Later, I added N-acetylcysteine (NAC) as part of my recovery support for respiratory and immune health. NAC is known for helping to break down thick mucus, support lung function, reduce oxidative stress, and assist the body in detoxifying inflammatory byproducts associated with infections. Over time, I noticed that my chest congestion became easier to manage, my breathing felt smoother, and my resistance to repeated infections improved. My body no longer felt trapped in a constant cycle of mucus production, toxic buildup, and respiratory strain caused by medication effects and environmental viral exposure.
