What are the benefits of creatine?

　　In addition to enhancing athletic performance, creatine may also exert beneficial effects on the brain, heart, and neuromuscular disorders. Specifically, creatine offers the following ten key benefits:

　　→Helps muscle cells produce more energy

　　Creatine supplements can increase the storage of phosphocreatine in muscles, and phosphocreatine facilitates the synthesis of adenosine triphosphate (ATP).

　　During exercise, ATP molecules are broken down to release energy, but the rate at which ATP is regenerated limits your ability to sustain high-intensity activity.

　　Creatine supplementation can increase phosphocreatine stores, enabling you to produce more ATP during high-intensity exercise and thereby enhancing athletic performance.

　　Creatine supplementation can increase the synthesis of proteins that form new muscle fibers and elevate levels of insulin-like growth factor 1 (IGF‑1), a hormone that promotes muscle growth.

　　In addition, creatine supplementation can increase muscle water content—known as cell volumization—thereby rapidly enhancing muscle size.

　　In addition, some studies have shown that creatine can lower levels of myostatin; as its name suggests, this molecule inhibits muscle growth, and reducing myostatin levels may help accelerate muscle gain.

　　→Enhance high-intensity athletic performance

　　Because creatine has a direct effect on ATP production, it can significantly enhance performance in high-intensity exercise.

　　Creatine can also enhance numerous factors, including strength, sprint performance, muscular endurance, fatigue resistance, muscle mass, recovery, and cognitive performance. A review study found that creatine can improve high-intensity exercise performance by as much as 15%.

　　Additionally, some fitness supplements are effective only for elite athletes, whereas creatine offers more universal performance benefits across the board. Supplementing with creatine can benefit individuals at all fitness levels.

　　→Accelerate muscle growth

　　Creatine is the most effective muscle-building supplement; taking it for just 5–7 days can significantly increase lean body mass and muscle size.

　　This initial increase is primarily due to a rise in muscle water content, and long-term creatine supplementation can promote the growth of muscle fibers.

　　In a 6-week training program study, participants who supplemented with creatine experienced a significant increase in muscle mass compared to the control group, gaining an average of 4.4 pounds (2 kilograms) more muscle per person.

　　→Helps improve Parkinson’s disease

　　Parkinson’s disease is characterized by reduced levels of dopamine, an important neurotransmitter in the brain.

　　A sharp decline in dopamine levels can lead to the death of brain cells and a range of severe symptoms, including tremors, loss of muscle function, and speech impairments.

　　In animal studies, creatine has been associated with beneficial effects in mice with Parkinson’s disease, as it can reduce the decline in dopamine levels by up to 90%. However, the effects of creatine on human Parkinson’s disease remain to be further investigated.

　　Creatine may alleviate some symptoms of Parkinson’s disease by enhancing muscle strength and function; to address the loss of muscle function and strength, patients with Parkinson’s disease often engage in weight‑training exercises.

　　In a study involving individuals with this condition, combining creatine supplementation with resistance training resulted in greater improvements in strength and functional mobility compared to training alone.

　　→Combating other neurological disorders

　　A key factor in several neurological disorders is the reduction of phosphocreatine in the brain.

　　Creatine can increase creatine phosphate levels, so it may help reduce or slow disease progression.

　　This restorative function of creatine phosphate helps maintain patients’ daily functional capacity, and animal studies have shown that creatine supplementation may also be effective in treating other conditions, including:

　　Alzheimer’s disease;

　　Ischemic stroke;

　　Epilepsy;

　　Brain or spinal cord injury;

　　Creatine has also been shown to confer benefits in amyotrophic lateral sclerosis, a disease that affects motor neurons, which are essential for movement.

　　Although further research in humans is still needed, researchers believe that, when used in combination with conventional medications, creatine supplementation can enhance the nervous system’s resilience to disease, alleviate symptoms and slow the progression of neurological disorders, and improve patients’ life expectancy.

　　→Lower blood glucose levels and combat diabetes

　　Research indicates that creatine supplementation can lower blood glucose levels by enhancing the function of glucose transporter type 4 (GLUT‑4), a molecule that facilitates the uptake of glucose into muscle tissue.

　　A 12-week study examined how creatine affects postprandial blood glucose levels. Subjects who combined creatine supplementation with exercise exhibited a faster return to baseline blood glucose and improved glycemic control compared with the exercise-only control group.

　　Postprandial blood glucose is an important indicator of diabetes risk; the faster the body clears sugar from the bloodstream, the better. Creatine may help lower postprandial blood glucose levels, but further research is needed to determine its long-term effects on glycemic control.

　　→Improve brain function

　　Creatine plays an important role in brain health and function, as the brain requires substantial amounts of ATP when performing demanding tasks.

　　Creatine can increase phosphocreatine stores in the brain, helping it produce more ATP, and it may also provide the brain with additional energy by boosting dopamine levels and mitochondrial function.

　　Since meat is the primary source of creatine, vegetarians typically have lower creatine levels. A study examining creatine supplementation in vegetarians found that some participants experienced a 20–50% improvement in memory and cognitive test scores.

　　For older adults, a two-week creatine supplementation can significantly enhance memory and recall.

　　In older adults, creatine can enhance brain function, help prevent neurodegenerative diseases, and reduce age-related loss of muscle mass and strength.

　　→Can help reduce feelings of fatigue

　　Creatine can alleviate symptoms of fatigue and tiredness by providing your brain with extra energy and boosting dopamine levels.

　　In a 6-month study involving patients with traumatic brain injury, those who supplemented with creatine experienced a 50% reduction in dizziness; furthermore, only 10% of the creatine-supplemented participants reported fatigue, compared to 80% in the control group.

　　Another study found that, during sleep deprivation, creatine can reduce fatigue and boost energy levels when sleep is insufficient.

　　Creatine can also reduce fatigue in athletes performing cycling tests under high-temperature conditions.

　　→Affordable, safe, and easy to use

　　In addition to its many benefits, creatine is one of the most affordable and safest supplements, often hailed as the best value for money. A wide variety of creatine brands are available online, making it easy to purchase.
