NAC is one of the more established supplements in the wellness space. It's the building block your body uses to make glutathione, its main internal antioxidant, and it has a long track record for supporting liver health and clearing mucus from the airways. Bucked Up keeps it simple: 600mg of NAC in one capsule, with nothing else added.*
At 600mg, this is a solid daily starting dose and in line with what's commonly used for general antioxidant and respiratory support. Some research uses higher amounts, often 1,200mg or more spread across the day, so this is a foundational dose rather than a high one. If you're considering more, it's worth talking to your healthcare provider first.*
A couple of practical notes. NAC naturally contains sulfur, so a slight rotten-egg smell when you open the bottle is normal and doesn't mean anything is wrong. And while antioxidants are great for overall health, some research suggests that very high antioxidant intake right around workouts may slightly blunt certain training adaptations, so taking NAC at a different time of day than your training is a reasonable approach. If you take prescription medications, especially for blood pressure or heart conditions, check with your doctor before adding it.*
