Some people may experience potential side effects, which can include:
-
Gastrointestinal issues: Some individuals may experience stomach cramps, nausea, diarrhea, or bloating when taking creatine supplements. These effects are generally mild and can be minimized by staying adequately hydrated.
-
Weight gain: Creatine supplementation can lead to an increase in water retention within muscle cells, which may result in a slight increase in body weight. This water weight gain is temporary and not indicative of actual muscle growth.
-
Muscle cramps: In some cases, people using creatine may experience muscle cramps, although this is relatively rare.
