Research: VAN STRATEN and JOSLIN

Listed in Issue 83

Abstract

VAN STRATEN and JOSLING, Herbal Health Centre, Battle, East Sussex, UK, conducted a double-blinded, placebo-controlled survey of the preventive effect of a vitamin C supplement on the common cold .

Background

Anecdotal evidence of vitamin C as a cure and/or prevention for colds has been well-known to the general public since Linus Pauling popularized his own experience.

Methodology

168 volunteers were randomized to receive 2 daily vitamin C tablets of unspecified dose or 2 placebo tablets over the period from November to February . They filled in daily protocols of their health on a five-point scale and recorded incidences of colds .

Results

Subjects in the experimental group had fewer colds (p = 0.05), fewer days 'challenged virally' and shorter duration of symptoms (1.8 vs. 3.1 days, p = 0.03). Few side effects occurred with the active treatment.

Conclusion

The vitamin C preparation tested here (about which we are not informed) appears to be effective in the prevention and treatment of common colds and well received by the test subjects.
