How We Review the Research
Literature Search
We search PubMed for peer-reviewed randomized controlled trials, meta-analyses, and systematic reviews. Observational studies and animal research are excluded from our top evidence tier.
Evidence Ranking
Supplements are ranked by evidence strength: number of RCTs, sample size, replication of findings, and effect size — not by marketing spend or popularity.
Editorial Standards
Every guide requires a minimum of 5 PubMed citations. Dosages reflect clinically-studied ranges, and each recommendation carries an explicit evidence-strength label.
