BioStacksWhy Vitamin E for Skin
When it comes to skin, Vitamin E is one of the most supporting nutrients to consider. Natural d-alpha-tocopherol is twice as bioavailable as synthetic dl-alpha-tocopherol, since the body only utilizes four of the eight synthetic stereoisomers—always check labels for the "d-" prefix. Mixed tocopherols (alpha, beta, gamma, delta) provide broader antioxidant protection than alpha alone. Tocotrienols, the other vitamin E family, offer additional cardiovascular and neuroprotective benefits not shared by tocopherols.
What dose to look for
Clinical studies typically use 50–268 mg of vitamin e. Equivalent to 100–400 IU natural d-alpha-tocopherol. Supplements that fall short of this threshold are unlikely to match what clinical trials achieved.
What form to look for
Avoid dl-alpha tocopheryl — synthetic, ~50% activity. For best results, choose d-alpha tocopherol or mixed tocopherols.
The evidence behind vitamin e
Research supporting vitamin e for skin is rated as strong. Natural d-alpha form is 2x more bioavailable than synthetic; mixed tocopherols provide broader antioxidant coverage Learn more
