What is Resveratrol?

A polyphenolic compound found in grape skins, berries, and other plants. Resveratrol is studied for potential longevity and metabolic effects via sirtuins and other pathways. Classified as an antioxidant and anti-inflammatory compound.

How it works

Resveratrol activates sirtuins (SIRT1) and promotes NAD-dependent pathways associated with cellular energy and longevity. Also acts as direct antioxidant and anti-inflammatory compound.

Background & history

Gained modern attention from the French Paradox hypothesis (red wine and cardiovascular health). Extensive research began in 1990s-2000s on aging and metabolic pathways.

What the research says

Moderate animal evidence for longevity and metabolic benefits; human evidence limited. Small human studies show modest antioxidant effects and potential cardiovascular benefits. Evidence for brain or lifespan effects in humans remains preliminary.

Reported effects

Dosing & administration (informational)

Supplement doses typically 150-500 mg daily, though animal studies use much higher per-kg doses. No established human protocol; consult healthcare provider.

This is general research/context information, not medical advice or a recommended protocol.

Safety & side effects

Drug & supplement interactions

Who should avoid it

How it is commonly combined

Often combined with other polyphenols like quercetin or pterostilbene for synergistic antioxidant effects.

Quality & harm reduction

Lab testing & harm-reduction tools

If you are going to research a compound, verifying identity and purity is the single most protective step. Independent analytical testing and sterile-handling supplies reduce risk.

Frequently asked questions

Can I get resveratrol from wine?

Red wine contains resveratrol, but amounts are modest. Supplements deliver higher concentrated doses without alcohol.

Does it work for longevity in humans?

Animal evidence is encouraging. Human evidence remains preliminary. No proven lifespan extension in humans.

Should I cycle resveratrol or take it daily?

No established cycling protocol. Discuss frequency and duration with a healthcare provider.

Is resveratrol from Japanese knotweed better?

Both grape and Japanese knotweed sources are used; similar biochemical profiles, though knotweed concentrations can be higher.

Does resveratrol work without other compounds?

Resveratrol alone shows effects in studies; combination with other polyphenols may enhance action.
