Food Chem Toxicol 2017;109:585-648. Calcium plus vitamin D supplementation and the risk of fractures. The percentage of calcium absorbed from supplements, as with that from foods, depends not only on the source of calcium but also on the total amount of elemental calcium consumed at one time; as the amount increases, the percentage absorbed decreases. However, the findings from research on the role of dietary calcium and calcium supplements in reducing CVD have been mixed, and some evidence indicates that calcium supplements might even increase CVD risk.

Those who avoid dairy products because of allergies or for other reasons can obtain calcium from non-dairy sources, such as some vegetables (e.g., kale, broccoli, and Chinese cabbage [bok choi]), canned fish with bones, or fortified foods (e.g., fruit juices, breakfast cereals, and tofu) [1].

Additional well-designed randomized trials are needed to determine whether dietary or supplemental calcium intakes increase, decrease, or have no effect on risk of cancer in general or of specific types of cancer, or on cancer mortality. The recommended upper limit for calcium is 2,500 mg a day for adults 19 to 50.

The U.S. Preventive Services Task Force (USPSTF) concluded with moderate certainty that daily doses of less than 1,000 mg calcium and less than 400 IU (10 mcg) vitamin D do not prevent fractures in postmenopausal women and that the evidence on larger doses of this combination is inadequate to assess the benefits in this population [40]. Food Risk of heart failure among postmenopausal women: a secondary analysis of the randomized trial of vitamin D plus calcium of the women's health initiative. A Cochrane review of 16 trials in 3,048 adults with a median follow-up period of 3.5 months found that calcium supplementation (typically 1,000 to 2,000 mg/day) reduced systolic blood pressure by 1.43 mmHg and diastolic blood pressure by 0.98 mmHg [67]. Postmenopausal women After an average of 7 years, risk of cancer mortality did not differ between groups. In the 13 studiesnone of which administered vitamin D supplementsthat evaluated high doses (at least 1,000 mg/day calcium) in 15,730 women, supplementation reduced the risk of high blood pressure by 35% and, in women with low dietary calcium intakes (less than 1,000 mg/day; 10 trials in 10,678 women), the risk of preeclampsia by 55%.
