Ingredient Quality
Optimum Nutrition is one of the most trusted names in sports nutrition. Its micronised creatine is good quality pure monohydrate — though notably it is not Creapure-branded.
Value Analysis
This is the weak point. At £16.99 you're paying a premium for generic monohydrate. Reflex offers actual Creapure for less, and Warrior offers equivalent generic monohydrate for less too. You're paying for the ON brand.
Effectiveness
The 5g serving matches research protocols and the micronised powder mixes well. Effectiveness is not in question — only value.
Who Is This Best For?
People who specifically trust the Optimum Nutrition brand and don't mind paying for it. On pure value, there are better options.

Optimum Nutrition Micronised Creatine Powder FAQ
Is Optimum Nutrition creatine Creapure?
No — Optimum Nutrition uses its own micronised creatine monohydrate, not Creapure. It's good quality, but you can get actual Creapure (e.g. Reflex) for a similar or lower price.
