Heavy Metal Toxicity

Lead, mercury, arsenic, and cadmium can affect the brain, nerves, kidneys, and hormones. We assess exposure and support the body in clearing what it carries.

What you may be noticing

Fatigue, brain fog, memory problems, mood changes, headaches, numbness or tingling, metallic taste, digestive complaints, or blood pressure changes. Perhaps you live in an older home, work with metals, eat a lot of large fish, drink well water, have older silver fillings, or had a childhood exposure. You may be wondering whether metals play a role in symptoms that have not responded to other care.

Acute poisoning, high blood lead in a child, or severe neurological symptoms need urgent medical care. Chelation therapy carries real risks and belongs only under qualified medical supervision.

Why it is rarely one thing

Heavy metals have no useful role in the body. They interfere with enzymes, bind to sulfur groups in proteins and glutathione, displace essential minerals such as zinc and calcium, generate oxidative stress, and impair mitochondrial function. Lead affects the brain and blood pressure. Mercury is neurotoxic. Arsenic and cadmium affect the kidneys, skin, and vessels.

Yet exposure alone does not predict symptoms. I think of the body as a toxic burden bucket that begins filling before birth, since metals and other chemicals cross the placenta. Metals share that bucket with mold, plastics, pesticides, and infections, and when it overflows, symptoms appear where you are most susceptible. Genetics shape how quickly you clear metals, yet a genetic variant shows susceptibility, not current burden. The question is not only what is in the bucket, but how well it is draining.

Patterns we look for

• Exposure history: home age, water source, occupation, diet, hobbies, and dental history, including amalgam fillings and root canals.
• Blood lead and whole blood metals for recent or ongoing exposure.
• Mineral status: zinc, selenium, iron, magnesium, and calcium.
• Glutathione, methylation capacity, and genetic variants linked to metal handling.
• Kidney, liver, bile, and bowel function, the main exit routes.
• Mitochondrial function and oxidative stress.
• Neurological signs: peripheral neuropathy, tremor, and cognitive changes.
• Total toxic burden, including mold and chemicals.

How I evaluate it

The comprehensive functional neurological exam assesses sensation, reflexes, tremor, coordination, eye movements, and cognitive function, revealing neurological effects.

Functional labs may include whole blood metals, blood lead, a comprehensive metabolic panel with kidney and liver function, zinc, copper, selenium, a complete blood count, homocysteine, and, in selected cases, genetic panels for detoxification. Test choice depends on exposure, and results are interpreted cautiously, because some commonly marketed tests are difficult to interpret.

How we address it

1. Identify and remove the source, which is always the first and highest-leverage step.
2. Open drainage pathways before mobilizing anything: daily bowel movements, hydration and urine flow, bile flow, lymph movement, and sweating.
3. Replenish protective minerals that compete with metals.
4. Support glutathione and antioxidant systems through cruciferous vegetables, colorful plants, and quality protein.
5. Address dental sources with a biological dentist trained in safe amalgam removal.
6. Coordinate any binding or chelation therapy with a qualified physician, only after drainage is flowing.
7. Support mitochondria, reduce neuroinflammation, and rebuild function with brain-based rehabilitation.

In children I am especially gentle: source control at home and school, a repeat blood lead with your pediatrician, and drainage and nervous system support rather than aggressive chelation. No level of lead in a child is known to be safe, so even small findings deserve attention.

This is resilience work, not fear. Testing your water, checking older paint and pipes, and choosing lower-mercury fish are simple starting points. Lighter burden, stronger drainage, and better-fed cells give the body room to recover.
