Could simple supplements improve lung health in rare disease?

This study tests whether taking glycine and magnesium+thiamine supplements for 6 months can reduce lung infections and improve breathing in people with primary ciliary dyskinesia (PCD), a rare lung condition. About 60 participants aged 5 and older will receive either one or both supplements, or a placebo powder. The goal is to see if these safe, low-cost options can ease symptoms and boost quality of life.
