Go to Dedicated Guide →The NIH Office of Dietary Supplements summarizes evidence that creatine can improve strength, power, and repeated maximal efforts by replenishing intramuscular phosphocreatine (PCr) stores. Its value for predominantly endurance activities is less clear. Individual responses vary.
Studies frequently use a loading phase of approximately 20 g per day (split into 4 doses of 5 g) for 5–7 days followed by a maintenance phase of 3–5 g per day, or a steady approach of approximately 3–5 g per day without loading. These are research protocols, not personalized medical prescriptions.
Check the Supplement Facts panel for 100% creatine monohydrate and the declared dose per serving (typically 5 g). Compare total servings per container and merchant price to calculate true cost per gram. Avoid proprietary blends that conceal the exact creatine amount behind added carbohydrates or electrolytes.
If a product displays a certification seal such as NSF Certified for Sport or Informed Choice, confirm the exact product name, package size, flavor, and lot number in the certifying body’s official directory. A manufacturer claim or testing on a separate product line does not verify the specific bottle purchased.
Intracellular water retention is expected during creatine saturation and should not be mistaken for body fat gain. Mild gastrointestinal discomfort can occasionally occur, particularly with large single doses taken without adequate water.
Individuals with pre-existing renal conditions or those taking nephrotoxic medications should consult a qualified physician prior to supplementation. Our interactive calculator illustrates common saturation timelines but cannot assess personal clinical safety.
