Summary

This trial investigates whether adding an astaxanthin-based dietary supplement to a standard pulmonary rehabilitation program can improve exercise capacity in people with moderate to very severe COPD. Participants take two capsules of the supplement daily for 8 weeks while completing supervised exercise training 2-3 times per week. The study compares the supplement-plus-rehab group to a group receiving only rehab, measuring changes in the 6-minute walking distance.
