The Truth About Vitamin E
It doesn't stave off heart disease, so who should take it?
March 27, 2000 (Petaluma, Calif.) -- When Alice Nadler heard the latest on vitamin E, she began to wonder if the experts really know what they're talking about. "I've been taking vitamin E for a couple of years, ever since my doctor recommended it as a way to lower my risk of heart disease," says the 40-year-old mother of two boys, who lives in Northern California. "So now they're saying it may not?"
Like Nadler, many Americans began popping vitamin E -- now one of the top-selling supplements nationwide -- a few years ago after studies suggested that it might protect against heart disease. In one study published in Lancet in 1996, men and women with cardiovascular disease who took the vitamin each day cut their risk of a second heart attack almost in half. In 1993, the Journal of the National Cancer Institute published findings from a five-year Chinese study that followed nearly 30,000 adults. Those who took vitamin E supplements were 9% less likely to die during the study period.
Many researchers cautioned that more investigations were needed to confirm the power of E. But privately, some also admitted that they were taking a daily dose of the vitamin themselves, because the initial findings looked so good.
High Hopes Take a Tumble
Now comes news from a January 20, 2000 issue of the New England Journal of Medicine that the golden pill may
not live up to its promise. Canadian researchers tracked 2,545 women and 6,996
men aged 55 or older who took either vitamin E or a dummy pill. After five
years, those taking the vitamin were no better off than those taking the dummy
pill, suffering just as many heart attacks, strokes, and deaths from
cardiovascular disease. The findings, ironically, are part of a study called
HOPE, or the Heart Outcomes Prevention Evaluation.
