Vitamin D linked with improved lung function in COPD patients: UK Biobank
A study published in BMJ Open Respiratory Research found that higher concentrations of vitamin D, specifically serum 25-hydroxyvitamin D (25(OH)D), are associated with improved survival in individuals with chronic obstructive pulmonary disease (COPD). The UK Biobank, including 403,648 participants, showed that COPD survival increased with higher 25(OH)D concentrations. The lowest risk of COPD incidence was found in participants with concentrations at 55 nmol/L. The optimal concentrations associated with lower COPD risk were 50 to 60 nmol/L. Further research is needed to investigate the causal or contributory role of lower concentrations of 25(OH)D in COPD risk.
