Tocotrienol Form of Vitamin E Inhibits Breast Cancer
Palm tocotrienols were investigated for their effects on estrogen positive and estrogen negative breast cancer cells. Tocotrienols caused complete suppression of growth at 20mcg/ml saturation. The tocotrienols did not work by suppressing estrogen or by inhibiting insulin growth factors but acted in a different way. All four fractions of tocotrienols inhibited breast cancer tissue growth but the gamma-tocotrienol and delta-tocotrienol were stronger. Lipids, May 1998.
Tocotrienol Protects Brain Cells
Alpha-tocotrienol blocked brain neuronal cell death caused by glutamate over-excitation, by Homocysteine free radical damage and by a potent neuro-toxin (1-buthionine sulfoximine). The tocotrienols treated cells continued to grow and function in a healthy manner even under glutamate exposure. Journal of Biological Chemistry, October 31, 2003.
Dietary Antioxidants protect you from Developing Diabetes
A study of 2,285 men and 2,019 women aged 40 to 69 who were free of diabetes and followed for 23 years found that vitamin E intake significantly reduced the risk of developing type 2 diabetes. Gamma-tocopherol, alpha-tocopherol, delta-tocopherol, and beta-tocotrienol all reduced the risk of developing type 2 diabetes. The carotenoid beta-cryptoxanthin also reduced the risk.

Vitamin E Isomers Prevent Stroke in Mice
Different types of vitamin E have been shown to reduce stroke-induced brain damage. In a study of mice with stroke induced in their brain, different forms of vitamin E were supplemented before and 3 hours after inducing a stroke in the middle cerebral artery. Alpha-tocopherol, gamma-tocopherol, and alpha-tocotrienol all significantly reduced the size of the stroke. Neuroscience Letters, January 30th, 2003.
Vitamin E and Skin Protection
In normal human skin scientists found the following forms of vitamin E that protect the skin from aging - Alpha-tocopherol, Gamma-tocopherol, Alpha-tocotrienol, and Gamma-tocotrienol. Free Radicals in Biology and Medicine, February 1st, 2003.
