What is the daily calcium requirement for individuals aged 9-30 years?

The daily calcium requirement for individuals aged 9-30 years is 1300 mg. This requirement is based on the need for adequate calcium intake during periods of rapid growth and development, especially during adolescence and early adulthood. Calcium is essential for building and maintaining strong bones and teeth, and it plays a crucial role in various metabolic functions.

Adolescents and young adults are in a critical stage for bone development, as peak bone mass is typically achieved by the mid-20s. Ensuring that individuals in this age group consume sufficient calcium is important for long-term bone health, reducing the risk of osteoporosis and fractures later in life.

While some other values exist for different age ranges or specific populations, the 1300 mg recommendation is established through various health guidelines and research studies that emphasize the importance of calcium intake during these formative years. The higher requirement underscores the increased nutritional needs during adolescence compared to earlier or later life stages.
