Creatine, a naturally occurring compound found in muscle cells, plays a pivotal role in energy production during high-intensity activities. Beyond its well-known benefits for physical performance, emerging research suggests that creatine supplementation may also enhance cognitive function. This article explores the multifaceted advantages of creatine, its safety profile, recommended dosages, and its potential role in both athletic and cognitive enhancement.

Creatine Supplement

What is Creatine?

Creatine is synthesized in the liver, kidneys, and pancreas from amino acids such as glycine, arginine, and methionine. Approximately 95% of the body’s creatine is stored in skeletal muscles, with the remaining 5% distributed in the brain, liver, kidneys, and testes. In muscles, creatine combines with phosphate to form phosphocreatine, which serves as a rapid energy reserve during short bursts of intense physical activity.
Benefits of Creatine Supplementation

Enhanced Physical Performance

Creatine is renowned for its ability to improve strength, increase lean muscle mass, and aid muscle recovery during exercise. It enhances the phosphocreatine stores in muscles, allowing for greater ATP production, which is crucial for high-intensity training. Studies have shown that creatine users can gain an extra 2.4 pounds of lean muscle and lose 1.5 pounds more fat than non-users.

Cognitive Function Improvement

Beyond physical benefits, creatine supplementation has been associated with cognitive enhancements. A systematic review of randomized controlled trials indicated that creatine administration might improve short-term memory and intelligence/reasoning in healthy individuals. However, results for other cognitive domains, such as long-term memory and attention, were inconsistent.
Additionally, a study published in Scientific Reports found that high doses of creatine could provide a cognitive boost individuals, suggesting its potential role in supporting cognitive function under stress.

Potential Neuroprotective Effects

Creatine’s role in energy metabolism suggests it may offer neuroprotective benefits. By maintaining ATP levels, creatine could help protect neurons from energy depletion and oxidative stress, factors implicated in neurodegenerative diseases. While more research is needed, these properties position creatine as a potential adjunct therapy for conditions like Parkinson’s and Huntington’s diseases.

Cognitive Performance in Sleep-Deprived Individuals with Creatine

Research suggests that creatine supplementation may offer significant cognitive benefits for individuals experiencing sleep deprivation. Sleep deprivation often impairs cognitive functions such as memory, focus, and decision-making due to reduced energy availability in brain cells. Creatine, a naturally occurring compound that supports ATP (adenosine triphosphate) production, helps replenish the brain’s energy reserves, mitigating the cognitive decline associated with sleep loss. Studies have shown that sleep-deprived individuals who supplement with creatine demonstrate improved reaction times, working memory, and problem-solving abilities compared to those who do not. This makes creatine an attractive supplement for individuals in high-pressure environments, such as shift workers, students, or athletes, who often face periods of inadequate sleep yet need to maintain mental clarity and performance.

Recent double-blind, placebo-controlled studies have investigated the impact of creatine supplementation on cognitive performance during sleep deprivation. For instance, a study by McMorris et al. (2006) examined the effects of creatine on cognitive and psychomotor performance, mood state, and plasma concentrations of catecholamines and cortisol after 24 hours of sleep deprivation combined with mild exercise. The findings indicated that participants who received creatine supplementation exhibited significantly less decline in random movement generation, choice reaction time, balance, and mood state compared to the placebo group.

Additionally, a more recent study by Gordji-Nejad et al. (2024) explored the effects of a single dose of creatine on cognitive performance and cerebral high-energy phosphates during sleep deprivation. This double-blind trial demonstrated that creatine supplementation improved cognitive performance and induced changes in cerebral high-energy phosphates, suggesting a potential mechanism for its cognitive benefits under sleep-deprived conditions.

Safety and Efficacy

Creatine is one of the most extensively studied dietary supplements and is considered safe for long-term use when taken at recommended dosages. Common side effects are rare but may include gastrointestinal discomfort and muscle cramping. It’s important to note that high doses can cause water retention and gastrointestinal issues such as diarrhea.
Individuals with pre-existing kidney conditions should consult healthcare providers before initiating creatine supplementation, as it can temporarily raise creatinine levels, a marker of kidney function. However, this does not indicate kidney health damage when taken in recommended doses (3-5 grams per day).

Dosage and Administration

A common approach to creatine supplementation begins with a loading phase of 20 grams per day, divided into 4 doses, for 5–7 days. This is followed by a maintenance phase of 3–5 grams per day. Alternatively, a consistent daily intake of 3–5 grams without a loading phase can also effectively elevate muscle creatine levels over time.
Creatine monohydrate is the most studied and widely used form, known for its efficacy and cost-effectiveness. It’s advisable to take creatine with a carbohydrate-rich meal to enhance absorption.
