Medical discussions regarding creatine supplementation have focused on its physiological effects and its impact on clinical diagnostic accuracy. Initial concerns highlighted how creatine use can lead to elevated creatinine levels in blood tests, which can cause misinterpreted results in healthy individuals regarding kidney health. Scientific review has addressed the supplement’s broader applications and common misconceptions. Creatine is recognized for enhancing energy during high-intensity exercise, aiding muscle recovery, and combating sarcopenia in elderly or intensive care patients. Evidence suggests that when taken at recommended doses, it does not cause hair loss, increased body fat, or kidney damage in healthy users. While it may cause slight weight gain through muscle water retention, research does not support claims linking human consumption to cancer or metastasis. Recent research continues to emphasize these benefits, noting that when combined with resistance training, supplementation can significantly improve muscle strength in both upper and lower body regions. Emerging research is also investigating potential cognitive benefits, such as improvements in memory and brain function. A 12-week ~~double-blind trial~~ study from Texas A&M University, published in the Journal of the International Society of Sports Nutrition, involving 64 adults aged 45 to 65, found that daily creatine supplementation may increase lean muscle mass and strength even in sedentary individuals. Participants receiving 10 grams of daily creatine showed increases in lean mass—including muscle, water, and organs—and improved performance in strength tests, such as bench press and leg press, without additional exercise. These sedentary participants gained approximately 1.1 kilograms of lean tissue compared to the placebo ~~group, despite relatively low protein intake.~~ group. For those who modified diet and activity, supplementation was associated with greater reductions in body fat percentage and more significant improvements in strength and endurance. ~~Physiologically, creatine works by increasing muscle stores of phosphocreatine to aid ATP production.~~
