Decongestant
Mainly used as relief from winter bugs, NAC helps to break down thick mucus and congestion from the nose and airways. It is used medically to help people with everything from blocked noses and inner ears, to serious lung diseases. 

Antioxidant Support
NAC is widely valued for helping the body produce glutathione, one of the most important antioxidants involved in cellular defence.

Workout Support
As an amino acid, NAC is also popular nowadays as a gym supplement. In research, it’s been found to enhance muscle cysteine and glutathione availability, and reduce fatigue during prolonged exercise in endurance-training. 

Powerful Detox
NAC is used as a detox supplement that supports the body’s natural processes for clearing out toxins, including alcohol and certain medicines. In clinical settings it is sometimes used to treat overdoses. 

Hangover Prevention
Our bodies process alcohol by converting it into acetaldehyde - which is toxic. We need plenty of NAC to produce enzymes (in particular ADH and ALDH) that clear out acetaldehyde. When we run out of NAC, the build-up of acetaldehyde causes hangovers - which is why a NAC supplement the night before and the morning after can work wonders!
