Increasing your intake of Vitamin C during common cold may significantly help in reducing the duration of the viral infection, says a new study. The findings showed that people who consumed larger doses of Vitamin C, six-eight grams per day, during their cold helped them reduce its duration. Vitamin C is also rich in food such as bell peppers, dark leafy greens, kiwi fruit, broccoli, berries, citrus fruits, tomatoes, peas, and papayas. Vitamin C administration does not decrease the average incidence of colds in the general population, yet it halved the number of colds in physically active people, the researchers said. “Given the consistent effect of Vitamin C on the duration of colds, and its safety and low cost, it would be worthwhile for individual common cold patients to test whether therapeutic eight gram per day Vitamin C is beneficial for them,” said Harri Hemila from the University of Helsinki, Finland. “Self-dosing of Vitamin C must be started as soon as possible after the onset of common cold symptoms to be most effective.” Hemila added, in the paper published in the journal Nutrients. Various animal studies have found that Vitamin C significantly prevents and alleviates infections caused by diverse bacteria, viruses, and protozoa. However, the practical importance of Vitamin C in human infections was not yet known.For the study, the team analysed two randomised trials which investigated the effects of two Vitamin C doses on the duration of the common cold.
