Gamma-tocopherol, a form of vitamin E found in many plant seeds but not widely available in nutritional supplements, might halt the growth of prostate and lung cancer cells, say US researchers. Their findings lend weight to the growing support for a mixture of vitamin E forms, over single form alpha-tocopherol, in supplements. Gamma-tocopherol, found naturally in walnuts, sesame seeds and corn, was found to hold back the proliferation of lab-cultured human prostate and lung cancer cells, reports the team from Purdue University in the 13 December online edition of the Proceedings of the National Academy of Sciences.
