Calcium supplements -
The table shows the calcium and vitamin D content in commonly available supplements table 2. It is best absorbed with a low-iron meal such as breakfast. Calcium carbonate may not be absorbed well in people who also take a specific medication for gastroesophageal reflux called a proton pump inhibitor or H2 blocker , which blocks stomach acid.
See "Patient education: Gastroesophageal reflux disease in adults Beyond the Basics ". Children should not take these supplements. Calcium and vitamin D supplements alone are usually insufficient to prevent age-related bone loss, although they may be beneficial in some people older adults, those with very low intake.
In most people with or at risk for osteoporosis, the addition of medication is necessary to slow the breakdown and removal of bone ie, resorption. Underlying gastrointestinal diseases — People who do not adequately absorb nutrients from the gastrointestinal tract due to malabsorption may require more than to mg of calcium per day.
In such cases, a health care provider can help to determine the optimal dose of calcium. Medications — Your health care provider will review all of your medications to check for possible interactions with calcium. Calcium supplements interfere with the absorption of iron and thyroid hormone, so these medications should be taken at different times.
As an example, loop diuretics eg, furosemide [sample brand name: Lasix] increase the amount of calcium excreted in the urine. On the other hand, thiazide diuretics eg, hydrochlorothiazide can reduce levels of calcium in the urine, potentially reducing the risk of bone loss and kidney stones.
If you start taking a medication that alters how the body handles calcium, your provider may recommend a change in the amount of calcium that you consume daily. See 'Kidney stones' below. Side effects of calcium — Calcium is usually easily tolerated when it is taken in divided doses several times per day.
Some people do experience side effects, including constipation and indigestion. Kidney stones — There is no evidence that consuming large amounts of calcium from foods and drinks increases the risk of kidney stones, or that avoiding dietary calcium decreases the risk.
In fact, avoiding dairy products is likely to increase the risk of kidney stones. However, use of calcium supplements may increase the risk of kidney stones in susceptible individuals by raising the level of calcium in the urine. This is particularly true if the supplement is taken between meals or at bedtime, and this is one of the reasons it is better to get most of your daily calcium requirement through your diet.
See "Patient education: Kidney stones in adults Beyond the Basics ". Vitamin D decreases bone loss and lowers the risk of fracture, especially in older adults. Along with calcium, vitamin D also helps to prevent and treat osteoporosis.
Adequate vitamin D is needed for efficient calcium absorption. Vitamin D is normally made in the skin after exposure to sunlight. See "Patient education: Vitamin D deficiency Beyond the Basics ".
Recommendations for vitamin D — Getting adequate vitamin D is important for bone health in everyone. Experts recommend that males over 70 years of age and postmenopausal females consume at least international units 20 micrograms of vitamin D per day.
Lower amounts of vitamin D intake may not be adequate, while very high doses can be toxic, especially if taken for long periods of time.
Although the optimal intake has not been clearly established in premenopausal females or in younger males with osteoporosis, international units 15 micrograms of vitamin D daily is generally suggested. Vitamin D is available as an individual supplement and is included in most multivitamins and some calcium supplements table 2.
Milk is a relatively good dietary source of vitamin D, with approximately international units 2. Most healthy people don't need to check with their health care provider before taking standard doses of a vitamin D supplement.
If you are not being treated for vitamin D deficiency, you probably don't need monitoring of your vitamin D level. However, recommendations for vitamin D supplementation may be different in people with certain underlying medical conditions, such as sarcoidosis or lymphoma.
In these situations, a provider will determine if supplements are needed; if so, the person's vitamin D and calcium levels should be monitored with regular tests. Your health care provider is the best source of information for questions and concerns related to your medical problem.
