Resveratrol
Le resveratrol est un polyphenol stilbene produit naturellement par certaines plantes (raisin, vin rouge, mures, arachides) en réponse au stress ou aux infections fongiques. Il active les sirtuines (notamment SIRT1), des proteines impliquees dans la longevite cellulaire et la regulation metabolique, ce qui justifie son reputation de molecule anti-vieillissement. Des propriêtes anti-inflammatoires, cardioprotectrices, neuroprotectrices et anticancereuses ont ete documentees in vitro et dans des modeles animaux, avec des preuves humaines plus limitees mais prometteuses.
Resveratrol
Resveratrol is a naturally occurring stilbene polyphenol produced by plants such as grapes, red wine, mulberries, and peanuts under stress. It activates sirtuins (particularly SIRT1), proteins involved in cellular longevity and metabolic regulation, underpinning its reputation as an anti-aging molecule. Anti-inflammatory, cardioprotective, neuroprotective, and anticancer properties are well documented in preclinical studies, with emerging human evidence. Bioavailability is low due to rapid metabolism, which limits clinical translation.
Resveratrol
El resveratrol es un polifenol estilbeno producido naturalmente por plantas como la uva, el vino tinto y el mani bajo condiciones de estres. Activa las sirtuinas (SIRT1), proteinas implicadas en la longevidad celular y la regulacion metabolica. Sus propiedades antiinflamatorias, cardioprotectoras y neuroprotectoras estan bien documentadas en estudios preclinicos, aunque la evidencia humana es mas limitada.

Interactions et precautions
Interactions and precautions
Interacciones y precauciones
- Anticoagulants/antiplatelets (warfarin, aspirin, clopidogrel): resveratrol inhibits platelet aggregation — increased bleeding risk
- CYP450 enzymes: inhibits CYP3A4, 2D6, 2C9; induces 1A2 — may alter metabolism of many medications including statins, certain antidepressants, and immunosuppressants
- Hormone-sensitive conditions: resveratrol has estrogenic properties — caution with estrogen-sensitive cancers or hormone therapy
Des doses elevees peuvent provoquer des troubles gastro-intestinaux. Interactions medicamenteuses significatives via les enzymes CYP450 — toujours signaler à un medecin en cas de prise de medicaments. Propriêtes estrogeno-mimetiques: deconseille aux patients avec antecedents de cancers hormono-dependants. Ne pas utiliser pendant la grossesse (sources de resveratrol incluant le vin doivent être evitees). La biodisponibilite est faible, ce qui limite les effets cliniques aux doses standard des suppléments.
High doses may cause GI discomfort. Significant drug interactions via CYP450 enzymes — always inform a physician if on medications. Estrogen-mimetic properties: not recommended for patients with hormone-sensitive cancer history. Do not use during pregnancy. Low bioavailability limits clinical effects at standard supplément doses.
Dosis altas pueden causar molestias gastrointestinales. Interacciones medicamentosas significativas via enzimas CYP450. Propiedades estrogeno-mimeticas: no recomendado en pacientes con antecedentes de cancer hormono-dependiente. No usar durante el embarazo.
