After years of study, it appears the idea that vitamin C prevents the common cold is not necessarily true but it can shorten the duration. The conclusions come from a study by researchers at Australia's National Centre for Epidemiology and Population Health who reviewed more than 30 published trials investigating vitamin C's ability to prevent and treat the cold. The studies involved more than 10,000 participants and found that participants taking Vitamin C caught as many colds as people who were not taking extra vitamin C. However, the studies also found that cold symptoms did not last quite as long in people who took extra vitamin C daily through several winter months. On average, colds for people supplementing with Vitamin C were about half a day shorter than for people who did not take vitamin C. Overall, the preventive use of vitamin C supplementation reduced the duration of colds by about 8% in adults and 14% in children. Most of the prevention trials used a dose of 1 gram/day. Vitamin C helps to strengthen bones, cartilage and muscle, and aids in the absorption of iron. Vitamin C is also a highly effective antioxidant.It’s recommended daily value is 90 milligrams of vitamin C per day for adults. Vitamin C is water soluble and potency is reduced by high temperature very quickly. For best shelf-life, don’t store near ovens, stoves or near bathroom showers. Researchers are learning more everyday about the vital role of oxidative damage in diseases ranging from asthma to stomach ailments to mood enhancement and cardiovascular support. The importance of Vitamin C is growing literally by the day. There is no doubt that future research will uncover even more astonishing findings on the health benefits of Vitamin C.
