CALCIUM CARBONATE VS CALCIUM CITRATE

Not all calcium supplements are created equal. Calcium carbonate, the form of calcium found in Caltrate, is the most concentrated form of calcium.

Calcium supplements are generally made with one of two sources of elemental calcium: either calcium carbonate or calcium citrate. Calcium carbonate, the form of calcium found in Caltrate, is the most concentrated form and is commonly found in food and drug stores.

Most formulas supply calcium in the form of calcium carbonate. Calcium carbonate, which is found in Caltrate +++, is more concentrated, allowing for smaller or fewer tablets.

And fewer tablets mean your bottle of Caltrate may last longer per bottle compared with other forms.

Let’s compare the two forms:

Calcium carbonate – Caltrate

  • Concentrated form of calcium
  • Yields about twice the amount of elemental calcium as equal amounts of calcium citrate
  • Provides same amount of calcium in a smaller-sized tablet than products using calcium citrate

Calcium citrate

  • Bulkier form of calcium
  • Yields about half the elemental calcium than equal amounts of calcium carbonate
  • Requires more tablets or larger tablets than calcium carbonate products to get the same amount of elemental calcium
