What is N-Acetyl-L-Cysteine?

N-Acetyl-L-Cysteine, also known as "NAC," is a great amino acid that can boost the levels of Glutathione in the body, which provides for a healthier immune system. Glutathione, as a non-essential nutrient, but yet powerful anti-oxidant that helps prevent oxidative cell damage and reduce the damaging effects of environmental toxins, is responsible for maintaining healthy antioxidant levels in the body. Its purpose is activating certain enzymes, and it plays an important role in carbohydrate metabolism as well. With this being said, NAC, a more stable form of L-Cysteine, is one of the best sources to obtain higher Glutathione levels, and to promote better anti-toxin potential to assist in a healthier immune system.*

NAC has very similar results as L-Cysteine due to the Glutathione levels provided, but is more stable because of its acetyl properties (CH3CO) and is produced as more water soluble, as well as said to be more bio-available than L-Cysteine. As mentioned before, NAC is one of the most cost effective ways to intensify Glutathione levels; it is a very valuable peptide, but very expensive when bought as a supplement.

Other aspects to consider: N-Acetyl-L-Cysteine may also benefit prostate and respiratory health.* You may want to pair this with a Vitamin C, which helps keep the glutathione that is produced from the Cysteine in its reduced form so that it can continue acting as an antioxidant.*
