Vitamin C and E for asthma and exercise-induced bronchoconstriction

  • Protocol
  • Intervention



This is the protocol for a review and there is no abstract. The objectives are as follows:

To assess the effects of vitamin C and E supplementation on exacerbations and health-related quality of life (HRQL) in adults and children with chronic asthma compared to placebo (or no vitamin C and E supplementation). We will also examine the potential effects of Vitamin C and E on exercise-induced bronchoconstriction, in people with asthma and people without a diagnosis of asthma who only experience symptoms on exercise.
