Vitamin E is a collective name for a group of eight different compounds; alpha, beta, gamma and delta-tocopherol and alpha, beta, gamma and delta-tocotrienol. Until recently, most vitamin E supplements only contained alpha-tocopherol-one of the most active forms of vitamin E. Several studies have been published that demonstrate the importance of consuming the entire family of vitamin E compounds, as they each have specific biochemical and physiological effects that benefit the body. Perfect E features the complete family of vitamin E compounds. It also contains the patented Tocomin brand of tocotrienols. This brand of tocotrienols has been used in clinical studies and shown to be a superior source of complete tocotrienols.
