What is "calcium"?
Calcium is a mineral that plays a crucial role in various bodily functions, including building and maintaining strong bones and teeth, regulating muscle contractions, and supporting nerve function. It is found in large amounts in the body and is mainly stored in bones and teeth. Calcium is also involved in blood clotting, hormone release, and cell signaling. Having enough calcium is important for overall bone health and can help prevent osteoporosis, a condition where bones become weak and brittle. Good dietary sources of calcium include dairy products like milk, yogurt, and cheese, as well as leafy green vegetables, tofu, and fortified foods.
