MaxGXL is a 100% natural supplement that has been scientifically proven to increase glutathione levels by an average of 276%. MaxGXL does not contain glutathione (which breaks down during the digestive process, but contains ingredients that stimulate the production of glutathione), including: vitamin C; N Acetyl cysteine, L-glutamine, N Acetyl D-glucosamine, quercetin, milk thistle extract, alpha lipoic acid, cordyceps and conjugated linoleir acid. More information about the benefits of each of these ingredients is described below.
People generally experience these benefits of taking MaxGXL:
- More natural energy – – less likely to tire throughout the day
- Less joint and muscle aches and pains
- Decreased pain in general
- Mood improvement
- Sharper state of mind, mental clarity, and focus
- Younger looking skin – less dry skin, reduced appearance of wrinkles, etc.
- Better sleep – more dreaming and remembering your dreams
- More stamina and endurance – less recovery time after working out
- Better memory
- Reduced inflammation or swelling
- Improved vision
- Improved breathing
MaxGXL is different from an oral glutathione supplement (which is broken down during the digestive process) and is the result of years of experimentation, all culminating in the creation of a blend of the appropriate ingredients in proportionally correct amounts, enabling it to:
1) Utilize the digestive system as a tool, not a hurdle
2) Be preferentially absorbed (because not everything you put into your mouth gets absorbed into your body)
3) Have the ability to pass through two critical membranes – one at the entrance to the cell, and a second at the entrance to that furnace inside each cell called the mitochondria.
4) Have the ability to recycle the spent glutathione through the liver after it has been utilized to eliminate the oxidants that are the byproduct of ATP production within the mitochondria.
Clinical Studies
Dr. Keller’s double-blind placebo controlled, cross-over clinical study on MaxGXL on healthy individuals demonstrated that in only 60 days of use of MaxGXL, every person had an average of:
- 276% increase in intracellular glutathione;
- 46% increase in DHEA and 41% IGF-1 (markers for adrenal function and human growth hormone); and
- 61% decrease in TNF-alpha (marker for cellular inflammation). Read the results of the clinical study here.
Dr. Keller actually developed MaxGXL in response to the needs of his patients, and clinical studies were conducted on some of his patients.
MaxGXL has been demonstrated to raise glutathione levels even in individuals who are immune compromised. The graph below shows the increase in glutathione levels experienced by 4 groups of patients. Group 1 (normal health patients) were tested after 6 months of use, while Groups 2, 3 and 4 (HIV, Hepatitis C, and Chronic Viral Illness respectively) were tested after only 3 months of the MaxGXL regimen. All four groups did have a substantial increase in their blood lymphocyte glutathione levels (211%, 416%, 347% and 270% after 6 months, 3 months, 3 months, and 3 months respectively in normal volunteers, HIV (Human Immunodeficiency Virus) patients, HCV (Hepatitis C virus) patients, and CFIDS/chronic viral illness patients).

Virtually everyone who takes Max products consistently for three months feels a difference (i.e., higher energy levels and other health benefits). 75% of people feel a difference within a week, and 90% within two weeks feel a difference. I felt a difference in my mental clarity within hours of first taking MaxGXL. The clinical study demonstrated that 100% of the people taking MaxGXL increased their intracellular glutathione levels by an average of 276% after 60 days.

MaxGXL is 100% natural. No sugar, starch, yeast, soy, dairy, gluten or preservatives.
MaxGXL contains:
Vitamin C ( as calcium ascorbate) 250mg
Calcium Ascorbate is an optimal nutritional supplement that combines Ascorbic Acid (Vitamin C) with Calcium Carbonate. By combining these two dietary ingredients, it is a buffered source of Vitamin C that will not contribute to gastric irritation in sensitive persons.
N Acetyl Cysteine 375 mg
N-Acetyl cysteine is derived from the sulfur-containing amino acid, cysteine. It is produced naturally in the body and is also obtained from the diet. Along with glutamic acid and glycine NAC is a precursor to glutathione, which is the body’s most important cellular antioxidant. Proponents of NAC find that NAC is an immune enhancer; prevents and treats cancer; detoxifies heavy metals; treats smoker’s cough and bronchitis; prevents heart disease; slows progression of HIV; relieves hangover symptoms; reduces exercise fatigue. It is used as a supplement for bronchitis, HIV infection, cystic fibrosis, cancer chemotherapy support, acetaminophen poisoning, heavy metal poisoning, and septic shock.
I-Glutamine 750 mg
This is the most abundant of the amino acids in the human body. Its main storage site is in the musculature, where about 60% of all the unbound amino acids are glutamine (glutamine makes up a smaller percentage of muscle protein, the main bound form). Glutamine has been called a “conditionally essential” nutrient , because it is non-essential in normal situations (manufactured by the body in adequate quantities; not required in the diet), but in illness or injury becomes insufficient (there is then a need for supplementation from the diet or other sources).
N Acetyl D-Glucosamine 125 mg
Used to strengthen immune function & is one of the building blocks of joint tissue and other connective tissues .In certain studies has been known to restrain and treat cancer. As to all kinds of inflammations, it is able to aid in therapy effectively. And also bone arthritis and joint pains have been reduced with using it alone or together with MSM.
Quercetin 37.5mg
This is an anti-oxidant that belongs to a group of plant pigments called flavonoids that are largely responsible for the colors of many fruits, flowers, and vegetables. Flavonoids, such as quercetin, provide many health-promoting benefits. They act as antihistamines (which are useful in reducing allergy symptoms) and help reduce inflammation associated with various forms of arthritis. Quercetin also works as an antioxidant by scavenging damaging particles in the body known as free radicals. These particles occur naturally in the body but can damage cell membranes, interact with genetic material, and possibly contribute to the aging process as well as the development of a number of conditions including heart disease and cancer. Antioxidants such as quercetin can neutralize free radicals and may reduce or even help prevent some of the damage they cause.
Milk Thistle extract 25mg (Silybum marianum)
Milk Thistle has been used since Greco-Roman times as an herbal remedy for a variety of ailments, particularly liver problems. In the late 19th and early 20th centuries physicians in the United States used milk thistle seeds to relieve congestion of the liver, spleen, and kidneys. Today, several scientific studies suggest that active substances in milk thistle (particularly silymarin) protect the liver from damage caused by viruses, toxins, alcohol, and certain drugs such as acetaminophen (a common over the counter medication used for headaches and pain; acetaminophen, can cause liver damage if taken in large quantities or by people who drink alcohol regularly.)
Alpha lipoic Acid 75mg
Quite Possibly the “Universal” Antioxidant. The body needs ALA to produce energy. It plays a crucial role in the mitochondria, the energy-producing structures in cells. The body actually makes enough ALA for these basic metabolic functions. This compound acts as an antioxidant, however, only when there is an excess of it and it is in the “free” state in the cells. But there is little free ALA circulating in your body, unless you consume supplements or get it injected. Foods contain only tiny amounts of it. What makes ALA special as an antioxidant is its versatility—it helps deactivate an unusually wide array of cell-damaging free radicals in many bodily systems. In particular, ALA helps protect the mitochondria and the genetic material, DNA. As we age, mitochondrial function is impaired, and it’s theorized that this may be an important contributor to some of the adverse effects of aging. ALA also works closely with vitamin C and E and some other antioxidants, “recycling” them and thus making them much more effective.
Cordyceps 300mg
Cordyceps sinensis, known in China as Dong Chong Xia Cao (“Summer Grass, Winter Worm”) and in the West as Cordyceps or The Caterpillar Fungus, has long been used in Traditional Chinese Medicine for the promotion of cardiovascular, sexual and immune system health and as a general energizing tonic, as it oxygenates the blood. Traditional Chinese Medicine have used it to treat fatigue and other ailments for 1,500 years.
Conjugated linoleic acid 100mg
A naturally occurring free fatty acid . Used in small amounts it is a newly discovered good fat that may be a potent cancer fighter. In studies, very small amounts of CLA have blocked all three stages of cancer: 1) initiation, 2) promotion, and 3) metastasis. Most anti-cancer agents block only one of these stages. What’s more, CLA has slowed the growth of an unusually wide variety of tumors, including cancers of the skin, breast, prostate, and colon. Also know to aid in weight loss and the conversion of fat to lean muscle mass and is used extensively by body builders and weight loss professionals. So it is a naturally occurring nutrient with the ability to help you pack on lean muscle, reduce body fat and at the same time possesses health promoting properties.
