Can Vitamin C Treat The Common Cold?
Many people believe that vitamin C can cure a common cold, but research has not confirmed this. However, large doses of vitamin C may protect people who are exposed to severe physical activity and cold temperatures.
People with low vitamin C, because of smoking or older age, for example, may find supplements beneficial.
Other benefits of Vitamin C may include the following:
Cardiovascular health: Vitamin C may widen the blood vessels, and this could help protect against heart disease and hypertension, or high blood pressure.
Cholesterol levels: These were found to be lower in individuals with adequate levels of vitamin C.
Cataracts: Vitamin C may help lower the risk of cataracts as well as of age-related macular degeneration.
Diabetes: Patients are less likely to experience deterioration of the kidneys, eyes, and nerves if they eat plenty of fruit and vegetables that are rich in vitamin C.
Anemia: Vitamin C enhances the absorption of iron.
Lead levels may be reduced if there is an adequate intake of vitamin C.
Histamine: Histamine is a substance the immune system produces, resulting in inflammation and other problems. A 1992 study found lower blood levels of histamine in people who took 2 grams (g) of vitamin C per day.
Seasickness: In a study of 70 people who took either 2 g of vitamin C or a placebo and then spent 20 minutes on a life raft in a wave pool, those who took the supplement had reduced levels of seasickness.
