The Development of Dr. Keller's Patented MaxGXL Formula

Despite Dr. Keller's academic and medial achievements, his greatest ambition is to improve the quality of life for as many people as he can.  This includes the patients he sees in his practice, many of whom are battling life-threatening diseases.  Dr. Keller credits his patients and their health challenges with leading him to develop the formula behind MaxGXL.  "It quickly became obvious, when I left academia and began my practice, that writing prescriptions wasn't the best way of helping my patients," Dr. Keller says.  "I had to learn about nutrition. I discovered that virtually all of the people I treated were deficient in antioxidants, so I began to research antioxidants in depth."  Dr. Keller realized that of the four antioxidants the body considers essential enough to make itself, Glutathione was the most prevalent and the most important.  He set himself the task of creating a nutritional product that could increase glutathione levels in the body.  After several years in the laboratory and as many as 20

supplement prototypes, Dr. Keller finally reached a formula that satisfied him. "I am always the first guinea pig for anything I produce," he says. "Once I know it's safe, I try it on my patients." He did, and the results were impressive.  Yet, ever the scientist, Dr. Keller wanted irrefutable clinical evidence that his product worked.
MaxGXL Formula Patented, Proved and Approved
"I spent a year creating a proprietary lab test to measure glutathione levels within lymphocytes," he says.  Unlike red blood cells, which were used to determine glutathione levels when he began his quest and which live for 90 to 120 days, lymphocytes are white blood cells that have an average lifespan of les than six hours in the bloodstream.  Using lymphocytes made it possible to measure what is happening in a patient's body in real time.  Thanks to the results of this test - and the uniqueness of the MaxGXL formula - the product has not only received a World Wide Patent as well as a Composition Patent, but has also been listed as an Approved Quality product by Consumer Lab.  This leading provider of independent test results has even run MaxGXL through its Athletic Banned Substance Screening Program and given it the green light.  Dr. Keller is delighted that Max International has enabled more people to have access to the benefits of his product.  "For nine years, we were lucky if we reached an audience of 250
people," he says. "Now the message is getting out and the product is doing wonderful things for so many more.  That's incredibly rewarding."  Dr. Keller himself reaps the rewards of MaxGXL daily, in terms of his own energy levels and stamina.  He swims and works out regularly, sees patients three days a week, is writing a book, conducting trials on two drugs he has developed, and much more.  "Thanks to the supplements I take, including MaxGXL, I can do as much as I could 20 or 30 years ago!".

MaxGXL Patent Information filed with US Patent and Trade Organization

"This product, in my opinion, represents the single most important breakthrough in health that I will witness in my lifetime. I believe it will revolutionize, change, and transform the practice of medicine world-wide and make Dr. Robert Keller more famous than Jonas Salk who created the polio vaccine.”

Dr. John C. Nelson , 159th President of the American Medical Association

Dr. Keller's HIV/AIDS Project In Tanzania Africa


Dr. Keller has created a non toxic, inexpensive HIV/AIDS treatment that was designed specifically to address the huge HIV/AIDS crisis that exists in Africa and other 3rd world locations.  These places in our world are unique in that there exists in those locations another serious threat to the immune system that pre-dates the arrival of HIV/AIDS; this disease is Malaria.  More than half of those who suffer from HIV/AIDS in Africa are also co-infected with Malaria.  Either disease can kill you, so you must treat both if you are to save a life.  When Dr. Keller created his HIV/AIDS drug he understood this dilemma, and purposely built into his drug a highly effective treatment for Malaria as well, so we are able to treat both of these killer diseases simultaneously.

A percentage of every box of MaxGXL sold directly supports this tremendously important project.
