Because vitamin C is an antioxidant, it can block some damaged caused by [[free radicals]] created as by-products during the digestion of food.  A buildup of free radicals can cause or contribute to a larger variety of medical problems, such as arthritis, cancer, and heart disease.

Consuming too much vitamin C is rare, due to the body's inability to store it and build up an excess.  A large quantity of vitamin C consumed in a short period of time is the only way to achieve vitamin C [[toxic]]ity, which can lead to stomach pains and diarrhea, but these symptoms will stop with the decrease in vitamin C consumption.  It is difficult to create vitamin C toxicity without the use of vitamin supplements, and, since the body does not store vitamin C, the effects of toxicity are temporary.
