Unlike deficiencies of vitamin B12, iron, and folate, for which periodic blood testing is a sensitive indicator of status, calcium deficiency is more difficult to detect. Only 1% of the body’s calcium is in the blood stream, the rest being in bones, teeth and marrow. When blood stream calcium is low, the body regularly borrows calcium from bones and marrow. Consequently, blood stream calcium is seldom low even when the body intake is insufficient. The blood stream calcium may be adequate, but the bone calcium level has been depleted. Hence, a blood test for calcium will not register a bone calcium deficiency. A bone density scan is required to do this. Once ingested, calcium normally is absorbed in the duodenum and proximal jejunum by an active saturable process that is assisted by vitamin D. The surgical exclusion of these intestinal segments from digestive system acts to diminish net calcium absorption.
A second factor affecting calcium absorption is the form of the calcium. Calcium is most commonly available as calcium carbonate and calcium citrate. Calcium carbonate, table chalk, has a higher concentration of calcium and is less expensive. However, calcium carbonate is not absorbed well in a non-acidic environment. Calcium citrate has a much higher bioavailability rate than calcium carbonate(7), particularly for gastric bypass patients who have little if any stomach acid available to assist in absorption. Sorry this is so long, but it explains a lot. I believe most NUTs that know what they are talking about will suggest calcuim citrate, which is not what is in most of those chews. Hope this answers your question, and of course there are docs and nuts that people have that will just say any suppliment is fine.

HI LAURA...FIRST I WANT TO WISH YOU THE BEST FOR YOUR WLS TOMORROW!!!
AFTER MY SURGERY I WAS TOLD TO TAKE FLINTSTONES WITH IRON AND THEY WERE CHEWABLES FRUIT FLAVORS. I AM NOW USING PRENATAL VITAMINS WHICH ARE PRESCRIPTION. I AM ALSO TAKING CITRACAL CALCIUM CITRATE PETITES WITH VITAMIN D. THE ONLY OTHER MEDICINE I AM NOW TAKING IS MY ANTI DEPRESSANT.
