Other than its use in supplements, NAC has a history of helping with respiratory conditions. This is great news for anyone who has any condition such as asthma or has trouble breathing and needs strong lungs for physical activities.

NAC might give your cellular energy production a boost by improving mitochondrial function. This can lead to better endurance during your workouts, as well as faster recovery both between sets and sessions.
