Most people are mercury toxic. Mercury is among the most toxic elements known. In this article, I reveal how to reduce exposure and remove it from our bodies.
Mercury in our environment is contributing to countless chronic health problems today, especially for those who:
- Eat fish or shellfish at least twice weekly
- Has had or has mercury amalgam fillings
As a result of all this exposure, most children today are born with excessive mercury in their bodies. Mercury is a factor in increasing birth defect rates, autism and other developmental delays, ADHD and other learning disorders. Mercury easily passes through the placenta from mother to child. This source (congenital mercury) can be reduced if women reduce their mercury burden before becoming pregnant.
SOURCES OF MERCURY
There are three different kinds of mercury:
- Organic (methylmercury): Methylmercury is naturally occurring and bioaccumulates in the environment, especially in fish. As a result, most human exposure to organic mercury comes from eating fish (17, 19).
- Inorganic: Inorganic mercury is most typically found as a white powder and can be found in products such as disinfectants and fungicides (19).
- Elemental mercury: This is form of mercury is a metallic, silvery liquid and what you would find in a thermometer (19). It’s also found in dental amalgams (17). According to the NY state Department of Environmental Conservation, elemental mercury “is a potent neurotoxin that impacts the central nervous system” (19).
Mercury can invade our body in many ways. Here are a just a few of the sources in which it lurks:
- Dental mercury amalgam fillings (15)
- Fish and shellfish (especially tuna, shark and other large fish) (15, 17, 18)
- Vaccines (18)
- Disinfectants (19)
- Fungicides (15, 19)
- Soft contact lens solution and eye drops to reduce redness
- Latex and oil-based paints
- Nasal sprays
- Adhesives (15)
- Air conditioner filters
- Air pollution (coal burning) (18, 19)
- Battery manufacturing
- Body powders
- Bleached flour
- Broken thermometers
- Burning of building materials
- Calomel lotions
- Some Chinese herbs
- Cleaners including Ajax, Lysol, Comet, Derma Scrub, Dove Soap, Ivory Liquid
- Chlorine and chlorine bleach (15)
- Coal burning (this is how mercury is released into the environment)
- Congenital intoxication (acquired in utero)
- Embalming fluid
- Engraving supplies
- Exhaust fumes
- Fabric softeners (15)
- Felt (15, 19)
- Industrial waste (15)
- Paper manufacturing
- Photo engraving
- Preparation H
- Psoriasis ointment
- Sewage disposal and sludge (15)
- Skin lightening creams
- Water (contaminated)
- Waxes (including floor) (15)
- Wood preservatives
Mercury can be found in many prescription, over-the-counter drugs and personal care products. Mercury is used because it is an excellent germ killer.
Thiazide diuretics, used to lower blood pressure, contain mercury. Other products that may contain mercury include antiseptics, anti-fungal preparations, soaps, contact lens solutions, etc.
Studies demonstrate that each time one bites down on a mercury filling, some mercury vapor, the most dangerous form of mercury, enters the body. The amount that escapes is tiny, but it occurs thousands of times each day. Mercury fillings that have been in your mouth for more than 15 years degrade at a faster rate. This mercury vapor travels directly to bodily tissues and the brain, an organ easily damaged by mercury. (15, 17)
Large Fish And Shellfish
The major source of mercury exposure for most are fish and seafood. In particular, large fish that eat smaller fish concentrate mercury up to one million times in their body fat and other tissues. Tuna fish is the most widely enjoyed toxic fish. However, all fish, no matter what their size, are contaminated with mercury.
Shellfish, including clams, mussels, oysters, lobster and shrimp all tend to have mercury and other toxic metals such as cadmium, arsenic, lead, and even radioactive waste and other contaminants. This makes them basically unfit for human consumption.

Mercury is used in industry and manufacturing as a germicide, fungicide, an electrical conductor and more. These industries include electronics, gold mining and the manufacture of paper, chlorine, adhesives, fabric softeners and waxes.
Hundreds of symptoms may be due to chronic mercury toxicity. The organ most affected is often the brain, and children suffer the most from many mercury-related disorders.
Here is a long list of symptoms and conditions that may be associated with mercury:
- Acid Reflux – mercury is a proton pump inhibitor, which reduces stomach acid
- Adrenal fatigue

Blood tests are practically useless to detect mercury unless you’ve had a recent exposure because the body removes mercury from the blood to store it away from vital organs. Mercury is stored in the tissues of the brain, kidneys and liver. The best methods of detection for mercury are hair mineral analysis and urine metals push tests using chelating agents that favor mercury.
Hair Mineral Analysis
As any amount of mercury is toxic, even small amounts of mercury on an HTMA (Hair Tissue Mineral Analysis) is undesirable. Any hair level of mercury above 0.02 mg% is excessive. Mercury does not always deposit into the hair to show on an HTMA. A hair mineral analysis provides many indicators of hidden mercury toxicity even if mercury itself is not presenting on an HTMA. These include:
- An elevated copper above about 2.5 mg%. Mercury toxicity is usually found if copper toxicity is present.
- Hidden copper toxicity indicators such as a high hair calcium, a low hair potassium, a low sodium/potassium ratio and a low zinc level. For more on copper, read Copper Toxicity Syndrome.
- Elevated levels of cadmium, arsenic or aluminum often indicate the presence of hidden mercury.
A Urine Toxic and Essential Elements Test is another way to detect the presence of mercury. Some people are not able to detox mercury into the hair. By using chelators like DMSA or cilantro extract, you can ‘push’ mercury, and many metals not on an HTMA, into the urine and get a good picture of the body burden of mercury. I prefer to use both methods, urine and hair mineral analysis, to determine one’s toxicity levels.
Reduce Fish In Your Diet
To reduce mercury exposure, completely avoid tuna fish and larger species of fish. Other fish known to be high in mercury include sea bass, marlin, shark, halibut, pike, walleye, swordfish and bass. Also, it is best to avoid slightly less contaminated fish such as mahi mahi, cod, pollack, salmon from the Great Lakes, channel catfish (wild) and lake whitefish.
Fish that are considered safer include trout (farmed), catfish (farmed), fish sticks, flounder (summer), sardines, mackerel, anchovies, salmon (wild Pacific), croaker and haddock.

Avoid All Shellfish
Mercury is just one reason to avoid all shellfish, even though they are tempting and formerly were one of my favorite foods. Shellfish are also often high in cadmium, nickel, arsenic, aluminum and many toxic metals found in the coastal shelves of every nation.
Replace Dental Amalgams
I advise anyone with mercury amalgam fillings to have them replaced, preferably by a biological dentist. I don’t recommend doing this all at once, but doing a few fillings at a time in stages. Mercury amalgams undoubtedly leach mercury into your body, but also contain nickel, tin, aluminum and sometimes palladium – all toxic metals. Mercury fillings older than 15 years ten to leach more metals into the body as they become less stable over time.
REDUCING MERCURY IN YOUR BODY
Myers Detox is a proven method to remove mercury from your body, in addition to all toxic metals and hundreds of chemicals. It does this by the following methods used in an integrated way that safely and completely detoxes the body. These methods include:
1) Infrared Saunas. The skin is the largest organ of the body and an excellent eliminative route for mercury. The best way I have found to enhance skin elimination is daily use of an infrared sauna for several years. After this period, one only needs to use a sauna several times a week. (8)
2) Mineral Supplement Antagonists. Mercury antagonists such as selenium, zinc, chromium and manganese assist to remove mercury from the body. Selenium is the most important to remove mercury. I have found that almost everyone I test is deficient in selenium.
3) Binders. Mercury can be removed by use of CitriCleanse, which is grapefruit citrus pectin. This natural product is amazing at absorbing metals like mercury that are mobilized on a Myers Detox program.
4) Chelators. Chelators bind to metals to remove them from the body. Chelators effective for mercury are cilantro extract, Intestinal Metal Detox by Quicksilver, Super R-Lipoic Acid, Curcumin, garlic and N-Acetyl Cysteine. I recommend these to anyone with mercury toxicity.
DMSA is a synthetic chelator that is needed by some people to aid in the removal of mercury and other metals attracted to this chelator (12). Mercury can be difficult to remove from the body – especially if a client is ill, has multiple health conditions, has methylation issues or has weak eliminative detox organs like liver and kidneys. I personally found that natural means were not enough to remove the large amount of mercury I had in my body. I used DMSA to remove the remaining mercury in my body after detoxing using natural methods for four years.
DMSA chelation is shown to reduce autistic symptoms in patients as the blood levels of lead and mercury decrease (11). A 2012 study conculded that, “DMSA chelation increased the urinary output of toxic and neurotoxic metals. Our data supports evidence that detoxification treatment with oral DMSA has beneficial effect on Autism Spectrum Disorder patients.” (14).
Everyone needs to be aware of mercury in their diet and environment and take preventive steps to reduce exposure and mercury levels currently in their bodies. By combining the above methods employed by a Myers Detox Protocol, mercury can be removed slowly and safely.
