Young athletes are advised to increase their calcium intake to what level to help prevent stress fractures?

Young athletes are advised to increase their calcium intake to 1,500 mg per day to help prevent stress fractures. This recommendation is based on the critical role calcium plays in bone health, especially during the formative years of adolescence when bone density is rapidly developing. Adequate calcium intake is essential for maintaining strong bones, and higher levels are needed for individuals who are more physically active, as intense exercise can increase the risk of stress injuries.

The recommendation of 1,500 mg/day considers the elevated nutritional demands placed on young athletes, who not only need to support their growth and development but also the additional stress their bones endure during training and competition. Insufficient calcium intake during this period can lead to lower bone density and an increased risk of fractures, making adequate dietary calcium crucial for maintaining athletic performance and overall health.

Lower levels of calcium, such as 800 mg, 1,000 mg, or 1,200 mg, do not adequately meet the needs of developing athletes, who are encouraged to reach the recommended higher intake to promote optimal bone health.
