Thanks @njx58 for your response. I have been taking Thorne advanced bone support. I still have another 5 months before my next dexa scan. I took K2 separately for a while, but I think it was giving me joint pain. I just finished the Thorne and thought I would switch to osteo-sustain. On the ingredients for osteo-stim is N-Acetyl cysteine. There seem to be mixed info on that, used to be prescription only. I do take his fortibone collagen and have not had any issues with it. I think I will try “sustain”, not sure about “stim”. I agree about getting what we need from food. I try to take that into account when taking supplements. Thanks.
