Primary

Supports vasodilatory circulation

Resveratrol can affect endothelial nitric oxide and oxidative markers. Results for flow-mediated dilation in human trials are mixed, but the endpoint is still often watched. For people with cold extremities or heavy legs from sitting, changes in circulatory comfort and related markers are more often noticeable after several weeks of continued use.

Primary

Supports healthy-aging signaling

Cell studies repeatedly mention sirtuins and induction of antioxidant enzymes. Once inside the body it is metabolized quickly, so these paths are more often assessed with continued use. For people who want to approach vitality and metabolic markers through stilbene polyphenols, energy/mood and lab results are more often read together after several weeks.
