Ester-C® Calcium Ascorbate is a highly effective form of Vitamin C.
Vitamin C is required for the growth and repair of tissues in all parts of your body. It is necessary to form collagen, an important protein used to make skin, scar tissue, tendons, ligaments, and blood vessels. It also is essential for the healing of wounds, and for the repair and maintenance of cartilage, bones, and teeth.The main benefit of Ester-C® is its quick absorption and 24-hour retention in the immune system. It offers powerful, highly advanced immune support and is non-acidic so it is gentle on the digestive tract.
A recent clinical study in 2008 by Moyad MA et al showed that Ester-C® increased Vitamin C levels in the body for up to 24 hours, with white blood cell levels of Vitamin C also elevated in subjects receiving Ester-C® when measured 24 hours after initial dose. The presence of key metabolites such as threonate has been shown to be responsible for this increased level and retention of Vitamin C by the cells.Research by DM Bailey in 2001 on mice shows that a Vitamin C supplementation may affect physiological responses to hypoxia and therefore be beneficial at altitude. In 2005 Mansoor JK et al also did a double-blind trial of 18 mountaineers climbing to the Mt. Everest base camp. Research found that use of an antioxidant vitamin supplement (providing 1,000 mg of vitamin C, 400 IU of vitamin E, and 600 mg of lipoic acid daily) significantly improved symptoms of altitude sickness as compared to placebo.
