...insurance against gaps in the diet, supplements can provide optimum dosages of natural therapeutic agents that may help prevent and treat age-related diseases. Consider vitamin E. Oil-rich seeds and nuts are the main food source of it. Many studies suggest that doses in the range of 200 IUs to 400 IUs of alpha-tocopherol (or, better, 80 mg to 160 mg of the whole complex, including tocotrienols) offer the best antioxidant protection against common age-related diseases. Nuts are good for you, but you would have to eat far too many to get that amount of vitamin...
Vitamin E was once thought by some to be the cure for nearly everything. Observational studies suggested that moderately high doses (400 International Units, or IUs) could prevent heart disease, cancer and dementia - and make your skin glow, too. But lately scientists, using more rigorous tests, have had trouble substantiating some of those benefits. Now comes what may be the crowning blow - at least with respect to staving off heart disease. A double-blind, placebo-controlled trial, published in the Journal of the American Medical Association last week, found that taking 400 IUs of vitamin E each day did nothing...

...comes what may be the crowning blow?at least with respect to staving off heart disease. A double-blind, placebo-controlled trial, published in the Journal of the American Medical Association last week, found that taking 400 IUs of vitamin E each day did nothing to prevent heart attacks or strokes in a group of nearly 10,000 mostly elderly patients with cardiovascular disease or diabetes. This disappointing news comes on the heels of the Women's Health Study finding earlier this month that vitamin E confers no cardiac benefit on healthy women age 45 or older...
...There's no need to panic. If you take a multivitamin, you're getting only 30 IUs of vitamin E, and this has long been shown to be a safe amount. And 400 IUs may yet prove to be fine. For complicated statistical reasons, the heart-failure finding could easily be a fluke, the study's coordinating investigator readily admits...
