Combining Vitamin E with Selenium kills prostate cancer cells

Oct 09, 2008

Researchers at the University of Wisconsin have just reported that a combination of vitamin C and E administered to human prostate cancer cell cultures kills the prostate cancer cells. The finding adds support to the hypothesis that vitamin E and selenium are of value in prostate cancer prevention, which is being investigated by the twelve-year Selenium and Vitamin E Chemoprevention Trial (SELECT) that includes over 32,000 healthy men.

Adding Vitamin E Succinate or Selenium alone modestly inhibited the growth and viability of the prostate cancer cells, adding the combination of the two dramatically inhibited prostate cancer cell growth while having no effect on either growth or viability of normal cells. It is important to note that some cell cultures were androgen sensitive and some were androgen resistant meaning the combination affected prostate cancer from early stage to late stage. The study is published in the November 1, 2008 issue of The Prostate.
