Creatine has long been associated with athletic performance and muscle recovery, but researchers are now studying whether it may also support brain health in aging men. A recent article by Dr. Austin Perlmutter highlighted a newly published clinical trial examining creatine supplementation in people with Alzheimer’s disease. While the findings are still preliminary, the study reflects growing scientific interest in how brain metabolism may influence cognitive decline.
Why Brain Metabolism Matters
Creatine is a naturally occurring compound that helps cells produce and store energy. Because muscles require large amounts of energy during physical activity, creatine supplements are commonly used to support exercise performance and recovery. Researchers are now examining whether the brain may benefit from similar energy support.
Alzheimer’s disease is the leading form of dementia worldwide and accounts for roughly 70 percent of dementia cases. Researchers have found that people with Alzheimer’s often experience changes in how the brain processes glucose. These metabolic disruptions may contribute to problems involving memory, focus, and cognitive performance over time. Some scientists have even informally referred to Alzheimer’s as “type 3 diabetes” because of its connection to impaired energy use in the brain.
What the Study Found
The pilot study, published in Alzheimer’s & Dementia: Translational Research & Clinical Interventions, evaluated whether creatine monohydrate supplementation could increase brain creatine levels in people with a high likelihood of Alzheimer’s disease. Participants took 20 grams of creatine monohydrate daily over an eight-week period.
Researchers used advanced MR imaging to measure whether the supplement successfully increased creatine levels inside the brain. The study found that 85 percent of participants experienced increased brain creatine levels, with an average increase of approximately 11 percent. Researchers noted that differences between participants may have been related to how creatine crossed the blood-brain barrier.
The study also evaluated cognitive performance during the eight-week period. Participants demonstrated improvements in several areas, including:
- Overall cognitive scores
- Fluid cognition
- Working memory
- Reading recognition
Researchers observed trends toward improvement in attention and inhibitory control testing.
That being said, not every category improved. The study did not reveal significant changes in certain memory measurements or in the Mini-Mental State Examination, a widely used assessment for cognitive impairment. Researchers emphasized that the study was small and did not include a placebo control group, meaning larger clinical trials are still needed before drawing broader conclusions.
What This Could Mean for Men’s Health
Although the research is still in its early stages, it reflects a growing interest in the relationship between physical fitness, metabolism, and cognitive aging. Researchers are increasingly studying whether maintaining muscle mass, exercise habits, and metabolic health may also support long-term brain function.
For men, this reinforces the importance of taking a proactive approach to aging and overall wellness. Exercise, cardiovascular health, sleep quality, and metabolic function already play major roles in healthy aging. Studies like this suggest those same factors may eventually become more important in conversations surrounding cognitive health.
Supporting Long-Term Wellness
The growing interest in creatine reflects how researchers are increasingly viewing brain health through the lens of metabolism and physical wellness. While creatine supplementation is not a proven treatment for Alzheimer’s disease, studies like this continue expanding conversations around preventive health and aging.
Philadelphia Urology Associates and Dr. Bruce Sloane work with men experiencing many of the metabolic and physical changes that become more common with age, including fatigue, hormone imbalance, and long-term wellness concerns. Working with experienced physicians can help men take a more informed and proactive approach to healthy aging over time.
