Creatine

Creatine Monohydrate is one of the most well-researched sports supplements available, trusted by athletes and gym-goers for over 30 years. It supports strength, power, and lean muscle gains by aiding in muscle protein synthesis after workouts. And Onnit’s creatine has been tested and approved by Men’s Health as a “Best Creatine Supplement of 2025.”
By helping regenerate ATP—the body’s primary energy source—creatine promotes performance in short-burst, high-intensity activities like lifting, sprinting, and martial arts. It also supports brain’s normal energy demands, offering cognitive benefits beyond the gym.†︎
