Heavy Metal Toxicity: Where Exposure Comes From and What to Do

Heavy metal toxicity isn't just an industrial hazard. It's a widespread, underdiagnosed contributor to fatigue, brain fog, hormone disruption, and chronic illness that affects far more people than most conventional providers recognize.

The Most Common Heavy Metal Exposures

Lead — Found in paint in homes built before 1978, old plumbing, some imported ceramics, and contaminated soil. Children and adults in older housing are at significant risk. Lead has no safe exposure level and accumulates in bone tissue over decades.

Mercury — The primary source for most people is dental amalgam (silver fillings) and certain fish, particularly large predatory species like tuna, swordfish, and shark. Mercury is a potent neurotoxin.

Arsenic — Found in contaminated groundwater, certain rice (particularly brown rice and rice products), some apple juice, and non-organic chicken. Chronic low-level arsenic exposure is carcinogenic and disrupts thyroid function.

Cadmium — Found in cigarette smoke (including secondhand), conventionally grown vegetables (from phosphate fertilizers), and some industrial exposures. Cadmium accumulates in the kidneys and disrupts calcium and zinc metabolism.

Symptoms of Heavy Metal Toxicity

Heavy metal toxicity is insidious because it mimics many common chronic conditions:

• Chronic fatigue and low energy
• Brain fog and memory problems
• Headaches and migraines
• Peripheral neuropathy (tingling, numbness)
• Mood disorders — depression, anxiety, irritability
• Hormone disruption and infertility
• Kidney and liver dysfunction
• Autoimmune activation
• Hair loss
• Digestive dysfunction

How Heavy Metals Are Tested

Standard blood tests only detect recent, acute exposures — because metals quickly move out of the blood and into tissues. For chronic exposure, more informative testing includes:

Hair Tissue Mineral Analysis (HTMA) — a non-invasive test that uses a hair sample to reveal months of mineral and heavy metal data. It captures what blood cannot. (Read more in our HTMA article.)

Provoked urine testing — using a chelating agent to pull metals from tissues before testing, for a more accurate picture of body burden.

At Full Circle Function, we offer HTMA and can coordinate provoked urine testing as part of a heavy metal evaluation.

What Is Chelation Therapy?

Chelation is a medical treatment where a chelating agent — a molecule that binds to heavy metals — is administered IV to remove metals from the body. Common chelating agents include EDTA (for lead, cadmium, and some mercury), DMPS, and DMSA.

IV chelation at Full Circle Function is done under medical supervision with proper pre-testing, monitoring, and mineral replenishment, since chelation removes beneficial minerals alongside toxic metals.

Oral supportive protocols using nutrients like alpha-lipoic acid, NAC, chlorella, and modified citrus pectin can also support ongoing detoxification between chelation sessions.

Frequently Asked Questions

What are the symptoms of heavy metal toxicity?

Symptoms include chronic fatigue, brain fog, headaches, memory problems, mood changes, peripheral neuropathy, hair loss, and hormone disruption. These overlap with many common conditions, making testing essential for identification.

How do you test for heavy metal toxicity?

Blood testing only detects acute exposures. For chronic exposure, Hair Tissue Mineral Analysis (HTMA) and provoked urine testing (after a chelating agent) are more informative methods used in functional medicine.

What is chelation therapy?

Chelation therapy uses IV chelating agents like EDTA or DMPS to bind to heavy metals in the body and remove them via the urine. It is performed under medical supervision with monitoring and mineral replacement.

Is chelation therapy safe?

IV chelation is safe when properly supervised by a trained medical professional. Pre-testing, monitoring, and mineral replenishment protocols are essential. At Full Circle Function, chelation is done under the supervision of Laura Burton, NP.
