Calcium supplements are salts of calcium used in a number of conditions.[1] Supplementation is generally only required when there is not enough calcium in the diet.[2][3] By mouth they are used to treat and prevent low blood calcium, osteoporosis, and rickets.[1] By injection into a vein they are used for low blood calcium that is resulting in muscle spasms and for high blood potassium or magnesium toxicity.[2][4]
Common side effects include constipation and nausea.[1] When taken by mouth high blood calcium is uncommon.[1] Calcium supplements, unlike calcium from dietary sources, appear to increase the risk of kidney stones.[1] Adults generally require about a gram of calcium a day.[1] Calcium is particularly important for bones, muscles, and nerves.[1]
The medical use of calcium supplements began in the 19th century.[5] It is on the World Health Organization's List of Essential Medicines.[6] It is available as a generic medication.[3] In 2021, it was the 235th most commonly prescribed medication in the United States, with more than 1million prescriptions.[7][8] Versions are also sold together with vitamin D.[3] In 2020, the combination, calcium/vitamin D was the 215th most commonly prescribed medication in the United States, with more than 2million prescriptions.[9][10]
