The Primary Ingredient Is: Grape Seed (Vitis vinifera) Powder

Grape seed powder is the dried seed part of Vitis vinifera, rich in polyphenols and proanthocyanidins that help antioxidant activity. This form uses the whole seed to keep the full polyphenol profile for broad antioxidant potential.

This formula includes grape seed powder in a vegan capsule format, standardised to keep natural polyphenols while staying non-GMO and allergen-light.

What Does Grape Seed Do?

Grape seed polyphenols take part in bodily antioxidant processes and may support endothelial function, contributing to vascular health as described in EFSA-aligned context. The information reflects proposed mechanisms of grapeseed antioxidants and their role in cellular protection.

Dr. Sato of the University of Tokyo found that grape seed polyphenols boost endothelium-dependent blood vessel relaxation, supporting the idea of vascular health benefits.
