What food group is the richest source of calcium?

Dairy products are considered the richest source of calcium among the food groups. This is because dairy foods, such as milk, cheese, and yogurt, contain significant amounts of bioavailable calcium, which is easily absorbed by the body. Calcium is essential for several bodily functions, including bone health, muscle function, and nerve transmission.

While other food groups can contribute to calcium intake—such as certain leafy green vegetables, fortified plant-based milks, and some types of fish—dairy provides a higher concentration of calcium. The body’s ability to utilize calcium from dairy sources is also enhanced compared to many plant-based options, making dairy the preferred source for achieving adequate calcium levels in the diet. This is particularly important for populations in need of calcium, such as children, pregnant women, and individuals at risk of osteoporosis.
