Low Levels Vitamin D makes Asthma Worse

In an article published in the American Journal of Respiratory and Critical Care Medicine, researchers from National Jewish Health, have associated low levels of Vitamin D with more severe asthma. The study measured patients’ levels of hyper-responsiveness, which measures the air passages’ tendency to constrict, leading to breathing difficulty. Hyper-responsiveness was twice as high in people with low vitamin D levels. Also in patients with levels below 30, lung function was worse and they had less response to steroid therapy.
