Had chronic bronchitis for 11 years. Every winter I’d end up on antibiotics and still couldn’t shake the mucus. My doctor kept saying ‘manage it.’ Watched the video, started BREATHIZEN. Week 2 the morning congestion started clearing. Week 6 I slept through the night without coughing for the first time in years. I wish I’d found this sooner.

COPD diagnosis 3 years ago. Nights were the worst — woke up 3, 4 times gasping. Started BREATHIZEN after watching the presentation. By week 4, sleeping 6 hours straight. My oxygen levels are more stable and my pulmonologist actually asked what I changed.

Margaret S., 72​

Nashville, TN

Bronchitis twice a year, every year, for the past decade. Each round left my lungs a little worse. After the video I understood why — the inflammation never fully cleared. Started BREATHIZEN, and this is the first winter in 10 years I haven’t ended up in urgent care.
