Hi dappy, I agree with you. I've just added 3mg of Boron to my New Chapter Bone Strength. It has the Ds and the Ks and the Mag and the Strontium. This may be a repeat like I'm famous for bc of my memory problems, but I just learned from my nutritionist that vitamin D needs fat to do it's work enabling the body to absorb calcium. My Bone Strength is plant-based (algae) calcium which is supposed to be more easily digested by the body. I din't know, there is a bone-based supplement that my friend takes as well. It has good logic to ingest animal bone which is supposed to be identical to our own. Here's a link to some of those options;

Good luck making your decision! Many blessings, Sunnyflower @contentandwell @criss

dappy, I agree with you. I wonder how many people who have taken the bisphosphonates end up having fractures anyhow. I have a sister who claims her osteoporosis was reversed after she started jumping on a small trampoline 10 minutes a day. She has been taking some kind of multi mineral supplement . My neighbor took the bisphosphates for 5 years, stopped, and later was found to have a fractured vertebra without knowing what caused it. I have osteoporosis of the spine but would rather avoid taking the medication unless the effectiveness is high enough to seem worth it.
