Vitamin C and zinc play important roles in nutrition and for the immune system. A relatively recent study was conducted to see if they help with the common cold (1). An overview of the literature was presented in this review study, followed by data from two preliminary double-blind, randomized, placebo-controlled trials. They were conducted with a combination of 1000mg of vitamin C plus 10mg of zinc in patients with the common cold. In both studies, a nonsignificant reduction of rhinorrhea duration was seened. Vitamin C plus zinc was significantly more effective than placebo at reducing rhinorrhea over 5 days of treatment. Symptom relief was quicker and the safety profile of the combination was excellent.
