~ Women's Health Study Concludes Vitamin E Safe

New Vitamin E Study Found 24% Reduction in Cardiovascular Death in Healthy Women and Older Women Experienced Even Greater Benefit - Women's Health Study Concludes Vitamin E Safe

PR Newswire, 07-06-05

CARSON, Calif., July 5, 2005 /PRNewswire via COMTEX/ -- Is vitamin E beneficial to human health? The Women's Health Study (WHS), published in the July 6th issue of the Journal of the American Medical Association (JAMA), found 600IU vitamin E is safe and significantly reduces the risk of cardiovascular death in healthy women. Conducted from 1992-2004 on 39,876 healthy women over the age of 45, the Women's Health Study found a "significant 24% reduction" in cardiovascular death in participants taking vitamin E. The study also "observed no significant effect of vitamin E on total mortality."

"The good news coming out of the Women's Health Study is that healthy women receive heart health benefits from taking vitamin E, and older women may reap even greater benefit. In women 65 and older, who never took estrogen and were on E, the study found an even greater reduction in the cardiovascular death rate. Had all these women not taken estrogen, one might surmise that the reduction in cardiovascular events among elderly women would have been even larger," commented Dr. Ishwarlal Jialal, M.D., Ph.D., Robert E. Stowell Endowed Chair in Experimental Pathology, Director of the Laboratory for Atherosclerosis and Metabolic Research and Professor of Internal Medicine and Pathology at UC Davis School of Medicine.

The study's objective was to test whether vitamin E supplementation decreases the risk of cardiovascular disease and cancer among healthy women. Women participating in the study randomly received 600IU natural source vitamin E or placebo every other day and 100 mg aspirin or placebo every other day. Strikingly, women over the age of 65 in the vitamin E group experienced a 26% overall reduction in major cardiovascular events, due to a 34% reduction in heart attack and a 49% reduction in cardiovascular death. However, researchers noted the overall reduction in cardiovascular deaths among all participants was possibly due to chance.

"A weakness of this study like previous anti-oxidant trials is the failure to report an objective assessment of compliance by measuring vitamin E levels in the blood. Vitamin E was given on alternate days with a compliance rate of 72% in the vitamin E group and an 11% drop-in rate in the placebo group," added Dr. Jialal.

The study elaborates "the single largest contribution to the reduction in cardiovascular deaths was fewer sudden deaths among women on vitamin E." Still the WHS researchers appear to downplay these "significant" findings by concluding vitamin E supplementation offers no harm or benefit. Moreover, they note their research indicates healthy women should not take it for the prevention of cardiovascular disease or cancer. Yet, the researchers acknowledged their findings of a decreased risk in cardiovascular death in participants as well as the significant benefit to women over age 65 contradict the study's overall findings and "should be explored further."

The Women's Health Study is the largest and longest randomized trial of vitamin E to date on healthy people. It addition to reducing the risk of heart disease, the study concluded vitamin E is safe and did not increase the risk of death in healthy women, refuting recent findings in the Miller meta- analysis (Miller, ER, Ann. Intern. Med. 2005), which suggested the contrary.

The Women's Health Study observed that while the Miller meta-analysis "raised the question of possible adverse effects on total mortality with high doses," it is important to recognize that the Miller trial was conducted on gravely ill participants "with cardiovascular risk factors and/or CVD, or at high risk for cancer." Therefore, one cannot apply its findings to the general healthy population. In contrast, the Women's Health Study conducted on nearly 40,000 healthy women with no risk factors found 600IU of vitamin E every other day "did not increase total mortality in healthy women."

The Women's Health Study was a randomized trial, considered more clinically sound than a meta-analysis. The Miller meta-analysis relied upon published summary statistics from 19 previously conducted trials, considered to be a distinctly inferior methodology when conducting a meta-analysis, making the results of the Miller study inconclusive at best. More research should be conducted on vitamin E in healthy people to better understand the scope of this nutrient's benefit.
