Creatine is stored in muscles as phosphocreatine, which helps regenerate ATP (adenosine triphosphate) — the main energy molecule used during short bursts of high-intensity activity. Result: • Improved strength • Better high-intensity exercise performance • Faster recovery between sets 2. Proven Benefits Exercise & Muscle • Increases muscle strength and power • Improves high-intensity exercise performance • Helps increase lean muscle mass • Enhances recovery after workouts Brain & Cognitive Effects • May improve short-term memory • May help with mental fatigue • Being studied for neurodegenerative diseases Medical/Clinical Uses Being Studied • Sarcopenia (muscle loss with aging) • Neurological disorders • Muscle wasting diseases • Heart failure rehabilitation 3. Typical Dosage Loading method • 20 g/day (divided into 4 doses) for 5–7 days • Then 3–5 g/day maintenance No-loading method • 3–5 g/day continuously • Muscle saturation reached in ~3–4 weeks For most people: 3–5 g daily is sufficient. 4. Safety Profile Creatine monohydrate is considered very safe in healthy individuals when taken in recommended doses. Possible minor side effects • Mild water retention • Bloating (occasionally) • GI discomfort if high doses are taken at once Kidney safety • Studies show no kidney damage in healthy individuals. • However, caution is advised in: • Chronic kidney disease • Patients with elevated baseline creatinine 5. Who Should Avoid or Use With Caution • Patients with chronic kidney disease • Severe liver disease • Pregnancy or breastfeeding (insufficient safety data) • Individuals taking nephrotoxic drugs 6. Creatine monohydrate vs Other Forms Creatine monohydrate is the gold standard. Other marketed forms include: • Creatine HCL • Creatine ethyl ester • Buffered creatine Most studies show no advantage over monohydrate, while monohydrate is cheaper and better studied. 7. Practical Advice for Use • Dose: 3–5 g daily • Take with water or carbohydrate-containing meal • Maintain adequate hydration • No strict cycling required
