Resveratrol supplement with a hydrogel coating designed to boost bioavailability up to 10x compared to unformulated resveratrol. Each vegetarian capsule delivers trans-resveratrol from Japanese knotweed plus quercetin, a phytonutrient that supports cardiovascular and immune health.

Resveratrol shows robust mechanistic plausibility and longevity effects in animal models, but human trials remain sparse and inconsistent. Observational studies suggest associations with cardiovascular and metabolic benefit, yet the strongest RCTs (including CALERIE-related work and cardiovascular endpoints) have not consistently replicated anti-aging or mortality reduction in humans. Bioavailability is a major constraint—standard oral doses achieve only modest plasma concentrations.
Resveratrol is a polyphenol found in grapes and berries that activates sirtuins (NAD+-dependent deacetylases) and AMPK (adenosine monophosphate-activated protein kinase), pathways implicated in longevity, mitochondrial function, and metabolic health. It may also reduce oxidative stress and inflammation.

“Cardiovascular diseases (CVD), especially coronary artery disease (CAD), are among the most important causes of mortality in the world.”
“IMPORTANCE: Resveratrol, a polyphenol found in grapes, red wine, chocolate, and certain berries and roots, is considered to have antioxidant, anti-inflammatory, and anticancer effects in humans and is related to longevity in some lower orga”
“In the past decade, the small polyphenol resveratrol has received widespread attention as either a potential therapy or as a preventive agent for numerous diseases.”
Most evidence for life-extension and sirtuin activation comes from animal studies (C. elegans, rodents) at doses not easily translatable to humans. Few rigorous RCTs in humans exist; available trials are mostly short-term and underpowered. Resveratrol's bioavailability is poor (typically <1%), and whether supplements reach target tissues at effective concentrations remains unclear. No large prospective cohorts have demonstrated mortality reduction in humans. Combined with other polyphenols or in food form (e.g., red wine, whole grapes) may differ from isolated supplement efficacy.
