Creatine monohydrate

One of the most studied supplements in sports nutrition. Most products contain the same single ingredient.

What to look for

• Creatine monohydrate listed as the only ingredient
• A third-party testing seal such as NSF Certified for Sport or Informed Sport
• Price per 5 g serving, not price per tub

Supplements aren't FDA-approved before they're sold, and quality varies. Talk to a doctor before starting anything new.
