A unique omega-3 supplement derived from the New Zealand green-lipped mussel improved lung function and reduced inflammation in asthmatics, researchers say. Timothy Mickleborough, a professor in the Indiana University School of Public Health - Bloomington, said the study, published online in the journal Respiratory Medicine, found a 59 percent improvement in lung function after taking a lung test. Eight women and 12 men ages 20-24 took part in the study. None took daily maintenance medication but all used rescue inhalers. They followed their regular diet for three weeks, after which half took a placebo for three weeks while the rest took the supplement. They then followed their normal diet for two weeks. After that, they took the alternative supplement for three weeks, Mickleborough said. "Not only does the supplement reduce symptoms, which will make you feel better, but it potentially could improve athletic performance," Mickleborough said in a statement. "Any time you can reduce medication is good."
