Calcium tablets are widely used to treat and prevent calcium deficiency, and their use is strongly supported by scientific evidence. Calcium is an essential mineral necessary for a variety of physiological processes, including bone mineralization, muscle function, nerve transmission, and vascular contraction. When dietary intake is insufficient or when a person has an increased requirement (such as during growth, pregnancy, lactation, or in elderly populations), supplementation with calcium tablets is recommended to maintain normal calcium levels and prevent deficiencies.
Numerous randomized controlled trials and meta-analyses have demonstrated that calcium supplementation can increase bone mineral density and reduce the risk of osteoporosis and related fractures, particularly in postmenopausal women and older adults. Guidelines from major health organizations, such as the National Institutes of Health (NIH) and the World Health Organization (WHO), endorse the use of calcium supplements to prevent and treat calcium deficiency. Additionally, calcium supplementation is a standard treatment for conditions such as hypocalcemia (low blood calcium), certain forms of rickets, and osteomalacia.
The strength of evidence supporting the use of calcium tablets for calcium deficiency is high (rated 5/5), based on decades of clinical research and widespread clinical application. However, it is important to use supplements as directed, since excessive calcium intake can have adverse effects, such as kidney stones or cardiovascular risks in certain populations.
