Both gamma- and delta-tocopherol may be necessary for preventing lipid peroxidation and in counteracting the pro-oxidant effect of alpha-tocopherol. Moreover, all tocopherols except beta-tocopherol inhibit smooth muscle proliferation. In our research, a preparation of mixed tocopherols, containing gamma-, delta-, and alpha-tocopherol (5:2:1), has been shown to have better antioxidant and anti-inflammatory actions than alpha-tocopherol alone. This mixture did not have any adverse effects in a limited number of preliminary clinical investigations. Thus, among the tocopherols, alpha-tocopherol is not the only important isomer for human health.

NOTE: A.C. Grace Company has provided a MIXED TOCOPHEROLS product for the past nearly five decades! Roy Erickson knew, in the late 50s, that a MIXED TOCOPHEROLS high in GAMMA- and ALPHA-, along with Delta- and Beta-tocopherols provides maximum benefit to the body. That is why he developed an exclusive, proprietary blend of the four tocopherol isomers.

PLUS! He left out all diluents, colors, additives, soy protein, gluten and oil filler that can turn rancid to provide a superior product with maximum vitamin E benefit!
