Which source of calcium is considered the most bioavailable for athletes?

Dairy products are recognized as the most bioavailable source of calcium for athletes due to their high calcium content combined with the presence of lactose, which enhances calcium absorption. In addition, dairy items often contain calcium in a form that the body can utilize more efficiently.

The protein found in dairy foods also contributes to calcium absorption and the maintenance of bone density, making them particularly advantageous for athletes who require strong bones for optimal performance and to prevent fractures. Furthermore, dairy sources typically come with additional nutrients, such as vitamin D, which further aids calcium absorption in the body.

While leafy greens, legumes, and nuts do contain calcium, they also include compounds such as oxalates and phytates that can inhibit calcium absorption. Thus, even though these foods can be part of a well-rounded diet, they do not provide calcium in the same readily absorbable manner as dairy products do, making dairy the preferred choice for athletes seeking to meet their calcium needs effectively.
