N-Acetyl Cysteine (NAC) is a stable form of the non-essential amino acid L-Cysteine. It is a sulfur-containing amino acid that acts as a stabilizer for the formation of protein structures, and promotes the formation of glutathione. Glutathione is a powerful free radical scavenging compound that also helps to maintain normal, balanced immune system function. In addition, NAC can help to support healthy brain and neuronal tissues.

Fantastic - finally managing my symtpoms

Posted by iHerb Customer on April 8 2018 | Verified Purchase

I've been trailing 5 different NAC supplements / brands and dose and have found that these are the best for me. Manages both stress related anxiety and nail biting (according to my naturopath, a study found that high doses of NAC over 6 weeks participants stopped biting their nails). I notice that there's a time of day I start biting my nails and realised I needed to add an extra NAC dose - 500mg wasn't enough but these 1000mg do the job nicely.

Thanks for your feedback!
