(NaturalNews) Asthmatics with low levels of vitamin D may suffer more severely from the disease than patients with sufficient levels of the vitamin, according to a study conducted by researchers from National Jewish Health in Denver and published in the American Journal of Respiratory and Critical Care Medicine.
“Our findings suggest that low vitamin D levels are associated with worse asthma,” lead researcher E. Rand Sutherland said.
The researchers measured the vitamin D blood levels of 54 asthma patients, along with their lung function, airway hyper-responsiveness and response to steroid drug treatment.
Airway hyper-responsiveness measures the air passages’ tendency to constrict, leading to breathing difficulty.
