A common vitamin may treat damaged lungs when inhaled. 


Swallowing vitamin D pills has failed to help patients with chronic lung diseases — but a groundbreaking new approach suggests inhaling the vitamin directly into the lungs could bypass the body's natural barriers and finally deliver relief.

 For years, clinical trials testing oral vitamin D supplements in patients with chronic obstructive pulmonary disease (COPD), asthma, and cystic fibrosis have consistently failed to show meaningful improvements in lung function or quality of life.  Now, researchers at the University of North Carolina School of Medicine and the COPD Foundation believe they have discovered why.

 When vitamin D is swallowed, it enters the bloodstream and makes its way to the lungs. There, an enzyme in the blood vessels of the lungs likely deactivates the vitamin before it can reach the tissues of the airways that require it the most. This enzymatic barrier explains why simply raising vitamin D levels in the blood does not translate to better respiratory health.

 To overcome this obstacle, scientists are proposing a shift toward delivering vitamin D directly into the airways via inhalation or nebulization.  While preclinical animal and cellular models indicate that inhaled vitamin D can protect airway linings, reduce inflammation, and defend against environmental pathogens, researchers emphasize that human trials are still needed to establish safety and proper dosing.

 With over 30 million Americans currently living with COPD, this innovative and targeted respiratory strategy could ultimately revolutionize how we protect damaged lungs.
