carbonate x citrate
FYI - i found a liquid calcium which I just love. I get tired of taking pills so I found this and my dietician okayed it also. It is Wellesse Calcium & Vitamin D3. 2 tblsps= 1000 mg of calcium citrate & 1000 mg of vitamin D3. The best part is it tastes like orange dreamsicles...yummy! I get it at Walmart.
