My osteoporosis is at -5.7, so I started adding boron to my daily supplements. I couldn't believe it when ALL my symptoms of rheumatoid and osteoarthritis as well as fibromyalgia are GONE. I take between 1-12-15 mg per day in divided doses. There is a wonderful video on You Tube by Dr. Jorge Fleches (who has osteoporosis which he treats with boron). He trained at Loma Linda in California and was able to stop his osteoporosis. I know many people who take large amounts of boron for their osteoporosis and they are having very good reversals. I went from about 15 years of not being able to use my hands for very much at all - I couldn't even make a fist or put sheets on the bed! Now I can crochet and play piano again!
