Micronized Creatine Powder

- ON lists its creatine as Informed Choice certified for banned-substance screening
- Large tubs cost about $0.20 per serving
- Neutral taste that disappears into shakes, per most buyer reviews

Our verdicts
Creatine Monohydrate Powder
Nutricost is the value leader among mainstream creatine brands: the same 5 g of monohydrate as the big names for about $0.22 a serving, with a scoop included and strong buyer satisfaction. It lacks a named third-party certification, so competitive athletes should look elsewhere, but for everyday lifters it is hard to beat on cost.

Micronized Creatine Powder
A dependable, no-frills creatine from the category's best-known brand, with Informed Choice certification and a clean single-ingredient label. It is not the cheapest per gram and it does not fully dissolve in plain water, but it delivers exactly what the research supports at a fair price.
