Tocotrienols are members of the Vitamin E family comprising of Tocotrienols and Tocopherols. Tocotrienols differ from the Tocopherol's in that they contain three double bonds in the side-shain (see molecular structure). Tocotrienols Isoprenoid side chain has three double bonds as compared to Tocopherol's saturated side-chain. In total, there are four types Tocopherols namely alpha, beta, gamma and delta and four corresponding of Tocotrienolsisomers.
Alpha Tocotrienols is 40-60 times more potent than normal Tocopherols making it one of the most powerful lipid soluble anti oxidants available.
Among vegetable oils, palm oil is the richest natural source of Tocotrienols. Tocotrienols are surprisingly not found in any other vegetable oils like soy bean oil, canola oil, rape seed oil and sunflower oil. Tocotrienols can be found naturally but in much lesser quantities in rice barn, barley, wheat gem and oats.
Palm Tocotrienols complex contains significant amount of D-Alpha-Tocopherol, D-Alpha-Tocotrienol, D-Gamma-Tocotrienol and D-Delta-Tocotrenol as compared to most other naturally found vitamin E, which are mostly Tocopherols.
