Guest guest Posted August 26, 2003 Report Share Posted August 26, 2003 Most people, not just post-ops, can only absorb 500 mg of elemental >calcium at a time. If you want to get in an admirable 2000 mg a day, you will be taking four doses, ----------------------------------------------- Correct. But please make sure that the 2000mg are elemental. That depends on how the supplement you're taking is labeled. It can be confusing. Carol A Quote Link to comment Share on other sites More sharing options...

Calcium does seem to like the nighttime better. But 2. You can't absorb more than about 500mg at once anyway, so the other 1500mg you're taking at the same time is just being wasted. So's your money. 3. Whoever instructed you that calcium will interfere with absorption of vit D needs to go back to nutrition classes. D HELPS your body absorb calcium. No interference one way or the other with these 2 supplements. 4. Any calcium carbonate, Tums included, is not going to be much help to you. We don't have the stomach acid to break it down quickly enuf to be bioavailable. And, cal carb CAN help create kidney stones (ouch) !! Calcium citrate is best absorbed and no kidney stone risk. 5. Make sure the calcium you're taking (whatever mg dosage it is) is elemental. Calcium carbonate, calcium citrate, ANY kind of calcium is mixed with binders and only a portion of what's in the pill or capsule is pure/elemental calcium. Different mfrs label their supplements differently, and it is often difficult and confusing to find out how much actual (pure/elemental) calcium is in one unit.

Guest guest Posted August 26, 2003 Report Share Posted August 26, 2003 Oh my goodness, Butch, you've been given a truckload of poor information about calcium supplementation. Let's try to untangle it. First, Vitamin D actually HELPS your body absorb calcium, as do magnesium and boron. Next, calcium carbonate is NOT at all good for people who have had RNY. Calcium carbonate requires one hour of exposure to stomach acid to become bioavailable; we do not have that stomach acid nor that exposure time (minimal stomach acid, no pyloric valve). Calcium carbonate can also facilitate the formation of kidney stones, if you are prone to them. Calcium CITRATE is the calcium for us. It was specifically recommended by the 1994 National Institutes of Health Consensus Statement on Calcium as the calcium supplement of choice for people with low stomach acid. Calcium citrate is lab-synthesized, so it has no risk of heavy-metal contamination as the bone meal, coral calcium and other " natural " calcium carbonates do. Most people, not just post-ops, can only absorb 500 mg of elemental calcium at a time. If you want to get in an admirable 2000 mg a day, you will be taking four doses, each separated from the other and from any iron supplementation by at least two hours. Calcium and iron compete for the same receptors in your small intestine, and if you take them together, your body will not take in any of the iron you consume. I have never heard anyone else say that they pee more if they take a dose of calcium citrate before bed, but that's a great time to take it because your body can make better use of calcium when your major bones are not supporting your weight. How much water are you drinking with that calcium, and would you still drink it if you weren't taking the calcium? :-) Personally, I use Mission Pharmacal's Citracal Plus with Magnesium. In two tablets, it contains: 250 IU of Vitamin D3 as cholecalciferol (the right form) 62% RDA 10 mg of Vitamin B6 as pyridoxine hydrochloride 500% RDA (water-soluble, high doses not harmful) 500 mg of elemental calcium as calcium citrate 50% RDA 80 mg of magnesium as magnesium oxide (this is a little low, ideal is 250 mg to 500 mg calcium) 20% 10 mg zinc as zinc oxide 66% RDA 1 mg copper as copper gluconate 50% RDA 1 mg manganese as manganese gluconate 50% RDA 1 mg boron as sodium borate, no RDA established though it's proven to facilitate calcium absorption I hope this information is helpful. Ziobro Open RNY 09/17/01 310/126/141 (goal was 160) Then/lowest/now http://www.ziobro.us/index.html NEW homepage! calcium question I am instructed to take my calcium at night for several reasons, the main one being it can interfere with the absorption of other supplements like Vit D. I generally take two " ultra " strength Tums or the like so around 2000 mg of calcium carbonate, I think. Here is the problem...I think it makes me urinate too much at night. When I don't take it, I can often sleep through the night, but if I do take it, it is up at least once and often twice. First, has anyone else had this problem? Second, are other docs telling you to take it at night or is it just " another " supplement to take during the day with or separate from Vit D? Third, what other calcium supplements are folks using?

Guest guest Posted August 26, 2003 Report Share Posted August 26, 2003 Great explanation, ! I hope those whose docs & /or nutritionists recommend Tums or other " carbs " print this out and show it to them. They may not admit they're wrong, but I guarantee, it'll give them pause, and they'll probably change their tune down the road. in NJ ************************* > > > First, Vitamin D actually HELPS your body absorb calcium, as do > magnesium and boron.

We can only absorb about 500mg at one time. I spread my dosages out over 4 aliquots daily. You can take with or without food, altho some nutritionists insist you'll absorb more/better with food. How much is enuf depends on your age and whether or not you're past menopause. And have you had a Dexascan? If not, you should get one, find out where you stand. If you already have a problem, you'll want to take more calcium, plus some treatment meds. Oh, and, make sure that the mg's you're getting are actually PURE (elemental) calcium, and not the mg's of calcium plus whatever fillers are in the tabs, caps, whatever it is you're taking. And of course, you do know it should be calcium citrate and not calcium carbonate? And that you need 250 mg magnesium and 200 iu dry D3 for every 500mg pure (elemental) calcium? Calcium citrate is between 21% and 29% pure calcium. A lot of people think they're taking 1000mg and they're really only getting 250mg or so. Check it out. If you can't fig it out from the label, call the mfr and talk to a chemist, not a customer service rep. Carol A Quote Link to comment Share on other sites More sharing options...
