Vitamin C (also known as ascorbic acid) is readily available in fruits and vegetables. Many drinks and beverages are now fortified with Vitamin C and the tablet or syrup is readily available as over-the-counter (OTC) medicines in several countries.

Why is Vitamin C so important? It is an antioxidant that facilitates the growth and restoration of bones, gums and body tissue. So it is essential for normal body metabolism and growth.

How much Vitamin C do we need daily? This depends on several factors such as metabolic rates, weight and age. The human body ordinarily stores about 1500mg of Vitamin C. Most scientists agree that a minimum of 10mg is needed daily. Recommended daily allowance ranges from one country to another. It may be as low as 30mg for moderately active adults. According to Food and Drug Administration (US) adults need 75mg to 90mg of vitamin daily.

When the body’s store of Vitamin C is depleted, the individual begins to experience problems.
