N-Acetyl Cysteine
N-acetyl cysteine is a precursor to glutathione
N-acetyl cysteine (NAC) is an amino acid and a precursor to the production of glutathione, the body’s primary cellular antioxidant. Glutathione’s antioxidant/detoxification properties help fight infections. Glutathione also facilitates the production of several digestive enzymes. NAC has been shown to help reduce levels of fatigue and improve muscle contraction during exhaustive exercise.*
