What is NAC?

Let us break it down for you. N-Acetyl-L-Cysteine, or NAC for short, is a form of cysteine, an amino acid that acts as a sulfur donor and plays a part in the synthesis of glutathione. NAC supplements can help maintain and support wellness in multiple ways:

Immune Support: NAC provides a source of the amino acid that helps synthesize glutathione, a compound needed for a healthy immune system.
Antioxidant Action: Glutathione also works as an antioxidant, helping prevent cellular damage caused by free radicals and the environment.
Cellular Health: NAC is associated with cellular detox, which may help support health throughout the body.
