Vitamin E Succinate takes vitamin E s antioxidant action one step further, and may help bring vitamin E into and across cell membranes. Succinate feeds directly into the Krebs cycle, our major metabolic pathway for generating energy. This extra dimension from succinate significantly extends the protective properties of vitamin E. Then why not have vitamin E as succinate in all antioxidant formulations? Because the succinate form of vitamin E is derived from soy. However, the amount of residual soy antigens in this product is very small. This form may enhance membrane integration of Vitamin E.
