Vitamins 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 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.

Some conditions may increase your need for vitamin C. These include:

• AIDS (acquired immune deficiency syndrome)
• Alcoholism
• Burns
• Cancer
• Diarrhea (prolonged)
• Fever (prolonged)
• Infection (prolonged)
• Intestinal diseases
• Overactive thyroid (hyperthyroidism)
• Stomach ulcer
• Stress (continuing)
• Surgical removal of stomach
• Tuberculosis

Also, the following groups of people may have a deficiency of vitamin C:

• Infants receiving unfortified formulas
• Smokers
• Patients using an artificial kidney (on hemodialysis)
• Patients who undergo surgery
• Individuals who are exposed to long periods of cold temperatures

Increased need for vitamin C should be determined by your health care professional.

Vitamin C may be used for other conditions as determined by your health care professional.

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 used 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.
