An amino-acid derivative studied for mucus clearance and antioxidant defense.
N-Acetylcysteine (NAC) is a derivative of the amino acid cysteine, well studied for its role in thinning mucus and supporting antioxidant defense in the lungs.
It's one of the more clinically-researched ingredients in BreathEaseX's spray, with a research history specifically tied to respiratory support.
Worth knowing: NAC can interact with blood-thinning medication, so speak with a doctor before use if you take one.
