N-Acetyl Cysteine (NAC) is a precursor for the amino acid L-cysteine which when taken orally can cause the body to produce more of the potent antioxidant glutathione that it otherwise would. By raising glutathione levels NAC provides antioxidant effects and similar benefits to taking bioavailable glutathione supplements.In addition to its ability to raise the body’s production of glutathione, NAC also supports healthy liver, lung, and kidney function and may support healthy immune system functioning.

N-Acetyl Cysteine is very well tolerated and side effects are unlikely at normal doses, but when taken at high doses side effects such as nausea, vomiting, diarrhea, and constipation are sometimes experienced.

NAC may be dangerous for people with bleeding disorders or taking blood thinning medications as it may slow blood clotting. We recommend avoiding NAC if you’re taking blood thinners or have any bleeding disorders such as hemophilia.
