Supplements
Do supplements (creatine, magnesium, collagen, mushroom, herbal) contain heavy metals?
This corpus does not contain verified metal concentrations for creatine, magnesium, collagen, mushroom, or herbal supplements. A calcium-supplement paper is named in the draft notes and was not saved here, so its values are not repeated. No brand is named.
What is not available
No concentration for these product types was verified. Clay and mineral supplements are in the same gap.
Related evidence, where it exists, is on the linked pages. Those pages do not fill this gap.

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.
