Creatine: What the Research Actually Says

Creatine monohydrate has been the subject of thousands of peer-reviewed studies over the past three decades. It is one of the few supplements with consistently replicated findings across independent research groups.

What creatine does

Creatine is a naturally occurring compound synthesized in the liver, kidneys, and pancreas from amino acids glycine, arginine, and methionine. It is also found in animal-based foods. The body stores creatine primarily in skeletal muscle as phosphocreatine.

During high-intensity, short-duration exercise (sprints, heavy lifts, explosive movements), phosphocreatine donates a phosphate group to regenerate ATP — the cell's primary energy currency. Supplementing with creatine monohydrate increases total phosphocreatine stores by roughly 20–40%, which supports a greater capacity to sustain high-intensity output before fatigue sets in.

Documented effects

Research consistently shows creatine supplementation may support:

Standard dosing

A loading phase (20g/day split into 4 doses for 5–7 days) followed by maintenance (3–5g/day) saturates muscle stores faster. However, simply starting with 3–5g/day achieves the same saturation over 3–4 weeks without loading side effects.

Safety

Decades of research have found creatine monohydrate to be well tolerated in healthy adults at standard doses. The reported concern about kidney stress has not been supported by research in healthy individuals.
