Vitamins + Minerals Calcium

Calcium is a mineral that is essential for building and maintaining strong bones and teeth. It is also important for muscle function, nerve signaling, and blood clotting. In food, calcium can be naturally present in dairy products, leafy greens, and fish, or it can be added as a nutrient supplement.

Calcium is added to foods to increase their nutritional value, particularly as a source of this essential mineral. It is commonly found in fortified dairy products like milk and yogurt, as well as in plant-based milk alternatives, orange juice, and cereals. It can also be used as a firming agent in some processed fruits and vegetables.

Calcium is recognized as safe and effective by the FDA when used as a nutrient supplement. The National Academies of Sciences, Engineering, and Medicine have established upper intake levels for calcium. International bodies like JECFA and EFSA have also evaluated calcium. Adequate calcium intake is crucial for bone health, and insufficient intake over time can contribute to osteoporosis. However, very high calcium intake, especially from supplements, may be associated with certain health risks, though research is ongoing.
