That sounds reasonable to me. Your T-Scores are not terrible (not good but they could be so much worse). I reached a -4.0 in one vertebrae before I gave up on avoiding meds. That was probably too far to go but luckily I have not fractured and now my vertebrae are all better than -2.5. So hopefully I'm much much safer than before.
Oh, I see your CTX is rather high. That bears watching. For myself I consider above 250 for CTX as heading in the wrong direction. I think the CTX has to be considered along with other bone markers and DXAs and one's overall health so that there is not like an absolute scale that shows what is good or bad. That's one reason more docs don't use the markers. But from what I've read I think 300-400 is the start of an imbalance of too much bone cleanup. Above 400 like 600 plus it gets more and more likely you are losing too much bone. But I'm definitely no whiz on bone markers so do your own research on that.

BTW the changes you are making sound great. I would suggest adding Vitamin K2 MK4 if you are increasing Vitamin D. And yes MK4 not MK7 which more people recommend. Also Bioidentical Hormones are a good thing to consider if that hasn't already been mentioned in this discussion.
Best of luck to you (and to all of us dealing with this problem)
