While protein is necessary for muscle growth, creatine monohydrate is considered the most important gym supplement. This is because creatine has proven ergogenic effects, meaning it is a suitable sports performance enhancer. In fact, 3-5 grams of creatine can increase muscle strength, power output, speed, and lean muscle mass. Aside from its guaranteed efficacy, it’s also proven safe and is recommended for short bursts of high-intensity physical activity.
