Vitamin C is one of the best known vitamins for boosting overall health and energy. However its most common use, as a straightforward cure for the common cold, is actually a myth.

Contrary to popular belief, the vast majority of studies indicates that vitamin C has little or no positive effect on the common cold, although there is strong evidence that it may generally strengthen the immune system and therefore help to ward off colds and flu before they occur.

Vitamin C is also notable because while it is an essential component of many processes within the body, humans, unlike almost all organisms, do not produce it internally. This makes vitamin C supplementation an essential part of maintaining a healthy body.

One of vitamin C's most controversial applications is as a cancer treatment. For example, in one recent study, researchers found that injecting large doses of vitamin C directly in to tumors in mice reduced tumor size and growth by up to fifty percent.

Another study found that when terminal cancer patients were given large doses of vitamin C, they reported an improvement in their cancer symptoms as well as their general health. Vitamin C treatment is still very controversial, however, and there is little consensus on just how effective vitamin C may be in treating serious disease.

Vitamin C is also an antioxidant, which means that it protects against free radicals, or unstable molecules within the body that can contribute to a variety of ailments such as heart disease, neurological disease, and certain types of cancer. Free radicals are also believed to contribute to the bodies aging process. Taking antioxidants, such as vitamin C, can protect against the many ailments that free radicals contribute to.

Linus Pauling, a pioneering vitamin C researcher, believed that vitamin C in large doses could have a significant positive effect on heart disease, with new evidence that vitamin C may, indeed, reduce the chance of developing cardiovascular conditions.

Vitamin C is widely available as a supplement, and the best food source of vitamin C is citrus fruits such as oranges and grapefruits, as well as strawberries, peppers and tomatoes.
