Feature Summary

Resveratrol is a natural polyphenol found in many plants, especially grapes and peanuts. It is widely recognized as a potent antioxidant with multiple actions that promote cellular longevity and health. Resveratrol provides protection against oxidative stress both via direct antioxidant effects and by activating cellular pathways associated with antioxidant defence. This includes stimulation of the potent transcription factor, nuclear erythroid 2-related factor 2 (Nrf2), which increases the expression of multiple antioxidant enzymes associated with cardioprotective, neuroprotective, and healthy aging effects.1–3

Resveratrol also activates the sirtuin SIRT1, a protein responsible for regulating many essential cellular functions, including DNA repair, mitochondrial biogenesis, autophagy, inflammation, metabolism, and more. SIRT1 has been associated with healthspan, longevity, cardiovascular function, and reduced risk for many age-related conditions.4–6 Indeed, SIRT1 is considered a “longevity gene,” as many of the longevity benefits of calorie restriction observed in experimental studies are thought to be mediated through SIRT1 activation.7–10 Clinical trials with resveratrol have demonstrated several aging-related benefits, including increased SIRT1 levels, enhanced cognitive function, and improved cardiovascular risk factors.11–14

Extracted from the skin of red grapes grown in the Okanagan Valley of British Columbia and from Japanese knotweed, this formula provides 100% trans-resveratrol, which is more bioavailable and stable than cis-resveratrol.15,16

Drug Interactions

Resveratrol is considered a weak inhibitor of CYP3A4/5 and CYP2E1, and may increase the plasma concentration of drugs metabolized by these enzymes, such as triazolam and carbamazepine.17–19
