I am 80 years old and have never taken any drugs for Ostro and I have two doctors opinions one for Prolia and second for Reclast. After researching I don’t like any of those choices. I was told that Collegen doesn’t help. I am considering not taking any drugs. My osteo is borderline and I do lots of exercise and I Square danced for 25 years. I have never had a fracture but I can’t find any doctor that doesn’t want to subscribe drugs. Any comment and good luck.
