Dr. Andy Galpin on Creatine: Strength, Power, and Lifelong Performance
|
Creatine is one of the most researched supplements in sports nutrition, yet it remains widely misunderstood. Often associated only with bodybuilding or short-term strength gains, creatine is frequently overlooked for its broader benefits across performance, cognitive health, and healthy aging.
Dr. Andy Galpin, Ph.D., CSCS*D, NSCA-CPT*D, FNSCA, is Professor & Director of the Human Performance Center at Parker University in Dallas, Texas. He has spent years translating complex exercise science into practical guidance for athletes and everyday active people alike.
Across academic research, elite sport consulting, and long-form podcast discussions—including the Huberman Lab podcast—Dr. Galpin consistently emphasizes that creatine is not a niche supplement. It is a foundational tool for improving physical capacity and supporting long-term health.
This article compiles Dr. Galpin’s core insights on creatine: what it is, how it works in the body, who benefits most, and why it plays a role far beyond the weight room.
What Is Creatine?
Creatine is a naturally occurring compound made from the amino acids arginine, glycine, and methionine. It is produced in small amounts by the body and is also found in foods like red meat and fish.
Approximately 95% of the body’s creatine is stored in skeletal muscle, where it plays a critical role in rapid energy production. The remaining amount is found in tissues such as the brain, underscoring creatine’s relevance beyond muscular performance.
Dr. Galpin often emphasizes that creatine is not a stimulant or hormone; it is an energy substrate that supports the body’s ability to produce force, repeat high-output efforts, and recover between bouts of work.
How Creatine Works in the Body
Creatine’s primary function is to support the phosphocreatine system, one of the body’s fastest energy pathways. During short, intense efforts, such as sprinting, lifting, or jumping, phosphocreatine helps rapidly regenerate ATP, the body’s primary energy currency.
According to Dr. Galpin, this mechanism explains why creatine consistently improves:
Repeated sprint and high-intensity performance
Training volume and work capacity
By allowing athletes to perform more high-quality reps or sustain power output longer, creatine indirectly supports greater training adaptations over time.
Creatine and Muscle Growth
Dr. Galpin frequently clarifies that creatine does not directly “build muscle” on its own. Instead, it enhances the conditions required for hypertrophy.
Creatine supplementation can:
Increase training intensity and total volume
Improve recovery between sets
Support cellular hydration, which may contribute to muscle growth signaling
Over weeks and months, these effects compound, leading to greater strength gains and lean mass accrual when paired with resistance training.
Beyond Strength: Creatine and Cognitive Performance
One of Dr. Galpin’s most important points is that creatine is not only for muscles. Because the brain also relies on ATP for energy, creatine plays a role in cognitive performance, particularly under stress or fatigue.
Research suggests creatine may support:
Mental performance during sleep deprivation
Cognitive endurance during demanding tasks
Overall brain energy availability
Recovery from traumatic brain injury
Dr. Galpin often highlights creatine as one of the few supplements with evidence supporting both physical and cognitive performance, making it especially relevant for athletes, military personnel, and high-stress professionals.
Creatine for Aging and Long-Term Health
Creatine’s benefits extend well beyond competitive sport. Dr. Galpin frequently discusses its relevance for healthy aging, particularly in preserving strength and function.
As people age, they naturally experience declines in:
Muscle mass
Strength and power
Neuromuscular efficiency
Creatine, when combined with resistance training, has been shown to help older adults:
Maintain lean muscle mass
Improve strength and functional capacity
Support independence and quality of life
From Dr. Galpin’s perspective, creatine is not a “young athlete” supplement, it is a lifespan supplement.

Is Creatine Safe?
Creatine is one of the most extensively studied supplements in the world. According to Dr. Galpin, the scientific consensus is clear: creatine monohydrate is safe for healthy individuals when used at evidence-based doses.
Long-term studies show no negative effects on:
Kidney function in healthy populations
Hydration status
Muscle cramping or injury risk
Dr. Galpin emphasizes that misinformation around creatine safety persists largely due to outdated or misinterpreted data, not current research.
How Much Creatine Do You Need?
Dr. Galpin typically recommends a simple, consistent dosing approach rather than complex loading protocols.
General guidance aligns with:
3–5 grams of creatine monohydrate per day
Daily use, including rest days
No cycling required
Consistency matters more than timing. Whether taken pre- or post-workout, the goal is to saturate muscle creatine stores over time.
Dr. Andy Galpin × Momentous Creatine
Dr. Galpin partners with Momentous because the brand’s creatine meets the standards required for both elite athletes and evidence-driven consumers.
Momentous Creatine Monohydrate is formulated with:
Creapure® creatine monohydrate for purity and consistency
No fillers or additives
Third-party testing for quality and safety
NSF Certified for Sport
Momentous also offers creatine in two other formats: 15-Travel Packs and Momentous Creatine Chews.
Each chew delivers 1 gram of pure Creapure® creatine monohydrate—the most trusted, rigorously tested form on the market—backed by 30+ years of research and NSF for Sport® certification for unmatched purity, potency, and safety.
Designed for everyday performance and convenience, Momentous reimagined creatine in a portable chew that makes daily use effortless—no shaker, no mixing, no compromise. Creatine Chews are now available in three flavors: lemon lime, mango, and strawberry.
For Dr. Galpin, creatine supplementation is not about shortcuts—it is about supporting the fundamental physiology of performance. When combined with proper training, nutrition, sleep, and recovery, creatine helps athletes and active people train harder, adapt better, and maintain strength and performance across their lifespan.
