Creatine is most commonly used for improving exercise performance and increasing muscle mass in athletes and older adults. There is some science supporting the use of creatine in improving the athletic performance of young, healthy people during brief high-intensity activities such as sprinting. Because of this, creatine is often used as a dietary supplement to improve muscle strength and athletic performance.
Creatine can cause stomach pain, nausea, diarrhea, and muscle cramping.
Creatine causes muscles to draw water from the rest of your body. Be sure to drink extra water to make up for this. Also, if you are taking creatine, don’t exercise in the heat. It might cause you to become dehydrated.
