Harvard found calcium to be more bioavailable in plants. https://www.hsph.harvard.edu/nutritionsource/calcium/#:~:text=*Bioavailability%20of%20calcium&text=For%20example%2C%20dairy%20foods%20have,a%20higher%20bioavailability%20than%20dairy https://www.hsph.harvard.edu/nutritionsource/calcium/#:~:tex.... What's your source for animal-based calcium being more bioavailable? I had my calcium tested as a vegetarian and later as a vegan and it's gone up.

The studies I read suggest oxalate and phylate inhibit absorption. For instance https://pubmed.ncbi.nlm.nih.gov/12088515/ https://pubmed.ncbi.nlm.nih.gov/12088515/ As a layperson, perhaps I misconstrued bioavailabilty and absorption because both come into effect. I glad your calcium levels have risen btw, I would wonder if other effects like exercise or overall dietary sufficiency have changed. If for instance you ate less foods with chelating agents you'd alter iron absorption, perhaps your dietary shift removed confounding phylate? And no matter why, it's great they rose.
