Ultimate E contains a mixture of all tocopherols and utilizes molecular distillation to remove allergenic soy residues. Vitamin E is a vital antioxidant, and has been shown to benefit the cardiovascular system. Thorne's Ultimate-E contains mixed tocopherols and provides vital antioxidant activity in fat-soluble tissues. Numerous clinical studies have shown vitamin E is beneficial to the cardiovascular system. Ultimate-E, with its naturally occurring ratio of tocopherols, is an efficient way to supplement vitamin E – without the addition of soy oil as a filler. And recent studies looking at mixed tocopherols indicate they have a stronger inhibitory effect on lipid peroxidation than alpha-tocopherol alone, indicating a more potent antioxidant effect. Thorne's vitamin E ingredient is extracted from a mixture of vegetable oils, including soy oil. However, any potentially allergenic soy residue is removed during the distillation process, and Ultimate-E is not diluted with soy oil.
Tocopherols provide protection from free radicals and other by-products of oxygenation, including lipid peroxides and singlet oxygen radicals. Gamma-tocopherol inhibits the enzyme cyclooxygenase, whereas alpha-tocopherol does not appear to have a significant effect on this enzyme. Human studies comparing diets supplemented with gamma- and alpha-tocopherols, to diets supplemented primarily with only alpha-tocopherol, found more DNA protection in the mixed-tocopherol group than the alpha-tocopherol group. Because the tocopherols in Ultimate-E come from a natural source, the tocopherol profile can vary slightly from batch to batch, although extra alpha-tocopherol is added to each batch that is manufactured to standardize the amount of this important tocopherol to 500 IU per gel cap.
