Vitamin D

Recent evidence suggests that supplementation with Vitamin D3 in asthmatic adults who are deficient or have insufficient levels of vitamin D may result in better asthma control, this is increasingly important as we come into mould season ( a known immunosuppressant).

The relationship between asthma and vitamin D deficiency has been known for some time. Several studies in adults and children indicate that low vitamin D levels are associated with poorer asthma control, poorer lung function, decreased response to glucocorticoids and more frequent exacerbations of symptoms. 

This trial included 112 adults with asthma and serum 25-hydroxyvitamin-D3 levels below 74.9 nmol/L (reference range 50 – 140 nmol/L). Participants were randomised to receive either oral supplements with 16,000 IU of calcifediol (25-hydroxyvitamin D3) per week or a placebo, in addition to usual asthma treatment. Scores on the asthma control test (ACT) were used to measure the effects of supplementation. At baseline, mean ACT scores were 17.71 in the intervention group and 19.02 in the control group. After six months, mean ACT scores were 20.49 in the intervention group and 18.23 in the control group. There was also a significant improvement seen in the quality of life in the intervention group compared to the control group.

The research indicates that monitoring for, and correcting vitamin D deficiency can decrease inflammation and improve response to treatment with inhaled corticosteroids thereby improving asthma control. If you or someone you know suffers from asthma we advise testing vitamin D status to promote optimal lung health. 

We have many options available via compound or practitioner only vitamin D at TCPA. If you are concerned about your vitamin D status or would like to trial some to support your immunity this autumn, please speak to our qualified team.
