Do your own research and see what makes sense is my suggestion. I am on the bone meds myself. After researching, I don't believe anything they are trying to sell you makes sense unless you are unable to google search yourself. Use Google Scholar and the NHI (National Health Institute) and ask your doctor for sources. The problem is that supplements don't go directly to building bones. I don't feel that anything I've read helps. If you need to pay someone so you will exercise, then maybe... Grifters and snake oil salesmen take advantage of people.
