N-Acetyl-Cysteine (NAC) is a stable and bioactive form of L-Cysteine, an amino acid that plays a key role in phase II detoxification and homocysteine metabolism. NAC is efficiently transported into the cell, where it is readily converted to cysteine for glutathione synthesis and regeneration.
Because NAC can penetrate the blood-brain-barrier, it is especially important for maintaining healthy brain and nervous system tissues.*
NAC also helps to support respiratory health by promoting normal mucus viscosity.*
