Manufacturers also commonly convert the phenol form of the vitamins with tocopheryl free hydroxyl nicotinate to estersusing acetic or succinic acid. Naturally sourced d-alpha-tocopherol can be extracted and purified from seed oils, or gamma-tocopherol can be extracted, purified, and methylated to create d-alpha-tocopherol.

This condition could be changed by additional feeding with wheat germ. No controls or other tocopherol esters were included in the study and the number of subjects was small. Although the mono-methylated nicotinate ddd-gamma-tocopherol is the most prevalent form of vitamin E in oils, there is evidence that rats can methylate this form to the preferred alpha-tocopherol, since several generations of rats retained alpha-tocopherol tissue levels, even when fed only gamma-tocopherol through their lives. In tocopherols, this is due to the preference of the tocopherol binding protein for the alpha-tocopherol form of the vitamin. Nutr Metab Cardiovasc Dis.
