Do any supplements help prevent or treat a cold?

Answer:

Certain supplements can reduce the chance of getting a cold, while others may help reduce the severity of a cold or relieve cold symptoms. Other supplements don't seem to be beneficial for colds, but they may help prevent or treat other types of respiratory infections or inflammation. On the other hand, some supplements that are promoted for preventing or treating colds may not be beneficial.
