The Active Ingredient Is: Resveratrol (from Polygonum cuspidatum extract)

Resveratrol is a polyphenolic compound labelled as a phytonutrient with recognised antioxidant activity. This form comes from Polygonum cuspidatum extract and is commonly used in dietary supplements to provide bioactive polyphenols.

This formulation includes resveratrol together with red wine and grape seed polyphenols, which collectively contribute to the antioxidant profile of the product.

What Does Resveratrol Do?

Resveratrol participates in normal cellular defence by acting as an antioxidant and by influencing pathways linked to cellular energy and ageing processes. Scientific hypotheses and EFSA-aligned understanding outline its role in endothelial function and vascular health maintenance as part of a broader polyphenol complex.

researcher Dr. Baur of Stanford University found that resveratrol activates SIRT1 and AMPK, enzymes linked to metabolic regulation and cellular protection, backing the concept of healthy ageing within the stated mechanism of action.
