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 grades formulas, not brands — and we're not doctors. This is information, not medical advice; check with a qualified healthcare professional before changing what you take.

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.
