Methylguanidoacetic Acid (CREATINE)

FDA-approved active Small molecule Quality 6/100

Methylguanidoacetic Acid, also known as Creatine, is a small molecule drug in the creatine class. It is used to increase muscle strength and endurance, particularly in athletes and individuals with muscle-wasting diseases. The commercial status of Creatine is complex, as it is available both as a patented supplement and as a generic product. Key safety considerations include potential gastrointestinal side effects and interactions with certain medications. As a dietary supplement, Creatine is not regulated by the FDA in the same way as prescription medications.
