@blueberre not sure if/how blood calcium levels are factored into choices people make…but, am sure that broccoli with Parmesan cheese is a good way to get more calcium…1 of my docs recommends ricotta cheese, as it is quite high in calcium—I get half skim and mix it with all kinds of things, as it is very bland by itself. Some people also love goat cheese, easier on many than other cheeses.. i do take a supplement, chose one that comes in tiny tabs so I have control of the dosage… vitamin D3 and K2 can help bones…(not everyone can tolerate strontium and boron that are in many combo supplements, though usually in small amounts.) research is key, i use ConsumerLab.com.
