Vitamin C is also called ascorbic acid and ascorbate. It has many benefits. Vitamin C is an antioxidant. This means that it fights cell damage in your body. Damaged cells raise your risk for cancer and heart disease. Vitamin C may help you resist these diseases. But does it help cure the common cold? So far, there is no evidence that taking vitamin C truly helps cure colds.
