Product Overview

Description
  • Foundation for Longer Life
  • Boosts Cellular Glutathione Levels
  • Dietary Supplement

L-cysteine is a conditionally essential amino acid, one of only three sulfur-containing amino acids, the others being taurine (which can be produced from L-cysteine) and L-methionine (from which L-cysteine can be produced in the body by a multi-step process). Cysteine plays a role in the sulfation cycle, acting as a sulfur donor in phase II detoxification and as a methyl donor in the conversion of homocysteine to methionine. Cysteine also helps synthesize glutathione, the body’s most important intracellular antioxidant and a vital detoxifier.

N-acetyl-L-cysteine (NAC) is the acetylated form of L-cysteine that has been used to break up pulmonary and bronchial mucous. It is very efficiently absorbed and has been shown to protect cells directly and support the immune system. NAC is an antioxidant and a free radical-scavenging agent that increases intracellular glutathione at the cellular level. NAC can act as a precursor for glutathione synthesis as well as a stimulator of the cytosolic enzymes involved in glutathione regeneration. NAC has been shown to protect against oxidative stress-induced neuronal death in cultured granule neurons.

Suggested Use

Read the entire label and follow the directions carefully prior to use.

This is one of those lesser-known supplements that everyone should learn about. It is a powerful antioxidant, with a wide range of effects. It seems to work primarily by increasing glutathione levels in the body. Let's focus on what it does for the lungs: NAC is a potent mucolytic (it breaks down and liquifies mucus). For anyone with COPD, emphysema, chronic bronchitis, or who is a smoker or former smoker, NAC is a godsend. It will work quickly to open airways that were previously clogged. One capsule, on an empty stomach (seems to work best when taken with vitamin c) is all it takes to work what seems like a miracle. In an hour or so, breathing becomes much more free and your lungs feel like they are 12 years old again. At less than 20 cents per day, and with no bad side effects (I've been using it for decades without problems) this is one of the most effective nutrients there is. Who wouldn't use it? If ordering from Iherb for the first time, you're in for a treat: Iherb has the best selection, lowest prices and fastest shipping of any online merchant. I believe that nutritional supplements saved my life. I've tried a lot of products, and I know what works and what doesn't. My reviews are honest, straighforward, and based on my experience. Read my other reviews to quickly learn from my three decades of research and experimentation.

Recommended to boost glutathione levels
My nutritionist recommended this product to help boost my glutathione levels. It seems to be working, as I am tolerating eggs, onion, garlic, etc. (sulfur issue) better now.
