Coenzyme Q10 (CoQ10) plays a central role in mitochondrial energy production, and it's particularly concentrated in high-oxygen-demand tissues like the heart and lungs.
Research links CoQ10 supplementation to improved exercise tolerance and reduced fatigue in some populations — outcomes that translate to easier breathing during activity rather than a direct lung-tissue effect.
It's one of the better-researched ingredients in this formula, though again without a disclosed per-capsule amount.
Where it sits in the formula: part of Lungora's Circulation & Cellular Energy category, alongside Butcher's Broom Root Extract, L-Carnitine.
