(New York, Reuters Health, 9/26/02)

Dr. Isabelle Romieu of the National Institute of Public Health in Mexico and colleagues randomly divided 158 asthmatic children into 2 groups. Participants in one group took a daily vitamin supplement; while the others were given a placebo. After a year and a half, the children receiving the vitamins had better lung function than their peers, as demonstrated by measuring forced expiratory flow and peak expiratory volume.
