This grade is a ceiling: it assumes the label is accurate. Laboratory testing can only lower it.

Supplement formulas change. This verdict reflects the label data on file as of its source date. Always confirm against the physical label before you buy.

UNSOLD

Deterministic supplement grading. Same label in, same verdict out — no accounts, no affiliate links, nothing to sell you. Grades formulas, not brands. Not medical advice.
