How much calcium should I take daily in supplement form?

Jill Weisenberger

Adults should get between 1000 -- 1200 mg calcium daily depending on age. Low calcium intakes over the long term cause low bone mass and could lead to osteoporosis and increased bone fractures. If you choose to supplement, take no more than 500 mg calcium at a time because you cannot absorb calcium well in higher doses. So, for example, if you are going to take 1000 mg calcium daily, take two doses of 500 mg each. If you choose a calcium carbonate supplement, take it with meals. You can take calcium citrate either with or without food. For detailed meal planning and advice on supplements, you should meet with a registered dietitian.
