Buying Guide: What to Look for in a Creatine Supplement
Purity and Micronization
Optimum Nutrition uses 5 grams of micronized creatine monohydrate per serving in its powders. Micronization means the particles are smaller, which improves mixing and absorption.

This third-party validation gives you confidence in what you are putting into your body.
Form: Powder vs Capsules
Optimum Nutrition provides both unflavored powder and capsule options. The powder delivers 5 grams per scoop, ideal for post-workout shakes or stacking with protein. Capsules offer 2.5 grams per serving (two capsules), perfect for those who dislike mixing.
