calcium absorption

Calcium absorption is the process by which our bodies take in calcium, an essential mineral for bone health, muscle function, and nerve signaling. This occurs mainly in the small intestine, where calcium from food or supplements passes through the intestinal walls into the bloodstream. Factors influencing absorption include vitamin D, which helps the body utilize calcium, as well as certain dietary components like fiber and oxalates that can hinder absorption. Adequate calcium intake is crucial, especially during growth periods and later in life, to prevent bone diseases such as osteoporosis.
