An antioxidant-rich extract studied for circulation and cellular protection.
Grape Seed Extract is a well-studied source of proanthocyanidins, antioxidant compounds researched for their potential role in circulation and protecting cells from oxidative stress.
It's a common supporting ingredient in cardiovascular and performance-adjacent formulas, generally included for its antioxidant profile rather than a direct stamina effect.
As an antioxidant ingredient, its contribution here is more about supporting overall cellular health than driving an immediate performance change.
