Evidence Grading System

Every supplement claim on this site is graded on an A–D scale based on peer-reviewed clinical research from PubMed. Our algorithm evaluates study design (RCTs rank highest), consistency of results, sample sizes, and the overall body of evidence. No manufacturer sponsorship influences our grades.

A Strong Evidence

Multiple randomized controlled trials (RCTs) or meta-analyses with consistent positive results and large sample sizes.

B Good Evidence

At least one RCT with mostly consistent results across studies. Evidence suggests benefit but more research may be needed.

C Some Evidence

Small studies or observational data with some positive signals. Promising but insufficient for strong recommendations.

D Very Early Research

In vitro studies, case reports, or pilot studies only. Early-stage research that requires clinical validation.
