Calcium is a crucial mineral that is essential for many bodily functions, including maintaining strong bones and teeth, nerve function, blood clotting, and muscle contraction. Research on calcium often focuses on its role in preventing osteoporosis, a condition characterized by weak and brittle bones, as well as its potential benefits for cardiovascular health, muscle function, and overall wellness. Studies may also investigate optimal calcium intake levels, sources of calcium in the diet, and the effects of calcium supplementation on various health outcomes.
