In most animals, the water soluble nutrient, ascorbic acid, is synthesised from glucose. In humans a genetic lesion prevents us from making it and diet is the sole source of this vitamin. As a cofactor for many enzyme systems, ascorbic acid is involved in the synthesis of collagen, carnitine, endocrine hormones, and neurotransmitters.
Many of the symptoms of the vitamin C deficiency disease scurvy can be attributed to weakened collagen structures, including bruising, muscle weakness, gum deterioration, and poor wound healing.
Vitamin C as Ester C is known to be a potent immune stimulating nutrient. It has been shown to inhibit viral replication and may reduce the severity of the common cold. A recent study of one hundred and sixty-eight volunteers were randomized to receive a placebo or a vitamin C supplement, two tablets daily, over a 60-day period. The results showed that vitamin C supplement may prevent the common cold and shorten the duration of symptoms.
Some medicines can be affected by vitamin C. Women on the contraceptive mini-pill should not take excessively large doses of vitamin C at the same time of day as this may reduce the pill's effectiveness. Upper safe level: 2000mg (long term usage); 3000mg (short term usage).
During times of chemical, emotional, psychological, or physiological stress, vitamin C is excreted at a significantly increased rate. Thus a higher intake of vitamin C is required for immune protection when the body is under stress.
Up to two grams daily or as recomended by your nutritionist. One negative side-effect of continued large doses of usual forms of vitamin C is gastrointestinal discomfort and diarrhoea. These effects are due in large part to the acidity of ascorbic acid itself. As a mineral ascorbate, Ester-C circumvents many of these problems because it has a neutral pH. At the same time, this new process introduces an important metabolite of vitamin C so it is present along with ascorbate when the supplement is taken.
