Parsippany, N.J.-based DSM’s Quali-E Vitamin E delayed functional decline in patients with mild to moderate Alzheimer’s disease by 19% or a clinically meaningful delay in progression of 6.2 months over the follow-up period compared to placebo. Further, daily high dose (2,000 I.U./day) supplementation of vitamin E for a long period of time (2.3 years) did not raise safety concerns. The company produces vitamin E for use in human nutrition — dietary supplements, food and beverage and infant nutrition.

The new study by the Department of Veterans Affairs Cooperative Studies Program, titled, “Effects of vitamin E and memantine on functional decline in Alzheimer’s disease,” was published in the Journal of the American Medical Association.

Vitamin E is an essential antioxidant nutrient that helps protect cell membranes by neutralizing free radicals, and also helps to maintain the immune system, support the health of red blood cells and maintain a healthy circulatory system. Vitamin E is found in all body tissues and is important for their health and proper functioning.
