  • Improved Exercise-Induced Bronchoconstriction Lung Function

  • High evidence
  • Clinical

  Studies in exercise-induced bronchoconstriction suggested some improvement in lung function measures with vitamin C supplementation, but theses studies were few and very small, with limited data and we judged the quality of the evidence to be low.
