Supplement: Resvératrol

My Plan

Le resvératrol est un composé présent dans le vin rouge, le raisin et les cacahuètes, et il est devenu célèbre pour une allégation : qu'il active les enzymes sirtuines, imite la restriction calorique et ralentit le vieillissement. Cette allégation a prolongé la vie chez la levure et amélioré la survie chez des souris nourries d'un régime engraissant. Chez l'humain, elle n'a pas tenu.

Le resvératrol alimentaire n'a montré aucun lien avec une vie plus longue au cours d'une étude de neuf ans sur des personnes âgées. Ce qui tient est plus étroit : une meilleure glycémie chez les personnes diabétiques, une tension artérielle systolique plus basse à fortes doses, et un long historique de bonne tolérance. Un verre de vin rouge en contient bien trop peu pour compter.

Findings & Outcomes

What It Is

Resveratrol is a compound that grapevines and a few other plants make when injured or attacked by fungus. It belongs to the stilbene family of plant polyphenols and turns up in grape skins, red wine, peanuts, and some berries, usually in small amounts.

Most people first met resveratrol through the French paradox, a term popularized in 1992: some wine-drinking populations had less heart disease than their rich diets predicted. Supplement makers then sold it on the promise of slower aging.

Anatomy of the Practice

1In the test tube and the cell

Resveratrol does many things to cells in a dish: it influences the sirtuin enzymes, dampens some inflammatory signals, and acts as an antioxidant. These are the effects the reputation was built on, and they hold up in the test tube. They are only a starting point.

2On the way through the gut and liver

Swallowed resveratrol is absorbed well, but the gut wall and liver chemically alter most of it within the first pass. Very little reaches the bloodstream as the original molecule, so a capsule delivers less active compound than the amount absorbed suggests.

3Where measured effects do turn up

Despite the low blood levels, human trials do register real changes, but almost always in people who started with something to correct: high blood sugar, or high blood pressure. In people who were already healthy, little moved. These effects are specific to those groups, not the whole-body anti-aging benefit once advertised.

How It Works

The sirtuins, a family of enzymes, help regulate metabolism and the stress response inside cells. In 2003 a laboratory study reported that resveratrol activates SIRT1 and extends the lifespan of yeast. Later work in the same line reported longer life in worms, flies, and fish. The pitch was simple. Calorie restriction reliably extends life in many animals, partly through sirtuins, and here was a wine molecule that seemed to copy the effect without the diet. That idea launched the supplements and the popular science books.

The mechanism did not hold up. A 2010 study found that resveratrol did not directly activate SIRT1 once a fluorescent tag was removed from the test peptide. The original activation looks partly like an artifact of how the enzyme was measured. Researchers still debate how resveratrol affects sirtuins, and it clearly shifts cell metabolism. The confident claim that it directly activates a sirtuin has weakened, and that was the one clean mechanism the anti-aging case rested on.

Bioavailability is the deeper problem. When six volunteers took a 25 mg oral dose of labeled resveratrol, at least 70% was absorbed. Yet the unchanged resveratrol left in the blood was a trace, under 5 ng/mL, because conjugation happens within minutes. The concentrations that act on cells in a dish are hard to reach in living tissue from a capsule. Some conjugates may be active, and resveratrol may collect in the gut lining, so the question stays open. This gap is why a striking cell or animal result shrinks in a person.

What Changed

For a stretch of the 2000s resveratrol was the most discussed molecule in aging research, on the strength of the mouse work. In 2006 a study found that resveratrol improved the survival of middle-aged mice fed a high-calorie diet. It shifted their physiology toward that of mice on a standard diet. Press coverage compressed this into a longevity pill. Sirtris, a company built on sirtuin activators, was bought by GlaxoSmithKline for about $720 million in 2008, and the claim stuck.

The correction came from the same field. A 2008 study by many of the same researchers gave resveratrol to mice on a normal diet. It copied some gene-expression patterns of calorie restriction and improved several health markers, yet lifespan did not rise. The survival benefit came from offsetting the bad diet; a healthy mouse on a normal diet gained no extra lifespan. Human trials that followed were mostly small, ran for weeks to months, and disagreed on the main outcomes. No human trial has shown that resveratrol extends life. Then researchers measured resveratrol intake against lifespan directly. In 783 community-dwelling adults aged 65 and over, followed for nine years, they found no link to death, heart disease, cancer, or inflammation. Longevity is the claim that made resveratrol famous, and the human data do not support it.

Away from the aging claim, a smaller, steadier set of effects holds. Pooled human trials, in a meta-analysis of 11, point to metabolic effects in people with diabetes: better fasting glucose, insulin, HbA1c, and insulin resistance. In people whose glucose was already normal, little moved. Type 2 diabetes makes up 90–95% of diabetes cases and is largely diet-driven, much of it from ultra-processed food built around sugar, fat, and salt. Resveratrol, where it helps at all, is a minor lever downstream of that cause. A separate pooled analysis found that doses of 150 mg a day and above lowered systolic blood pressure, while the diastolic number did not move. These are modest, group-specific effects on small evidence bases, and they are the effects resveratrol has support for.

The longevity claim that made resveratrol famous is the one the human data do not support.

How it works

Le resvératrol n'a pas activé directement SIRT1 une fois le marqueur fluorescent retiréModerate · mixed
In plain terms

The idea that resveratrol switches on the sirtuin longevity enzymes was the heart of its reputation, but a later lab study could not reproduce that switch without a fluorescent tag on the test, so the direct-activation claim is now in doubt.

In detail

L'histoire des sirtuines a commencé avec Howitz et al. 2003 (Nature), qui rapportait que le resvératrol active SIRT1 et prolonge la durée de vie réplicative chez Saccharomyces cerevisiae. Pacholec et al. 2010 (J Biol Chem) ont montré que le resvératrol et plusieurs candidats activateurs synthétiques n'activaient pas SIRT1 contre des substrats peptidiques natifs, et que l'activation apparente dépendait d'un fluorophore non physiologique (7-amino-4-méthylcoumarine) fixé au peptide de l'essai. Le resvératrol affecte toujours le métabolisme cellulaire par des voies débattues, mais l'affirmation spécifique d'une activation directe de SIRT1 n'est pas tranchée.

Environ 70 % d'une dose orale est absorbé, mais moins de 5 ng/mL reste dans le sang sous forme de resvératrolModerate · mixed
In plain terms

Votre corps absorbe la majeure partie du resvératrol que vous avalez, mais l'intestin et le foie en convertissent presque la totalité en quelques minutes, si bien que presque aucune molécule active n'atteint le sang. Les niveaux qui agissent sur les cellules en boîte de culture sont difficiles à atteindre en prenant une gélule.

In detail

Walle et al. 2004 (Drug Metab Dispos) ont administré à six volontaires humains 25 mg de resvératrol marqué au 14C, par voie orale et intraveineuse. L'absorption était d'au moins 70 %, le pic plasmatique de resvératrol plus métabolites a atteint environ 2 micromolaires, mais le resvératrol parent inchangé était inférieur à 5 ng/mL. La conjugaison rapide en sulfate par l'intestin et le foie était l'étape limitante. Les auteurs ont noté que les conjugués ou une accumulation dans l'épithélium aérodigestif pourraient tout de même avoir des effets, de sorte que de faibles taux plasmatiques du composé parent n'excluent pas à eux seuls toute activité.

Longevity And Mortality

Le resvératrol alimentaire n'a montré aucun lien avec le décès, la maladie cardiaque ou le cancer chez 783 adultes plus âgés sur neuf ansModerate · no effect
In plain terms

Chez des adultes plus âgés suivis pendant neuf ans, la quantité de resvératrol tirée de l'alimentation n'a montré aucun lien avec la durée de vie ni avec les taux de maladie cardiaque, de cancer ou d'inflammation.

In detail

Semba et al. 2014 (JAMA Intern Med), issue de la cohorte InCHIANTI, ont mesuré les métabolites urinaires du resvératrol chez 783 adultes âgés de 65 ans ou plus. Sur neuf ans, 268 (34.3 %) sont décédés, sans gradient significatif entre les quartiles de métabolites du resvératrol (P = 0.67) et sans association avec les marqueurs inflammatoires, la maladie cardiovasculaire prévalente ou incidente, ou le cancer. L'exposition reflète le resvératrol alimentaire (aliments et vin), très inférieur aux doses de complément.

Le resvératrol a amélioré la survie de souris d'âge moyen suivant un régime hypercaloriquePreliminary
In plain terms

Des souris nourries avec un régime engraissant ont vécu mieux et plus longtemps lorsqu'elles recevaient du resvératrol, et leur corps ressemblait davantage à celui de souris suivant un régime normal. Il s'agit d'un résultat animal obtenu sous un régime spécifique, non démontré chez l'humain.

In detail

Baur et al. 2006 (Nature) ont nourri des souris d'âge moyen avec un régime hypercalorique, avec ou sans resvératrol. Le resvératrol a augmenté la survie et la sensibilité à l'insuline, amélioré la fonction motrice, et produit des changements organiques et d'expression génique recoupant ceux de la restriction calorique. Le bénéfice a été démontré dans le contexte d'un régime hypercalorique, et non chez des animaux sains normalement nourris.

Le resvératrol n'a pas prolongé la durée de vie de souris sous régime standardPreliminary · no effect
In plain terms

Lorsque les souris suivaient un régime normal, non engraissant, le resvératrol a amélioré certains marqueurs de santé mais ne les a pas fait vivre plus longtemps. Le bénéfice de survie observé précédemment était lié au mauvais régime, pas au vieillissement lui-même.

In detail

Pearson et al. 2008 (Cell Metab) ont rapporté que le resvératrol induisait dans plusieurs tissus des schémas transcriptionnels parallèles à ceux de la restriction calorique et du jeûne un jour sur deux, et améliorait plusieurs mesures de santé chez des souris sous régime standard, mais n'augmentait pas la durée de vie. Bon nombre des mêmes chercheurs avaient participé à l'étude de survie sous régime hypercalorique de 2006, ce qui fait de l'absence d'effet sur la durée de vie chez les souris normalement nourries une qualification directe de ce résultat antérieur.

Blood Sugar

Le resvératrol a amélioré le contrôle de la glycémie chez les personnes diabétiques dans 11 essais, sans effet chez celles qui ne le sont pasModerate
In plain terms

Chez les personnes diabétiques, la prise de resvératrol a modestement amélioré le contrôle de la glycémie et la résistance à l'insuline. Chez les personnes dont la glycémie était déjà normale, elle n'a fait aucune différence mesurable.

In detail

Liu K et al. 2014 (Am J Clin Nutr) ont regroupé 11 essais contrôlés randomisés totalisant 388 sujets. Chez les participants diabétiques, le resvératrol a significativement réduit la glycémie à jeun, l'insuline, l'HbA1c et le HOMA-IR. Chez les participants non diabétiques, il n'y avait aucun effet significatif, et les analyses de sous-groupes et de méta-régression dans ce groupe n'étaient pas affectées par l'IMC, la dose, la durée ou la qualité de l'étude. Les essais étaient de petite taille et hétérogènes en termes de dose et de durée.

75 mg par jour pendant 12 semaines n'a modifié aucune mesure métabolique chez des femmes ménopausées non obèsesModerate · no effect
In plain terms

Chez des femmes ménopausées métaboliquement en bonne santé, trois mois de resvératrol ont augmenté son taux sanguin mais n'ont rien changé de mesurable dans leur métabolisme.

In detail

Yoshino et al. 2012 (Cell Metab) ont mené un essai randomisé, en double aveugle, contrôlé contre placebo, de 75 mg/jour de resvératrol pendant 12 semaines chez des femmes ménopausées non obèses présentant une tolérance normale au glucose. Malgré une hausse du resvératrol plasmatique, aucun changement n'a été observé dans la sensibilité à l'insuline, la composition corporelle, le taux métabolique de repos, les lipides plasmatiques ou les marqueurs inflammatoires. C'est le pendant du bénéfice observé chez les diabétiques : là où il n'y a pas de problème métabolique à corriger, l'essai n'a trouvé aucun changement.

Who this may not transfer to:Tested only in nonobese postmenopausal women; the null result fits the wider pattern that resveratrol moves metabolic measures mainly in people who already have a metabolic problem, so a similar lack of effect in metabolically healthy men is plausible but untested.

In plain terms

Le resvératrol n'a pas fait baisser la tension artérielle en moyenne, mais à des doses plus élevées de 150 mg par jour et plus, il a réduit le chiffre supérieur. Le chiffre inférieur n'a pas bougé.

In detail

Liu Y et al. 2015 (Clin Nutr) ont regroupé six essais contrôlés randomisés totalisant 247 sujets. L'effet global sur la pression systolique et diastolique n'était pas significatif. Un sous-groupe pré-spécifié prenant 150 mg/jour ou plus a montré une réduction systolique significative de -11.90 mmHg, bien que l'intervalle de confiance ait été large (-20.99 à -2.81), tandis que la méta-régression n'a pas confirmé un effet dose-continu. La pression diastolique n'a pas été affectée.

Ways to Do It

Match what you do to what the evidence supports. For longevity that is little; for metabolic markers in specific groups it is narrow but present.

1
Eat the foods it comes inFreeEasy

Grapes, blueberries, peanuts and dark chocolate carry small amounts of resveratrol as part of whole foods that already belong in a good diet. Get trace amounts from a varied diet and expect nothing dramatic from them.

2
A basic trans-resveratrol powder, for a specific metabolic target$Easy

If your aim is blood sugar and you have diabetes, plain trans-resveratrol is the studied form. Human trials ran from roughly 150 mg to 1000 mg a day, sometimes higher. Buy the trans form from a supplier carrying an independent testing mark. Make this decision with the doctor managing your diabetes, adding it to your existing treatment.

3
A higher dose aimed at blood pressure, with a clinician$ to $$Easy

For blood pressure, the studied doses start around 150 mg a day. If that is the goal, raise it with the prescriber following your readings, and weigh it against the blood-thinner interaction in the cautions.

4
A plain third-party-tested product$Easy

Resveratrol is a commodity. A third-party testing mark, NSF or Informed Choice, confirms the capsule holds what the label says. No advanced form has been shown to solve the bioavailability problem in people, so the testing mark is the thing to check.

5
Do the free basics with the strongest human evidenceFreeModerate

For the healthy aging the supplement is marketed on, the measures with solid human evidence are exercise, sleep, not smoking, and a diet built on whole foods. If the goal is to age well, do these first.

Go Deeper

  • Taurine: made famous by its own 2023 aging study: like resveratrol, a strong animal result but thin human data.
  • Omega-3 and fish oil: heart claims tested against hard clinical outcomes in large human trials.

The Chinese Medicine View

Resveratrol was first isolated and named in the 1900s, so it has no place in the classical Chinese pharmacopoeia. No historical text gives it a channel, a temperature, or a flavor. The tradition speaks instead about the foods it occurs in. Grapes read as sweet and sour and roughly neutral, tonifying to Qi and Blood and to the Liver and Kidney, a nourishing everyday fruit.

Wine reads very differently. It is warm and acrid, moving Qi and Blood, and it can free a stagnant, cold pattern in small amounts. Taken regularly it breeds internal heat and damp, burdening the Spleen and clouding the Liver, so the tradition would not prescribe wine for the heart. The same logic goes further: a warming, moving substance that helps one person can aggravate another, so the tradition would not give everyone the same dose. That individualized-dosing logic sits oddly next to a modern finding: resveratrol lowered blood sugar mainly in people whose sugar was already high. The two ideas rhyme, but the tradition was reasoning about heat and constitution, not blood glucose, so the modern result does not vindicate the old logic.

Cautions For This Practice

Extra restraint

Everything to be aware of is here, in one place. This practice suits most healthy people; a few situations call for real care.

Des doses de l'ordre du gramme, de 2.5 à 5 g par jour, ont provoqué des nausées et des selles molles chez de nombreuses personnes

Les revues sur la sécurité du resvératrol (Shaito et al. 2020, Int J Mol Sci) résument que les doses faibles à modérées sont généralement bien tolérées, tandis que les doses de l'ordre du gramme produisent des symptômes gastro-intestinaux liés à la dose. Dans Brown et al. 2010 (Cancer Res), 40 volontaires en bonne santé ont pris de 0.5 à 5 g/jour pendant 29 jours ; les doses plus élevées ont produit des plaintes gastro-intestinales et réduit l'IGF-1 et l'IGFBP-3 circulants, un effet de signification clinique incertaine.Shaito et al. 2020, Int J Mol Sci (potential adverse effects of resveratrol)Brown et al. 2010, Cancer Res (repeat-dose safety in healthy volunteers)

Le resvératrol peut s'ajouter à l'effet des anticoagulants et ralentir les enzymes hépatiques qui éliminent de nombreux médicaments

Des revues de sécurité (Shaito et al. 2020, Int J Mol Sci) rapportent que le resvératrol inhibe plusieurs enzymes du cytochrome P450, dont CYP3A4, CYP2C9, CYP2D6 et CYP1A2, qui métabolisent une grande part des médicaments sur ordonnance, et qu'il exerce des effets antiplaquettaires. La majeure partie de ces preuves est in vitro ; les études d'interaction clinique chez l'humain sont limitées, de sorte que la préoccupation pratique est potentielle et mal quantifiée, ce qui plaide pour un examen par un clinicien ou un pharmacien.Shaito et al. 2020, Int J Mol Sci (adverse effects and drug interactions review)

Blood thinners, antiplatelet drugs and surgery

Resveratrol has antiplatelet activity, so it can add to the effect of a blood thinner such as warfarin, aspirin, or clopidogrel. At high doses it can also inhibit several liver enzymes that clear common drugs. That may raise the blood levels of medicines those enzymes process. If you take a blood thinner, or you have surgery coming up, tell your prescriber before adding resveratrol, and ask about pausing it beforehand.

Drugs cleared by the liver enzymes it affects

In laboratory work resveratrol inhibits cytochrome P450 enzymes such as CYP3A4 and CYP2C9. Between them these handle a large share of prescription drugs. Most of this evidence is from the test tube, with few measured interactions in people. Still, if you take regular medication, raise resveratrol with your pharmacist. A plant compound can still interfere.

High doses can upset the stomach

At 2.5 to 5 grams a day, the doses in some cancer-prevention studies, resveratrol caused mild to moderate nausea, loose stools, and abdominal discomfort. High doses also lowered a growth-factor hormone called IGF-1, an effect of uncertain meaning. These gram-level doses bring stomach effects without added benefit, and the studied metabolic doses are far lower.

Pregnancy, breastfeeding and hormone-sensitive conditions

Supplemental resveratrol has not been well studied in pregnancy or breastfeeding, so food-level intake is the sensible ceiling there. Resveratrol can also have weak estrogen-like activity in some tissues. Anyone with a hormone-sensitive condition should check with their doctor before taking a supplement dose, and keep to food-level amounts otherwise.

Anti-aging use

Using resveratrol to slow your own aging is experimental. There is no established anti-aging dose, and long-term supplement-level use has not been tested for safety.

Start slow, be smart, read the research, and consult a professional if you have any concerns. This is here to inform your choice, not make it for you.

Common Questions

Does resveratrol actually help you live longer?

The deciding study has not been done. No one has run a long randomized trial that doses people and follows how long they live. Until that trial reports, the answer rests on animal data alone.

Should I look for trans-resveratrol specifically?

Yes. Trans-resveratrol is the stable form used in nearly every human trial, so it is the one that matches the evidence. The cis form is less stable and barely studied.
