Targeting delivery to the lungs: Inhaled vitamin D could be new strategy

Article excerpt

People with chronic lung diseases like COPD, asthma, and cystic fibrosis often have low vitamin D levels, a deficiency linked to worsening respiratory outcomes. Researchers have explored vitamin D supplements as a potential treatment, but oral pills may not deliver the nutrient efficiently to damaged lungs. A new approach involves inhaling vitamin D directly to the respiratory system, potentially offering better targeting and therapeutic benefit for patients whose lung tissue is already compromised.
