Product Overview


  • Dietary Supplement
  • Antioxidant Support

N-Acetyl cysteine is a stable form of the sulfur amino acid L-cysteine, and is a powerful antioxidant. It is also a precursor of glutathione, a major antioxidant. Glutathione is activated by the selenium-containing glutathione peroxidase, one of the most important antioxidant enzymes in the body. N-Acetyl cysteine is better than glutathione supplements, which may break down during digestion and lose potency.

Suggested Use

1 to 2 tablets daily.

Other Ingredients

Dibasic calcium phosphate, stearic acid, modified cellulose gum, colloidal silicon dioxide, and magnesium stearate.

Hypoallergenic: Contains no yeast, dairy, egg, gluten, corn, soy or wheat. Contains no sugar, starch, salt, preservatives, or artificial color, flavor or fragrance.

Good product: seems to be working

I take this for unipolar depression instead of taking prescribed medication

Thanks for your feedback!

Product impressions

Posted by iHerb Customer on Jun 03, 2017 | Verified Purchase

The tablet was larger than expected but it was easy to take. Because the number of days after ingestion is small, the effect has not been realized yet. I will continue taking doses and look at the situation. Thank you very much.

Thanks for your feedback!

Part of a candida cleanse routine

N-Acetyl Cystine: Effective. Using as part of a candida cleanse routine recommended by "Cooking For Balance". It does take time to get your body back in balance. Be patient.

Thanks for your feedback!

Nice product

Posted by iHerb Customer on Mar 10, 2017 | Verified Purchase

My Dr. makes me take this - I know it's offering a benefit to my body but not one I physically see or feel which is fine as long as it is doing what it is supposed to.

Thanks for your feedback!
