Calcium Carbonate vs Calcium Citrate: The Key Differences
Calcium carbonate has more elemental calcium than calcium citrate (40% in carbonate, 21% in citrate). So you may have to take more calcium citrate tablets to get the desired amount of calcium. Thankfully, you don't have to do any calculations. Your supplement's label should tell you exactly how much elemental calcium is in a serving.Web
