Symptoms
Can heavy metals cause brain fog / depersonalization?
No study in this corpus tested brain fog or depersonalization as an outcome of metal exposure or of a detox protocol. Neurodevelopmental endpoints for lead and methylmercury are different outcomes and are described on those metal pages. They are not a finding about brain fog.
Nearby evidence that is a different question
The TLC trial found no cognitive benefit from succimer in children with blood lead of 20 to 44 µg/dL. That is a null cognitive result at those levels, not a study of brain fog in adults. Rogan 2001.

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.
