Serious question & please don't answer 'my nut' or 'my doc' said so. We have all been told to switch from carbonate to citrate after our surgeries & that we can't assimilate carbonate as well as citrate. BUT the surgery I chose was not to disrupt my G.I. tract, so if carbonate was acceptable before, what makes it different now?

I understand the need for sublingual B-12 as there is less stomach lining, but I just don't have a handle on why the citrate--not to mention I have a lot of the carbonate left from pre-sleeve, LOL!

I am post menopausal, and the pathologist I went to for my bone density test prescribed 1500 mg/day and 400 Vitamin D/day. I do eat a lot of calcium-rich foods but not enough. I detest protein shakes. Most of my protein comes from eggs, cheese,milk, chicken, fish, and turkey jerky.
