Newswise — Vitamin D may help reduce the incidence and severity of viral respiratory tract infections including influenza, according to a new study conducted by investigators at Greenwich Hospital and Yale University School of Medicine.
The study, led by James R. Sabetta, M.D., followed 198 healthy adults during the fall and winter 2009-2010. The rationale for the study was to determine if the declining concentrations of vitamin D seen in the fall and winter in a temperate climate could be a factor in the seasonal increased prevalence of respiratory viral infections such as the flu.
