Taking Daily Creatine May Help Preserve Muscle as You Age--Even without Exercise

Daily creatine supplementation could help middle-aged and older adults preserve lean muscle mass, gain strength and support cognitive function, whether it's paired with exercise or not, according to a study published in the Journal of the International Society of Sports Nutrition.

The 12-week study, conducted by researchers at Texas A&M University’s Exercise & Sport Nutrition Lab, evaluated 64 men and women ages 45 to 65.

Participants were divided into non-exercise and exercise-plus-diet groups, then randomly assigned to take either 10 grams of creatine monohydrate per day — administered in two 5-gram doses — or a placebo.

Adults naturally lose muscle mass and strength as they age, a condition known as sarcopenia. While dieting can accelerate that muscle loss, the new study found that creatine monohydrate helped counter the effect.

Adding creatine to an exercise and diet intervention resulted in greater reductions in body fat percentage, better preservation of lean body mass, and marked improvements in upper- and lower-body strength compared to a placebo.

Even among participants who did not engage in exercise or dietary changes, daily creatine supplementation increased lean tissue mass and improved muscular strength and endurance, according to the study.

"The fact that you can increase lean muscle mass even without exercise is remarkable, especially as we age," New York-based fitness coach Jacob Zemer told Fox News Digital. "Between the physical and mental benefits, most people should be considering creatine supplementation."

The expert, who was not involved in the study, noted that even participants who did not exercise saw an increase in their bench press and leg press.

Beyond physical performance, the researchers found that the 10-gram daily dose of creatine supported improvements in select tests of memory and cognitive processing.

"My main takeaway from the study is that the benefits of creatine extend far beyond just athletes and bodybuilders," Zemer said. "Creatine continues to be the most scientifically studied and validated supplement on the market."
