- Texas A&M University researchers found that adults ages 45–65 taking 10 grams of creatine monohydrate daily gained roughly 2.4 pounds of lean tissue and improved leg press and bench press strength over 12 weeks without any structured exercise program
- Participants who combined creatine with resistance and aerobic training three times per week plus a modest calorie deficit added nearly three pounds of lean tissue while also losing fat mass
- The study, published in the Journal of the International Society of Sports Nutrition, enrolled 64 healthy adults and is the first to show that adding creatine to an exercise-and-diet weight-loss program reduces body fat percentage more than exercise and diet alone
- Creatine did not improve aerobic capacity beyond the gains from exercise alone, consistent with prior evidence that it primarily supports muscular strength and power rather than cardiovascular fitness
- Dr. Richard Kreider, director of Texas A&M's Exercise and Sport Nutrition Lab, led the work after more than three decades studying creatine and noted that reaching 10 grams daily from food alone would require eating 5 to 10 pounds of meat or fish
- A 2025 analysis by Kreider's team reviewed 685 clinical trials and found no significant difference in reported side-effect rates between people taking creatine and those receiving a placebo
Why it matters: For adults 45–65 facing age-related muscle loss, a daily 10-gram creatine dose added roughly 2.4 pounds of lean tissue even without hitting the gym, and paired with exercise and a calorie deficit it produced the first documented fat-percentage reduction beyond exercise and diet alone. Backed by a 685-trial safety review showing no significant side-effect difference from placebo, the finding reframes creatine from an athlete's supplement toward a practical aging-well tool.
