  • Dr. Stephen Langer's Glutathione Precursor Complex



  • A glutathione boosting complex that features pharma-grade aminos, TMG, ALA and other antioxidants and energy supporting nutrients



  • Includes an advanced form of glutathione called Setria for increased bioavailability


Dr. Stephen Langer's Glutathione Precursor Complex combines the three amino acids that make up glutathione (a tri-peptide combo of glutamate, cysteine and glycine) along with supporting nutrients for optimum absorption and utilization. For those over 45, and certainly those over 60, a glutathione boosting program may be beneficial, as it is critical to overall health and no one is immune to the natural production declines that come with age. To help support positive energy and optimal physical fitness, Glutathione Precursor Complex features the following key ingredients: Setria Glutathione, glutathione in its reduced form for optimum bioavailability; Pure Amino Acids, AjiPure pharmaceutical-grade L-glutamine and L-cysteine; TMG for glutathione synthesis; Vitamin C to boost glutathione in red blood cells; Alpha Lipoic Acid to help regenerate glutathione's antioxidant potential; Standardized Milk Thistle, one of the most potent liver nourishers available; and Acetyl L-Carnitine, which aids in the uptake of glutathione and may enhance its activity.

More About Glutathione:

Glutathione is the body's most important intracellular antioxidant. It works inside the cells, quenching the free radicals that are formed through normal cellular processes. Without glutathione, we would be quickly overcome by free radicals. And in addition to its antioxidant properties, glutathione is a master detoxifier. It's particularly important within the organs that are responsible for cleansing our bodies, especially the liver and kidneys, but also the lungs and intestines. Glutathione is also important to the immune system. It's essential to the production and replication of white blood cells known as lymphocytes, and it's particularly vital to the activity of specific lymphocytes called "natural killer" or NK cells.

Didn't digest very well Wanted to take, but it seems to irritate my esophagus. April 3, 2012
With the Whey, It's Very Effective Not just energy, but a sense of well-being has permeated me since using these two products. Dr. Stephen Langer's whey proteing powder is the sister product. Combined, they really help me feel great. March 24, 2012
As We Age Dr. Stephen Langer's Glutathione Precursor Complex from Swanson Vitamins is an awsome product. As we get older our bodies produce less glutathione which is crucial to good health. I would recommend anyone 40 years of age and older to try this product. It bolsters and fosters good health and immune system. It is also a great way to acquire a cleaer mind and body. With all the pollutants in this world today we need a healthier view on life. I would recommend this for anyone and everyone. March 13, 2012
My Favorite Supplement I take this supplement when I eat a protein bar, and I find my energy level and endurance improve significantly. It's a game-changer. If you want the biggest bang for your buck, try this product when you eat high quality protein. It has significantly improved the quality of life for me. February 27, 2012

gave me a feeling of well being I have been taking this product about a week and i am already feeling like i want to get off the couch and do something. which i have not felt like doing something for quite a while.. i hope this feeling continue. July 14, 2011
Dosages are horrible Swanson been doing this alot. The dosages are horrible here. This product will do nothing for no one. The milk thistle at 50mg will not even be absorbs. Glutathione absorption rate is horrible to put I need to research there formula of it but at 37mg a new born baby will not even benefit. Don't take my word. Research the absorbtion of each and research dosages that may do some good. This forula is wayyyy off. July 4, 2011
