Surviving Cold Season
Story Updated: Oct 4, 2012
Your mother always swore by Vitamin C to combat a cold...but how about Vitamin D?
Researchers in New Zealand recently put it to the test with the help of 322 healthy adult participants. Each was randomly assigned to receive either a high monthly dose of Vitamin D or a placebo.
During the 18-month study, there were 593 upper respiratory infections reported in the Vitamin D group. While 611 colds were reported in the placebo group.
An upper respiratory infection in our study was defined as having one of more of the following symptoms which I think everyone would
be familiar with, nasal stuffiness, runny nose, sore
throat, a cough, with the person telling us that it
was not due to their allergies if they had them.Ó
With numbers that close, taking Vitamin D was seen as having no clinical impact against getting a bad cold...or how long it lasted.
So while low Vitamin D levels have been associated with an increased risk of respiratory infections...this small study indicates Vitamin D supplements are no match for the common cold.
The complete study can be found in the Journal of the American Medical Association.
