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
Some conditions may increase your need for vitamin C. These include:
AIDS (acquired immune deficiency syndrome)
Overactive thyroid (hyperthyroidism)
Surgical removal of stomach
Also, the following groups of people may have a deficiency of vitamin C:
Infants receiving unfortified formulas
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
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.
Vitamin C is available in the following dosage forms:
Extended-release capsules (U.S.)
Oral solution (U.S.)
Tablets (U.S. and Canada)
Chewable tablets (U.S. and Canada)
Effervescent tablets (U.S.)

Importance of Diet
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 cannot work without
the presence of other foods.
The daily amount of vitamin C needed is defined in several different ways.
For U.S. -
Recommended Dietary Allowances (RDAs) are the amount of vitamins
and minerals needed to provide for adequate nutrition in most healthy persons.
RDAs for a given nutrient may vary depending on a person's age, sex, and physical
condition (e.g., pregnancy).
Daily Values (DVs) are used on food and dietary supplement labels
to indicate the percent of the recommended daily amount of each nutrient that
a serving provides. DV replaces the previous designation of United States
Recommended Daily Allowances (USRDAs).
For Canada -
Recommended Nutrient Intakes (RNIs) are used to determine the amounts
of vitamins, minerals, and protein needed to provide adequate nutrition and
lessen the risk of chronic disease.
Normal daily recommended intakes for vitamin C are generally defined as
Birth to 3 years of age
| 4 to 6 years of age
|7 to 10 years of age
|Adolescent and adult
|Adolescent and adult females
