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 influenza12 as well as asthma342 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).
