Safe and inexpensive vitamin C should be administered to those with exercise-induced bronchoconstriction, according to new research out of Finland.
Investigators note that additional research on the topic is warranted, however their systematic review found a 48% reduction in the FEV1 decline caused by exercise in those who consumed the nutrient.
The relative effect of vitamin C administration on FEV1 was analyzed by using linear modeling for two studies that reported full or partial individual-level data.
“Given the safety and low cost of vitamin C, and the positive findings for vitamin C administration in the three EIB studies, it seems reasonable for physically active people to test vitamin C when they have respiratory symptoms such as cough associated with exercise,” the authors wrote.
