Collagen formation: Collagen is a structural protein found in skin, tendons, ligaments, and blood vessels. Vitamin C is required for collagen synthesis—relevant for people who train, walk a lot, or want general connective-tissue support.
Antioxidant function: Vitamin C helps protect cells from oxidative stress and helps maintain the body’s antioxidant network.
Iron absorption (diet synergy): Vitamin C can enhance absorption of non-heme iron from plant foods (like beans, spinach, lentils)—a helpful bonus for many diets.
