Creatine monohydrate is one of the most studied and effective supplements for improving strength, muscle mass, and athletic performance. Here’s what it does:
 
• Increases energy production: It helps your body produce more ATP (adenosine triphosphate), which is the primary energy currency for your muscles during high-intensity activities like sprinting or weightlifting.
• Enhances strength and power: Supplementing with creatine often leads to noticeable improvements in strength, power output, and performance in short-duration, high-intensity exercises.
• Promotes muscle growth: Over time, creatine can help increase muscle mass both by improving training performance and by drawing more water into muscle cells (cell volumization).
• Speeds up recovery: Some research shows it can help reduce muscle damage and inflammation, leading to faster recovery between intense workouts.
• Supports brain health: Emerging research suggests creatine might also benefit cognitive function, especially under stress or sleep deprivation.
 
It’s generally considered safe when taken in recommended doses (typically 3–5 grams per day after an initial loading phase, if you choose to do one).
