It’s cold season, which has many of us reaching for our Vitamin C. But, the jury’s still out on whether taking large doses of the vitamin really has an effect on the common cold. Tests have shown that adults who take 1g of Vitamin C daily will reduce the duration of their colds by 8 percent, meaning that over the course of a year, an adult might save a day of being down with the sniffles. Greater impact was found on those who took 1-3g of the vitamin before strenuous exercise, like running a marathon. Those people reduced their incidence of colds by half.
