Calcium absorption refers to the process by which calcium is taken up and utilized by the body. Calcium is an essential mineral that plays a crucial role in various bodily functions, including bone health, nerve transmission, muscle function, and blood clotting.
The human body can absorb calcium from different sources such as dietary intake of foods rich in calcium like dairy products or supplementation through tablets or capsules. Calcium absorption primarily occurs in the small intestine where it is facilitated by several factors, including the presence of certain enzymes and vitamins (such as Vitamin D), the acidity of the stomach, and the concentration of other minerals like magnesium or iron.
The efficiency of calcium absorption can vary depending on an individual's age, dietary habits, overall health, and other factors that may influence digestion and nutrient uptake. Maintaining optimal levels of calcium in the body is essential for preventing conditions such as osteoporosis or rickets, which can result from either too little or too much calcium absorption.
