Growing research worldwide suggests that vitamin A(VA) plays an important role in asthma.vitamin A deficiency (VAD) could be commonly found in children with asthma.The lower the serum VA concentration is, the more severe the asthma is.In animal experiments, VAD could promote asthma occurrence as well as exacerbation, via regulating T cell function, maintaining airway epithelium integrity, promoting the normal development of lung,antioxidation and so on.However,the effect of vitamin A supplement on asthma is still controversial.
