Creatine does not hurt the stomach, which may be related to the effect of eating oranges and creatine. People should rest their stomachs at night, the fruits they eat are not easy to digest, and creatine is not easy to absorb, which causes gastric mucosal irritation and pain. It is recommended not to eat fruit at night. By the way, creatine should be used with simple carbohydrates to increase absorption efficiency.

I hope my suggestion will help you!
