Vitamin C may reduce may reduce bronchoconstriction and respiratory symptoms after exercise, according to a Swedish study.

The meta-analysis of available studies on vitamin C published recently in Allergy, Asthma and Clinical  Immunology looked at the effects of vitamin C on subjects with respiratory problems after exercise (exercise-induced bronchoconstriction). The meta-analysis of three studies showed that vitamin C reduced post-exercise FEV1 (standard pulmonary function outcome used for assessing if a person suffers from exercise-induced bronchoconstriction) in participants. Five other analysed studies looked at people under a short-term physical stress and the results suggested that vitamin C halved the incidence or respiratory symptoms.
