Gamma E 300 contains gamma tocopherol; one of the eight members of the vitamin E family found concentrated in plant seeds and vegetable oils. Typical vitamin E supplements only offer d-alpha tocopherol; which has been shown to deplete serum gamma tocopherol and alpha tocotrienol.* Gamma tocopherol is especially protective against reactive nitrogen species; free radicals that damage lipids; proteins and DNA.* Each softgel of Gamma E 300 contains more gamma tocopherol than a kilogram of pecans; pistachios; or walnuts. Keep out of the reach of children.
