New Research Shows Creatine Boosts Strength and Preserves Muscle During Weight Loss
Creatine has long held a reputation as a staple supplement for serious athletes aiming to build muscle and enhance performance. However, recent findings from Texas A&M University suggest that the compound’s advantages extend far beyond the gym, offering notable benefits for middle-aged and older adults working to maintain physical strength and manage their body composition.
Published in the Journal of the International Society of Sports Nutrition, a 12-week study investigated the effects of creatine supplementation on individuals aged 45 to 65. Led by Dr. Richard Kreider, professor and director of the Exercise and Sport Nutrition Lab at Texas A&M, the research explored how a daily dose of creatine influences lean tissue, physical strength, and fat loss, both with and without a structured exercise regimen.
The investigation included 64 healthy adult participants. During the 12-week intervention, participants either engaged in a structured exercise and diet-induced weight-loss program or maintained a non-exercise lifestyle. Within each group, participants were randomly assigned to consume either 10 grams of creatine monohydrate or a placebo daily.
Among the participants who did not partake in the structured exercise program, those taking creatine gained an average of approximately 2.4 pounds, or 1.1 kilograms, of lean tissue over the course of the 12 weeks. Furthermore, this non-exercising group demonstrated measurable improvements in both leg press and bench press strength, illustrating the compound’s potential impact even in the absence of a dedicated workout routine.
For participants who combined supplementation with a structured program—completing resistance and aerobic training three times a week alongside a modest calorie deficit—the benefits were even more pronounced. These individuals experienced greater gains in leg press and bench press strength, as well as an increased time to exhaustion during physical exertion. However, researchers noted that creatine did not significantly alter aerobic capacity, aligning with the supplement’s primary role in enhancing muscular strength and power rather than cardiovascular endurance.
A central challenge in many weight-loss programs is the tendency for the body to shed valuable muscle mass alongside fat. The Texas A&M study addressed this hurdle directly. After 12 weeks of calorie restriction and exercise, participants taking creatine gained nearly three pounds of lean tissue while simultaneously reducing their overall fat mass. Conversely, participants in the exercise-and-diet group who received a placebo showed minimal change in lean tissue. Additionally, the creatine group achieved a significantly greater reduction in overall body fat percentage.
Dr. Kreider, who has studied creatine for more than three decades, noted that to the researchers’ knowledge, this trial is the first to demonstrate that adding creatine to an exercise and diet-induced weight-loss program can produce superior fat-loss outcomes compared to diet and exercise alone.
While the human body naturally produces creatine, and the compound can be found in dietary sources such as red meat and fish, obtaining an equivalent daily dose through food alone is often impractical. Dr. Kreider pointed out that an individual would need to consume between five and 10 pounds of meat or fish daily to reach 10 grams of creatine, positioning supplementation as a more accessible and economical alternative.
Safety remains a primary consideration when evaluating nutritional supplements. Creatine stands as one of the most thoroughly investigated sports supplements in history. A comprehensive 2025 analysis led by Dr. Kreider and his colleagues reviewed 685 clinical trials and found no significant differences in reported side effects between individuals taking creatine and those taking a placebo, reinforcing its strong safety profile for broader populations.
