We analysed self‐reported cold data for 95 pairs of identical twins who took part in a double‐blind trial of vitamin C tablets. One member of each twin pair took vitamin C and the other took a well matched placebo each day for 100 days. Vitamin C had no significant effect except for shortening the average duration of cold episodes by 19%.
