The Claim

Creatine monohydrate supplementation at a dosage of 5 g/day for 5–7 days followed by 3–5 g/day maintenance increases intramuscular creatine and phosphocreatine stores by 20–40% in healthy individuals, which enhances high-intensity exercise capacity and promotes greater gains in strength and lean muscle mass during resistance training.

In plain English

Taking creatine powder every day for a week, then a smaller dose after that, can help your muscles store more energy, making you stronger and better at intense workouts like weightlifting.
