This conversation has confused me. I am being seen by an endocrinologist at The Mayo Clinic in Rochester. My Dexa for my spine was osteopenia but my trabecular score was osteoporotic and wasn’t good. My CTX blood marker showed high reabsorption. He suggested I shouldn’t wait to start treatment and prescribed Reclast, calcium carbonate and vitamins D. I have had one infusion. From this conversation, if I have understood it correctly, Reclast isn’t preferred because it inhibits new bone building. Is this correct? Also I read the study about the mice (https://pubmed.ncbi.nlm.nih.gov/25314004/ ) and it suggests taking a calcium-collagen chelate dietary supplement. Have any of you found this product and are taking it?
