Vitamin C is necessary for normal growth and development. Vitamin C is required for the growth and repair of tissues in all parts of your body. It is necessary to form collagen, an important protein used to make skin, scar tissue, tendons, ligaments, and blood vessels. Vitamin C is essential for the healing of wounds, and for the repair and maintenance of cartilage, bones, and teeth.

Vitamin C is one of many antioxidants. Vitamin E and beta-carotene are two other well-known antioxidants. Antioxidants are nutrients that block some of the damage caused by free radicals, which are by-products that result when our bodies transform food into energy.

The build up of these by-products over time is largely responsible for the aging process and can contribute to the development of various health conditions such as cancer, heart disease, and a host of inflammatory conditions like arthritis. Antioxidants also help reduce the damage to the body caused by toxic chemicals and pollutants such as cigarette smoke.

The body does not manufacture vitamin C on its own, nor does it store it. It is therefore important to include plenty of vitamin C-containing foods in your daily diet.

There is C vitamin in almost every fruit and vegetable but some have far higher C vitamin content than others. Cranberries and melons have high C vitamin content. In fact, tropical fruits have the highest C vitamin amounts of all fruit. Hot peppers are amongst the richest sources of the c vitamin when it comes to vegetables. The hotter the pepper, the higher its C vitamin content is.

Unfortunately, the C vitamin is water soluble so many vegetables lose their effectiveness as a c vitamin provider if they are boiled for a long time. Steaming or quick stir frying vegetables ensures that more of their C vitamin content is retained. The recommended daily amount of the C vitamin is easily obtained from eating five portions of fruit and vegetables a day if they are consumed raw or cooked quickly.

Vitamin C toxicity is very rare, because the body cannot store the vitamin. However, amounts greater than 2,000 mg/day are not recommended because such high doses can lead to stomach upset and diarrhea.

Too little vitamin C can lead to signs and symptoms of deficiency, including:

• Dry and splitting hair
• Gingivitis (inflammation of the gums)
• Bleeding gums
• Rough, dry, scaly skin
• Decreased wound-healing rate
• Easy bruising
• Nosebleeds
• Weakened tooth enamel
• Swollen and painful joints
• Anemia
• Decreased ability to fight infection
• Possible weight gain because of slowed metabolism

A severe form of vitamin C deficiency is known as scurvy, which mainly affects older, malnourished adults.
