Washington: Some data have suggested a possible inverse association between serum vitamin D levels and the incidence of upper respiratory tract infection, but a new study found that a monthly dose of 100,000 IU of vitamin D3 in healthy adults did not significantly reduce the incidence or severity of colds.The association of vitamin D insufficiency and susceptibility to viral respiratory tract infections has been unclear, according to background information in the article.David R. Murdoch, M.D., of the University of Otago, Christchurch, New Zealand, and colleagues conducted a randomized trial to examine the effect of vitamin D supplementation on incidence and severity of upper respiratory tract infections (URTIs) in healthy adults.The study, conducted between February 2010 and November 2011, included 322 healthy adults in New Zealand. Participants were randomly assigned to receive an initial dose of 200,000 IU oral vitamin D3, then 200,000 IU one month later, then 100,000 IU monthly (n = 161), or placebo administered in an identical dosing regimen (n = 161), for a total of 18 months.
