Heavy Metal Toxicity

Gabriel explains heavy metal testing and results in plain words, starting with the test that fits your exposure: a blood lead level for lead, and a 24-hour urine or whole-blood test for mercury. Provoked urine testing, where a chelating drug is taken first, is not validated: the American College of Medical Toxicology says it has no demonstrated benefit and may be harmful. The approach, tiered by evidence: 1) Find and remove the source (strongest evidence, always first: old paint and dust, water, work, hobbies, fish, supplements, imported spices or remedies), 2) Confirm with a validated test, 3) Prescription chelation (such as DMSA by mouth, or CaNa2EDTA by IV for severe lead poisoning) only for confirmed, significant poisoning and only under a licensed clinician, usually a medical toxicologist, with labs before, during and after; it can lower blood calcium and harm the kidneys, the FDA warns chelation can cause dehydration, kidney failure and death, and no over-the-counter chelation product is FDA-approved, 4) Nutrition (enough calcium, iron, protein and fiber; CDC asks clinicians to review calcium and iron in children with raised lead), 5) Binders many integrative practitioners use, such as chlorella or modified citrus pectin (weak human evidence; choose third-party tested products, since some carry metals), 6) Support the liver, kidneys and bowel with food, fluids, movement and sleep. Amalgam fillings: the FDA does not recommend removing fillings in good condition unless medically necessary.
