Calcium\ncarbonate is inexpensive, but is absorbed best when taken with food. Some\nover-the-counter antacid products, such as Tums\u00ae and Rolaids\u00ae, contain calcium\ncarbonate. Each pill or chew provides 200-400 mg of calcium. Calcium citrate, a\nmore expensive form of the supplement, is absorbed well on an empty or a full\nstomach. In addition, people with low levels of stomach acid (a condition more\ncommon in people older than 50) absorb calcium citrate more easily than calcium\ncarbonate. <br>\n<br>\nThese two forms of calcium (calcium citrate and calcium carbonate) are well\nabsorbed as is calcium phosphate. <br>\n<br>\nCalcium absorption is best when a person consumes no more than 500 mg at one\ntime. So a person who takes 1,000 mg\/day of calcium from supplements, for\nexample, should split the dose rather than take it all at once. <br>\n<br>\nCalcium carbonate is the fortificant used in most soymilk sold in the U.S. As\nnoted above, it is well absorbed. A variety of calcium salts are used to\nfortify orange juice. There has been little research on their relative\nbioavailability. One study found that calcium citrate malate was quite\nbioavailable.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A VRG member has osteoporosis and asked about the bioavailability of different vegan calcium sources such as fortified soymilk, vegan supplements, etc. VRG Nutrition Advisor Reed Mangels, PhD, RD responds: There&#8217;s not a lot of difference in terms of the percentage of calcium absorbed from different forms of calcium.
