Best Form

Resveratrol is a polyphenol compound found in red wine, grapes, and berries. It gained fame for potentially explaining the 'French Paradox' of low heart disease despite high fat intake. Research shows it activates sirtuins (longevity proteins) and has antioxidant effects. Human evidence is still emerging, with most studies in animals showing impressive results.

Mechanisms of Action

🧬
Sirtuin Activation

Activates longevity-associated proteins

🛡️
Antioxidant Effects

Neutralizes harmful free radicals

🔥
Anti-Inflammatory

Reduces inflammatory signaling

Recommended Dose

150-500mg trans-resveratrol

100mg1000mg

Optimal Timing

  • With a meal containing fat

Take with food

Best Form

Trans-resveratrol capsules

Alternatives: Micronized resveratrol, Liposomal

Trans-resveratrol is the active form. Look for products specifying trans-resveratrol content. Micronized forms may have better absorption.

Duration

Minimum: 4 weeks

Optimal: 12 weeks

Cycling: Not required

Note: Fat improves absorption. Some evidence suggests taking with quercetin may enhance effects. Bioavailability is generally low.

“Further high-quality, long-term studies are necessary to confirm these findings.© 2025 John Wiley & Sons Ltd.”
Key Findings:
  • We determined overall effect sizes using a random-effects model and assessed heterogeneity using the I 2 statistic and Cochrane's Q test.
  • This meta-analysis revealed significant reductions in body weight, BMI, and WC among T2D patients who consumed resveratrol.
  • However, we did not find any significant effects on HC or WHR.

“In conclusion, over the last 20 years, the increasing weight of clinical evidence suggests resveratrol can benefit human health, but more large, high-quality clinical trials are required to transition this intriguing compound from health food shops to the clinic.”
Key Findings:
  • Over the last 20 years, there have been almost 200 studies evaluating resveratrol across at least 24 indications, including cancer, menopause symptoms, diabetes, metabolic syndrome, and cardiovascular disease.
  • There are currently no consensus treatment regimens for any given condition or endpoint, beyond the fact that resveratrol is generally well-tolerated at a dose of up to 1 g/day.
  • Additionally, resveratrol consistently reduces inflammatory markers and improves aspects of a dysregulated metabolism.
  • In conclusion, over the last 20 years, the increasing weight of clinical evidence suggests resveratrol can benefit human health, but more large, high-quality clinical trials are required to transition this intriguing compound from health food shops to the clinic.

“The rankings of safety and efficacy of the 12 antioxidants vary.”
Key Findings:
  • The rankings of safety and efficacy of the 12 antioxidants vary.
  • Due to the low methodological quality of the included studies, the probability ranking cannot fully explain the clinical efficacy, and the results need to be interpreted with caution.
  • More high-quality studies are still needed to verify our findings.

“Further studies are now needed to better understand resveratrol's effects and define the optimal dosage and periods of intake to maximize beneficial effects, as well as to prevent adverse outcomes on implantation, subsequent pregnancy and the fetus.”
Key Findings:
  • The current literature, though limited, suggests that resveratrol may play a role in female infertility.
  • Specifically, it may significantly and positively impact reproductive outcomes, owing to its potential therapeutic effects improving ovarian function.
  • Further studies are now needed to better understand resveratrol's effects and define the optimal dosage and periods of intake to maximize beneficial effects, as well as to prevent adverse outcomes on implantation, subsequent pregnancy and the fetus.

“Dietary polyphenols may improve DAS28, reduce C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR), and improve oxidative stress, etc.”
Key Findings:
  • Dietary polyphenols may improve DAS28, reduce C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR), and improve oxidative stress, etc.
  • However, more RCTs are needed to verify or modify the efficacy and safety of dietary polyphenols.
  • Further research warranted to confirm findings
