Creatine

Creatine is an organic compound derived from amino acids (arginine, glycine, and methionine) and is naturally produced in the liver, kidneys, and pancreas. Approximately 95% of the body's creatine stores are found in skeletal muscle, with smaller amounts in the brain and testes. Its primary function is to facilitate the recycling of adenosine triphosphate (ATP), the cellular energy currency, particularly during rapid energy demands. When muscles perform high-intensity, short-duration work (like lifting weights or sprinting), ATP is quickly depleted. Creatine phosphate donates a phosphate group to adenosine diphosphate (ADP) to rapidly reform ATP, allowing for sustained bursts of energy. This mechanism helps to improve strength, power output, and overall exercise performance, while also supporting muscle growth and recovery. Beyond its well-known athletic benefits, creatine has also been researched for its potential neuroprotective effects, supporting cognitive function, and aiding in certain neurological conditions. It is one of the most extensively studied and effective supplements for enhancing exercise performance and muscle mass.
