In this short video, I want to cover how NAC works. NAC (N-acetylcysteine) is a highly-studied compound used in emergency rooms for Tylenol overdose. It also helps detoxify if you have alcohol poisoning. Another powerful effect of NAC is the prevention of excessive mucus, fluid, and inflammation in the lungs.

NAC works by increasing glutathione. Glutathione is a major antioxidant. When you have too much poison in your body, glutathione gets depleted. This causes free radical damage and oxidative stress that can destroy the liver. Glutathione protects against poisons and other things that increase oxidation and free radical damage.

Glutathione helps:

• Decrease xenobiotics (poisons in the body)

• Stop free radical damage

• Counter the effects of hydrogen peroxide

• Chelate heavy metals

• Decrease pathogens

• Decrease oxidative stress

Other things that help boost glutathione:

• Alpha-lipoic acid (ALA)

• Vitamin D

• SAMe

A few potential causes of low glutathione:

• Cancer


• Infection

• Trauma

• Burns

• Chronic disease and inflammation

• Overtraining

• Poisoning

• Diabetes
