Creatine Side Effects: What You Should Know Before Taking Creatine
Creatine side effects are one of the most common concerns for people who are considering using creatine supplements. Creatine is one of the most researched sports supplements in the world and is widely used by athletes, bodybuilders, and fitness enthusiasts to improve strength and muscle performance.
Although creatine is generally considered safe for healthy adults, it is important to understand potential creatine side effects before starting supplementation. Knowing how creatine works and how to use it correctly can help you make an informed decision.
What Is Creatine?
Creatine is a natural compound that is stored in your muscles and helps produce energy during short bursts of intense exercise. The body naturally produces creatine in the liver, kidneys, and pancreas, and it can also be obtained from foods such as red meat and fish.
However, the amount of creatine from food is relatively small. For this reason, many athletes choose creatine supplements to increase the creatine stored in their muscles and improve physical performance.
Creatine monohydrate is the most common and widely studied form of creatine used in sports nutrition.

Common Creatine Side Effects
When used correctly, creatine is generally well tolerated by most people. However, some individuals may experience mild creatine side effects.

- Weight gain – usually caused by increased water storage in muscles
These effects are typically mild and often disappear when creatine is taken in recommended doses.
