How one simple compound supports both your strength and your cognition.
At Central Ohio Spine and Joint, we often talk about the foundations of long-term health — strength, mobility, and resilience. But there’s one supplement that consistently proves its value across both body and mind: creatine.
Most people associate creatine with bodybuilders or athletes looking to pack on muscle. But the science over the past two decades paints a much bigger picture. Creatine doesn’t just help you lift heavier — it can also improve energy production inside your brain, support recovery, and even protect cognitive performance as you age.
Let’s break down what creatine actually is, how it works, and why it’s one of the most evidence-backed supplements you can take to build both muscle strength and brain power.
What Is Creatine?
Creatine is a naturally occurring compound made from amino acids and stored mainly in your muscles. It plays a crucial role in producing energy during high-intensity, short-duration movements — like sprinting, lifting, or explosive power work.
Inside your body, creatine is converted into phosphocreatine, which serves as a rapid energy reserve to regenerate ATP (the body’s energy currency). The more phosphocreatine you have available, the longer and harder you can sustain high-effort exercise before fatigue sets in.
Your body produces some creatine naturally, and you can also get small amounts from foods like red meat and fish. But supplementation helps “fill the tank,” allowing you to maximize your energy stores — not only in your muscles but also in your brain.
Creatine for Muscle Strength and Growth
Why It Works
When paired with resistance training, creatine helps you:
- Train harder and longer – By replenishing ATP faster, you can push through extra reps and sets.
- Recover faster – Less energy depletion means reduced fatigue and better workout quality.
- Trigger growth signals – Creatine increases water retention within muscle cells, which helps stimulate protein synthesis.
- Increase lean muscle mass – Over time, this combination of improved training and recovery leads to measurable hypertrophy.
The Research Is Clear
Hundreds of studies — and multiple meta-analyses — confirm creatine’s role in improving muscular performance and body composition:
- A 2024 meta-analysis of adults under 50 found that creatine plus resistance training significantly increased both upper and lower body strength compared to training alone.
- A 2022 review reported consistent gains in muscle size and performance among both trained and untrained adults supplementing with creatine.
- Even older adults have shown improved strength and power when creatine is combined with progressive resistance exercise.
How to Take It for Muscle Health
- Daily dose: 3–5 grams per day of creatine monohydrate (the most studied form).
- Loading phase (optional): 20 grams per day for 5–7 days, then 3–5 grams daily.
- Timing: Consistency matters more than timing. Many choose to take it post-workout with a protein or carb source to enhance absorption.
- Hydration: Drink adequate water — creatine helps pull fluid into muscle cells, which is beneficial but requires proper hydration.
Creatine won’t “make” muscle on its own — it amplifies your ability to train effectively. In short: if you lift consistently, creatine helps you get more from every workout.
Creatine for Cognitive Function and Brain Health
Beyond the Gym: Fueling the Brain
The human brain is one of the most energy-demanding organs in the body. Just like your muscles, it relies on ATP to function efficiently — for focus, memory, and mental processing.
Creatine helps buffer the brain’s energy system, particularly during times of stress, sleep deprivation, or aging. By improving cellular energy availability, creatine may support:
- Memory and recall
- Processing speed and reaction time
- Mental clarity under fatigue
- Neuroprotection against energy deficits
The Emerging Research
Recent studies suggest a powerful link between creatine and cognitive performance:
- A 2024 meta-analysis found that creatine supplementation significantly improved memory and processing speed in adults, especially under cognitive stress.
- Additional research shows that vegetarians, older adults, and sleep-deprived individuals may experience the greatest benefits — likely due to lower baseline creatine stores.
- While results in young, healthy adults are mixed, the overall trend points toward creatine’s ability to enhance brain energy metabolism and protect against cognitive decline over time.
How to Take It for Brain Health
The dosage for cognitive benefits mirrors that for muscular benefits — 3–5 grams daily. Because brain tissue responds more slowly to supplementation than muscle, consistency is even more critical. Expect potential improvements after several weeks of use.
Those who may benefit most include:
- Adults over 50
- Vegetarians and vegans
- Individuals under chronic stress or sleep deprivation
- Athletes balancing heavy physical and mental workloads
Safety and Side Effects
Creatine monohydrate is one of the most researched supplements in history — with over 1,000 studies supporting its safety and efficacy.
Key points:
- Safe for long-term use in healthy individuals
- Minor side effects (if any) include mild water retention or temporary stomach discomfort
- No proven link to kidney or liver damage in healthy users
- Always consult your healthcare provider if you have pre-existing kidney issues or are taking medication
At COSJ, we emphasize science-backed supplementation as part of an integrated approach to health — not as a replacement for quality nutrition, movement, and recovery.
Who Should Consider Creatine
You may benefit from creatine if you:
- Strength train or perform high-intensity exercise regularly
- Want to maintain or increase lean muscle mass
- Experience fatigue or reduced cognitive sharpness
- Follow a vegetarian or low-meat diet
- Are over 50 and focused on preserving strength and cognition
You may see less impact if you:
- Rarely perform resistance training
- Already have a high dietary creatine intake (e.g., frequent red meat consumption)
- Are inconsistent with supplementation or hydration
Common Myths About Creatine
Myth 1: Creatine causes bloating or fat gain.
False. The slight increase in weight comes from water inside the muscle cells — not fat. This “cell hydration” actually helps stimulate muscle growth.
Myth 2: It’s only for bodybuilders.
Creatine benefits anyone who wants to move better, think clearer, and age stronger — not just competitive athletes.
Myth 3: It’s bad for your kidneys.
No evidence supports this in healthy populations. In fact, long-term studies (over a decade) confirm its safety when used as directed.
The Bottom Line
Creatine isn’t just about performance — it’s about longevity. It supports the very systems that keep you strong, mobile, and mentally sharp.
At Central Ohio Spine and Joint, we encourage our patients and clients to view creatine as more than a “gym supplement.” It’s a scientifically proven way to:
- Build and preserve lean muscle
- Support recovery and training quality
- Enhance brain energy and cognitive resilience
Whether you’re a weekend warrior, a busy professional, or someone looking to age with strength — creatine can be a small daily step toward a stronger, sharper you.
Key Takeaway
Creatine builds muscle. It strengthens the brain. And when combined with proper training and nutrition, it helps you stay stronger, longer.
