I take the supplements that are formulated by Keith McCormick from his company called Osteonaturals. I take the Osteo Stim and the Osteo Sustain. I also take the collagen he sells, called Osteo Collagen Pep.
I experimented with different ones for a while but settled on these because they are formulated for bone health.
He has written 2 books about osteoporosis which I have found quite helpful.
