Every rating linked to a peer-reviewed study

Know what your supplements are actually backed by.

Add your supplements, pick your goals, and see what each compound is proven to do, where the evidence is weak, and what overlaps. Every rating links to its source.

Example analysis

Creatine (monohydrate)

ATP regeneration (phosphocreatine)

Evidence by goal

  • Muscle & strengthA– Strong evidence
  • CognitionC– Weak evidence
  • LongevityC– Weak evidence

Supplement advice tells you what to take, rarely why.

Marketing over evidence

Trendy ingredients get shelf space, not the ones with data.

Hidden overlap

Different supplements often act on the same mechanism.

One-size claims

The same supplement isn't equally proven for every goal.

Our method

Sourced, not asserted

Every rating cites a real study, with a clickable link.

Human evidence first

Grades rest on human trials. Animal and lab studies give context, not a grade.

Per-goal evidence ratings

A compound can be well proven for one goal and weak for another.

Overlaps flagged

Redundant combinations are flagged, not ignored.

Independent, no marketing claims

No brand affiliations, no affiliate links, nothing sold.

A real rating from the database

Every claim traces to a study.

Resveratrol

Polyphenol, presumed SIRT1 activator (contested)

Example

Evidence by goal

  • LongevityD– Very weak / contested
  • Heart & metabolicB– Moderate evidence

Claimed vs proven

Claimed 'the anti-aging molecule from red wine' → proven: weak/inconsistent human signals, no lifespan extension even in the reference animal model. The most overhyped on this list.
