Glutathione or GSH is the most important and powerful intracellular anti-oxidant that the body makes!What is glutathione? Glutathione is a tripeptide molecule made inside cells from the amino acids L-glutamine, L-cysteine and L-glycine. The sulfur atom in L-cysteine is what binds heavy metals and toxins and aids in their removal from the body. Glutathione is also very crucial for proper mitochondrial function and energy production. Glutathione is also needed to protect DNA from damage. Many individuals with chronic illness (chronic infections (i.e. herpes, HIV, Lyme's disease), chronic fatigue, fibromyalgia, heavy metal toxicity, candida overgrowth, etc.) have very low levels of glutathione in their tissues. Heavy metals (i.e. mercury, lead, cadmium) not only cause the body's tissues to use up their supply of glutathione, but they also "directly" inhibit the production of more glutathione by displacing magnesium from the enzyme that makes glutathione! Also, as we get older, our bodies ability to make glutathione declines.
So why not just supplement glutathione to boost the body's levels of glutathione and help restore better health. This has been tried, but once glutathione reaches the stomach it is rapidly degraded and is of no use. Some people have supplemented pre-cursors to glutathione i.e. N-acetyl-cysteine (called NAC for short) to provide the body with the most crucial amino acid needed to make glutathione. But remember some individuals are not able to synthesize glutathione very well due to heavy metal toxicity and/or magnesium deficiencies. Also, NAC is very smelly due to the sulfur atom. If you pass gas while taking NAC, please be prepared to warn others of the horrible smell that is coming their way (i.e. rotten eggs)! Some doctors administer glutathione intravenously. This method works, but obviously it involves a lot of expense given the office visit and the cost of the I.V.
Well thanks to the development of a new form of glutathione called S-Acetyl-Glutathione, there a now a way to supplement glutathione orally without the nasty taste or smell of the pre-cursor NAC or the expense of I.V. glutathione. S-Acetyl-Glutathione is the first orally stable form of glutathione that is absorbed intact and increases intracellular glutathione levels. The acetyl group is attached to the sulfur atom of cysteine in the glutathione molecule. Placing the acetyl group on the sulfur atom of cysteine both protects it from oxidation in the digestive tract and reduces the nasty smell and taste of the sulfur atom. There is NO smelly gas when you take S-Acetyl-Glutathione.
S-Acetyl-Glutathione is a lipid-like molecule that is taken up intact by chylomicrons in the digestive tract. Once S-Acetyl-Glutathione reaches the blood stream, the acetyl group protects it from breakdown by peptidases. Studies show that S-Acetyl-Glutathione crosses the cell membrane more easily than glutathione itself. Once inside the cell, the acetyl group on S-Acetyl-Glutathione is removed and the glutathione molecule is free inside the cell which is exactly where it is needed!!
Did you know that glutathione is not only important for detoxification and energy production, but it is also crucial for proper functioning of the immune system? Too little glutathione in the body results in chronic inflammation because glutathione is needed for the balance between cell-mediated immunity (the TH1 pathway) and humoral immunity (the TH2 pathway or antibodies). T-lymphocytes direct the 2 sides of the immune system. When there too little glutathione present in the body, the humoral side of the immune system dominates and results in the production of cytokines and antibodies that produce a great deal of tissue inflammation. Supplementing S-Acetyl-Glutathione helps restore the balance to the immune system and relieves this chronic inflammatory cycle. If you suffer from chronic pain and inflammation, a chronic infection, or chronic fatigue, then you need to give S-Acetyl-Glutathione a try!
Illnesses that have responded well to S-Acetyl-Glutathione supplementation are Hepatitis, Herpes, Shingles, HIV/AIDS, Lyme's Disease, Cancer, Multiple Sclerosis, Parkinson's Disease, Autism, Allergies, Asthma, Chronic Fatigue Syndrome and Fibromylagia.
