Vitamins - VYE-ta-mins are compounds that you must have for growth and health. They are needed in small amounts only and are usually available in the foods that you eat. Ascorbic - a-SKOR-bik acid, also known as vitamin C, is necessary for wound healing. It is needed for many functions in the body, including helping the body use carbohydrates, fats and protein. Vitamin C also strengthens blood vessel walls.
Lack of vitamin C can lead to a condition called scurvy, which causes muscle weakness, swollen and bleeding gums, loss of teeth and bleeding under the skin, as well as tiredness and depression. Wounds also do not heal easily. Your health care professional may treat scurvy by prescribing vitamin C for you.

Claims that vitamin C is effective for preventing senility and the common cold and for treating asthma, some mental problems, cancer, hardening of the arteries, allergies, eye ulcers, blood clots, gum disease and pressure sores have not been proven. Although vitamin C is being using to reduce the risk of cardiovascular disease and certain types of cancer, there is not enough information to show that these uses are effective.
Injectable vitamin C is given by or under the supervision of a health care professional. Other forms of vitamin C are available without a prescription.

Vitamin C is found in various foods, including citrus fruits - oranges, lemons, grapefruit, green vegetables - peppers, broccoli, cabbage, tomatoes, and potatoes. It is best to eat fresh fruits and vegetables whenever possible since they contain the most vitamins. Food processing may destroy some of the vitamins. For example, exposure to air, drying, salting, or cooking - especially in copper pots, mincing of fresh vegetables, or mashing potatoes may reduce the amount of vitamin C in foods. Freezing does not usually cause loss of vitamin C unless foods are stored for a very long time.
Vitamins alone will not take the place of a good diet and will not provide energy. Your body also needs other substances found in food such as protein, minerals, carbohydrates and fat. Vitamins themselves often can't work without the presence of other foods.
