Creatine monohydrate benefits and research overview

Creatine monohydrate is a widely studied supplement primarily known for enhancing performance during high-intensity resistance training and sprint-type exercises by increasing muscle phosphocreatine and regenerating ATP.

Common usage involves a maintenance dose of 3 to 5 grams daily, though a loading phase of approximately 20 grams per day for 5 to 7 days can saturate muscle stores more quickly. While generally well-tolerated by healthy adults, individuals with kidney disease, those who are pregnant, or adolescents should seek medical guidance.

Emerging research is exploring the potential benefits of creatine for brain health, including memory, mood, and focus. While biologically plausible due to the brain's high energy demands, current human evidence remains early and mixed. Studies suggest creatine may support cognitive performance during specific metabolic stressors such as sleep deprivation, mental fatigue, or hypoxia, but more research is required before it can be categorized as a proven nootropic for healthy adults.
