Creatine Dose Calculator

The International Society of Sports Nutrition recommends a maintenance dose of 3 to 5 grams of creatine monohydrate per day for most adults. Some protocols use a loading phase of 20 grams per day split into four doses for 5 to 7 days to saturate muscle stores faster, followed by the 3 to 5 gram maintenance dose. Loading produces no additional long-term benefit over simply taking 3 to 5 grams daily; it just reaches saturation more quickly. Larger individuals may benefit from doses at the higher end of the range.

Creatine monohydrate is one of the most researched supplements in sports nutrition. Studies spanning 5 or more years of continuous use in healthy adults show no adverse effects on kidney or liver function, blood pressure, or other health markers. The common concern that creatine damages kidneys is not supported by clinical evidence in healthy individuals. People with pre-existing kidney disease should consult a physician before supplementing with creatine.

Research does not show a strong time-dependent effect for creatine. Most studies find that consistent daily intake matters more than precise timing. Some evidence suggests taking creatine close to a workout (before or after) may modestly enhance muscle retention compared to mid-day dosing, but the difference is small. Taking it with a meal containing carbohydrates and protein can improve absorption slightly. Consistency matters most.

Creatine draws water into muscle cells (intracellular fluid), which can increase body weight by 1 to 3 pounds in the first week of supplementation, particularly during a loading phase. This is not fat or subcutaneous water retention; it is intramuscular hydration associated with improved performance and cell volume. Some athletes notice fuller-looking muscles. The weight increase is a normal and expected response. Long-term creatine use also supports lean mass gains through improved training capacity.
