Vitamin A and D Linked to Improved Lung Function in Asthma Patients, Study Finds

Researchers at Brigham and Women's Hospital in Boston published findings in the journal Thorax on June 30. The analysis included two cohorts: 1,165 children and 1,041 adults with asthma. Participants with higher serum vitamin A concentrations demonstrated superior pulmonary function across both age groups. In contrast, elevated vitamin D levels were associated with improved lung function only among adult asthma patients. These results suggest a potential role for vitamin A supplementation in managing asthma-related respiratory impairment, while the benefit of vitamin D may be limited to adult populations.
