Nutrition & Diet What multivitamin do you take?

There are many studies showing that calcium inhibits the absorption of iron. (This goes for both heme iron (iron from meat) and non-heme iron.) This is probably why iron and calcium are rarely in the same multivitamins.

Here is the conclusion in an editorial article in American Journal of Clinical Nutrition:
The balance of evidence thus clearly indicates that calcium in amounts present in many meals inhibits the absorption of both heme and nonheme iron. A practical conclusion is that those with high iron requirements (eg, adolescents and menstruating and pregnant women) should try to restrict calcium intake with main meals, which contain most of the dietary iron, and that calcium supplements, when needed, should preferably be taken when going to bed.

Thank you,IS!I am considering something without iron for now.I think the calcium supplements have too many side effects so I am not willing to take them.I was at first thinking about a regular multi and than just taking a calcium supplement but I don't like the risk factors.I realize with some of the research I have seen nothing seems to be conclusive but it's too high for me.
