Because of its ability to neutralize stomach acid, calcium carbonate is contained in some over-the-counter antacid products, such as Tums and Rolaids. Depending on its strength, each chewable pill or soft chew provides about 270 to 400 mg of calcium [ 14].

The Journal of Clinical Endocrinology & Metabolism. 2004;89(2):632-637. doi:10.1210/jc.2002-021136 Calcium supplements come in different forms that contain different amounts of calcium/ vitamin D. Ask your doctor or pharmacist to help select the best product for you. Because bone densitydrops when bone breakdown outpaces bone formation, scientists reasoned that maintaining an adequate level of calcium in the blood could keep the body from drawing it out of the bones. In the late 1970s, a couple of brief studies indicated that consuming 1,200 mg of calcium a day could preserve a postmenopausal woman's calcium balance. Manufacturers are responsible for ensuring that supplements are safe and claims are truthful. Some companies have their products independently tested by U.S. Pharmacopeial Convention (USP), ConsumerLab.com (CL) or NSF International. Supplements that bear the USP, CL or NSF abbreviation meet voluntary industry standards for quality, purity, potency, and tablet disintegration or dissolution.

The amount of calcium absorbed through the gastrointestinal tract is approximately 30% of the swallowed dose. Vitamin D should be used with caution in patients with impairment of renal function and the effect on calcium and phosphate levels should be monitored. The risk of soft tissue calcification should be taken into account. In patients with severe renal insufficiency, vitamin D in the form of colecalciferol is not metabolised normally and other forms of vitamin D should be used (see section 4.3). green leafy vegetables – such as curly kale, okra but not spinach (spinach does contain high levels of calcium but the body cannot digest it all)

Options for increasing calcium intakes in individuals with lactose intolerance include consuming lactose-free or reduced-lactose dairy products, which contain the same amounts of calcium as regular dairy products [ 1, 3]. Those who avoid dairy products because of allergies or for other reasons can obtain calcium from nondairy 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]. However, these individuals typically need to eat foods fortified with calcium or take supplements to obtain recommended amounts [ 28]. Calcium and Health

Additional research is needed before conclusions can be drawn about the use of calcium supplements to improve bone health and prevent fractures in older adults.

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. Absorption from supplements is highest with doses of 500 mg or less [ 15]. For example, the body absorbs about 36% of a 300 mg calcium dose and 28% of a 1,000 mg dose [ 16].

Intake recommendations for calcium and other nutrients are provided in the Dietary Reference Intakes (DRIs) developed by the Food and Nutrition Board (FNB) at the National Academies of Sciences, Engineering, and Medicine [ 1]. DRI is the general term for a set of reference values used for planning and assessing nutrient intakes of healthy people. These values, which vary by age and sex, include the following: During concomitant treatment with other high dose sources of vitamin D and/or medications or nutrients (such as milk) containing calcium, there is a risk of hypercalcaemia and milk-alkali syndrome with subsequent kidney function impairment. In these patients serum calcium levels should be followed and renal function should be monitored.
