CREATINE
REDEFINED
Most creatine is cheap because the process is dirty. BrainTree Creatine uses Pürest Creatine™ — the only form that consistently tests among the lowest impurity levels on the global market. Cleaner creatine means more of it reaching your brain and body.
CREATINE
DONE RIGHT
Creatine monohydrate is the most researched supplement in sports nutrition history — over 500 peer-reviewed studies. The problem was never the molecule. It was always the manufacturing. BrainTree Nutrition solves that.
THE MOST
RESEARCHED SUPPLEMENT
IN EXISTENCE
Creatine monohydrate has over 500 peer-reviewed studies and decades of real-world use. It supports brain energy metabolism, memory, and cognitive performance — and separately, it is the only supplement the International Society of Sports Nutrition designates as the most effective ergogenic nutritional supplement available for increasing high-intensity exercise capacity and lean body mass. Brain and body.
It works by replenishing phosphocreatine stores in muscle — the fuel system for explosive, high-intensity efforts. When your ATP runs out in seconds, phosphocreatine is what keeps you going. More creatine means more fuel available, more reps, more output, and faster recovery between sets.
More recently, the research has expanded beyond muscle: creatine crosses the blood-brain barrier, supports brain energy metabolism, and has been shown in multiple trials to improve memory, executive function, and cognitive performance — particularly under stress or sleep deprivation.
Based on aggregated data across published meta-analyses of creatine monohydrate supplementation.
BRAIN FIRST.
THEN BODY.
Creatine crosses the blood-brain barrier and supports cerebral phosphocreatine levels. A 2024 meta-analysis of 16 RCTs found positive effects on overall cognitive function, memory, and executive function. A 2024 study in Scientific Reports showed a single dose improved cognitive performance during sleep deprivation.
Emerging research supports creatine for healthy aging — neuroprotection, cognitive preservation, and slowing age-related cognitive decline. 5/6 studies in a 2024 systematic review found positive relationships between creatine and cognition in older adults, particularly in memory and attention.
Creatine increases intramuscular phosphocreatine stores, directly enabling more ATP resynthesis during high-intensity efforts. Meta-analyses consistently show 8–14% improvements in strength vs placebo across resistance training studies — the most reproducible effect in sports nutrition.
Sprint capacity, repeated effort performance, and total work output all improve with creatine loading. The effect is most pronounced in activities lasting 6–30 seconds — the exact window of phosphocreatine metabolism. More reps, more power, better output every set.
Creatine is the rate-limiting substrate for phosphocreatine resynthesis — in both muscle and brain. Between explosive efforts, higher creatine stores mean faster restoration of the phosphagen system, reducing fatigue and maintaining power and mental sharpness across extended output.
Creatine promotes intracellular water retention in muscle cells, supporting cellular hydration and thermoregulation. This osmotic effect also contributes to the volumizing appearance associated with creatine loading and may support muscle protein synthesis signaling pathways.
500+ STUDIES.
THE DATA IS IN.
Creatine monohydrate is not an emerging ingredient. It is the most studied performance supplement in history. Here is what the peer-reviewed literature consistently shows — brain first.
Creatine's role in the brain is one of the most significant developments in sports nutrition research. The brain is an energy-intensive organ — accounting for ~20% of total body energy use. Phosphocreatine in the brain serves the same ATP-buffering function as in muscle. Creatine supplementation has been shown to increase brain phosphocreatine levels and improve multiple domains of cognitive function in human trials.
Creatine monohydrate's effect on strength and power output is the most replicated finding in sports nutrition. The International Society of Sports Nutrition designates it the most effective ergogenic supplement available for increasing high-intensity exercise capacity and lean body mass. The mechanism is direct: more phosphocreatine means more ATP availability during maximal efforts.
NOT ALL CREATINE
IS EQUAL
The molecule is the same. The manufacturing is not. Most brands source the cheapest creatine available and never verify what's in it. BrainTree sources the highest-purity form on the market and tests every batch.

THE MOST
UNIVERSAL SUPPLEMENT
Creatine's cognitive benefits are increasingly well-documented — memory, executive function, and processing speed all respond positively in RCTs. The brain uses ~20% of your body's energy. Creatine keeps that system stocked. The gym benefits are a bonus.
More phosphocreatine. More ATP. More reps, more weight, more volume. The mechanism is direct and the evidence is overwhelming — creatine is the single most effective supplement for resistance training output.
Repeated sprint capacity, power between efforts, and reduced fatigue index all improve with creatine supplementation. Every explosive action in a game draws on the phosphagen system — creatine keeps that system stocked.
Dietary creatine comes almost exclusively from meat. Vegans and vegetarians have significantly lower baseline creatine stores in both muscle and brain — and show the largest cognitive and physical gains from supplementation.
5/6 studies in a 2024 systematic review found positive cognitive effects in older adults. Combined with resistance training, creatine also preserves muscle mass, strength, and bone density. A rare supplement that supports both brain and body aging simultaneously.
If you care enough to read labels and look up ingredients, you'll appreciate Pürest Creatine™. Ultra-low DCD, DHT, and cyanide. Heavy metal compliant. COA every lot. You can actually verify what you're putting in your body.
PURITY IS THE
WHOLE POINT
All creatine monohydrate starts as the same molecule. What separates them is manufacturing — specifically, the impurities generated during synthesis. Most brands source the cheapest available creatine. BrainTree sources the highest-purity form on the market and tests every batch.
