A closer look: "Vitamin D no match for common cold"
October 4, 2012 -- John Cannell, MD
Many of readers report a reduction (not absence) of colds and flu with 5,000 IU daily doses of vitamin D. However, hundreds of media outlets are reporting on a well-conducted JAMA study that showed no benefit for vitamin D in preventing the common cold.
  • Vitamin D Won’t Save You From Common Cold, Latest Study Says

  • Vitamin D doesn’t fight off colds
The randomized controlled trial, led by Dr David R Murdock of the University of Otago in New Zealand, found that 200, 000 IU per month for two months followed by 100,000 IU per month of vitamin D for 16 months in 161 patients did not prevent either the diagnosis or complaint of the common cold. The study included viral cultures, rigorous efforts to capture all infections, vitamin D given during monthly doctor visits, and initial and follow up vitamin D levels. The average initial level in the treatment group was 29 ng/ml and 18 months later, the mean level was approximately 50 ng/ml, with no side effects.

However, only 13 of the 161 placebo patients had levels below 20 ng/ml and only 5 of the 322 total patients had levels less than 10 ng/ml to begin the study. That is, the placebo group had relatively high levels (mean of 28 ng/ml initially), compared to most populations, and all but 13 patients had levels above 20 ng/ml for most of the study, apparently from sun exposure.
