Evidence-Based Comparison
Vitamin C vs Vitamin E: Water-Soluble vs Fat-Soluble Antioxidant Duo
How these two premier antioxidants work synergistically to protect cells.
Key Takeaway (TL;DR)
Vitamin C defends aqueous compartments and promotes collagen synthesis, while Vitamin E protects lipid membranes against peroxidation. They work in tandem: Vitamin C regenerates oxidized Vitamin E, creating a powerful antioxidant cycle.
Complementary partners: Vitamin C regenerates Vitamin E for optimal defense.
