Which compound is commonly taken as a supplement to enhance muscle strength and power? Creatine is the standard answer.
Creatine is a naturally occurring compound made from amino acids and stored mainly in skeletal muscle as phosphocreatine. During brief, intense efforts—such as sprinting, jumping, or heavy lifting—it helps rapidly regenerate ATP, the cell’s immediately usable energy source. Supplementing with creatine can increase the muscle’s available phosphocreatine and improve repeated high-effort performance.
Creatine monohydrate is the most studied form. A commonly used approach is 3–5 grams daily; some athletes begin with a loading phase of about 20 grams daily for up to a week, divided into smaller doses. Benefits are most relevant to short, intense, intermittent exercise, not long-duration endurance events.
A common mix-up is treating creatine as a steroid or as a protein. It is neither: it is a non-hormonal performance supplement, and its early weight increase is often water stored in muscle rather than newly built muscle tissue. Healthy adults generally tolerate standard use, but people with medical conditions should consult a clinician.
