NAC – Liver Health & Glutathione for Detoxification

5 out of 5 based on 1 customer rating
(1 customer review )

Ready for better focus, happiness, stronger immunity, and a clean and detoxified liver? Because those are all incredible benefits of taking NAC!

NAC (or N-acetyl-L-cysteine) is an important amino acid that helps our body produce glutathione, a liver-detoxifying antioxidant.

Glutathione easily gets depleted when we’re stressed, consuming alcohol or drugs, or eating more sugar-y or processed foods. But super supplement NAC helps us produce more so we can stay sharp!

NAC is a must-have whenever you’re drinking alcohol (it counters the effects of a hangover) or to help with attention disorders (it’s been shown to help children focus). Add a bottle to your cabinet today and unlock a wealth of health perks for the whole family!

N-acetyl-L-cysteine, also called NAC, contains a highly stable form of L-cysteine, an important sulfur-containing amino acid. 

  • Repairs and builds muscle tissue.
  • Nutritionally supports a healthy liver.
  • Supports immune function in the brain and throughout the body.

However, when cysteine is ingested as a supplement, it is oxidized and gets burned up rather quickly by the body. NAC is much more stable. NAC helps neutralize the byproducts of ingested fats and alcohol metabolism.

NAC is a precursor to glutathione, one of the most powerful antioxidants on earth. Glutathione neutralizes free radicals and protects your body from oxidative damage. Glutathione is also your body’s “master detoxifier” and your liver needs it to detox. Without it, your liver simply cannot function. By taking NAC, you can increase your glutathione levels, and help your liver get rid of harmful toxins.

NAC (as cysteine, which it becomes once in the body) is an integral component of connective tissue — tendons, ligaments, and the soft tissues that support our joints. Along with a number of other nutrients (like vitamin C), it is actually part of the material that comprises the connective tissue. NAC is used by elite athletes who have suffered tears and partial tears of connective tissue as part of a post-surgery recovery strategy.
