I'm in my 70's, osteopenia and osteoporosis diagnosed a few years ago. And I too am short and petite! I choose not to use the drugs and instead have used Algaecal (not with Strontium) as it is calcium that comes from a food source, vitamin D3, Ultra K2-7 + D3, Living Bone and Bone & Marrow - 2 supplements from Ancestral Supplements, use ankle weights for some exercises, walk, play tennis and stand as much as I can instead of sitting. My last Dexa in 12/23 showed no significant increases - I stayed were I was a year ago and I consider that a win. I will continue with what I'm doing until I have another Dexa. At this point with all my supplements there is no way of knowing which is helping and which isn't worth it. So it's costly but at this point, my goal is stay active.
Best to all of you!
