Product FAQ

What is MaxGXL®?

MaxGXL® is a complex nutritional supplement that uses an ideal combination of nutrients to facilitate glutathione replenishment.
What exactly is glutathione and why is it important?

Glutathione is a tri-peptide of the amino acids cysteine, glycine, and glutamic acid and is the master antioxidant of the body. Without glutathione, we die. The replenishment of the glutathione levels within the lymphocytes (also called white blood cells) increases the efficiency of the immune response. The increase in glutathione levels also results in the proliferation of lymphocytes that act as scavengers, and help to combat infections. It is truly the body's master antioxidant and its importance is critical to health and longevity.

How is MaxGXL® different from other glutathione enhancing supplements? What makes MaxGXL more effective?

Our product, MaxGXL, is possibly the most sensible method of raising glutathione levels inside lymphocytes, or activated cells.

1) MaxGXL has a composition patent for a method of raising glutathione levels in humans.

2) MaxGXL is relatively inexpensive.

3) MaxGXL is taken in capsule form for your convenience.

4) We have had great success with MaxGXL and its ability to raise depleted glutathione levels. Not only will MaxGXL make your cells produce glutathione, it will also recycle existing stores of glutathione and maintain it in its most effective form.

What if I don't have enough glutathione – what happens?

Decreased glutathione may be a result of various types of prolonged stress and hyperactivity of the immune system, which in turn compromises the health of the body's cells.

Why isn't oral glutathione well absorbed?

Glutathione is broken down by acid in the stomach long before it ever reached the cells. Then at this point the molecule would still have to penetrate the cell wall which it cannot do. This is why you must feed your cells the precursors needed for them to naturally produce glutathione inside the cells.

Are there any side effects associated with MaxGXL?

No. There are no known negative side effects associated with MaxGXL

What are the ingredients of MaxGXL^® and what do they do?

Calcium Ascorbate - A mineral salt of Vitamin C. Calcium Ascorbate is 80% Vitamin C and 20% calcium. Ascorbates are less acidic than other types of vitamin C and provide better absorption than ascorbic acid alone. It protects the body from toxins and acts as an immune builder and as an antioxidant. It is essential for growth and repair of tissues. It helps your body to cope with physical and mental stress. Calcium Ascorbate produces the frequency necessary to activate protease so is a key component to proper protein digestion as well. Also maximizes NAC absorption and helps protect existing glutathione stores.

L-Glutamine - The most abundant of all of the amino acids found in the muscles of the body. It has the ability to penetrate the so-called bloodbrain barrier and is readily transformed into Glutamic Acid, which is essential for cerebral function. In other words, this amino acid is used as brain fuel. L-glutamine is an essential dietary component which nourishes cells in the gastro-intestinal lining, liver and immune system. It also preserves liver glutathione after hepatic injury.

Milk Thistle - Contains some of the most potent liver protecting substances known. One of the active phytochemicals called Sylimarin prevents free radical damage in the liver and kidneys. It also stimulates new liver cells and is an excellent immune system builder.

N Acetyl Cysteine (NAC) - N-acetyl cysteine (NAC) is the best dietary source of glutathione. It is a main precursor for the manufacture of glutathione (GSH). N-Acetyl-D-Glucosamine (NAG) is a key precursor in the biosynthesis of mucosal glycoproteins. It protects the underlying tissues from enzymes, acids and bacteria while providing a surface to absorb nutrients.

Alpha Lipoic Acid (ALA) - Alpha lipoic acid increases the body's ability to use cysteine to manufacture glutathione. It also enables the key enzyme required for glutathione synthesis to work at optimal conditions, and induces an increase in intracellular GSH.

Quercitin - Quercitin plays a critical role in regenerating glutathione and helps to eliminate toxic compounds found in the liver.

Cordyceps - Cordyceps functions as an antioxidant and anti-inflammatory agent. It has also been shown to increase liver energy and glutathione synthesis. In MaxGXL, however, its primary function is to reduce inflammation and free radicals by decreasing the thermostat for inflammation called nuclear factor kappa beta.

The MaxGXL^® Story

The Breakthrough

In 1994, Dr. Robert H. Keller founded The BIODORON Institute of Advanced Medicine, a state-of-the-art medical clinic specializing in cutting-edge treatment for immune system disorders and anti-aging.

After reviewing subject lab results for years, Dr. Keller noticed a trend. He kept seeing significantly low levels of uric acid in subjects with immune disorders. He decided to explore this finding, and his initial research concluded that uric acid is the last antioxidant at the body's disposal when all the normal antioxidants have been exhausted.

As Dr. Keller has always been a strong advocate of nutrition, he went back in the literature, seeking the answer to one question: If uric acid is the body's last defense, then what is the first? His investigation led him to a substance called glutathione.

Glutathione (GSH): The Best Antioxidant; The Master Antioxidant
Dr. Keller discovered that the most prevalent, powerful and multifunctional antioxidant in the human body – employed by every organ – is glutathione.

Glutathione (GSH) is a small protein produced naturally in our cells if the requisite precursors are present. It functions both as an antioxidant and glutathione_in_cellan antitoxin and is a major defense system against illness and aging. Our glutathione level actually indicates our state of health and can predict longevity. It has been suggested that in the future, GSH levels will be closely monitored. There are over 70,000 medical articles currently published on GSH, yet most health professionals have only a vague idea of its significance. In the near future, the importance of glutathione will be widely recognized.

The Test

After learning of the importance of GSH, Dr. Keller needed to test the hypothesis that the levels of GSH in subjects with immune disorders were, in fact, severely diminished. To get a current and accurate gauge of a subject's GSH level, Dr. Keller knew the test must measure GSH inside of lymphocytes (white blood cells); however, no such lab test existed.

Using a state-of-the-art medical laboratory, Dr. Keller and his team of scientists developed a proprietary lab test to measure levels of GSH inside the lymphocytes.

The tests confirmed the hypothesis. People who are stressed, aging, lacking sleep, or with any prolonged illness utilize glutathione at an accelerated rate resulting in decreased bodily stores, weakened defenses, and increased risk of illnesses including accelerated aging.

The Challenge

It was clear that the GSH levels needed to be replenished in these subjects. But how? Glutathione is produced naturally from three amino acids: glycine, glutamine, and cysteine. These essential precursors of GSH must be able to make it from the mouth to the gut, then through the cells walls and subsequently the mitochondrial membrane. Therein lies the challenge.

Unfortunately, raising our body's glutathione levels is extremely difficult for two reasons. Eating enough glutathione-rich foods only works in an idealized world where stress, deadlines and fast food are not factors. Orally supplementing glutathione is a good idea, but just not practical. The fragile tripeptide structure of glutathione makes surviving the digestive tract a near impossibility.

The Solution: MaxGXL^®

After years of research and development, Dr. Keller created MaxGXL^®, a product containing the necessary components of glutathione that when absorbed into the body; stimulate the body's own production of glutathione in every cell of the body.
