Creatine supplements remain one of the most effective and extensively studied ways to enhance strength and exercise performance. Unlike most supplements, creatine has robust evidence showing it helps muscles produce energy quickly, improving high-intensity exercise capacity and supporting muscle growth.
When consumed, creatine converts to creatine phosphate in the muscles, which aids in producing adenosine triphosphate (ATP), the primary energy source for short, explosive movements. For many people, supplementation offers a convenient alternative to consuming large amounts of meat, which naturally contains creatine (a two-pound steak contains roughly 5 grams).
How We Selected These Supplements
In collaboration with Jose Antonio, PhD, C.S.C.S., a professor of Exercise and Sport Science at Nova Southeastern University, we evaluated more than two dozen creatine products. Our criteria included third-party testing, certifications from NSF or Informed Sport, ingredient transparency, and price per standard 5-gram serving—the amount shown in research to be effective for most adults.
Key considerations for consumers:
Dosage: 3–5 grams of creatine monohydrate daily is generally sufficient.
Form: Micronized creatine is recommended for better absorption and minimal stomach discomfort.
Ingredients: Single-ingredient creatine is preferred; avoid unnecessary additives.
Certification: NSF or Informed Sport certifications ensure purity and safety.
