What You Need to Know About Vitamin E, Selenium and Prostate Cancer

Comments (1)

Both vitamin E and the mineral selenium have long been under study for their potential to prevent or slow the progression of prostate cancer. In one early study, men who took vitamin E supplements had a 34 percent reduction in the incidence of prostate cancer. Another study found that men who took selenium supplements had a two-thirds reduction in the risk of developing prostate cancer.

Results from a large, nationwide clinical trial called SELECT (Selenium and Vitamin E Cancer Prevention Trial) have failed to show a benefit from use of either selenium or vitamin E. Of greater concern: Findings from SELECT demonstrated an increased risk of prostate cancer among vitamin E users.

In recent years, a high intake of calcium has come under scrutiny as a possible risk factor for prostate cancer. In one study, the risk of developing advanced prostate cancer was 2.5 times higher among men who consumed 2,000 mg or more of calcium each day than among men with a daily consumption of 500 to 749 mg. For now, a sensible approach is to limit calcium consumption to no more than 1,200 mg per day through food sources.

Evidence for the effect of vitamin E on prostate health appears to be contradictory. But to date it alpha-tocopherol has been the surrogate for vitamin E. Until a mix of tocopherols including gamma-tocopherol is used, I would conclude that no studies have demonstrated one way or the other whether vitamin E is or is beneficial or harmful. If you take the alpha isomer to the exclusion of the others, competitive exclusion can create a vitamin E deficiency.
