How Does the Body Benefit From Vitamin C?

Vitamin C may help those with immune systems weakened by stress; may reduce the risk of stroke; reduces complications from colds and flu; and improves skin health, explains WebMD. These benefits to the body were discovered by researcher Dr. Mark Moyad of University of Michigan, who gleaned information from more than 100 studies of vitamin C over a 10-year period.

Although vitamin C does not cure the common cold, it can reduce the chances of getting pneumonia or other lung infections, notes WebMD. Vitamin C also benefits the body when an individual smokes, is an alcoholic or is obese, as these conditions cause vitamin C levels to fall below normal. People with high levels of vitamin C in their blood can have as much as 42 percent lower risk of stroke. A study also found that women between the ages of 40 of 74 with high levels of vitamin C experienced fewer problems with dry skin, fewer wrinkles and skin that looked better overall.

Evidence suggests people with high levels of vitamin C from fruits and vegetables may experience a lower risk of getting certain cancers, according to the National Institutes of Health Office of Dietary Supplements. These cancers include breast, colon and lung cancer. Research does not show the same benefit from taking vitamin C supplements. High vitamin C levels from fruits and vegetables seemingly result in lower risk of cardiovascular disease, and taking vitamin C with other nutrients seems to slow the progression of age-related macular degeneration.
