Hi. I have just heard about the potential for boron supplements to treat symptoms of osteoarthritis. I just turned 69, and have extensive joint pain in many parts of my body, especially my hands, shoulders, knees, and lower back and right side. (I recently had X-rays of my spine and was found to have extensive arthritis.) I take glucosamine/chondroitin complex already, and wonder if a supplement of some form of boron would help ease the pain, or even help rebuild cartilage? If so, how would I determine dosage?
