@lamd yes, I take the 3 pills a day in addition to the collagen. I do not know yet what the results will be until my next scan. I am also taking Tymlos so it will be hard to tease out. In the book, Great Bones McCormick writes extensively about various supplements that have evidence of being helpful.
I haven’t looked specifically at the Thorne advances bone support or the pure encapsulation calcium, but those are both good brands and third party verified.
It is frustrating that we have to research all this on our own. The mantra is always “ask your doctor” but all my doctor knows about is calcium and vitamin D, and I don’t think that can be the whole story.
Best of luck to you on your journey!

Edited to add-
When you are looking at the osteonaturals label remember that the amount of the nutrients listed is for all 3 pills. 3 pills is considered to be one dose. That’s o e of the things I liked about it - no mega doses of anything.
