Cardiovascular disease Some research has raised concerns about calcium supplements and heart health. Bone health Calcium is one of the most important nutrients required for bone health.

Possible reasons: The study only looked at calcium intakes from a supplement provided to the participants, and did not account for calcium from the diet or estimate the total amount of calcium from both food and supplements.

The trial did not find a difference in incidence of colorectal cancer between the two groups. Kidney stones At one time, experts recommended that people with kidney stones limit their calcium intake because the mineral makes up one of the most common types of stones, called calcium-oxalate stones.

Taking more than 2, mg daily is not recommended for adults even with osteoporosis, as this can potentially lead to other health problems.

It is not recommended to take more than 1, mg daily, even with a diagnosis of osteoporosis. Taking too high an amount of calcium at one time, particularly from a supplement, can actually lower the absorption of the mineral.

It is best to take no more than mg at one time. If you are prescribed more than that, take each dose at least 4 hours apart. So if you are prescribed mg of calcium daily, you might take a mg supplement with breakfast and then again at night with dinner. The two most common types of calcium supplements are in the form of calcium carbonate and calcium citrate.

The carbonate form needs to be broken down by stomach acid before it can be absorbed, so it is usually taken with food; the citrate form does not require stomach acid and can be taken without food. If you are unsure about how much calcium you are getting from the diet, consult with a registered dietitian.

You would subtract the estimated amount of calcium from food from the RDA or prescribed amount by your doctor; the remaining can be taken as a supplement. If you are eating a very high calcium diet f e.

daily , inform your doctor so they can estimate that amount into your calcium prescription. References Institute of Medicine US Committee to Review Dietary Reference Intakes for Vitamin D and Calcium; Ross AC, Taylor CL, Yaktine AL, et al.
