Does Vitamin C Work for the Common Cold?

Despite common knowledge, most research suggests that vitamin C does not help prevent the common cold or decrease the severity of common cold symptoms. However, some studies have shown that vitamin C may slightly decrease the duration of a cold by a day or two in some people. However, high doses are usually necessary to see such benefits, often high enough to cause bothersome side effects (such as diarrhea, indigestion, or heartburn). Interestingly, dietary intake of vitamin C (through food or beverages, not through supplements) doesn't seem to have much of an effect on the common cold.

Does Vitamin C Work for Scurvy?
