N-acetyl cysteine (NAC) is the most common form of the amino acid cysteine. Its most important job is as a building block in producing the network antioxidant glutathione.
Glutathione, sometimes called the "Master Antioxidant," is the most abundant antioxidant in your body, and one of the most important ones. Your levels of glutathione largely determine whether you feel good and have plenty of energy, or you don't. When your levels of glutathione drop, you also leave yourself open to increased risk from all types of degenerative diseases.
Your body normally makes its own supply of glutathione, but this ability begins to decline when your are in your 20's and continues to decline as you age. At age 80, you'll have less than half of your optimum supply.
Supplementing with both NAC and Alpha-Lipoic Acid is the surest way to maintain optimum levels of glutathione. And when you raise your glutathione levels, your body is fortified against any illness that has to do with free-radical overload, including all degenerative diseases.
Your body can also produce its own lipoic acid, but that ability declines with aging, too. Only surplus lipoic acid is used for the production of glutathione — and normally, lipoic acid keeps quite busy doing other jobs. If you're not producing enough lipoic acid, there won't be any available to act as a building block for glutathione production.
N-acetyl cysteine is frequently used for drug and alcohol overdoses, due to its detoxification properties. It is used for treatment of overdoses of acetominophen (tylenol) and has also been studied as a treatment for AIDS because of its ability to increase T-cell numbers.
Supplementing with N-acetyl cysteine, besides boosting your levels of glutathione, has its own list of benefits:
N-acetyl cysteine also improves the body's ability to eliminate environmental toxins such as:
