Lower level of vitamin D are associated with death from all causes.
By Stephen W. Parcell, ND
According to a recent study on Japanese individuals lower serum 1,25(OH)2D levels are a potential risk factor for all-cause death, especially cardiovascular and respiratory infection death, in the general Japanese population, and that lower serum 1,25(OH)2D levels greatly increase the risk of respiratory infection death in subjects with kidney dysfunction. Other studies on different population all indicate the same thing.
