Welcome to Maybe It’s Mercury — a supportive, science‑aware space for people who want clear answers and practical steps. If you’ve landed here because of nagging fatigue, brain fog, anxiety, or mysterious aches and pains, or any combination of the more than 250 symptoms that mercury can cause, you are not alone. Mercury exposure is more common than most of us realize, and its effects can look like many other conditions. This guide pulls together what matters: how to recognize mercury poisoning symptoms and how to recover.
Millions are exposed to mercury every day through dental amalgam (“silver”) fillings, seafood, environmental pollution and medical products. The result can be a slow, sneaky build‑up that interferes with your brain, nerves, hormones, and immunity.
Mercury causes an enormous number of symptoms, and any person may suffer from some or many of them. Some feel “wired‑and‑tired” anxiety and insomnia; others feel depressed, foggy, and drained. Digestive troubles, headaches, autoimmunity, neuropathies, mental illnesses can all be part of the mercury picture.
Your body has resilient detox systems. Extracellular mercury is available to these detox systems and lowering exposure, sweating, and taking supportive supplements can often give some relief from symptoms. But ultimately, the only way to get mercury out of your organs and cells, where it is doing long term and chronic damage, is through “chelation” with an appropriate dithiol molecule.
Use this guide to map your next steps, from symptom recognition to safe detox strategies and medical guidance. Then continue with our companion articles on the causes of mercury poisoning and natural recovery strategies. For more resources, visit [Maybe It’s Mercury].
Mercury can cause over 250 different systems. No one gets all these symptoms at once, but even a handful can be a clue, especially with a clear exposure history.
Chronic fatigue or “energy crashes” despite adequate sleep
Headaches or migraines, often worse after stress or certain foods
Metallic taste in the mouth, especially after dental work or chewing
Digestive issues: bloating, constipation/diarrhea, reflux, food sensitivities
Muscle pain or weakness, cramps, or exercise intolerance
Joint stiffness and aches without clear injury
Skin issues: rashes, itching, acne flares, redness
Sensitivity to smells/chemicals, perfumes, or fumes
Heart palpitations or irregular heartbeat sensations
Brain fog, trouble focusing, short‑term memory lapses
Tingling or numbness (hands, feet), “pins and needles”
Fine tremor or shakiness, especially under stress
Coordination issues or feeling off‑balance
Light and sound sensitivity
Sleep disturbances (racing thoughts, insomnia, non‑restorative sleep)
Head pressure or dizziness
Anxiety or panic, especially without a clear trigger
Irritability and mood swings
Depressive symptoms, low motivation or apathy
Heightened stress reactivity; feeling “on edge”
Social withdrawal or reduced resilience
Mercury problems may be taken for thyroid issues, adrenal dysfunction, depression/anxiety, IBS, or menopause, rather than the underlying cause for all these which may very well be mercury. These conditions get treated which in the end is only symptom control.
The blood and urine tests that doctors normally use are best for acute exposure and will miss long‑term body burden.
Many clinicians are only trained to recognize acute exposure as for instance from an industrial accident. Chronic, long-term exposure passes under the radar.
Do you have a lot of amalgam (“silver”) fillings; any recent drilling or polishing can indicate an acute exposure.
Review your seafood intake (especially large predatory fish like : tuna, swordfish, king mackerel or shark) Here is a book about this topic: Diagnosis Mercury, by Dr. Jane Hightower.
Consider environmental factors: broken thermometers or CFL bulbs, occupational exposure, proximity to industry.
Consider iatrogenic exposures. Some medical products are preserved with mercury compounds.

Blood mercury reflects recent exposure and only shows up for a few months.
Urine (with or without chelator): only gives information about extracellular mercury already on its way to be excreted. “Provoked urine tests” are uninformative and can cause side effects because of the bolus dose of chelators.
Hair mineral analysis: A high mercury bar on an HTMA reflects a mercury burden. But often the mercury bar will be low because you are not excreting it. We look for unusual patterns in the essential elements that indicate that mercury is interfering with mineral transport across cell walls.
Clinical judgment: There is no lab test that can tell you how much mercury you started with or how much you have got rid of. You must consider your history of exposure to evaluate how toxic you are, and your pattern of symptoms to judge your progress detoxing.
> Tip: In Amalgam Illness, Andy Cutler has a weighted checklist of symptoms that you or your doctor can use to diagnose mercury. There is also a list of anomalies that can show up on lab tests that a doctor might otherwise overlook. You may already have these tests in your medical files.
Start taking: “The Core Four” which are vitamin C, magnesium, vitamin E and zinc. These should be taken by anybody who has a mercury problem.
Pretty much everyone with mercury problems will also benefit from adrenal and liver support. The main supplements for this are adrenal cortex and milk thistle extract. Once again the information is here.
Binders (fiber, pectin, charcoal) will not help with mercury excretion, but they are okay to use if they help with symptoms. - timing matters to avoid nutrient interference. Chlorella is harmful for mercury toxic people.
ALA, DMSA, DMPS are actual chelators and ultimately must be used to get mercury out of the organs and cells.. They should be used only once you have the knowledge how to use them properly.
For most people “ongoing exposure is their amalgam fillings. To replace these, choose a “biological dentist” trained in IAOMT/SMART‑style protocols (isolation, high‑volume suction, air filtration, oxygen, etc.). Avoid high-speed drilling by untrained providers, as this can spike exposure.
Shift to low‑mercury seafood (salmon, sardines, anchovies, trout) and limit high‑mercury, large, predatory fish.
Handle mercury‑containing items (CFL bulbs, old thermometers) with great care. Dispose of them properly per local guidance.
Nutrition. What diet is appropriate depends on your personal physiology and individual symptoms. At the very least eat all organic to reduce your exposure to chemicals that your body may have difficulty dealing with.
Sulfur‑rich foods. Some mercury toxic people react badly to thiols, which are a form of sulfur. Consider doing a thiol challenge test because if you are such a person, giving up thiols will help enormously with symptoms. You will need the book, The Mercury Detoxification Manual to learn about this test.
Exercise. Although exercise is universally thought to be a good thing, toxic people often have “post exertional malaise” due to poor adrenal function. Be careful with exercise and don’t overdo it. Do not try and power through your symptoms. “Slow and steady wins the race.”
Sleep & Stress: When you have chronic mercury, your adrenal system is invariably poisoned. Toxic people often have every form of insomnia that nature can think up. To sleep better at night, support your adrenals and avoid stress during the day. There are many supplements that help with sleep, and when one stops working (which it very well may) you can switch to another. Ultimately, it is chelating out enough mercury that will make you able to sleep properly again.
Gut Problems. These are perennial with mercury toxic people. Mercury directly poisons the gut, and it also impairs those aspects of the immune system that control yeast overgrowth and parasites. Dysbiosis in toxic people is usually candida and people need to be on yeast killers alternated with probiotics. People with serious gut problems have found the GAPS or similar diets to be helpful.
Environment: Check your environment for mold as toxic people are notoriously susceptible to mold poisoning. Run a good HEPA filter and be sure to change the filters on schedule. Toxic people are often environmentally sensitive so choose nontoxic personal care and cleaning products.
Mercury is famous for causing mental health problems. The opening salvo from mercury, in fact, is usually anxiety and low mood and these can develop into more serious diagnoses. You may need to use anxiolytics or psychiatric drugs to control symptoms until you have detoxed enough that your mood stabilizes. There is no shame in using these medicines if they help and if you are committed to detoxing you won’t need them forever. Certainly pair medicines with mental health support such as: meditation or prayer, talk therapy, supportive communities, and creativity practices.
As the mercury that is hurting you is stored in your brain and sensitive organs, there is unfortunately no lab test to measure before and after burden. You have to evaluate your progress by looking at symptoms.
Keep a diary and track 3–5 core symptoms weekly as well as generally how you feel. We tend to forget bad symptoms as soon as they disappear so a journal is very useful to track progress.
A journal is also useful to keep track of what supplements and meds you are using: when you started and when you stopped them.
1. How long does recovery take? Andy Cutler put a timeline in one iteration of his book Amalgam Illness He told me once that he was sorry he wrote that part. This is because some people start recovering in a few months, and for others the process takes years.
2. Do I have to remove all amalgams? If you are going to chelate, yes you do. You need to remove your amalgam using a trained dentist and you should also post bitewing x-rays of the finished work to our Facebook support group to get the work double checked. Chelating with even a small speck of amalgam in your mouth can be catastrophic!
3. Can mercury cause anxiety or depression? Yes, and this is very often the first symptom that people notice.
4. What foods should I prioritize? This tends to be very individual as one person’s ideal diet may be intolerable to the next. On the whole, we recommend a nutrient dense, organic diet like the one described at The Weston A. Price Foundation.
5. Are saunas helpful? Yes. Sweating excretes extracellular mercury. Only be careful because some cheaper FAR saunas heat unevenly which can stress the body. Be cautious with the sauna. Stay hydrated. If it makes you feel worse, don’t do it.
6. Is chelation necessary? People think that since they got their amalgam fillings replaced, they don’t need to chelate. But removing your fillings doesn’t get rid of all the mercury that has accumulated in your body over the years. Only chelation will do that. So if you still have troubling symptoms to get rid of, you will need to chelate.
7. How do I avoid re‑exposure? Low‑mercury fish, safe dental practices, and mindful home/occupational habits. This article talks about all the ways you can get exposed and “forewarned is forearmed.”[causes](https://www.maybeitsmercury.com/common-causes-of-mercury-poisoning/)
8. Can kids be affected? Reports about the high levels of chronic illness in our kids are coming out. With children, there is plausible route of exposure, and mercury nicely accounts for the wide range of symptoms and conditions.
Mercury can complicate nearly every system — but unlike the chronic diseases it may be mistaken for, it is fixable. Find and end exposure, and chelate with the Andy Cutler Protocol!
