Vitamin A supports vision, skin growth and repair and bone growth. It also provides protection from diseases such as cancer, macular degeneration, atherosclerosis and Alzheimer’s disease. Research has shown a relationship exists between low levels of carotenoid and Alzheimer’s disease. Insufficient levels of vitamin A are a major nutritional problem throughout the world including the United States. Vitamin A deficiencies can be caused by a lack of vitamin A in the diet, problems with recurrent infections and malabsorption problems such as diarrhea or fat malabsorption. Beta Carotene is not actually a vitamin, it is a precursor of vitamin A. Vitamin A has specific maintenance roles in our body and carotenoids such as beta carotene are stored in reserves that are easily converted into vitamin A. Beta-carotenes are antioxidants that protect cells against oxidative damage that can predispose cells to imbalances that may lead to inflammatory processes such as caner. Research has shown a relationship between low levels of carotenoids and Alzheimer’s disease.
