Same health benefits, substantial cost difference!
Where is OGF® manufactured?
OGF® is manufactured at the same GMP certified facility Dr. Keller personally selected 20 years ago.
Why MaxGXL™ label shows a serving size of 3?
The MaxGXL™ label recommends taking three capsules twice a day whereas OGF® recommends taking 6 in the morning, as Dr. Keller intended.
In 2006, Dr. Keller’s Glutathione technology was exclusively licensed to Max International. In 2010, the license became non-exclusive. As a result, RobKellerMD™ started marketing Dr. Keller’s proprietary NAC glutathione supplement as Original Glutathione Formula® (OGF®).
From previous MaxGXL™ customers who have switched to OGF®
Tatiana 
This is a great product for inflammation. I used to take MaxGXL™, and this is the same product but less expensive. Win Win!
Peter
I have been using the OGF® formula since the year it was introduced by Dr. Keller with Max. Tremendous product and does more than is stated.
Kathryn
I started taking the glutathione supplement back in 2003 when it was being sold by Max. Eventually, Robert Keller MD took over and started selling the supplement we have today. I can honestly say that it is responsible for my excellent health.
Fran
I have been an OGF® user since 2007 (began as MAX GXL™ user). I am a user for life! Thank you Dr. Keller and your wonderful family for continuing your legacy of health and wellness.
Pete
Great product cheaper than buying from Max International.
Elaine
My husband and I used MAX GXL™ when it was originally formulated and also became distributors and were active for several years. When OGF® became available more recently we again started using the product and find its continued effectiveness, especially in the fact that my husband is now a nonagenarian (90+) and I am close to being the same!
De Ann
I began using your product as Max GXL™ and was overjoyed when your company got up and running. I have continued to use OGF®, and it is above other similar products in delivery and benefits.
Anne
I appreciate the original formula for what it does and I appreciate the cost compared to Max International that changed the formulation and I think increased the price. I feel the values are similar as far as quality.
