Therapeutic Uses Since its discovery, vitamin C has been regarded by some as the “universal panacea”. Other proponents of vitamin C felt that given the right way, with proper technique, in frequent enough doses, in high doses with certain additional agents and for a long period of time (26) can prevent and even cure a wide range of common and deadly diseases like the common cold and heart disease. Probably the most controversial is the putative role of ascorbate in the management of AIDS remains unresolved, more than 16 years of studies published in the Proceedings of the National Academy of Sciences of the United States, showing that non-toxic doses of ascorbate suppress HIV replication in vitro (29). In animal models with lead poisoning, vitamin C has demonstrated “protective effects” on the nerve and muscle abnormalities induced by lead poisoning (33).In smokers, blood lead levels decreased by 81 on average, when supplemented with 1000 mg vitamin C, while 200 mg are ineffective, suggesting that vitamin C supplements can be an inexpensive and convenient way to reduce lead levels blood lead (34). The Journal of the American Medical Association published a study which concluded, based on analysis of blood lead levels in subjects from NHANES III (Third National Health Examination Survey) as the independent and inverse relationship between lead levels and plasma vitamin C, if causal could have public health implications for control of lead poisoning. (35) Vitamin C has limited popularity as a treatment for Autism generated. A study in 1993 of 18 children with autism found a reduction in some symptoms after treatment with vitamin C (36).Small clinical trials have found that vitamin C could improve the bill, motility and sperm morphology in infertile men (38).

A preliminary study published in the Annales of Surgery (USA), found that the administration and antioxidant supplementation using -tocopherol and ascorbic acid reduces the incidence of organ failure and shortens ICU stay in this cohort of critically ill surgical patients (40 ). Dehydroascorbic acid, the major form of vitamin C oxidized in the body, has been shown to reduce neurological deficits and death followed a stroke, due to its ability to cross the blood brain barrier, while vitamin C or the L-ascorbate did not manages to cross this barrier (41).In a study published in the Proccedings of the National Academy Sciences in 2001, the authors concluded that “a pharmacological strategy to increase brain levels of ascorbate in stroke has tremendous potential to represent the timely translation of basic research in relevant therapy for stroke in humans. In January 2007, FDA Food and Drug Administration approved a phase I toxicity test to determine safe doses of intravenous vitamin C as a possible treatment for cancer who have exhausted other therapies and conventional options.In February 2007, an uncontrolled study of 39 patients with terminal cancer, showed that on subjective questionnaires, patients reported an improvement in health, cancer symptoms and daily function after administration of high doses of vitamin C intravenously. (44 ) The authors concluded that “although there is still controversy regarding anticancer effects of vitamin C, the use of it is considered a safe and effective therapy to improve the quality of life of patients with terminal cancer. In August 2008, an article published in Proceedings of the National Academy of Sicences by Mark Levine and colleagues at the National Institute of Diabetes and Kidney Diseases, found that direct injection of high doses of vitamin C reduces weight and tumor growth in 50 inmouse models of ovarian cancer, brain and pancreas.
