Vitamin C and the common cold

In the 1970s, Linus Pauling argued that vitamin C could significantly decrease the incidence of the common cold, which spurred a widespread belief that consuming more vitamin C will reduce the risk of catching a cold and reduce its severity.[1] The common cold is caused by several strains of viruses including the rhinovirus and the coronavirus. Colds are the leading cause of doctor's visits and the number one reason for absences from work and school. Symptoms include nasal discharge, difficulty breathing through the nose, swelling of the sinus membrane, sneezing, sore throat, cough, headache and a slight fever. Unfortunately however, vitamin C does little to prevent the common cold or decrease the severity of symptoms.[2]
