3,5,4'-trihydroxy-trans-stilbene, grape polyphenol · Evidence-based safety and harm-reduction overview.
| Also known as | 3,5,4'-trihydroxy-trans-stilbene, grape polyphenol |
| Category | Supplement |
| native_region | Grapes (worldwide), Japanese knotweed (Asia) |
| active_compounds | Resveratrol (trans-isomer), pterostilbene, other polyphenols |
| US legal status | Resveratrol is a lawful dietary supplement under DSHEA. Not FDA-approved for medical use but derived from plant sources like grapes and Japanese knotweed. |
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.
Resveratrol activates sirtuins (SIRT1) and promotes NAD-dependent pathways associated with cellular energy and longevity. Also acts as direct antioxidant and anti-inflammatory compound.
Gained modern attention from the French Paradox hypothesis (red wine and cardiovascular health). Extensive research began in 1990s-2000s on aging and metabolic pathways.
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.
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.
Often combined with other polyphenols like quercetin or pterostilbene for synergistic antioxidant effects.
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.
Compare testing optionsRed wine contains resveratrol, but amounts are modest. Supplements deliver higher concentrated doses without alcohol.
Animal evidence is encouraging. Human evidence remains preliminary. No proven lifespan extension in humans.
No established cycling protocol. Discuss frequency and duration with a healthcare provider.
Both grape and Japanese knotweed sources are used; similar biochemical profiles, though knotweed concentrations can be higher.
Resveratrol alone shows effects in studies; combination with other polyphenols may enhance action.
