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.


Keep tightly closed in a cool, dry place.

Do not use if you are taking any form of prescription nitrate such as nitroglycerin. If you are pregnant, may become pregnant, or breastfeeding, consult your health care professional before using this product.

Easy to swallow tablets. Only been on for less than 8 weeks.

Too early to tell

Posted by 5693580305384162443 on Aug 21, 2014

I am using this product as a supplement for my prescription psych. pills. It takes 2-3 wks to tolerate it, I have had no problems but 2-3 months to see if it works, far too early to tell but I hold hope. I will buy again from your site and run a 2nd course through. Your postage, price were both excellent. Thank you

Tried Source Natural's after Google'ing brands that pushed out quality multi vitamins. Source Naturals was a brand that was ranked higher than Jarrow's, but I think quality and potency differs for specific supplements. I found the Jarrow's Sustained NAC a better formula than Source Naturals.
