Disease prevention and therapeutic use

Dozens of prospective studies suggest that vitamin C plays a role in preventing a variety of diseases, such as a common cold. They do demonstrate a moderate benefit in terms of the duration and severity of episodes in some groups, especially those who are exposed to substantial physical and/or cold stress.

Wound Healing

During a postoperative period or while healing superficial wounds, supplemental vitamin C contributes to the prevention of infections and promotes repair of the skin.

Cardiovascular diseases - heart disease and stroke

Vitamin C may protect coronary arteries by reducing formation of plaque, as it helps to prevent the oxidation of LDL cholesterol (the ‘bad’ cholesterol), especially in combination with vitamin E. Some data also showed that vitamin C may boost blood levels of HDL cholesterol (the ‘good’ cholesterol), which is also considered positive for the prevention of heart diseases.

The risk of stroke may be reduced by an adequate intake of vitamin C through fruits, vegetables and supplements. However, due to the inconsistency of the data and lack of specificity to vitamin C, the interpretation of these results is difficult.

Blood Pressure

Several studies have shown a blood-pressure lowering effect of vitamin C supplementation of about 500 mg vitamin C per day because it improves the dilation of blood vessels.

Cancer

A number of studies were able to associate higher intakes of vitamin C with decreased incidence of cancers of the upper digestive tract, cervix, ovary, bladder, and colon. Five servings of most fruits and vegetables provide more than 200 mg vitamin C per day. Just statistically significant reductions in risk of cancer were found in people consuming at least 80 to 110 mg of vitamin C daily.
