WASHINGTON - Creatine might sound like something reserved for bodybuilders or supplement junkies, but it's actually one of the most widely studied (and misunderstood) tools in the fitness and wellness ...

"Creatine is converted into creatine phosphate, ... So, for example, an individual doing multiple sets of heavy weightlifting "is using ATP for energy," explains Veldhuizen.

Your bloodstream then shuttles the creatine to your muscles, which convert it into creatine phosphate, a potent form of cellular energy, says Cleveland Clinic dietitian Kate Patton, R.D., C.S.C.S.

The majority of creatine is stored in the skeletal muscles in a form known as phosphocreatine, or creatine phosphate. A small amount, less than 5%, is found in the tissues of the brain and testes.

Creatine is a popular supplement among athletes and bodybuilders, as it often helps increase muscle mass, strength, and endurance by increasing the amount of creatine phosphate stored in the muscles.

Supplement companies direct creatine loading when starting. Experts breakdown what creating loading is, whether or not you should do it, and side effects.

Creatine phosphate helps you produce more adenosine triphosphate (ATP), a neurotransmitter that is your body’s primary source of energy. Weight training and exercise require a lot of energy.

Creatine phosphate is an ATP reserve in muscle that can be readily converted to sustain activity for ~3-5 min. The amount of creatine phosphate available in skeletal muscle is approximately four ...
