Answer:

No, it is not necessary to take calcium and magnesium together. In fact, if you need to take large amounts (250 mg or more) of either of these, you may be better off taking them at separate times, as they can compete with each other for absorption.

I would like to know where this rumour came from that you need to take magnesium and calcium together in order to make it work better. I have been under that impression for a long time and have heard it from my health-food store as well. But thanks for the good news anyway.

Hi Frauke - This idea may come from the fact that magnesium plays a role in proper calcium absorption. However, this means that you should make sure you get sufficient amounts of both each day -- not that they should be taken at the same time.
