New Research: Creatine Isn't Just for Muscles Anymore

A 2025 meta-analysis reveals surprising cognitive benefits that could change how we think about this classic supplement.

For decades, creatine has been the go-to supplement for athletes and gym-goers looking to build muscle and improve strength. But emerging research suggests we've been underestimating this compound's potential

A comprehensive 2025 meta-analysis examining 16 randomised controlled trials has found that creatine supplementation produces significant improvements in cognitive function — specifically in memory, processing speed, and attention.

The Science Behind Brain Energy

Your brain is an energy-hungry organ. Despite making up only about 2% of your body weight, it consumes roughly 20% of your total energy. This is where creatine comes in.

Creatine's primary role is to help transport energy within cells. In the brain, this means supporting the rapid ATP regeneration needed for demanding cognitive tasks — everything from problem-solving to maintaining focus during long work sessions.

What the Research Actually Shows

The meta-analysis, which included 492 participants aged 20 to 76, found statistically significant improvements in three key areas:

• Memory performance — Enhanced ability to retain and recall information
• Processing speed — Faster cognitive response times‍
• Attention — Improved ability to maintain focus

Perhaps most interesting: the benefits appeared strongest in adults aged 18-60 and in individuals experiencing cognitive stress — such as sleep deprivation or demanding mental workloads.

Who Might Benefit Most

Based on the current evidence, creatine supplementation may be particularly valuable for:

• Professionals working long or irregular hours
• Frequent travellers dealing with jet lag and disrupted sleep
• Anyone regularly operating under mental fatigue
• Adults looking to support cognitive function as they age

‍

The Practical Takeaway

While creatine has long been recognised as safe and effective for physical performance, this research suggests its applications extend well beyond the gym. For men over 35 juggling demanding careers, family responsibilities, and the natural cognitive changes that come with age, creatine represents a well-researched option worth considering.

The typical dosage used in cognitive research is 3-5 grams daily — the same amount commonly recommended for athletic performance.

As always, quality matters. Look for creatine monohydrate from reputable sources with third-party testing.
