AsthmaTreatment

The beneficial effects of vitamin D for those with asthma appear to be primarily reduced risk of respiratory viral infections and effects on cytokine production, thus affecting inflammation.

Based on results of influenza1 2 as well as asthma3 4 2 studies, it seems that children should take at least 1200–2000 IU/day of vitamin D3 and try to achieve serum 25(OH)D levels above 38 ng/mL (95 nmol/L).
