Daily creatine supplementation might be beneficial for middle-aged and older individuals by helping them maintain lean muscle mass, enhance strength, and even support cognitive function, whether or not they exercise. This is based on a study published in the Journal of the International Society of Sports Nutrition.
The 12-week study, carried out by researchers at Texas A&M University’s Exercise & Sport Nutrition Lab, involved 64 participants aged 45 to 65. They were split into two groups: those who did not exercise and those who combined exercise with dietary changes. Participants were randomly assigned to receive either 10 grams of creatine monohydrate daily—given in two doses of 5 grams each—or a placebo.
Creatine, as the Cleveland Clinic explains, is a compound that helps cells regenerate adenosine triphosphate (ATP), which is crucial for energy in muscle and brain tissues. The supplement enables muscles to produce quick energy for strength training activities.
As people age, they tend to naturally lose muscle mass and strength, a condition referred to as sarcopenia. While dieting can further accelerate this loss, the study’s findings suggest that creatine monohydrate may mitigate those effects.
Those who combined creatine with a regimen of exercise and dieting saw more significant reductions in body fat percentage, better preservation of lean body mass, and marked improvements in both upper- and lower-body strength compared to those who received a placebo. Interestingly, even participants who did not exercise noticed an increase in lean tissue mass and improvements in muscular strength and endurance.
Jacob Zemer, a fitness coach based in New York, noted that the ability to increase lean muscle mass without working out is quite remarkable, especially as one ages. He mentioned that the mental and physical benefits suggest many might want to consider creatine supplementation. He pointed out that even those who didn’t exercise reported gains in exercises like the bench press and leg press.
Zemer further explained that the study hints at the idea that creatine may encourage the development of actual muscle tissue rather than just increasing the water content in muscle cells. Beyond physical benefits, the researchers also observed improved memory and cognitive processing from the daily 10-gram dose.
While creatine has clear benefits as adults age, experts emphasize that it is meant to complement, not replace, the advantages of regular exercise. Zemer clarified that simply boosting muscle mass with creatine, without any exercise, isn’t the best approach.
He firmly believes exercise provides fundamental benefits that surpass those of creatine alone, and when both are used together, the results are significantly enhanced.
However, the study isn’t without its limitations. Participants self-selected into the exercise or non-exercise groups before being randomly assigned to receive either creatine or a placebo—this could lead to lifestyle differences affecting results. Plus, the 12-week duration and focus solely on healthy adults do not offer insights on long-term effects or implications for individuals with serious health conditions.
Zemer recommends consulting a healthcare professional before considering creatine supplementation, choosing a reliable brand, maintaining hydration, and sticking to a routine. He mentioned that standard recommended doses often range from 3 grams for women to 5 grams for men, although this study utilized higher amounts. He emphasizes consistency in taking it, regardless of the timing.
According to the NIH Office of Dietary Supplements, creatine is generally safe for healthy adults, but some might experience side effects like bloating or stomach discomfort. As always, individuals with chronic health issues—such as kidney disorders—should consult their doctors before starting any supplementation.
