cause hypocalcemia induced cardiac arrest and thus should not be used on children. Calcium EDTA, which is approved to treat lead toxicity can be given as a short IV push, but disodium EDTA, which may be used as a potential treatment for vascular disease, must always be given by a slow intravenous drip, at a rate no more than 1 gram per hour, otherwise, the calcium blood level drops dangerously fast. Typically administered intravenously and not intramuscular. Available as liposomal oral EDTA:
|ALA||no||Alpha Lipoic Acid (ALA) C8H14O2S2 is the only one of the common chelator agents which crosses the blood-brain-barrier and is used after chelation with other agents or in combination with other chelation agents.
ALA targets "intracellular" mercury, the mercury found inside the cell walls on both sides of the blood-brain-barrier (BBB).
Must wait three months after amalgam removal before starting chelation with ALA.
Excretion pathway: liver.
Half life: 3 hrs
|Glutathione||Glutathione (GSH) is available as a neuro-protective supplement which is hard for the body to absorb and thus is more effective if given intravenously but is still ineffective due to a short half life of less than 20 minutes (ref).
It has been found to be far more effective to let the body produce GSH by consumption of its precursors: N-AcetylCysteine (NAC) Glycine and Glutamate.
Glutathione is also supported by a diet of sulfur-rich foods: garlic, ginger, onions, eggs, and broccoli sprouts.
Glutathione is typically generated by cells in the body as a natural detoxifying agent.
Mercury has an adverse effect on Red Blood Cell (RBC) glutathione making it more difficult for a mercury toxic body to excrete mercury.
Glutathione is often not considered a true chelation agent because it does not contain two or more binding groups (dithiol groups), it has one.
ACC protocol considers Glutathione IV a dangerous option as it will redistribute mercury causing more damage rather than remove the mercury from the body.
Supplementing the precursors to glutathione, allowing the body to generate glutathione is preferred.
Glutathione has the ability to work intracellularly (inside the cell membrane) and can pass mercury to extracellular (outside the cell) chelators such as DMSA and DMPS.
Typically two glutathione molecules are required to bind and chelate a single mercury atom.
Glutathione excretion pathway: liver.
|Dimercaprol||yes||Dimercaprol (also called British Anti-Lewisite or BAL) is used to tread lead, mercury, bismuth, silver, nickel and arsenic poisoning. High doses can cause coma and seizures. Not to be used to chelate iron or cadmium because the resulting complex is toxic.||1.1|
|DPA||yes||Penicillamine (DPA) sometimes used to treat bismuth, copper, lead, mercury, and nickel toxicity. Primary adverse effect is an allergic reaction in people who are also allergic to penicillin. Tends to redistribute mercury with adverse reactions. |
Also see: The enigma of parkinsonism in chronic borderline mercury intoxication, resolved by challenge with penicillamine
The d-penicillamine (dimethyl cysteine or (2S)-2-amino-3-methyl-3-sulfanylbutanoic acid) variant, also known as Cuprimine, is an oral chelator which is less toxic and preferred over the l-penicillamine variant.
|DFO||yes||Deferoxamine (DFO) mesylate is a chelator used to treat iron and aluminum (AL) toxicity. Primarily used for AL-related diseases in renal patients.|
|MiADMSA||no||Monoisoamyl DMSA was synthesized by generating an ester of DMSA which is more lipophilic (better able to disolve in fats) when compared to DMSA making it more capable of mobilizing intracellularly bound toxic metals.
Found to be more effective at chelation of arsenic and lead without redistribution when combined with DMSA.
|Emeramide (NBMI, Irminix, OSR, BDTH2)||in trials NCT02486289|
N1,N3-bis-(2-mercaptoethyl) isophthalamide (NBMI) (chemical name) also known as Irminix (drug name), Emeramide (INN generic drug name) or OSR (oxidative stress relief when marketed as a dietary supplement) is a new chelator and antioxidant which is hydrophobic and can pass through the blood-brain-barrier and chelate mercury from cell organelles like mitochondria. Emeramide/NBMI was developed by the biotech firm EmeraMed, passed FDA phase 1 and 2a human trials and was available for "compassionate use". NBMI is a di-thiol chelator which forms a strong bond with mercury (will not drop and mobilize mercury - known as the kinetic property of the chelator) and is excreted through the bowel in the stool.
Once NBMI binds to mercury, the mercury becomes non-toxic and is excreted through the cytochrome P-450 (cytochrome: enzyme family, P: protein, 450: max wavelength of absorption in nano meters when enzyme is bound to CO) system pathway (a heterogeneous group of about 50 enzymes that catalyzes various oxidative reactions in the liver, intestine, kidney, lung, and central nervous system to support detoxification). Note that some foods and supplements can inhibit the CY P-450 pathway (Mechanism of CYP2C9 Inhibition by Flavones and Flavonols). Excretion is a slow process taking about 30 days to complete. NBMI can also bind to a lesser extent with Arsenic, Lead and Cadmium and not with essential minerals like Calcium, Magnesium or Zinc. The manufacturer claims that Emeramide/NBMI is non-toxic and does not deplete essential minerals. It also discriminates bound metals so that it does not deplete essential iron and copper bound to proteins but will chelate free iron (Fe2+) and free copper (Cu2+). Note that free iron along with hydroxyl (OH) and other free radical species, has been implicated in the pathogenesis of Parkinson's disease.
NBMI raises glutathione (GSH) levels by reducing the body's consumption of glutathione used to address toxic heavy metals (ref). NBMI is also a powerful antioxidant with an ORAC value of 192,400 (by comparison Acai fruit has an ORAC value of 18,500). Note: people with suspected yeast or Candida problems, or anyone who is on antifungal medications, should not take Emeramide/NBMI until their yeast conditions were under control. EmeraMed is developing Emeramide with PCI Pharma Services to provide a quality pharmaceutical grade and purity, supply. NBMI is also available as an industrial chemical which is NOT suitable for human consumption. Shelf life: 5+ yrs. Excretion pathway: liver. Half life: 18 - 22 hrsVideos:

Chelation therapy must be avoided prior, during and immediately after dental mercury amalgam replacement (note: the developers of NBMI claim to be free of this problem). Do not consider chelation prior to dental amalgam removal as the chelation agent may be delivered by one's saliva to the mouth and dissolve the mercury in the amalgam resulting in acute mercury poisoning. Also note that dental amalgam replacement may temporarily elevate mercury in the body. Thus it is considered unwise to undergo chelation for four days to a week after amalgam replacement when using DMSA or DMPS or for three months after amalgam replacement when using ALA. One should find an IAOMT SMART certified dentist who has the safety gear to keep both the patient and dentist safe from mercury vapors generated during the amalgam removal process.
All effective chelation protocols will call for the replacement of beneficial vitamins and minerals, which are also removed by the chelation agents.
The removal of mercury amalgam dental fillings with modern methods is a no-brainer as they can be safely removed without exposing the patient to harm. Chelation on the other hand does not have a clear and defined exit path for the mercury being removed and thus can impose harm on a patient, depending on the chelator. The mercury being removed from the body by chelation is often buried deep within tissues spread out among organs, fat and brain matter and the journey it takes to exit the body often includes being relocated after being dropped by the chelator compound and traveling through healthy tissue causing new mercury toxicity damage. Developers of NBMI claim that NBMI is a superior chelator because it does not drop mercury once bonded. Chelation requires balancing the type and dosage of the chelator so that the removal rate is tolerable, the toxicity of "droped" mercury is not inflammatory or hazardous, the burden on the kidney or liver excretion path is not doing organ damage and the accidental chelation of essential nutritional minerals is not detrimental. Chelation can present many hazards and requires recovery breaks for the body to heal. If chelation is causing pain, severe anxieties or depression, brain fog, head aches or discomfort, stop chelating as the dosage is too high! Chelation does not benefit the patient who is tough or is content with suffering as it may be doing damage. Go slow with light tolerable doses. If the patient body burden of mercury is high, start light and be safe. The discussion of chelation therapies below is not an endorsement of chelation, any specific chelation agent or of any one chelation protocol. When one begins chelation therapy, they are starting at the highest level of mercury burden in the body and thus should start with the lowest dosage of chelator and stay at a low dosage for many rounds. The dangers of chelation are discussed in detail below.
The dithiol (two thiol organosulfur compounds of S-H, Sulfer-Hydrogen) group of chelators (DMSA, DMPS, ALA, NBMI, etc) work as chelation agents because they have two sulfur atoms available to bind with mercury (and drop a bond eg to Hydrogen), to form two bonds with the mercury atom. Note that the sulfer-mercury bond is strongest in a 180 degree bond and thus geometries which includes multiple molecules in a 2:2 ratio of chelator to mercury atoms is found to be more prevalent. Once the bonds with the mercury atom have been made, the mercury should no longer cause harm to the body and will expose an organic shell which the body can expel. In reality, mercury is often droped and relocated causing new harm in new tissue.
DMSA: is a dithiol chelator which bonds to mercury and exits the body mostly via the kidneys and urine with small amounts (<1%) excreted by the liver, GI tract and feces. DMSA can not cross the blood-brain barrier but can rid the body of mercury and lower blood level concentrations of mercury. The resulting DMSA-Mercury compound is excreted by the kindneys as urine, thus DMSA chelation must be accompanied with drinking a lot of water in order to purge mercury. The result of not consuming enough water will be to retain mercury and to allow it the opportunity to be redistributed.
Ratio DMSA:Hg shown is 1:1. Other ratios are common (eg 2:2) with geometries supporting two 180 degree bonds with two mercury atoms.
For a study of DMSA configurations see Mercury binding to the chelation therapy agents DMSA and DMPS and the rational design of custom chelators for mercury (PDF) (2004)
ALA: Similarly Alpha Lipoic Acid (ALA) has two sulfur atoms which can bind to mercury.
ALA can cross the blood-brain barrier to draw mercury from the brain (ref).
Preparation is required so that the natural flow will be from brain (area of high concentration) to the body (where the body concentration of mercury was lowered prior by chelation with DMSA).
It is essential that this concentration gradient be established prior to using ALA as ALA is capable of moving mercury in and out of the brain.
Chelation of mercury (Hg) using Alpha Lipoic Acid (ALA) C8H14O2S2
ALA chelated mercury is typically excreted by liver in bile.
Ratio ALA:Hg is 2:2
NBMI: as a dithiol chelator it has two sulfur atoms which can bind to mercury with the distinct advantage that the spacing of its sulfur atoms is not fixed and thus can easily accommodate two bonds with a mercury atom with one NBMI molecule unlike ALA which requires two molecules to bind to two atoms of mercury.
NBMI attaches to mercury to immediately render it non-toxic and requires a temperature of 230 degrees Celsius to break the bond.
NBMI is also a strong anti-oxidant and scavenger of free radicals.
It is lipophilic (fat soluble) and can cross the Blood-Brain-Barrier (BBB), cell membranes and enter cell organelles where metal toxicity is most damaging.
Ratio NBMI:Hg is 1:1
Animation of NBMI binding to mercury
Many medical practitioners will want to perform a "challenge test", also known as a "provocation test" or "mobilization test", as a way to measure the level of mercury in the body and monitor chelation progress. Blood tests are transitory and only measure mercury at a given moment in time. This is also true for urine tests. A hair test will measure mercury over a longer but still short period of time. These tests ignore the reality that mercury is not typically mobile and has taken up residence in organs or fat in the body. The challenge test uses a fixed but large dosage of a chelator to dislodge mercury from the body for measurement with a blood, hair or urine test.
Each chelation agent may preferentially bind to a given metal first, thus hiding the presence of other metals. Mercury can also be tightly bound to body tissue and thus may not be removed until significant amounts of other "preferred" toxic metals have been removed first.
The ACC chelation protocol recommends against this practice as it does not follow their protocol of multiple doses spaced at the half life of the chelation agent so that mercury if dislodged from a chelator, can be picked up by the next round. The American College of Medical Toxicology (ACMT) published a position statement also recommending against the use of this test (ref) as not "accurate or reliable" and is "of no benefit to patient outcome, may actually prove harmful".
The ER guide "Goldfrank's Toxicologies Emergencies" notes that the "provocation test" "tends to increase urinary elimination of mercury, regardless of exposure history and baseline excretion" and states that it is of "dubious value".
Symptoms of mercury toxicity can occur at any blood or urine level. Blood and urine mercury levels reflect recent exposure and do not correlate with total body burden and usually under reflect tissue levels and even more so, CNS levels.Also see:
Measuring one's level of mercury toxicity is difficult as where the mercury ends up, determines its harm to one's body.
It is also hard to quantify the level of mercury in one's body.
Mercury is bioaccumulative which means that it gets absorbed by body tissue and little is excreated.
Blood tests can accurately measure the level of mercury in the blood, but the measurement has no relevance to the amount of mercury already absorbed by body tissue nor can it predict how much of the mercury in the blood will be expelled or absorbed.
It will merely be a measurement of mercury in the bloodstream and can be a point-in-time indicator of the health of one's current diet or environment.
Blood test limits are usually acceptable if less than 10 micro-grams/Liter.
A low measurement of mercury in the blood is often mistaken for a low body burden of mercury.
This is also true for urine and feces tests as they have the same limitations as blood tests.
Hair tests do have the advantage of a measurement over a greater duration of time but otherwise have the same limitations.
Hair, urine and feces tests can also be misleading because those that fail to excrete mercury efficiently tend to show low measurements but are more mercury toxic and tend to have a higher body burden of mercury (see video of Dr. Boyd Haley on the topic of hair tests and mercury retention).
One can get tested for mercury levels in the blood, hair, urine and feces as well as in body tissue.
List of testing companies
OligoScan: The OligoScan is a toxic metals scan which unlike the blood test can actually measure the mercury burden in tissue which makes the measurement much more relevant.
It uses light spectroscopy (spectrophotometry) to measure the levels directly in the tissue being scanned (typically the hand).
It is based on the scientific principle that every chemical element absorbs, emits or reflects light (electromagnetic radiation) of a given wavelength.
The more the tissue is concentrated with a given element, the more it absorbs the light of a corresponding specific wavelength (Beer-Lambert's law).
Also see OligoScan
Example OligoScan Heavy Metal Test Report. Note that the result values are not of standard units like micro-grams per liter so comparisons with blood tests are futile. Additional OligoScan tests can be merged into comparison reports to track progress. In this example, silver and mercury are elevated which is a key indication that amalgam dental fillings are shedding material which is being absorbed by the body. Note that early chelation rounds may show a slight increases in mercury as a result of mercury mobilization when using EDTA, DMSA, DMPS or ALA. It is only in the later stages of chelation, when the body burden of mercury has been significantly lowered, will the OligoScan measurements start to drop.
OligoScan scans four points on the hand.

Cyrex: Neurological Autoimmune Reactivity Screen (Array 7): This screen test for toxic heavy metals tests one's immune reaction. Blood test examines the associations between mercury biomarkers and antinuclear antibody (ANA) positivity and concentration. The higher the ANA, the stronger the correlation with mercury levels. An autoimmune antibodies test can detect first signs of clinical toxicity by years compared to other screening tests. Your licensed healthcare professional will perform the blood draw and interpret the results. Regulations governing clinical laboratories prevent laboratory personnel from providing technical assistance to patients.Predictive Antibodies:
Tri-Test: All mercury is not equal. Elemental inorganic mercury is far less toxic than organic methyl mercury.
This distinction is found in the Quicksilver Scientific mercury "Tri-Test" which measures mercury in the blood, urine and hair and distinguishes the difference in measurements for elemental inorganic mercury (Hg2) and methyl-mercury (MeHg).
Most traditional tests report "total" mercury rather than individual organic/inorganic mercury levels.
The "Tri-Test" results will also show a plot of urine vs blood levels to show how effective one's body is at expelling mercury.
Also see Quicksilver Metals Testing
Tri-Test results show the contribution of organic methylated mercury (MeHg) and inorganic mercury (Hgll). This also guides one's choice in chelators as DMSA favors the former while DMPS favors the latter. Clearly in this example, MeHg comprises the bulk of the total mercury burden. The total burden (HgT) is also plotted. Note that hair tests do not account for excretion efficience and can be a false negative as a low measurement can reflect the inability to excrete mercury and may be unable to measure a mercury toxic patient or a high body burden of mercury.
Quicksilver mercury Tri-test: includes two blood vials and urine vial, instructions and mail pouches
ACC Counting Rules: The Dr. Andy Cutler Chelation protocol "counting rules" applies to hair element analysis results to determine if one is mercury toxic. One can assume that hair tests only measure toxic metals as a momentary status and not the true toxic body burden measured in one's human tissue. The counting rules use the cumulative results from all metals in order to determine the mercury toxicity status. There is no mathematical basis to support this measurement rule hypothesis nor any peer reviewed research. Also hair tests do not measure the body burden of toxic metals stored in a person's organs and tissue but show the available circulating levels at a given point in time.Counting Rules:
Meeting a rule equates to being mercury toxic.
This test is applied to a Doctor's Data Toxic and Essential Elements Hair Test (not the Hair Toxic Element Exposure Profile).

Boyd Haley has a PhD in biochemistry, was an NIH funded researcher at the University of Wyoming and at the University of Kentucky and professor and is the principal developer of NBMI as a chelator for mercury detoxification and founder of EmeraMed, a biotech firm created with the goal of getting NBMI FDA approved as a treatment for mercury toxicity in both humans and animals. Dr. Haley's protocol is the latest of the mercury chelation protocols and employs a new chelator, NBMI, claimed by its producer, EmeraMed, to not have the mercury mobilization problems and the side effects of some of the more established chelators like DMSA, DMPS, ALA and EDTA. The protocol recommends starting with low doses (25 mg a day) and working on up to 300 mg (or 4 mg/kg of body weight ref) a day. Test data has shown that low doses (100 mg) of NBMI get consumed by the body while scavenging free radicals and it is at the higher doses (300 mg) that noticable mercury chelation occurs (ref). Doses can be administered 1 to 4 times a day as it has an 18+ hour half-life allowing infrequent doses. NBMI can be added to fat (olive oil or corn oil or butter, etc.) to improve absorption. One may even begin using NBMI transdermally by mixing it with olive oil and applying it to one's skin.
NBMI makes a strong bond with mercury and may cause cellular damage when breaking the bond mercury has with a cell and may cause an inflammatory response from the body when it signals the immune system requesting cellular repair. Symptoms may include a knotted tension feeling as the NBMI bonds and removes mercury. Mercury toxic people must start slow with low doses to avoid overwhelming the body. When mercury bonds with NBMI it renders mercury non-toxic and makes an almost unbreakable bond thus it avoids the problems of mobilization and reabsorption common with other chelators. NBMI still possesses its own risks including harm to the brain from the detaching of mercury from brain tissue and inflammation. Chelation is never risk free. Note that NBMI is not FDA approved and there are no independent medical peer reviewed studies on its effectiveness as a chelator to lower the body burden of mercury.Also see:

The ACC protocol addresses the chelation of mercury and the removal from tissue, organs and from the brain. The details of the ACC protocol are covered in the book "The Mercury Detoxification Manual". The ACC protocol can be performed by one's self or by a medical professional. This protocol involves the use of the chelation agents DMSA or DMPS and ALA taken orally in a given dosage and schedule, starting with low "microdoses" and working up to higher doses over time.. The scheduled times are during a full 24 hour day and not just a day time schedule. The schedule is dependent on the half life of the chelation agents to maintain an active level of continuous chelation and mercury removal and missing a dose by an hour or more will require a round to be stopped. The ACC protocol takes a commitment and discipline over the course of a few years. The ACC protocol also has the significant risk of inducing further damage from mercury toxicity because of the use of DMSA or DMPS and ALA chelators which are known to redistribute mercury to the brain and nervous system.
Stage 1 - Body: The protocol begins with a general removal of mercury from the body in at least 3 or 4 rounds (one round = three 24 hour "on" days separated by a four to eleven day "off" period) using DMSA. The schedule for each round is 25 mg as stated on page 65 of the manual or 12.5 mg as stated on the ACC website (editor's note: these are conflicting but high dosages. After a round, patients often recommend a light dosage start at 1 mg or 3 mg) of DMSA every 4 hours (for example: 7am, 11am, 3pm, 7pm, 11pm and 3am) for three days. The dosage can be adjusted higher or lower depending on tolerance. Start with very low dosages so as to not stir up and redistribute too much mercury. The chelators DMSA and DMPS will mobilize and redistribute mercury, so the dosage should be chosen to minimize this effect. Jumping to much higher dosages by more than 50% are NOT encouraged. Tolerated low dosages are best. Fatigue, kidney irritation and symptoms of mercury toxicity are the most common side effects. Repeat the 3 or 4 rounds at higher dosages until you are using a 25 mg dosage of DMSA with few side effects. The dosage should remain steady for the 3 or 4 rounds before an increase is introduced. These initial rounds will lower your body burden of mercury and create a mercury concentration gradient which favors the flow of mercury from the brain to the body rather than vice-versa. The protocol recommends that the patient "Keep the dose low and go slow". While the duration is not specifically stated, it may take many months to achieve your goals.
Stage 2 - Body and Brain: Once you have reached the 25 mg dosage of DMSA, one can then take 12.5 mg ALA and 25mg DMSA every 3 hours for three days "on" followed by a four to eleven day "off" period of no chelation agents. DMSA is used in stage 1 to reduce your body burden of mercury before you start taking mercury out the brain and internal organs with ALA in stage 2. If ALA is not tolerated well, drop the dosage to as low as 3mg. The protocol details schedule changes to accommodate ALA intolerance and getting back on schedule. Note that ALA should not be taken for more than 3 consecutive days. The protocol (30mg DMSA and 12.5mg ALA, or 25mg DMSA and 17.5mg ALA - ref: ACC website) is followed until the target dosage of DMSA and ALA are reached (200 mg ALA/dose for 6 months - ref: ACC website and Detox Manual pg 71). Final dosage of ALA can be more accurately calculated as 3 mg for each kg of personal weight.
The body does not store or release mercury in a consistent fashion, which affects chelation. This manifests itself as inconsistent results and problems round to round. For this reason it is important to find a low and tolerable dosage to repeat for a long duration rather than constantly trying to raise the dosage to optimize progress.
Reintroduction of essential minerals (magnesium: 100-200 mg with meals, zinc: 50 mg/day), vitamins (C and E), essential fatty acids (omega 3) and Adrenal Cortical Extract (ACE) supplement is required to counter the adverse effects of mercury and mercury chelation. The ACC protocol has a schedule and dosage for supplements. One performs a urine or hair sample test for mercury to monitor dropping levels (hopefully). The chelation regiment is repeated until the mercury drops below an acceptably low level. Note that this is purely an indication of mercury levels as true levels in organs and the brain can not be tested. The ACC chelation protocol can last 1 to 4 years.
While this chelation protocol does not have any medical peer reviewed studies as to its effectiveness, there are plenty of medical studies on the effectiveness of the DMSA and DMPS as chelation agents for the removal of mercury. There are also studies which show how these same chelators can mobilize mercury and make the consequences of mercury toxicity worse.Also see:

The PushCatch protocol is for addressing mercury detoxification and uses a combination of R-Lipoic Acid (RLA: nature's version of ALA) chelation, glutathione production and the enzymes that work with it. Dr. Shade feels that reliance on glutathione avoids the half life problem of pharmaceutical chelators as the body regulates the levels in the bloodstream which never go to zero. The focus of this protocol is on liver detoxification and balancing inflammatory pathways. The PushCatch protocol includes a multitude of botanicals (myrrh, dandelion, gentian, goldenrod), liver treatments (nano milk thistle, DIM, quercetin, luteolin, r-lipoic acid), binders (activated charcoal, bentonite clay, chitosan, IMD) and GI lining stabilizers (Fibregum Bio, acacia gum and BiAloe). Dr. Shade's position is that RLA is an NRF-2 (Nuclear factor erythroid-related factor 2, cellular detox gene) upregulator (rather than a chelator) which makes the body produce more glutathione which leads the body to detox in a “natural” way. Dr. Shade also sees RLA as an AMPK (promotes ketosis: cardio and metabolic health) upregulator as well as a PGC-1-alpha (mitochondria biogenesis) upregulator. This protocol encourages the liver to metabolize toxins to dump them with bile into the GI tract where the toxins cling to binders so that they will be evacuated and not re-absorbed.
We feal an obligation to point out that while Dr. Shade can be seen in YouTube videos expressing the "liver sauce" and the "push catch" protocol as a method of detoxifying the body of mercury, there is no statement on the Quicksilver Scientific website or in their "push catch" product literature that makes any such claim. The binder, on the other hand, is advertised to have a high affinity for mercury. There have also been no medical studies published on the effectiveness of this product to remove mercury.Liver Sauce ingredients: (push)
Quicksilver: "Push-Catch" detox
This author wrote his book to de-mystify the process of mercury detoxification. He supports the body's ability to remove mercury in a process that is based on the premise of starting low and go slow. The book is for those who are about to have their dental amalgam fillings removed and want to follow-up and remove the accumulated mercury from their body. It covers all of the nutrients, vitamins, and minerals needed for your body to manufacture enough antioxidants, and other substances, necessary to rebuild and maintain its defense system against the continuous onslaught of mercury, toxins, oxidation, and toxic metals. The book also covers supplements that aren’t considered vitamins or minerals but are essential to overall health and provide the nutritional support for a mercury detoxification program. It dedicates a chapter to monitoring your progress, chelators and oral health. Note that the choice of chelators used by this protocol (cilantro, chlorella, DMSA, EDTA, ALA, RLA) can and will mobilize mercury causing further toxicity and damage.
Tom is also the author of "The Poison in Your Teeth" and "Healthy Teeth - Healthy Body".Also see:
Author: Dr. Tom McGuire DDS
This is the toxicology textbook you will find in most hospital Emergency Rooms and poison centers. The book follows the FDA advisement that dental amalgam exposure is safe and does not lead to poisoning. It does give an exemption for rare cases of immunologic hypersensitivity.
The book does cover mercury chelation with Dimercaprol (BAL) and Succimer (DMSA) and advises for acute and chronic poisoning.
Dimercaprol (BAL): administer for 10 days in decreasing dosages of 5 mg/kg/dose every 4 hrs for 48 hrs, then 2.5 mg every 6 hrs for 48 hrs followed by 12 hr dosages for a week. This regiment was derived from their chelation of lead protocol and is for acute inorganic mercury poisoning. The book noted that BAL should not be used for organic mercury poisoning as it is more likely to do harm by mobilizing mercury to the brain.
Succimer (DMSA): 10 mg/kg orally 3 times a day for 5 days, then twice a day for 14 days if the GI tract is clear. The book recommends Succimer for those who are not acutely ill or who have been chronically poisoned by inorganic mercury. When chelating methy-lmercury (organic mercury), DMSA is credited with a decrease in brain and body mercury which is in contrast with ACC which limits recognized effectivity to reducing body burden only. Note that this guide recommends an extremely high chelator dosage when scaled for body weight, much higher that other protocols like ACC. High initial doses present their own dangers and should be viewed with caution.
The book acknowledges the use of DMPS and D-Penicillamine but states that BAL and DMSA are the treatments of choice and that DMSA is preferred for those who are not acutely ill. Note that their choice of chelators used will mobilize mercury causing further toxicity and damage.

Trial to Assess Chelation Therapy (TACT) was a chelation study sponsored by the US National Institutes of Health (NIH) using disodium ETDTA as the chelation agent to test the safety and efficacy of chelation therapy. Primarily the study determined that it benefited those with coronary heart disease with an 18% reduced risk of a cardiac event and that vitamin and mineral supplements had little effect on the outcome. There were two studies performed, TACT and TACT2. The TACT study found EDTA (NaEDTA specifically) to be a safe chelation agent for adults. The TACT study did not address mercury or Parkinson's disease.Also see:
The various chelation therapy protocols are often in conflict and do not define a consensus leading to patient confusion on such an important issue. Sorry. The patient must educate themselves and chose a path. Local holistic practitioners are often not of much help either as it is easy to educate oneself to a level that only stumps the practitioner when approached with in depth questions. Choose a practitioner who is familiar with the various protocols and not just with the directions on the side of the chelation agent container.

The ACC protocol is suspicious of weak chelators as they may bind to a mercury atom but then not maintain a hold to it in a strong enough bond to journey from the source to excretion from the body. The ACC protocol assumes that weak chelators will not maintain the bond to the mercury atom and will distribute and release mercury to other parts of the body where it may cause even more harm. It must be noted that the chelators used by the ACC protocol (DMSA, DMPS and ALA) will drop and mobilize mercury. All protocols use ALA or RLA to remove mercury from the brain where mercury is causing damage and characteristics of Parkinson's disease.
There is a huge gap in the opinion about chelating with the presence of mercury amalgam fillings. ACC protocol forbids it as they believe that chelators will remove mercury from the fillings and poison your body. The ACC protocol is cautious and does not allow for the use of DMSA until amalgams are removed and forbids the use of ALA until three months after they are removed. The ACC protocol fears that since ALA can cross the "Blood-Brain-Barrier" (BBB), it might pick up mercury atoms in the body and deliver them to the brain. ACC believes in detoxifying the body first and then the brain, all after amalgams have been removed. The Dr Tom McGuire believes in the use RLA/ALA chelators before amalgam fillings are removed to lower the mercury burden as soon as possible. He does hold off on the use of DMSA until after amalgams are removed. Dr Chris Shade does not discuss the topic.
The various protocols have not undergone FDA review, scientific tests or revision to optimize and improve the protocols. Each of the protocols has their pros and cons. If you are lucky enough to find a doctor knowledgeable in mercury detox you will find a full spectrum of treatment offerings from those who merely read the chelator carton directions to those who follow an existing protocol to those customize their own protocols. Dr Chris Shade can be found on video acknowledging that his "push-catch" protocol can be implemented concurrently with Dr Andy Cutler's ACC protocol. This has its merits as the "push-catch" "liver sauce" has many anti-inflammatory ingredients which will help counter the inflammation experienced from chelation agents used in the ACC protocol.

NBMI is an efficent chelator for mercury without mobilization and redistribution issues and can be used initailly to remove mercury upon which time other chelators can be employed to remove other toxic metals.
This website does not endorse chelation or any particular chelation therapy, nor with any particular experimentation of therapies.
The pharmaceutical chelators (ETDA, DMSA, DMPS, etc) are powerful heavy metal detox agents but, if misused, can have high risks of generating more damage than if never applied. Some "over the counter" supplements can act as chelators and while they have a less powerful effect, they are not immune from hazard.
|Garlic|| study suggests that raw garlic provided protection from mercury by affecting both its assimilation and elimination.
Garlic also helps replenish sulfur body stores.
When sulfur stores are depleted, it impairs chelation effectiveness with sulfur chelators like DMPS or DMSA as they are metabolized and utilized as a source of sulfur.
|Modified Citrus Pectin (MCP)|| a gelatinous polysaccharide and soluble fruit fiber altered to be more digestible. A small study shows that it was effective in lowering blood lead levels while increasing urine lead levels.
No results shown for mercury.
Product available from EcoNugenics: PectaSol
|Selenium|| Found in Brazil nuts, seafood and mushrooms, selenium increases mercury excretion and decreased markers of inflammation and oxidative stress.
Selenium can also be toxic so avoid overconsumption (recommended adult allowance: 55 mcg/day, Tolerable upper limit: 400 mcg/day ref NIH)
Brazil nuts are high in selenium. A serving of 3 nuts contains almost 400% daily value.
|Taurine|| is a compound containing sulfur and has shown to be protective in rat studies.
|Chlorella|| is an algae rich in chlorophyll, often promoted for its ability to chelate mercury and other heavy metals.
The following mouse study shows significant increases in the cumulative Hg eliminations into urine and feces.
Chlorella has been disavowed by the ACC protocol as it may cause mercury redistribution.
There are many sauna based heavy metal detoxification facilities and one has to be skeptical of many claims but research does support claims that sweating deserves consideration for mercury and toxic element detoxification. Sweating can also be acheived by endurance exercise which has been shown to be more effective than intensive exercise. One must take care not to get dehydrated or salt, potassium and electrolyte depleted as this can be hard on the kidneys.
The human body has mechanisms to chelate mercury naturally, but it's not very effective at handling a high toxic burden. The body protects itself with the sulfer-hydrogen (SH) compounds Metallothionein and Glutathione.
Metallothionein (MT) is cysteine-rich and found intracellularly and can bind both essential and non-essential heavy metals.
Glutathione (GSH: γ-glutamyl-cysteinyl-glycine) is a natural anti-oxidant found in plants and animals. It too has a cysteine thiol group (SH) group which acts as an electron donor when binding to heavy metals (Cu, Hg, Cd, and Pb). Glutathione is poorly absorbed by the body and thus does not work well as an oral supplement. Precursors to GSH (NAC, glycine and glutamine) can be taken as supplements to suport the generation on GSH by the body. The ACC protocol recommends against the use of the GSH pathway as it mobilizes mercury and can reabsorb it in the GI tract (unless an absorbant binder is employed) while the Dr. Chris Shade protocol and some research has been in favor.
Neither are strong chelators as they form weak bonds comapared to pharmacutical chelators (eg DMSA, DMPS, ...). The half life of mercury when relying on natural, unassisted chelation by the human body, can be decades.
Note that when one is mercury toxic that glutathione will prefer bonding with mercury, allowing a buildup of other toxic metals such as aluminum and lead. Detoxifying one's self of mercury will help in the detoxification of other toxic metals.Also see:
Chelation therapies can remove the intended "bad" heavy metals like mercury but it will also deplete the human body of essential minerals and metals. It is essential that these be reintroduced to the body as they are essential for mental health and system regulation. It may even take longer to reintroduce the required nutrients than to remove them. Thus if done improperly, chelation can result in gradual system decline and deleterious effects.
The dosage and rate of intake of chelation agents is also important. Too much and the body may experience the toxic effects of mobilized mercury separated from body tissue. Dosage timing is also important as chelation agents are bonding with the mercury, but stopping at the wrong time may just dislodge the mercury without excreting it, causing the mercury to potentially relocate. One study found that chelation elevated mercury in the circulatory system which in turn elevated mercury levels in motor neuron axons across the neuromuscular junction. Elevating the levels of mercury in motor neurons will only contribute to their decline and exacerbate Parkinson's symptoms. The manufacturer of Emeramide/NBMI claims that mercury mobilization, while a problem for DMSA, DMPS, ALA and EDTA, is not an issue for NBMI.
Intravenous chelation therapies can result in a burning sensation at the site of injection. Aggressive use if chelation agents can induce vomiting, headaches, nausea, low blood sugar symptoms and blood pressure changes.
Challenge tests with a high single dosage of a chelation agent are sometimes given by clinicians to show that they can remove mercury by showing an increase of mercury in a urine test. This is often not safe as it can result in adverse effects and a spike in mercury in the system which gets relocated rather than removed.
Chelation therapy has risks including anxiety, psychosis, brain damage, liver damage, kidney damage and death. This is most often accomplished by doseages which are too high or administered over a long period of time. The chelators can mobilize mercury and at times will add to the mercury toxic burden in the brain. There is no way to control the random nature in which a chelator will mobilize mercury or the relocation of this mobilization. The assumption is that chelation will remove mercury over a long period of time but there is no certainty as to the benefits or damage caused during this time. This webiste does not endorse chelation or any specific product, service, or treatment due to the extreme danger and harm that chelation can present.Also see:
Chelation therapy will grab mercury from your body, bond to it so that the resulting molecule can be evacuated by the kidneys and liver. There is the danger that when evacuated by the liver through the bile duct into the Gastrointestinal (GI) tract, that mercury can be re-absorbed in the small intestine and colon. The GI tract is about 26 feet long and giver mercury a chance to be re-absorbed into the body. To mitigate this effect, binders are often taken to absorb and attach to toxins to help the GI tract fully expel them. Binders can also be taken at the time of amalgam removal in case any is ingested. Note that if a binder is taken at the same time as a chelator or supplement, the binder may remove that too. Binders should be taken on an empty stomach, between meals or in a fasted state.
Binders include activated charcoal, bentonite clay, zeolite (sodium aluminosilicate) and chitosan as well as combinations of the aforementioned substances. Activated charcoal tends to remain in the GI tract as is true of large particles of zeolite. Small "nano" particles of zeolite on the other hand will pass into the bloodstream and travel through the body and act like a chelator and will posess the same mercury redistribution pitfalls as a chelator.
Zeolite is a porous volcanic mineral with a unique and complex honeycomb crystalline structure which can trap toxins. Before using for human consumption, zeolite must be cleansed of the metals it has trapped in its cavities over the years in nature. Zeolite also uses its natural negatively charged mineral structure to draw toxins to it.Also see:

If one has a glutathione transferase (GST) polymorphisms, they may have a decrease in the body's ability to clear heavy metals like mercury. Patients with GST enzyme abnormalities may want to consider receiving glutathione to expedite excretion of chelated metal. Patients with the GST polymorphisms also tend to excrete mercury later in their course of treatment than other heavy metals. This can produce early false negatives for mercury, due to preferential excretion of lead and other metals.

While DMSA and ALA may not directly remove lighter nutrient minerals, those high in mercury often experience low levels of magnesium and zinc. The ACC protocol suggests the following four "core" supplements while chelating:
|Vitamin C (buffered)||1000 - 2000 mg 3X or 4X/day
250 - 500 mg/chelator dose
|90 mg||The buffered variety is easier on the stomach and helps avoid heartburn.|
Dr. McGuire: 1000 mg 3X/day
Warning: doses of greater than 2000 mg/day may lead to kidney stones and severe diarrhea (WebMD)
|Vitamin E||1,000 IU/day||15 mg
|Note that too much vitamin E can accumulate in body fat, cause blood thinning and bleading.
Vitamin E is an antioxidant which protexts cells from the damaging effects of free radicals.
Vitamin E refers to a group of eight compounds: alpha-tocopherol, beta-tocopherol, gamma-tocopherol, delta-tocopherol, alpha-tocotrienol, beta-tocotrienol, gamma-tocotrienol and delta-tocotrienol of which there are synthetic and natural formulations.
Gamma-tocopherol is the most prevalent form of vitamin E and is found in plant seeds, vegetable oils and nuts (pecans, almonds, sunflower seeds, walnuts).
Gamma-tocopherol has anti-inflammatory effects and is linked to a reduction in cancer and cardiovascular disease risk.
Warning: high doses can be associated with increased concentration of creatine in the urine (creatinuria) and increased risk of bleeding.
|Magnesium-L-Thorate||100 - 200 mg 3X or 4X/day||420 mg||For more information see magnesium supplements
Warning: doses greater than 350 mg/day may lead to irregular heartbeat, low blood pressure, confusion, and may build up in the body causing coma and death (WebMD)
|Zinc||50 mg/day||11 mg||Considered an essential mineral which can not be fabricated by the human body. Supplementation of zinc often results in copper deficiency as the two compete for absorption. Zinc supplementation may require copper supplementation (zinc/copper supplement ratio: 15/1).
Warning: high doses of 100mg/day or more for 10 or more years doubles the risk of developing prostate cancer. Doses of 10,000 mg or more can be fatal (WebMD

Dr. McGuire's guide has detailed information on brain supplements and a tolerance testing regiment.
The body is use to obtaining nutrients with food and thus it is most natural to the body to take supplements with meals. Consumption of water is also very important as it helps flush waste and toxins from cells, helps eliminate toxins from the bloodstream and supports kidney and liver function.
It is important to monitor your body with frequent blood tests while chelating to make sure you are not damaging any organs. Dr. McGuire's guide recommends blood tests, fecal tests and a symptom evaluation every three months to monitor your detox program (chapter 8).

It has been suggested in the ACC detoxification protocol that when experiencing both adrenal and thyroid problems, one should address the adrenal problems first. Adrenal support for those experiencing lethargy, can be helped by taking the supplement adrenal cortex (without adrenal medulla which contains adrenaline which can cause mood and behavior disorders).
Blood draws to test liver, kidney and thyroid function.
It is important to monitor how much mercury is being removed by the chelation therapy. You have reached the successful completion of treatment when the chelator is no longer removing mercury because there is no more to remove.
The ACC protocol suggests a hair test and has published a book specifically on the topic of interpreting hair analysis results. The Detoxification Manual also covers "counting rules" to help interpret the test results and to help determine if you still have toxic levels of mercury remaining. This protocol also suggests that if you are feeling the discomfort of chelation, that mercury is still being removed from your system.
Dr. Chris Shade's Quicksilver website sells a mercury "Tri-Test" which is available to doctors and tests mercury in the urine, hair and blood to determine the body's mercury burden and its ability to eliminate it. It is a unique test that measures methyl mercury and inorganic mercury separately.
The Dr. Tom McGuire protocol uses a fecal test every three months at the end of a three day chelation period. This protocol has chosen a fecal test because 90% of the eviction of mercury is through bile and the intestine. He also does not believe in employing the hair test as he feels that it measures organic methyl mercury and will not include the elemental mercury indicative of the mercury contributed by amalgam fillings. Note that it is not safe to chelate while mercury amalgam fillings are still present in one's teeth. When the mercury level tested reaches a low steady-state measurement, you have reached completion.
Neither blood, urine stool or hair tests are good at measuring the body burden of mercury lodged in mostly fatty tissue, they mearly measure the mercury circulating at any given time due to mercury ingested. The OligoScan mentioned above measures body burden directly. While the OligoScan measures mercury in one's hand, there is nothing short of an autopsy which can measure mercury in the brain and nervous system.
