I used to use Gluco to relieve my knees from lots of jump smashes. It does help a bit. Not cheap. But after I drink kangen water it the pain went away. My guess is that it could be due to the acid building up over a period of time.

Those who want to try it free can let me know. It's just a miracle water thats all. Call 012 7003361 to pick up. Bring a couple of 100plus empty bottles.
