Background: Asthma is a common and major allergic disease in the world. We aimed to investigate the impact of supplements with vitamin D, folic acid, selenium, zinc, and copper in patients with moderate to severe asthma.

Method: In this clinical trial study 70 patients above six years old with moderate to severe asthma, were divided into two groups, randomly; one group received daily Asmavit syrup, 10 ml (Asmavit, Vitabiotics Ltd, London, UK), and the other group received daily 1000 IU vitamin D3 drops (Asmavit, Vitabiotics Ltd, London, UK) for two months along with ordinary treatment for asthma. Clinical and physical examinations, immunological and biochemical tests were carried out for each patient before and after the treatment.

Results: The mean age of patients was 39.9± 14.7 years old, and the mean disease duration was 8.8 ± 9.8 years. A significant increase in lung function, asthma control, and quality of life score tests was observed in both groups after the treatment (P< 0.05). There was no significant difference in cytokines expression levels before and after the treatment with vitamin D3 or Asmavit (P> 0.05). Serum levels of selenium and folic acid before treatment were correlated with disease severity, while post-treatment vitamin D levels significantly increased FEV1 (P> 0.05). Oxidative stress levels reduced in both groups, with greater reduction in the vitamin D group (P< 0.05).

Conclusion: Supplements, particularly vitamin D, when combined with standard asthma treatment, may effectively improve clinical symptoms and enhance the quality of life for asthmatic patients.
