D-alpha-tocopheryl succinate is a natural form of fat-soluble vitamin E that is one of the strongest antioxidants.
The source of vitamin E is very significant because synthetic forms are characterised by much lower bioavailability. Unlike natural forms (d-alpha-tocopheryl succinate, d-alpha tocopheryl acetate and etc.), synthetic compounds are designated with the prefix “dl” (e.g. dl-alpha-tocopheryl succinate that is a completely synthetic form). Depending on the condition of the body, the absorption of natural vitamin E may vary from 20 to 70%.
In comparison with alpha-tocopherol, alpha-tocopheryl acetate and alpha-tocopheryl nicotinate, it is believed that d-alpha-tocopheryl succinate is the most effective form of vitamin E, especially when it comes to anti-cancer effects. Vitamin E as d-alpha-tocopheryl succinate is a frequent ingredient of vitamin-mineral supplements which promote general health of the body and adds vitality.
