What is creatine monohydrate?

Creatine monohydrate is a form of creatine, a compound found in the body that helps regenerate ATP for short, high-intensity efforts. It is commonly used to support training performance and muscle gains.

What are the main benefits of creatine monohydrate?

It can improve strength and power during repeated high-intensity exercise and support greater muscle mass gains when paired with resistance training. Some evidence also suggests potential cognitive benefits in certain situations.

How much creatine monohydrate should I take?

A common maintenance dose is 3–5 g per day. Some people use a short loading phase, but it is not required for results.

Is creatine monohydrate safe?

For most healthy adults, creatine monohydrate is generally well tolerated when used as directed. People with kidney disease or those who are pregnant or breastfeeding should consult a clinician before use.

What are common side effects of creatine monohydrate?

Some people experience water retention, mild weight gain, or gastrointestinal discomfort, especially with larger doses. Taking smaller doses and mixing well with fluid can help reduce stomach upset.
