Creatine has been studied more extensively than almost any other supplement. The research spans decades and hundreds of trials. And yet, most people outside the gym world have never considered taking it.
That's a missed opportunity.
What Creatine Actually Is
Creatine is a naturally occurring compound synthesized in the liver, kidneys, and pancreas from three amino acids. It's stored primarily in muscle tissue as phosphocreatine, where it serves as the fastest energy reserve available to cells — providing ATP (cellular energy) in the first 10–15 seconds of high-intensity effort.
But muscle isn't the only place creatine matters.
The Brain Health Case
The brain has high energy demands and can become energy-depleted under stress, sleep deprivation, cognitive load, and aging. Creatine supplementation has been shown to increase brain creatine levels and supports cognitive performance under demanding conditions, particularly tasks requiring working memory and speed of processing.
Research on creatine for cognitive decline, traumatic brain injury recovery, and age-related mental fatigue is growing rapidly. This is the angle most people haven't heard.
The Muscle and Aging Case
Sarcopenia — age-related muscle loss — begins in the 30s and accelerates after 60. Creatine supplementation combined with resistance exercise is one of the most evidence-based interventions for preserving muscle mass and function with age. It also supports bone density in older adults and improves the anabolic response to training at any age.
The Most Common Myths
"It makes you bloated." Creatine draws water into muscle cells, which is the mechanism behind its performance benefits. Subcutaneous water retention is not typical with modern monohydrate at standard doses.
"It's only for young men." Women, older adults, and non-athletes show robust benefits in the research, particularly for cognitive function and healthy aging.
"You need to load it." A loading phase speeds saturation but isn't necessary. 3–5g daily reaches effective tissue saturation within 3–4 weeks.
What We Recommend
Creatine monohydrate is the form with the most research by a significant margin. Look for third-party tested products with no fillers. 3–5g daily, any time of day, taken consistently is the protocol.
