Chemically unique and biologically superior, Nova-E™ natural-source vitamin E (d-alpha tocopherol) is preferentially retained by body tissues. When compared to synthetic vitamin E, natural-source vitamin E is retained better and for a longer time in the body, making it more bioavailable. Vitamin E is an integral component of immune function. ADM is the largest producer of natural-source vitamin E and during stressful production stages, natural-source vitamin E may be especially beneficial.
