After reviewing 60 years of clinical studies, they found that vitamin C supplements did not make colds shorter or worse. When taken daily, vitamin C can begin to greatly shorten the duration of colds by 8% in adults and 14% in children.
However, according to this study, the average adult who gets a cold 12 days a year will still get about 11 colds a year if he or she takes a high dose of vitamin C every day that year. As for the average child who is sick for about 28 days a year, taking a high dose of vitamin C daily can still be sick for about 24 days.

The most convincing evidence to date comes from a review of 29 randomized trials with more than 11,000 participants. The researchers found that extremely active people, such as marathon runners, skiers, and the military who exercised heavily in subarctic conditions, took at least 200 mg of vitamin C. every day seems to halve the risk of catching a cold. But for the general population, taking a daily vitamin C supplement does not reduce the risk of catching a cold.
