Evidence-based supplement research
Which supplements actually work—and what does the research say about their risks?
Compare human evidence where available, safety concerns, and study-backed outcomes without the marketing hype. When the research cannot establish an answer, we say so.

Evidence stays visible
Human evidence, safety context, and uncertainty remain part of the answer.
Clinical outcomes stay separate from mechanisms, while interaction context and uncertainty remain visible instead of being flattened into a recommendation.

What these counts include: Published articles and herbs are public content or profile counts. Compounds tracked includes canonical research records that may not have a published profile. Structured studies counts deduplicated study/source records, not independently confirmed clinical trials. These populations differ from the indexable ingredient profiles counted in the evidence report.
Beyond the published evidence dataset, our source register tracks 7,435 unique PubMed references for further editorial review. Those are research-only identities, not an additional count of graded clinical studies. Explore the source trail →
