In a clinical trial, researchers at Tanta University in Egypt and the University of Helsinki in Finland determined when and under what conditions children may benefit the most from a daily dose of vitamin C.
The scientists tested their theories on a group of 70 kids who were 7 to 10 years old. The volunteers took 0.2-gram supplements of vitamin C daily, and study investigators measured the children’s forced expiratory volume per one second (FEV1) to determine what effect the antioxidant had on their asthma symptoms. Results of this study suggest that asthmatic children may benefit from a natural nutritional supplement that contains vitamin C.
In participants who were 7 to 8.2 years old and had no exposure to mold or damp rooms, FEV1 was increased by 37 percent. In the older subset, 8.3 to 10 years old, those who were exposed to fungi and dampness experienced a 21 percent improvement in FEV1.
When looking only at the age of the volunteers, the researchers still observed a more significant effect of vitamin C in the younger group.
