Can vitamin E help reduce my risk of heart disease or stroke?

As is the case with many vitamins, observational studies suggested that people with higher vitamin E intakes were less likely to develop heart disease. Results from the Women's Health Study, an observational study that followed about 36,000 women for more than 10 years, showed that a daily supplement of 600 IU of vitamin E did not reduce the risk of having a heart attack or stroke. However, it did decrease the risk of dying from cardiovascular disease by about 25%.

Expectations for vitamin E faded further as the results from randomized trials trickled in. The Heart Outcomes Prevention Evaluation-The Ongoing Outcomes (HOPE-TOO) study included almost 4,000 volunteers, ages 55 and over, with vascular disease or diabetes. Half took 400 IU of vitamin E daily, and the others took a placebo. After seven years, the vitamin E hadn't provided any more protection against heart disease or cancer than the placebo. In addition, the vitamin E takers were more likely to suffer heart failure and to be hospitalized for the condition.

The Physicians' Health Study also found no benefit from 400 IU of vitamin E taken every other day for preventing heart disease, stroke, or death from heart disease. In fact, vitamin E increased the risk of bleeding (hemorrhagic) stroke.
