HelloPharmacist Scorecard of 2 Phase-Zyme by Douglas Laboratories
Four independent checks of what is known — a summary of the available information, not a grade of the product itself.
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed

Why this rating?
