Vitamin C is one of the most widely used nutritional supplements. Most animals can produce vitamin C naturally. Humans, on the other hand, cannot and must get vitamin C from other sources.
It is clear that vitamin C deficiency is harmful. Scurvy is a terrible condition that can cause bleeding gums, skin hemorrhage and easy bruising, weakened bones, poor wound healing, susceptibility to infection, and depression. Although most people get enough vitamin C in their normal diet to avoid the effects of scurvy, additional supplementation can have noticeable benefits.
Vitamin C is an important antioxidant. It is also one of the few supplements that encourages and protects other antioxidants in the body such as vitamin E and glutathione. Vitamin C provides many other benefits to the body. It is critical for the liver’s ability to detoxify substances that pass through the body. Vitamin C also reduces the risk of heart disease by preventing the oxidation of cholesterol. It is required for the production of collagen which is an important component of cartilage, tendons, ligaments, bone and blood vessels. One of the most common uses of vitamin C is to boost immunity. Vitamin C is very concentrated in the white blood cells, and increased activity of those cells and improves antibody response.
Most people who consume fruits and vegetable on a regular basis will not need vitamin C supplements, but for those requiring supplementation a general recommendation is that they take 500 milligrams a day. People who are dealing with a condition that can be helped by vitamin C can take much higher doses. Most people can take 2000 milligrams a day without experiencing any side effects. Vitamin C is non toxic, however, very high doses can cause diarrhea and digestive upset. These symptoms go away when the dose of vitamin C is decreased.
