Resveratrol

📜 Historical Use

Resveratrol does not have a traditional-use history in the way a herb does, and the MSK monograph read for this page records none - it carries no traditional or historical use section at all. It is an isolated chemical rather than a plant preparation. MSK describes it as "a chemical found in grapes, red wine, peanuts, pistachios, blueberries, and cranberries," and lists among its food sources grape skins and seeds, peanuts, pistachios, mulberries, blueberries, cranberries, and Polygonum cuspidatum or Japanese knotweed. Japanese knotweed is the one item on that list with a long herbal history of its own, and the monograph refers to it elsewhere as "an herbal supplement rich in resveratrol." What this means in practice is that resveratrol reached the supplement shelf through food chemistry and the red-wine association rather than through any inherited pharmacopoeia, and the four uses the monograph lists as purported - preventing or treating heart disease, preventing or treating diabetes, improving memory, and relieving joint pain due to osteoarthritis - read as a modern marketing list rather than an inherited one.

📊 What the Research Shows

The clinical record is mostly negative, and it is negative on exactly the uses resveratrol is sold for. On cardiovascular health, earlier studies showed reduced LDL oxidation and platelet aggregation, but MSK reports that "a meta-analysis did not find benefit with resveratrol supplementation on cardiovascular risk factors" and that "it does not decrease risk of all-cause mortality in older adults." On blood sugar, "studies on resveratrol for diabetic patients are mixed" and "a Cochrane review determined there is currently insufficient evidence for its use in diabetes." On cognition, "a meta-analysis did not find any significant effect on memory or cognitive performance." Those three findings cover heart disease, diabetes and memory, which are three of the four uses the monograph itself lists as purported. The fourth, relieving joint pain due to osteoarthritis, appears in that purported-uses list without a supporting trial result reported alongside it. Cancer data are described as quite limited, with one colorectal study suggesting tumour reduction and another suggesting any utility is confined to prevention. Read together, this is a compound with a plausible laboratory profile and an unconvincing human one. Anyone taking resveratrol for heart health, blood sugar or memory should know that the pooled evidence for all three has come back null, and that the absence of benefit was found in meta-analysis rather than in one disappointing study.

Take 200-500mg trans-resveratrol daily with a fatty meal. Combine with NMN for sirtuin activation.

May interact with blood thinners. Quality varies hugely — use trans-resveratrol form only.

⚠️ What happens if taken in excess:

Very high doses (>5g/day) can cause nausea, vomiting, diarrhea, and liver dysfunction. May enhance blood-thinning effects. Can cause estrogenic effects and is concerning for hormone-sensitive cancers. May interact with CYP enzymes affecting medication metabolism. Quality varies hugely between products.

Resveratrol is an enzyme-level interactor, which makes it a more plausible source of real-world drug problems than its weak efficacy record would suggest. MSK reports that it inhibits CYP3A4, CYP2D6 and CYP2C9, and induces CYP1A2. Between them those enzymes handle a large share of prescription drugs, so inhibition can raise circulating levels of a co-administered drug while induction of CYP1A2 can lower them. Carbamazepine is named specifically, affected through CYP3A inhibition and through transporter effects. The second named interaction is bleeding: because resveratrol inhibits platelet aggregation, MSK flags a risk of increased bleeding when it is combined with antiplatelet medication. The precision there is deliberate and worth preserving. The monograph names antiplatelets, and this entry does not extend that to anticoagulants such as warfarin without a source that says so, even though the live page currently uses the looser phrase "blood thinners". Anyone taking an antiplatelet drug, taking carbamazepine, or taking any narrow-therapeutic-index drug cleared by CYP3A4, CYP2D6, CYP2C9 or CYP1A2 should treat resveratrol as a drug-interaction question rather than a supplement question.
