Introduction
Creatine is a compound found in the body and in some foods. It is also sold as a dietary supplement, most often as creatine monohydrate. SuppCheckr explains creatine in educational guides and compares supplement labels — we do not provide medical advice.
What creatine is
According to NIH Office of Dietary Supplements consumer materials, the body produces some creatine and additional creatine can come from animal-based foods. Supplemental creatine is commonly used in exercise and sport nutrition contexts. Research has examined creatine for short, high-intensity efforts such as weight training or sprinting; it is not mainly studied for long endurance events.
How creatine is commonly used in supplements
Most creatine supplements on the market use creatine monohydrate. NIH health-professional materials note that creatine monohydrate is the most widely used and studied supplemental form. Other forms exist; see our guide on creatine monohydrate vs. HCL for a high-level comparison without product recommendations.
What creatine supplements are not
Dietary supplements are not drugs and are not FDA-approved to diagnose or mitigate disease. According to FDA overview materials, supplement manufacturers may not make disease-treatment claims. SuppCheckr does not describe creatine as a medical treatment.
