What you are buying
Isotonix OPC-3 is an isotonic antioxidant powder in the exclusive Isotonix line (Taiwan naming: 愛尚它). Listings commonly describe a plant OPC blend — grape seed, pine bark extract (Pycnogenol), red wine extract, bilberry, and citrus bioflavonoids. This page helps you pick the right country checkout; for ingredient cards and research links, start at the main product guide.
Shoppers usually compare serving size (for example 30 vs 90 servings), whether the live label matches the name they searched, and which storefront ships to their address. We do not promise health outcomes — lifestyle shopping content only.
