The American Fun Science website on August 14th? The writer is John Swartzberg, an honorary professor of medicine at the University of California, Berkeley School of Public Health.nearly 100 years ago, researchers at the University of California, Berkeley, discovered the
vitamin E
. Since then, many studies have accepted the potential health benefits of this antioxidant. After all, in a laboratory environment, they mediat potentially harmful free agents. Can they produce the same benefits inside the body? For years, nutritional supplement manufacturers and researchers have predicted that vitamin
E
can help prevent cancer, heart disease and Alzheimer's disease, as well as protect vision and maintain skin gloss. Sales of vitamin E supplements have soared, driven
and
advertising., what exactly did the study draw? Early studies that found vitamin supplements to be beneficial, mostly for heart disease, were observational and sometimes not well-designed: researchers asked people if they took vitamin
E
supplements and then checked their health status, the paper said.more recent studies, mostly well-designed clinical trials, have found no benefit from vitamin supplements. In fact, a few studies have shown that high doses of
E
may be harmful.Are here some of the results from the more important study around vitamin
E
:Heart Disease and Stroke the article says that in 2008, Physician Health Research II looked at more than 14,000 male doctors who took high doses of vitamin
C
or vitamin
E
over an eight-year period. Neither supplement reduced the incidence of heart disease, stroke or cardiovascular disease. In fact, taking vitamin
E
slightly increased the risk of hemorrhagic stroke. Analysis of several studies conducted in 2010 showed that vitamin
E
increased the risk of hemorrhagic stroke by 22 per cent.Longevity article said a review of several studies involving nearly half a million people by Cochrane International, an independent body that evaluates evidence from health research, found that antioxidant supplements do not extend life or protect against disease. Other large review bodies have also suggested that vitamin
E
and other antioxidants are associated with increased mortality.a 2007 study funded by the U.S. National Cancer Institute, vitamin supplements, including
E
, are not protective. Smokers who
vitamin
E have a slightly higher risk of lung cancer. Although this is not the conclusion, the researchers warn smokers that taking supplements "may be harmful."a 2011 studythe National Cancer Institute looked at whether vitamin
E
could help prevent prostate cancer, according to a 2011 study by the National Cancer Institute. Early studies have found that vitamin
E
not helpful or harmless in this regard. The three-year, large-scale study of 35,533 men produced surprising results: healthy men taking vitamin
E
had a higher incidence of prostate cancer than other men., there are no clinical studies showing that vitamin
E
supplements are good for your health. Most of the recent clinical trials have come to negative or inclusive conclusions.
