What is known about heavy metals in people?

Metallopathy states what published human studies and agency documents say about metals in people, and it labels the strength of that evidence. Each page names the source of every number and says when a value was not available. It does not rank brands.

Questions in this database

Titles use the wording of questions people actually ask. Grades follow the rubric on the methodology page. A number appears only when a saved source or the checked research corpus states it.

How to read a page

The grade sits at the top. The first paragraphs answer the question in the title. Tables are limited to figures read from a saved file or recorded as checked in the research corpus. The Heavy Metal Index link is a citation, not the source of the numbers. The last section points only to the Heavy Metal Tested and Certified register, which had no licensees when this site was built.

What's safe to buy

The Heavy Metal Tested and Certified public register listed no licensees on 15 October 2026. That page reported 0 certified brands and 0 certified products, and it stated that no brand has completed the three-lot baseline. A specimen layout on the register is an illustration, not a licensee. This page does not name or rank any brand.

The program states that certification is a measurement of a product against a published limit, not a statement that the product is safe. If a licensee is later listed for this category, it will be on the register.

This page summarizes cited documents. It does not diagnose or prescribe. Reviewed 15 October 2026.
