calcium citrate vs calcium carbonate
calcium citrate vs calcium carbonate
Most adults fall short of the 1,000-1,200 mg daily calcium target, and choosing between calcium carbonate, citrate, and other forms is confusing because they differ in elemental calcium content, absorption, cost, and tolerance. This comparison breaks down every common form, shows which is best absorbed (citrate) versus best value (carbonate), and explains how meal timing, stomach acid, and 500 mg dose limits change results. A side-by-side comparison table, a situation-based decision guide, and direct answers to medication-interaction questions, including calcium with diltiazem and Macrobid, help you choose the right supplement safely.
