Vitamin C

Other common name(s): none

Scientific/medical name(s): ascorbic acid, L-ascorbic acid, ascorbate

Description

Vitamin C is an essential vitamin the human body needs to function well. It is a water-soluble vitamin that cannot be made by the body, and must be obtained from foods or other sources. Vitamin C is found in abundance in citrus fruits such as oranges, grapefruit, and lemons, and in green leafy vegetables, tomatoes, potatoes, strawberries, red or green peppers, and cantaloupe.

Overview

Vitamin C is found in many vegetables and fruits, especially oranges, grapefruits, and peppers. Many studies have shown a link between eating foods rich in vitamin C, such as fruits and vegetables, and a reduced risk of cancer. On the other hand, the few studies in which vitamin C has been given as a supplement have not shown a reduced cancer risk.

This suggests that the activity of fruits and vegetables in preventing cancer is due to a combination of many things such as vitamins, fiber, and other phytochemicals and not to vitamin C alone (see Photochemical). Clinical trials of high doses vitamin C as a treatment for cancer have not shown any benefit. High doses of vitamin C can cause side effects in some people.

What is the history behind it?

By the early 19th century, it was known that a person could prevent and even cure scurvy by using citrus fruits. Finding out exactly why this happened took much longer. Researchers from different countries worked to learn more about it, and vitamin C was first isolated in pure crystalline form in 1927 by Nobel Prize winner Albert Szent-Gyorgyi. He published his paper the next year, calling the substance hexuronic acid. In 1933, the name ascorbic acid was suggested, and vitamin C has been studied ever since for its roles in nutrition and disease prevention.

In the 1970s, two-time Nobel Prize winner Linus Pauling advocated large doses of vitamin C (1,000 mg/day or more) to prevent colds and reduce their severity. In 1979, in a book called Vitamin C and Cancer, Pauling claimed that high doses of vitamin C could also be effective against cancer. His claim was based on a 1976 study he did with a Scottish physician in which 100 patients with advanced cancer were given 10,000 mg of vitamin C. The study concluded that the patients treated with vitamin C survived 3 to 4 times longer than patients not given the supplements. The Pauling study has been criticized by the National Cancer Institute for being poorly designed. Later studies done at the Mayo Clinic found that advanced cancer patients given the same dose of vitamin C did not survive any longer than those not given the supplement. At that time, the Mayo Clinic trials were criticized for not fully addressing all the issues related to the effects of vitamin C. But more recent studies still have not shown that supplemental vitamin C is effective in preventing or treating cancer.
