Check supplement claims against the evidence.
Evidence Stack is a free supplement research library. We summarize study quality, practical use cases, caveats, and source links so readers can understand what a claim is actually supported by.
Source linked
Verdicts point back to evidence.
Claim specific
Scores answer the stated use case.
Evidence preview
160 reviews
912 linked sources. Scores answer the claim, not the hype.
Example review types
Clear verdicts without sales pressure
These examples show the format of the library: a claim, an evidence score, a brief finding, and caveats that keep the verdict practical.
Creatine monohydrate
Strong evidence for strength-related outcomes and lean-mass support when training is in place.
Protein powder
Useful when it helps someone reach a daily protein target; redundant when intake is already adequate.
Beta-alanine
Best supported for repeated high-intensity efforts lasting roughly one to four minutes.
Psyllium husk
Strongest case is soluble-fiber support for LDL cholesterol and regularity, with dose and tolerance context.
Methodology
How Evidence Stack avoids hype
Evidence hierarchy
Systematic reviews, meta-analyses, society position stands, and randomized trials carry the most weight.
Claim-level ratings
A score applies to a specific use case. We do not turn indirect markers into broad promises.
Transparent caveats
Dose, form, study population, quality control, and safety context are shown alongside the score.
Commercial restraint
Product links appear only for selected evidence-matched picks and do not influence ratings.
