When asked why and how Dr. Keller developed MaxGXL, he had this to say:
"Well, I guess I will start with the negative. I didn't develop it because I learned about glutathione
and its importance in medical school, medical post graduate training, or even in my years in
academic medicine. But I did open a practice and my patients really caused me to learn
nutrition, and I found a very common anomaly in the laboratory values of my patients (which I
look at all the time). I couldn't really understand it, and finally I decided to explore it, and found
out that it was a thing called uric acid and when low, it meant that the body was using uric acid
as the only available antioxidant, because everything else had been used.
"I said; If that's the last one standing, what's the first? And after a lot of fooling around in pub
med (which is the national medical database), I found this substance called glutathione. At
that time (in 1996) there were 66,000 articles on glutathione in the literature. Unfortunately, they
were in basic science literature that doctors don't read. They can't, they don't have the time.
Now there are over 77,000 articles on glutathione, and yet, if you look in the standard textbooks
of clinical medicine, glutathione is still not even mentioned.
"I went about developing a formulation that took three years and when I finally developed something
I thought worked, I went back and said; It's not enough to know the patients are feeling
better, I need objective evidence that it's working. So, I went back to look at a glutathione test,
and lo and behold (to my surprise!) I found out that the only glutathione test that was used
clinically, was one that measured glutathione in red blood cells. The only problem with that is
that red blood cells live from 90 to 120 days, and as a result you don't get a very good view of
what's happened over the last three months or four months in the body and it really doesn't
give you real fine data.
"So as a result of that and because of my training, I went back into the lab and actually
developed a glutathione test that could measure real-time glutathione in lymphocytes. The
importance here is that lymphocytes only live or exist in the bloodstream for about six hours, so
you are really getting a good snapshot of what's going on in the body at that moment,and not
over three or four months. Fast forward about six years because we had a little nutrition
company called VitaMune and all-told there were probably 300 people (including everybody in
my family) were on the glutathione supplement, and I had the wonderful occasion to meet Steve
Scott through a very interesting series of coincidences. In any case, Steve challenged me to
actually make what I had better. So we went back into the lab, reformulated, recreated, and
came out with what is now MaxGXL.
"Before we ever decided to do anything with this, all the owners went on the product, and we
actually changed the product and had several different formulations. We found one that worked
for everybody, and therefore MaxGXL was born! So that was 15 years of my life in less than
five minutes."
