What Is Calcium Citrate Made From?

Calcium is a natural mineral, needed for strong bones, and it is readily available in dairy products, but some take a dietary supplement to boost their calcium supply. The most common type is calcium carbonate, but calcium citrate is another supplemental form.

  1. Calcium Salt

    • Calcium citrate is the salt that comes from citrus juice concentrates such as orange, lime, lemon or grapefruit, and it can also come directly from the fruit. It is, simply, the calcium salt of citric acid. When it is extracted, it becomes a white powder, without odor, but with a sour taste.

    Easily Absorbed

    • Supplements made from calcium citrate are readily absorbed into the body because they do not require extra stomach acid for absorption. As a result, the calcium goes to work faster because calcium citrate has its own naturally acidic environment. It can also be taken on an empty stomach, at any time. However, those with acid problems should avoid any extra acid, including calcium citrate.

    Pill Numbers

    • Calcium citrate supplemental pills are smaller in size than those made with calcium carbonate, but they do not have as much calcium per pill. Users may have to take more pills to get the RDA's daily recommendation of 1000-1300 mg per day, according to information on Health Castle's website.
