Ajaz Ali (Pharmaceutical Review). Dr. Linus Pauling, a two-time Nobel Prize winner, took high doses of vitamin C for almost forty years and died at the ripe old age of ninety-three. He believed that his life was prolonged for twenty years because of his high vitamin C intake. Sounds great, and Pauling certainly makes a valid argument but unfortunately there isn’t any strong evidence to support this claim.
Vitamin C and vitamin E, often referred to as antioxidant vitamins, have been suggested to prevent cell damage in humans, thereby lowering the risk of certain chronic diseases including high blood pressure, stroke, and asthma. Many studies have tried to prove this, but with no obvious results. Very few side effects exist with vitamin C, so there is no major downside to adding a vitamin C supplement to your daily regimen, though occasional reports of nausea, heartburn, gas, or diarrhea are noted with higher doses. A more prudent approach is to eat a balanced diet including fruits and vegetables and avoid dangerous activities like smoking.
