For more than two years, I have been nearly incapacitated by arthritis in both of my knees. The symptoms have been serious enough for me to consider knee replacement surgery. At 83 years of age, it is my pleasure to report to you that I have been using your capsules containing G.M.1 from mangosteen for a mere two weeks and have experienced a profound improvement in my health and well being. After only a relatively short time of taking your preparation, there is a dramatic improvement in my mobility and a significant reduction in joint discomfort ; so much so that I am no longer considering surgery. In addition, there have been no serious side effects with the use of the capsules. It's my intention to continue using it and will happily keep you informed of my condition
