A Study to Evaluate the Effects of a Supplement on Mucus Clearance and Respiratory Symptoms

This is a randomized, triple-blind, placebo-controlled clinical trial evaluating the effects of the BetterLungs Mullein + Chlorophyll supplement on mucus clearance and respiratory symptoms over 60 days. One hundred adult participants experiencing chest mucus build-up, difficulty clearing mucus, breathlessness, and low energy levels will be enrolled and randomized to either the active supplement or a matched placebo. Participants will take their assigned product once daily in the morning mixed with water and will complete self-reported questionnaires at Baseline, Day 20, Day 40, and Day 60.
