N-Acetyl-l-Cysteine (NAC) is a derivative of the dietary amino acid l-cysteine and is a sulfur-bearing amino acid. With a high affinity for lung tissue, which it supports through mucolytic and antioxidant action, it may improve the functioning of your respiratory system. NAC also supports tissue levels of glutathione, a key component of the body's free-radical scavenging defense system.
Since N-Acetyl-l-Cysteine contains sulfur, cellular metabolism of the di-sulfide bonds may help clear the lungs where bacteria and other particles are trapped in mucus.
Because of its ability to dissolve mucus, NAC may also help relieve allergy symtoms and help increase your overall natural defense system.
NAC is very important for glutathione synthesis which provides some of the most powerful antioxidant action in the body, keeping cells healthy and protected against roaming free radicals and oxidative stress. This is especially helpful for seniors.
Supplementing with N-Acetyl-l-Cysteine may boost the level of glutathione present in the tissues which can increase immunity, support the proper functioning of lymphocytes which are immune system components, and improve cellular detoxification, as in heavy metal cleansing.
