Creatine monohydrate is one of the most studied sports supplements. It can support repeated high-intensity effort and strength training, but it is optional.
What creatine does
Creatine helps increase the availability of phosphocreatine in muscle, which supports rapid energy production during short, intense efforts. Over time, better training performance can contribute to strength and muscle gains.
It is not a stimulant and does not create an immediate feeling like caffeine.
Keep the method simple
A common maintenance approach is three to five grams of creatine monohydrate daily. Loading can saturate stores faster but is not required. Consistent daily use works over time.
Timing matters less than regular intake for most people.
Expect possible scale change
Creatine can increase water stored inside muscle, so body weight may rise. That change is not body fat and may occur before visible performance changes.
People focused on scale weight should know this before starting.
Use appropriate caution
Healthy adults generally tolerate creatine well in research, but anyone with kidney disease, pregnancy, medication concerns or relevant medical conditions should speak with a clinician first.
