Vitamin E Mixed Tocopherols — Supplements
Full-spectrum vitamin E complex providing antioxidant protection for lipid membranes and lipoproteins.
Overview
Vitamin E encompasses eight naturally occurring forms: four tocopherols (alpha, beta, gamma, delta) and four tocotrienols. Alpha-tocopherol is the most biologically active and the only form that meets the RDA. Mixed tocopherol supplements provide the full spectrum, with gamma-tocopherol demonstrating unique anti-inflammatory properties (trapping nitrogen-based free radicals) that alpha-tocopherol alone does not provide. While the ATBC and SELECT trials raised concerns about isolated alpha-tocopherol, mixed tocopherols may offer a more balanced and physiological antioxidant approach.
Indications
- Lipid peroxidation protection
- Cardiovascular antioxidant support
- Skin health and photoprotection
- Vitamin E deficiency prevention
Mechanism of Action
Alpha-tocopherol donates a hydrogen atom to lipid peroxyl radicals, terminating lipid peroxidation chain reactions
