  • 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.

Helps immune system Been taking this product for almost two years now. Feel it helps my immune system. May 6, 2014
Good ingredients I have been taking it for a couple of years my health is great and I believe this contributes to it I also take the bio active whey protein along with it May 2, 2014
Look No Further I've tried four or five different Probiotics and this one is as "good as it gets!!!" September 4, 2013
immunity builder I've been using this product for me and my pets for several years. I started with a company that charged a LOT more money, and this has resulted in the same benefits by bolstering our immunities. July 31, 2013
Used properly, it works! When taken 30 minutes after the Bioactive Whey Protein Powder I felt so much more energy. Unfortunately, the powder was on backorder for a time, (It's now available.) That's how I discovered how energized It made me feel. It is somewhat inconvenient to have to time your morning routine. But it's worth the effort. July 21, 2013
Fabulous product! This product contains all the benefits of the well-publicized acetyl-carnitine + lipoic acid research and products, but at TOLERABLE doses! Many of us do not want to take the amount of acetylcarnitine contained in other products! The 1000 mg doses in other products are too strong, and the lipoic they use is too acidy. THIS product is not acidy and has just the right, low dose. Small doses of NAC and vit C are included - just right for me! Try it. You'll love it! (A great deal, too, but don't tell Swanson!) March 17, 2013
IS A PRECURSOR I found no odor in my bottles. To the person who complained about the amount of each ingredient ....this is a precursor which means it will help your body make glutathione on its own. I have read from numerous sources that NAC and ALPHA LIPOIC ACID are both very beneficial for this purpose. Also, if you google DR. PERRICONE'S NEW glutathione serum, he gives a very complete explanation on GLUTATHIONES BENEFITS. January 30, 2013
weird smell My quarrel with this product is the very bad odor coming from the bottle which resembles nothing so much as cat urine. (None of the capsules were broken.) With the best of intentions, I find it impossible to continue with this product. September 29, 2012
not sure I love Swanson. I am not sure if the Glutathione is doing anything for me. I also got the Whey, but I can barely get that down. I dislike milk anyway, so the Whey is ucky for me. I want to think the Glutathione is helpful. but I cannot say for sure. September 25, 2012
Good Value Add up what it would cost to purchase the ingredients in this product separately, and it becomes obvious what a bargain this product is. It contains a comprehensive set of ingredient designed to help detoxify. Without question, I have felt better since utilizing supplements which help the body detoxify. I feel that this product is a good choice both because of the range of ingredients and because of the economical price. September 8, 2012
Quality supplement I have not seen any difference taking this. I take it with whey protein for a 1st thing in the morning boost. I can't say if they really do anything for me, but often times supplements don't show any imediate results. So, I shall continue with this product for overall well being since it's supposed to be good for you. July 28, 2012
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
i am a boxing trainer and saw an article on glutathione accelerators, i did some homework on the subject and found your product. i have been on the tablets now for 1 month and have felt dramatic changes from my skin to my reflexes and all in between. i feel 20 years younger and will be on this product till the day i die, i highly recomend this to anyone in a sporting field November 29, 2011
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
