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.
Multiple randomized controlled trials (RCTs) or meta-analyses with consistent positive results and large sample sizes.
At least one RCT with mostly consistent results across studies. Evidence suggests benefit but more research may be needed.
Small studies or observational data with some positive signals. Promising but insufficient for strong recommendations.
In vitro studies, case reports, or pilot studies only. Early-stage research that requires clinical validation.
