Can calcium supplements be taken in conjunction with others?

I heard once that calcium will block the absorption of other key nutrients if they are taken after te same meal. Is this true? I usually like to split my supplements (like multi) up and take them throughout the day. A full calcium citrate supplement is taken in three pills, so I’m trying to figure out how to get an adequate amount of calcium every day.

  1. I do, but then the brand I take is organic with a 2:1 ratio of Calcium to Magnesium (which the former needs in order to absorb properly), so there’s no question of any block or interference.

    Good to take calcuim with Vit. D and Vit. C. Both increase absorption.

    Never take with Iron. They block each other.

    No problem whatever. Multivitamins contain calcium so taking some extra calcium is OK.

    If you take mega doses of calcium then you will also need a magnesium supplement to balance the calcium as the two interact and too much of one can cause a deficiency of the other one due to preferential absorption of the one in excess at the expense of the other one.
