What is the recommended dosage for Vitamin E?

General: 15 mg (22.4 IU)/day (RDA); Skin Health: 15-400 IU/day

What are the side effects of Vitamin E?

Potential side effects include: Generally well-tolerated at recommended doses, Increased bleeding risk at high doses (> 400 IU/day), Nausea and diarrhea (rare).

What is vitamin E and how may it support skin health?

Vitamin E is a fat-soluble antioxidant that protects cell membranes from oxidative damage, including UV-induced lipid peroxidation in skin. When combined with vitamin C, oral vitamin E has shown synergistic photoprotective effects. It may also support skin barrier function and wound healing.

What dosage of vitamin E has been studied for skin outcomes?

Skin-related studies have used 400–1,000 IU of vitamin E (alpha-tocopherol) per day, often combined with vitamin C. The RDA is 15 mg (22.4 IU). Photoprotection studies typically combined 1,000 IU vitamin E with 2,000 mg vitamin C. The mixed tocopherol form may be more beneficial than alpha-tocopherol alone.

What are the potential side effects of vitamin E supplements?

High-dose vitamin E (above 400 IU daily) has been associated with increased bleeding risk and possibly increased all-cause mortality. It may interact with blood thinners and antiplatelet drugs. Topical vitamin E can cause contact dermatitis in some individuals. The tolerable upper intake level is 1,000 mg (1,500 IU natural form).

About

Vitamin E is the major lipid-soluble antioxidant in human skin, concentrated in the stratum corneum. It accumulates in cell membranes and protects polyunsaturated fatty acids from lipid peroxidation. Research suggests vitamin E works synergistically with vitamin C for photoprotection, and combined oral supplementation is associated with reduced sunburn response (higher MED).

How It Works

Fat-soluble antioxidant that accumulates in cell membranes and protects polyunsaturated fatty acids from lipid peroxidation; supports skin barrier function by maintaining stratum corneum lipid integrity; works synergistically with vitamin C to regenerate oxidized tocopherols.
