Heavy metals are not an exotic concern. They come from everyday sources, they accumulate over years, and they interfere with the same systems patients come to us about: energy, hormones, cognition and immune regulation.
Common exposure sources
- Lead - homes built before 1978, older plumbing, imported ceramics, some hobbies and shooting ranges.
- Mercury - large predatory fish, older dental amalgams, some industrial exposures.
- Arsenic - well water, rice and rice-based products, some poultry supply chains.
- Cadmium - cigarette smoke including secondhand, industrial exposure, some produce grown in contaminated soil.
- Aluminum - cookware, antiperspirants, certain antacids and processed food additives.
Who should consider screening
- Unexplained fatigue, brain fog or neuropathy with a clean standard workup.
- Autoimmune conditions that are not responding to a solid plan.
- Occupational exposure: construction, welding, dentistry, auto work, manufacturing, firing ranges.
- Well water as a primary drinking source.
- Fertility challenges or hormone patterns that resist correction.
How testing works
Blood measures recent exposure. Urine testing, particularly provoked testing when clinically appropriate, gives a better picture of stored body burden, since metals are sequestered in bone and tissue rather than circulating. We interpret results alongside mineral status, because metals displace essential minerals such as zinc, selenium and magnesium, and repleting those is part of the solution.
What a responsible protocol looks like
- Identify and remove the source. Detoxification while exposure continues is wasted effort.
- Open elimination pathways first: bowel, liver, kidney and lymphatic function.
- Replete displaced minerals and support glutathione production.
- Use binders and mobilization strategies carefully and in the right sequence, guided by retesting.
Aggressive detox protocols found online can mobilize metals faster than the body can clear them, which makes people feel considerably worse. Sequence and supervision matter here more than in almost any other area of functional wellness.
