NAC 600mg

Take 1 capsule between meals

N-Acetyl-L-Cysteine (NAC) is known for diverse clinical uses. NAC supports respiratory and immune health by promoting normal mucus viscosity. When mucus thickens, it can become hard to expel. NAC’s sulfur content allows it to disrupt disulfide bonds, thinning the mucus so that mucus and any trapped foreign particles are more easily expelled from the lungs.
