How it works

  • N-acetyl-cysteine (NAC) is an amino acid that is proven to be a glutathione precursor.
  • As a glutathione precursor, NAC (along with two other amino acids — glutamine and glycine) is necessary to produce healthy levels of glutathione in the body.
  • Glutathione is a free radical scavenger that’s able to scavenge a diverse assortment of free radicals.

NAC been good for me

Been taking NAC for my respiratory issues. I have a very low immune system. I’m usually congested. Been feeling better when I wake up.

Have A Question? Great, Ask Us!

Really. We are here to answer any question you may have.

How much N-acetyl-cysteine should I take daily?

Since NAC is an amino acid, there is no daily recommended intake (RDI) suggested by the Food and Drug Administration (FDA). We recommend consulting with your physician or healthcare provider to see what dose is right for you.

This product does not have the most pleasant smell. Is it ok?

NAC can have a strong sulfur smell, but it is completely normal and nothing to be concerned about! This is not an indication that the product has spoiled.

What is the suggested use?

Adults, take up to 2 capsules daily without food, or as recommended by a physician or healthcare professional. Do not exceed the recommended dose. Store in a cool, dry place.
