An Update on Vitamin E, Tocopherol and Tocotrienol—Perspectives

Vitamin E, like tocotrienols and tocopherols, is constituted of compounds essential for animal cells.

In order to prevent lipid oxidation, the plants mainly accumulate tocochromanols in oily seeds and fruits or in young tissues undergoing active cell divisions. From a health point of view, at the moment there is a great interest in the natural forms of tocochromanols, because they are considered promising compounds able to maintain a healthy cardiovascular system and satisfactory blood cholesterol levels.
