Vitamin c and the common cold book
Vitamin C Offers Little Protection Against Colds, Review Finds -- ScienceDailyUnless you run marathons, you probably won't get much protection from common colds by taking a daily supplemental dose of vitamin C, according to an updated review of 30 studies. Conducted over several decades and including more than 11, people who took daily doses of at least milligrams, the review also shows that vitamin C ascorbic acid does little to reduce the length or severity of a cold, according to the researchers at the Australian National University and the University of Helsinki. However, they found that people exposed to periods of high stress -- such as marathon runners, skiers and soldiers on sub-arctic exercises -- were 50 percent less likely to catch a cold if they took a daily dose of vitamin C. For most people, the benefit of the popular remedy is so slight when it comes to colds that it is not worth the effort or expense, the authors say. The review appears in the latest issue of The Cochrane Library, a publication of The Cochrane Collaboration, an international organization that evaluates medical research.
Excerpts from Vitamin C and the Common Cold by Linus Pauling
The common cold is the most frequent infectious disease in humans, and the average person gets one several times per year. Around , Nobel prize winner Linus Pauling popularized the theory that vitamin C helps treat colds. He published a book about cold prevention using megadoses of vitamin C, or up to 18, mg daily. For comparison, the RDA is 75 mg for women and 90 mg for men. But in the following few decades, multiple randomized controlled studies examined whether the vitamin had any effect on the common cold. An analysis of 29 studies including 11, participants concluded that supplementing with mg or more of vitamin C did not reduce the risk of catching a cold 1. Other studies in adults have found 6—8 grams per day to be effective 2.

Linus Pauling, Ph. He received these awards for chemistry in and for peace in He contributed greatly to the development of chemical theories. His impact on the health marketplace, however, was anything but laudable. Pauling is largely responsible for the widespread misbelief that high doses of vitamin C are effective against colds and other illnesses.
