Vitamin E is not one substance but a group of chemically related substances called tocopherols and tocotrienols. Although alpha-tocopherol is perhaps the most recognized of the eight different vitamin E substances, and the one most often used in vitamin E supplements and in research studies, the gamma-tocopherol form has demonstrated potent anti-inflammatory and anticancer properties.
The anti-inflammatory abilities of gamma-tocopherol may prove helpful in men who suffer with prostatitis.
Research shows that gamma-tocopherol functions independently as well as synergistically with alpha-tocopherol (Elmadfa 1999). It is suggested that men who take a vitamin E supplement take either gamma-tocopherol or a product that contains both gamma- and alpha-tocopherol. The RDA for vitamin E is 15 mg (22.4 IU) daily.
