Vitamin D has a profound, systemic effect on all areas of health. It circulates around the body and is involved in cell-signalling which can influence everything from bone health to muscle function.

In this study examining the relationship between serum vitamin D levels and airway structure and function in 86 children, severely asthmatic children were found to have lower vitamin D levels than either moderate asthmatics or non-asthmatics.

In these children (average age 11.7 years), higher vitamin D levels correlated with reduced airway inflammation and improved airway structure and lung function.

The results suggest that vitamin D supplementation may be useful in treating asthma. However, many health problems are either caused or made worse by excessive inflammation, meaning that vitamin has a role in supporting all areas of health.
