Vitamin C
Vitamin C is a water-soluble vitamin. It is needed for normal growth and development.
Water-soluble vitamins dissolve in water. Leftover amounts of the vitamin leave the body through the urine. Although the body keeps a small reserve of these vitamins, they have to be taken regularly to prevent a shortage in the body.
Function
Vitamin C is needed for the growth and repair of tissues in all parts of your body. It is used to:
Form an important protein used to make skin, tendons, ligaments, and blood vessels
Heal wounds and form scar tissue
Repair and maintain cartilage, bones, and teeth
Aid in the absorption of iron
Vitamin C is one of many antioxidants. Antioxidants are nutrients that block some of the damage caused by free radicals.
Free radicals are made when your body breaks down food or when you are exposed to tobacco smoke or radiation.
The buildup of free radicals over time is largely responsible for the aging process.
Free radicals may play a role in cancer, heart disease, and conditions like arthritis.
The body is not able to make vitamin C on its own. It does not store vitamin C. It is therefore important to include plenty of vitamin C-containing foods in your daily diet.
For many years, vitamin C has been a popular household remedy for the common cold.
Research shows that for most people, vitamin C supplements or vitamin C-rich foods do not reduce the risk of getting the common cold.
However, people who take vitamin C supplements regularly might have slightly shorter colds or somewhat milder symptoms.
Taking a vitamin C supplement after a cold starts does not appear to be helpful.
