I am 61 years old and I started taking Boron about 2 months ago. With in the first month I noticed a big difference in my arthritis. I could actually bend my knees enough to tie my shoes again and I could crack my nuckels again but the best think I have found is I have no more leg cramps. I weighed 285 but now I've lost 20lb. I take the Boron supplement in pill form they are 3 mg and I take 3 of them ever morning. Some day I may try the Borax powder but right now the supplement is doing fine.
