Vitamin E is a fat-soluble vitamin. Earlier the term vitamin E was used as the generic term for four tocopherols (α, β, γ, δ) and four tocotrienols (α, β, γ, δ). Nowadays only α-tocopherol is considered as vitamin E.
Vitamin E acts as an antioxidant and itcontributes to the protection of cells from oxidative stress. Good sources of vitamin E include for example vegetable oils, edible fats, full-grain products and nuts. Vitamin E deficiency is extremely rare in Finland.
Energy drinks contain ca. 4.0 mg of vitamin E per 100 ml, or about 40% of the recommended daily intake. Large intake amounts of vitamin E may prevent the absorption of vitamins A, D and K.
