Hi Emby,
Little Miss A has been taking one tablet of 500mg calcium with 1000IU of vitamin D, three cups of milk, yogurt cup and a cheese (all daily) for the last three years.
Now, I read the responses above, here is what our experience has been so far. Any tablets (sandoz etc.) mentioned here have limited capacity to be absorbed in the body. These tablets are usually made from calcium carbonate (the molecule is bigger) and hard to absorb in the body. For example if somebody is taking 500mg of calcium carbonate tablet daily, does not mean the body absorb 500mg. The absorption rate is anywhere from 50-60%. Yes you heard it correct !!!!
The nature has provided calcium in food (best for absorption), to complment the tablet, one has to take dairy, or other source of calcium and lots of it on a daily basis. Excersie daily for bone mass is also must. Rope skipping has been proven to increase the bone mass. All these for longer period of time and you should get good results.
Hope this helps.....
