Mercury and Parkinson's Disease:

Mercury is toxic to the human body and specifically to motor neurons which when 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 can enter the body in many forms:
  • Elemental mercury (Hg): gas or liquid state. Gaseous state is particularly dangerous as about 80% of inhaled vapors are absorbed by the lung tissues. It is also highly fat soluble allowing it to pass through cell membranes and the blood-brain-barrier. Once embedded in the brain, it can disrupt normal function. Also used in dental fillings
  • Organic mercury (MeHg or CH₃HgX): produced when elemental mercury is methylated by intestinal and oral bacteria. This is also known as "Methyl-mercury" and is dangerous as it is easily absorbed. MeHg can bind to the sulfur-Hydrogen (SH) group of cysteine, cross the blood-brain barrier to disrupt glial cells and neurons in the brain.
  • Inorganic mercury (Hg(II), HgCl₂, HgO, ...): produced when elemental mercury oxidizes. Also known as "reactive gaseous mercury" or "divalent mercury". Not fat soluble so it can not pass into cells or the brain but can form strong bonds with enzymes and tissue making it difficult to remove once attached.

The most common toxic form being 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:
  • dental amalgam silver-mercury fillings: inhaled mercury vapor
  • fish, especially carnivorous fish at the top end of the food chain or those with long life spans: shark, sword fish, halibut, orange roughy, king mackerel, tuna, marlin, bluefish, grouper
  • thimerosol: a vaccine preservative, an anti-fungal agent, antibacterial preservative for antiseptic ointments, creams, jellies, nasal sprays, eye drops, contact lens solutions
  • tattoo ink
  • broken CFC light bulbs, fluorescent lamps, neon signs, mercury vapor lamps
  • broken mercury thermometers, barometers, blood pressure meters
  • mining: used to remove gold
  • electrical switches

Amalgam Dental Fillings:

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. Acids found in foods and drinks (especially if they are hot) can cause the release of Mercury from the amalgam.

Amalgam dental 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. 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)

Safe Mercury Amalgam Removal Technique:

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:
  • the use of a dam around the teeth being worked on to trap debris from being ingested by the patient
  • the irrigation with cold water during removal to minimize the generation of mercury vapor
  • the use of amalgam capture separators to capture material so that it is not released into the public waste system or atmosphere
  • the use of an evacuation system to remove mercury dust and vapors from the patient's mouth
  • the use of an air supply so the patient does not breathe in mercury vapors
  • the physically coarse mechanical removal of chunks of amalgam rather than just the use of a fine drill which is more prone to generate fine particles of mercury, mercury dust and mercury vapor
  • the use of ambient high volume air filtration equipment to trap mercury dust and vapors
  • provide the patient a charcoal slurry binder (or equivalent) to rinse and swallow before and after the procedure
  • provide the patient and dental workers protective gowns
  • provide the dental workers protective face shields, head coverings, non-latex nitrile gloves and mask
  • dentist should use equipment optimized to reduce aerosols, minimize and capture vapors and particles. For example the Zyris "Isolite" dentist drill minimizes aerosol and spatter, evacuates vapors and particles and isolates the work area.

IAOMT Safe Mercury Amalgam Removal Technique (SMART) protocol

Amalgam fillings can be replaced with porcelain inlays or onlays bonded to the tooth. 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.
Dental materials testing panel: Clifford Consulting and Research (get tested for BPA and other dental materials)

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.

Mercury Removal/Chelation from Human Tissue and Organs:

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 ligand (molecule that binds to a central metal atom by donation of one or more of its' electron pairs) that form bonds 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 and feces.

Chelation Agents:

Chelation AgentFDA ApprovedDescriptionToxicity (LD50) mmol/kg (lower=more toxic)
DMSAyes 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 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). 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. Half life: 4 hrs.13.58
DMPSno 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 poisoning. DMPS favors inorganic mercury. 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. Half life: 8 hrs5.22
EDTAyesEthylene 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. 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 Andy Cutler it can form a dangerous compound when it binds with mercury. There are two versions, NaCaEDTA and NaEDTA of which NaEDTA easily binds with calcium and should not be used on children. Typically administered intravenously and not intramuscular.10
ALAno 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. Must wait three months after amalgam removal before starting chelation with ALA. Excretion pathway: liver. Half life: 3 hrs
Also see:
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 typically generated by cells in the body as a natural detoxifying agent. Glutathione is often not considered a true chelation agent because they do not contain two or more binding groups (dithiol groups). ACC protocol considers Glutathione IV a dangerous option as it will redistribute mercury causing more damage rather than remove the mercury from the body. Excretion pathway: liver.
Also see Precursors to Glutathione
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 ressulting 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.

Also see: Chelation in Metal Intoxication (2010) covers chelation agents, combinations of agents, pros, cons, limitations, etc

Chelation therapy must be avoided prior, during and immediately after amalgam replacement. 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 poisoning. Also note that dental amalgam replacement can 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 a 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. 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. Chelation can present its own hazards. If chelation is causing pain, severe anxieties or depression, brain fog, head aches or discomfort, stop chelating as the dosage is too high! Chelation is not benefit the patient who is tough or is content with suffering as it may be doing damage. Go slow with light 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 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. Dangers of chelation are discussed in detail below.

Mercury

Chemistry of Dithiol Chelators:

The dithiol (two thiol organosulfur compounds of S-H) group of chelators (DMSA, DMPS, ALA, 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. 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.

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.

DMSA chemical reaction with Mercury Ratio DMSA:Hg shown is 1:1. Other ratios have been found (eg 2:2) but they are not typically long lived.
For other configurations see Mercury binding to the chelation therapy agents DMSA and DMPS and the rational design of custom chelators for mercury (PDF)

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). 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).

Challenge Tests:

Many medical practitioners will want to perform a "challenge test", also known as a "provocation test" or "mobilisation 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.

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".

Measuring Mercury Burden:

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. 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 acceptible 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 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.

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

The OligoScan is a toxic metals scan which unlike the blood test is very imprecise in its measurement of mercury but it 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).

Dr. Andy Cutler PhD chelation (ACC) Protocol:

The ACC protocol addresses the chelation of mercury and the removal from tissue, organs and from the brain. 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. 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.

Stage 1: The protocol begins with a general removal of mercury from the body in 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 6 mg 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 mercury. Jumping to much higher dosages by more than 50% are NOT encouraged. Tolerated low dosages are best. Fatigue is the most common side effect. Repeat the 3 or 4 rounds at higher dosages until you are using a 25 mg dosage 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.

Stage 2: 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. If the 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).

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 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 3 years.

Dr Chris Shade's Push Catch Protocol:

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.

Dr Tom McGuire's Mercury Detox Process:

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.

Tom is also the author of "The Poison in Your Teeth" and "Healthy Teeth - Healthy Body".

Goldfrank's Toxocologic Emergencies:

This is the toxicology textbook you will find in most 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.

Trial to Assess Chelation Therapy (TACT):

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.

Comparison of Chelation Therapy Protocols:

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. 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 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.

 

Sauna Based Chelation:

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.

While studies show that saunas are a valid detox method, it turns out that Ionic Footbaths did not get a positive review:

 

How the Human Body Chelates Naturally:

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 recomends against the use of the GSH pathway 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, can be decades.

Dangers of Chelation Therapy:

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 the 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.

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 and death. This is most often accomplished by doseages which are too high. This webiste does not endorse any specific product, service, or treatment.

Binders:

Chelation therapy will grab mercury from your body, bind 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 (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.

Genetic Link To Deficiency To Clear Heavy Metals Like Mercury:

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.

Suplementing Your Body During Chelation:

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:

SupplementACC DoseDVDescription
Vitamin C (buffered) 1000 - 2000 mg 3X or 4X/day
or
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
30 IU
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.

 

Monitoring Your Body During Chelation:

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 recomends 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).

 

Monitoring Mercury Chelation:

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. This may be a mute point as 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.


Chelation Pros:
  • The extraction of mercury from the human body will help reduce its neurotoxic effects.

Chelation Cons:
  • While some chelation agents are determined to be safe by the FDA, the chelation agents can invoke an allergic reaction, nausea, dizziness, headache and discomfort in some patients. Chelation agents bind to mercury and mobilize it so that the kidney and liver can excrete it. There is always the danger that the chelation agent will "drop" the mercury in an undetermined and unexpected part of the body including motor neurons where it may cause new damage. High levels of chelation can disrupt and disperse enough mercury to be considered toxic.
