What is a Creatine (C₄H₉N₃O₂)?

Creatine (C₄H₉N₃O₂) is an organic compound that plays a key role in energy production within the human body, particularly in muscles and the brain. It is synthesized from amino acids in the body, but can also be obtained from meat and fish. Creatine is stored in muscle cells, where it aids in quickly replenishing ATP, the energy currency of cells, during short bursts of intense activity.

Creatine supplementation is commonly used by athletes to enhance performance in high-intensity, short-duration activities like weightlifting and sprinting. It can increase muscle water content, leading to temporary weight gain, which is due to water retention, not fat accumulation. Creatine is generally considered safe when used correctly, but high doses over extended periods may lead to digestive discomfort or kidney stress.
