The evidence in words

What it is

Resveratrol is a polyphenol from grapes and Japanese knotweed, famous for activating sirtuin longevity pathways in yeast and mice.

How it works

It was proposed to activate SIRT1 and mimic caloric restriction; in humans the effects are small, inconsistent, and complicated by poor bioavailability.

What the evidence shows

Despite enormous hype, human trials show at most trivial and inconsistent effects on metabolic and cardiovascular markers, and it can blunt some exercise adaptations. The animal-to-human translation simply did not hold. Safe but underwhelming.

How to use it

150–500 mg/day if trialing; expectations should be low.

Safety & interactions

Generally safe; mild antiplatelet effect and possible estrogenic activity at high doses. warfarin — Mild antiplatelet effect — additive bleeding risk.

Bottom line

The compound that started the longevity-supplement era and then disappointed. Human data are weak; spend elsewhere.

How it is used

As the entry records it, from the studies it summarises. Not a recommendation for you — doses that suit a trial population may not suit you.

If trialing
150–500 mg/day.
