calcium carbonate vs calcium citrate

[No game 14,437]

Why so cheap? Is it because of the auto shipping?

Nothing?? Nada?? Well then...

Calciium in supplements are in the form of Calcium carbonate or calcium citrate. Calcium carbonate is inexpensive and more commonly available. Both forms are well absorbed HOWEVER patients with decreased stomach acid (i.e. after gastric sleeve surgery) will absorb calcium citrate more easily. These supplements contain different amounts of ELEMENTAL CALCIUM, which is the actual amount of calcium in the supplement. Calcium carbonate in supplements is only 40% ELEMENTAL CALCIUM. For example if a supplement contains 500 mg of calcium carbonate, only 200 mg is elemental. The other 300 mg is the carbonate ingredient. Calcium citrate is 21% ELEMENTAL CALCIUM but it is better absorbed than calcium carbonate and does not require acid for absorption.

Yep, what she said....and said very well.
