Vitamin D may help keep viral infections at bay
Serum levels of 25-hydroxyvitamin D correlate with the incidence of viral respiratory tract infections, according to a recent study published by PLoS One. The prospective cohort study measured 25-hydroxyvitamin D concentrations in 195 healthy adults monthly during the fall and winter of 2009-10. Concentrations of 38 nanograms per milliliter or more were associated with a significant (P<0.0001) twofold reduction in acute respiratory tract infections as well as a reduction in the percentage of days ill. Light skin, lean body mass, and vitamin D supplementation were found to correlate with higher levels of 25-hydroxyvitamin D.
