Vitamin C is an essential, water soluble vitamin. It has other names such as ascorbic acid and has been called the most popular supplement in the world. It is essential because humans can not synthesize vitamin C and must obtain it from their diet. I’m just going to briefly summarize the things I think are worth knowing about vitamin C. Everything I’m going to say is evidence based with research to back it up.
It is well known as a vitamin supplement taken to prevent the common cold. I looked up the data for this. A 2013 meta-analysis of 29 trials (n = 11,306) showed a small but significant 8 percent reduction in the duration of cold symptoms in adults regularly taking vitamin C supplements (at least 200 mg/day). In the general population it does not reduce the risk of developing a cold or getting sick. It does appear to have a protective effect in highly active individuals. In other words, the evidence is not strong that vitamin C is dramatically helpful in preventing or treating the common cold in most people.
Vitamin C has not been shown to reduce the risk of developing cancer, cardiovascular disease or coronary heart disease, cataracts or macular degeneration
