@pattynau yes, I am still on ai therapy, actually my third one as I had problems with Anastrazole and exemestane. So currently on letrazole. Originally PCP recommended Caltrate D for the osteopenia which is 600mg calcium carbonate. I have since switched to a different one because I have trouble with appetite since the chemo and Ca carbonate requires food for absorption. Currently taking one with calcium citrate/malate (food not required) and take 1000mg twice daily. It only has 20mcg of D3 so I have to take additional because that doesn’t get me high enough even though it’s 400% daily recommendation. Last test put my D3 around 20 and being on ai therapy it’s recommended to be over 30. Since I also take vitamin K2 which helps the calcium go into bones instead of kidneys and vascular system, I add the extra D3 there. So currently I take the calcium supplement (with D3, Magnesium and zinc) twice daily, D3/K2 once daily. On my own (not recommended by the doctors) I also take fish oil once daily and a joint supplement which has boron which can also help the bones. I do strength training 2-3 times a week.
