Vitamin E products not versatile enough to prevent Alzheimer’s disease
Vitamin E products sold in pharmacies and stores are usually not versatile enough to protect from Alzheimer’s disease, says Research Director at the Karolinska Institute Miia Kivipelto.
The most common vitamin E products contain only one form of vitamin E, while the overall number of vitamin types is eight. Helsingin Sanomat reported last week of Kivipelto’s Finnish-Swedish study which reports that these eight different types may protect against Alzheimer’s disease. If a vitamin E product contains only one dose of a single type of vitamin E, its use may be compared to a four-legged chair with one leg that is longer than the rest, Kivipelto says. “The balance will shake”. According to Kivipelto ideal vitamin E intake takes place through adequate consumption of vegetable oil, peanuts, green vegetables, avocado and whole grains. The vitamin products in the markets often contain D alpha-tocopherol or D alpha-tocopheryl acetate, which is often found in most multivitamin products, such as Pharma Nord’s Bio vitamin E. University Pharmacy has developed its own Professorin E-vitamiini (Professor’s vitamin E), which contains all five kinds of vitamin E. “We are headed in the right direction, although it is rather early for commenting on results without specific studies”, Kivipelto says.
She states that consuming large doses of vitamin E may involve side effects, such as an increased risk of a stroke. Kivipelto points out that elder people often consume several medications simultaneously, which may have unpredictable outcomes.
The daily need for vitamin E amounts to approximately 15 milligrams for adults. Kivipelto described this amount, which multivitamin products often approximately contain, as rather safe. Adverse effects have been associated with significantly higher dosages, almost twenty times the recommendation. “It is important to keep in mind that vitamin products should not be used to replace a versatile diet, which often contains many forms of vitamin E”, Kivipelto says.
