Resveratrol

Trans-resveratrol · Longevity

LimitedLittle human data — early, small, or narrow.

The molecule that launched the longevity supplement industry, and the one whose original science was retracted.

What the evidence says

Resveratrol built the field on sirtuin activation and the French-paradox story, and both have aged badly: direct SIRT1 activation was challenged as assay-dependent rather than real, and misconduct-related retractions affected part of the field (one researcher's papers, not the literature as a whole). Human trials in metabolic and cardiovascular endpoints are small and inconsistent, and bioavailability is genuinely poor. The field has largely moved on to NAD+ precursors, which is itself informative.

What studies used

Human trials have ranged widely, commonly 150–500 mg/day of trans-resveratrol. Poorly bioavailable; studies often paired it with fat.

Reported from published studies and product labelling — a record of what was used in research, not a recommendation. What is right for you is a conversation with a clinician.

Watch out for

  • Inhibits CYP enzymes and can affect clotting — relevant on anticoagulants
  • One trial in older men reported it BLUNTED the cardiovascular benefits of exercise training

Strong human evidence: either a phase 3 or 4 trial report alongside review-level evidence, or ten or more randomised controlled trial reports.
