What is creatine?

An introduction to creatine — what it is, where it comes from, and how Creatine Science reviews the research.

Creatine is a nitrogen-containing organic compound that the human body produces naturally in the liver, kidneys, and pancreas, and that also occurs in foods such as meat and fish. In supplement form it is most often sold as creatine monohydrate. Creatine Science is an independent project that reads the published scientific literature on creatine and summarizes what individual studies report, with links to their primary sources.
