creatine

Creatine is a naturally occurring compound found in small amounts in certain foods such as meat and fish. It is also available as a dietary supplement. Creatine is stored in the muscles in the form of phosphocreatine and is used as an energy source during high-intensity, short-duration activities such as weightlifting and sprinting. It is also commonly used as a dietary supplement by athletes looking to increase their strength and athletic performance. When taken as a dietary supplement, creatine is typically taken in a loading phase (20 grams per day for 5-7 days) followed by a maintenance phase (3 grams per day).
