Caffeine is a popular stimulant found in many beverages and foods. While it can boost energy and alertness, excessive intake might affect bone health. Studies suggest that high levels of caffeine (over 744 milligrams per day) can increase the amount of calcium and magnesium lost through urine. These minerals are crucial for maintaining strong bones. However, you can offset some of this loss by adding a small amount of milk to your coffee. Some research also links high caffeine intake to an increased risk of hip fractures, particularly in older adults. Therefore, it's wise to monitor your caffeine consumption and consult your doctor, especially if you have concerns about osteoporosis or bone health.
