Study
Creatine Supplements Improve Muscle and Memory in Older Adults
Taking creatine supplements can help older adults build muscle and enhance memory, whether or not they exercise.
Summary
In plain language
Recent research shows that creatine supplements can be beneficial for adults aged 45 to 65, helping to increase muscle mass and improve cognitive functions like memory. This effect was observed in both those who exercised and those who did not. The study found that, over 12 weeks, participants who took creatine gained more muscle, became stronger, and showed better memory scores. This could be particularly useful for seniors looking to maintain their physical and mental health. These findings suggest that creatine might be a helpful addition to the routine of older adults, but it is always best to discuss any new supplement with a healthcare provider.
Details
Use the full description to understand the study design, methods, and the limits of the findings.
The study was a 12-week trial involving 64 adults aged 45-65. Participants were divided into groups, with some taking creatine and others a placebo, with or without an exercise and diet plan.
The study found that creatine supplementation increased muscle mass, strength, and improved memory, even for those not exercising.
Key findings include a noticeable increase in lean muscle and improvements in cognitive tests among those taking creatine.
While the study showed positive results, it is important to note that individual responses can vary, and more research may be needed to confirm these findings.
For those considering creatine supplements, it's wise to discuss with a healthcare provider to ensure it's a suitable option.

Research Quality Score
Scored October 6, 2026 using rubric mq-1.8_2026-07-06.
Assessment
The study scored highly in study design and bias control due to its rigorous RCT methodology. Transparency was also strong with pre-registration and complete reporting. However, statistical integrity was slightly reduced due to exploratory endpoints without multiplicity adjustment. The conflicts score was low due to the lead author's industry ties, and there was no evidence of replication. The study was highly relevant to the target population, and it was published in a moderately reliable journal.

Additional Notes
This randomized controlled trial investigated the effects of creatine supplementation on body composition, cognitive function, and health markers in middle-aged and older adults, with and without exercise and diet interventions. Results showed improvements in lean mass, strength, and cognitive markers.

Conditions This Research Covers
These condition pages help connect the paper back to the real-world health concerns it addresses.
Dementia
Dementia is a broad term used to describe a decline in cognitive function that interferes with daily life. It predominantly affects older adults, with symptoms like memory loss and changes in behavior. Dementia is not a normal part of aging, and early diagnosis is crucial for management.
Frailty
Frailty is a medical condition common among older adults, marked by decreased strength, endurance, and overall resilience. It increases vulnerability to illness, falls, and slower recovery from health challenges. With early detection, proper nutrition, and targeted exercise, frailty can be managed or even reversed.
