Creatine Isn't Just for Athletes Anymore: Why More Adults Are Taking It for Strength, Brain Health, and Healthy Aging

When most people hear the word creatine, they picture bodybuilders, protein shakes, and intense gym workouts.

But that's no longer the full story.

While creatine has been one of the most researched sports supplements in the world for decades, scientists are now discovering benefits that extend far beyond building muscle. Researchers are studying creatine's role in brain health, cognitive performance, healthy aging, sleep deprivation, and even resilience during travel and jet lag.

In a recent interview on The Diary of a CEO, leading creatine researcher Dr. Darren Candow discussed why creatine may be one of the most valuable supplements available. It’s not just for athletes, but for anyone who wants to support their physical and mental performance as they age. (see below for the full interview on YouTube)

It All Starts with Energy

At its core, creatine helps your body produce energy.

Every cell in your body requires energy to function, but some tissues have especially high energy demands. Your muscles need energy to lift weights, climb stairs, and carry groceries. Your brain needs energy to think, focus, solve problems, and process information throughout the day.

Creatine helps replenish your body's energy stores, allowing both your muscles and your brain to perform more efficiently when demands are high.

This is why creatine has become so popular in the fitness world. Study after study has shown that creatine can improve strength, power output, exercise performance, and lean muscle mass when combined with resistance training. Whether you're trying to improve your CrossFit  or Bootcamp performance, stay active with your kids, or simply maintain your strength as you age, creatine can help you get more from the work you're already doing.

The Brain Health Benefit Most People Don't Know About

What makes the current research so exciting is what we're learning about the brain.

Your brain uses an incredible amount of energy every day. Researchers now believe that increasing creatine stores may help support cognitive function, memory, focus, and mental performance particularly during periods when the brain is under greater stress.

This is one of the reasons creatine has become a hot topic in conversations around longevity and healthy aging. While research is ongoing, the evidence suggests that creatine's benefits may extend well beyond the gym.

Can Creatine Help When You're Sleep Deprived?

Let's be honest: most adults don't get enough sleep.

Between work responsibilities, parenting, travel, and busy schedules, many people spend at least part of the year running on less sleep than they would like.

While creatine is certainly not a replacement for proper sleep, emerging research suggests it may help support cognitive performance during periods of sleep deprivation. Some studies have shown that individuals who supplement with creatine may experience less mental fatigue and better cognitive function when sleep is limited.

That's particularly interesting for busy professionals, parents of young children, healthcare workers, shift workers, first responders, and anyone navigating a demanding schedule.

What About Travel and Jet Lag?

Researchers are also exploring creatine's potential role during travel and jet lag.

Anyone who has traveled across multiple time zones knows the feeling: brain fog, sluggishness, difficulty concentrating, and a general sense that your body and mind aren't operating at full capacity. Because creatine supports cellular energy production, scientists are investigating whether it may help the brain better manage the stress associated with disrupted sleep and long-distance travel.

Again, creatine isn't a magic solution, but the possibility that a simple supplement could support both physical and mental performance during these challenging situations is one reason interest in creatine continues to grow.

Why Creatine Matters Even More as We Age

Perhaps the most important application, however, may be healthy aging.

As we get older, maintaining muscle mass becomes increasingly important. Strength supports balance, mobility, bone health, metabolic health, and overall independence. Losing muscle as we age isn't just about looking different. It's one of the biggest factors affecting our quality of life.

Research consistently shows that combining resistance training with creatine supplementation can help support muscle mass and strength as we age. At the same time, researchers continue to investigate creatine's potential role in supporting brain health and cognitive function throughout the aging process.

For many adults, that's a powerful combination: supporting both physical and mental performance with a supplement that has been studied for decades.

Is Creatine Safe?

One of the questions we hear most often at CrossFit Winter Park is whether creatine is safe.

The good news is that creatine monohydrate is one of the most extensively researched supplements available today. Decades of research have consistently demonstrated its safety for healthy individuals when used as directed. For most adults, a daily serving of 5 grams of creatine monohydrate is the standard recommendation used throughout the research. But, we now know that higher doses may be beneficial for the brain and skeleton as well.

Why We Recommend Thorne

Of course, quality matters.

The supplement industry is not regulated as tightly as many people assume, and products can vary significantly in purity and manufacturing standards. That's why we partner with Thorne, a company known for its commitment to rigorous testing, quality control,  and third-party and NSF Certifications.

The Bottom Line

Creatine is no longer just a supplement for athletes.

Whether your goal is building strength, preserving muscle as you age, supporting brain health, improving recovery, staying sharp during demanding periods of life, or simply investing in your long-term health, creatine is one of the most evidence-backed supplements available today.

At CrossFit Winter Park, we've seen growing interest in creatine from competitive athletes, busy professionals, parents, and adults over 50 alike. As the research continues to evolve, one thing is becoming increasingly clear: supporting your body's ability to produce energy may be one of the smartest investments you can make in both your physical and mental performance.
