When it comes to boosting your liver health and gaining antioxidant support, nothing quite compares to taking an N-Acetyl Cysteine which is also referred to as N-acetylcysteine or N-acetyl-L-cysteine (NAC) supplement. NAC helps replenish glutathione, a critical component of the body’s defense system. It supports liver health and much more.

## **WHAT IS N-ACETYL CYSTEINE?**

The sulfur-containing amino acid, cysteine, is one of the most important micromolecules your body needs for optimal health. This conditionally essential amino acid is not only necessary for protein synthesis, but also for glutathione production. As the master antioxidant, glutathione plays a crucial role in your body’s antioxidant defenses and contributes to your overall health and wellness.

But as you age, your body’s natural production of glutathione declines. Fortunately, studies show that you can supplement with cysteine, one of the three amino acids that drive glutathione synthesis for additional support. But dietary L-cysteine has poor bioavailability, so it needs to be taken in the form of N-acetyl-L-cysteine, which is easily absorbed by the body.

## **WHY CHOOSE AN N-ACETYL CYSTEINE SUPPLEMENT?**

Liver and detoxification support are two main reasons people consider a N-acetylcysteine supplement. As a form of the amino acid cysteine, NAC helps support glutathione production in the body, which plays a role in detoxification, cellular antioxidant activity and the body’s defenses against damage-causing free radicals. Swanson N-Acetyl Cysteine provides powerful antioxidant amino acid support.
