America's Compounding Center says this about Vitamin C:
"Vitamin C, also known as ascorbic acid, is a water-soluble vitamin found in fresh fruits and vegetables such as oranges, green peppers, broccoli, tomatoes, kiwi, and strawberries. Water-soluble vitamins are not stored by th ebody, therefore they need to be replaced regularly in the diet. Vitamin C is a natural antioxidant, helps the body maintain skin and bone health, and aids in wound healing. Vitamin C has been studied for many uses, including prevention of the common cold, cancer, and heart disease, as well as treatment of high blood pressure, and acceleration of wound healing in patients with severe burns. Causes of vitamin C deficiency include poor dietary intake, cigarette smoking, malabsorption syndromes, and genetic disorders. Symptoms of Vitamin C deficiency include fatigue, petechiae, bleeding or swollen gums, dry skin, brittle nails and bone changes. In cases of severe deficiency, a patient can develop scurvy. The UMDF recommends taking 100-500 mg of vitamin C one to three times daily. Adverse effects associated with high-dose Vitamin C supplementaton include nausea, stomach upset, diarrhea, and kidney problems. "
