Tocotrienols are members of the vitamin E family. Like vitamin E, tocotrienols are potent antioxidants against lipid peroxidation (the damaging of fats by oxidation).^{1, 2}

Where are they found?

Tocotrienols are found primarily in the oil fraction of rice bran, palm fruit, barley, and wheat germ. Supplemental sources of tocotrienols are derived from rice bran oil and palm oil distillates. Tocotrienol supplements are available in capsules and tablets.

Tocotrienols have been used in connection with the following conditions (refer to the individual health concern for complete information):
