Optimum Nutrition Micronized Creatine

by Optimum Nutrition (Glanbia)

If supplements were graded purely on evidence-per-dollar, creatine monohydrate would top the entire industry - hundreds of studies support modest strength and performance benefits from a boring 3-5g daily. ON's micronized version mixes decently, tests clean, and costs pennies a day. The rare supplement that is exactly what it claims.

Creatine monohydrate is the most-researched performance supplement in existenceSingle-ingredient label: no proprietary blends, no fairy dustMicronized powder mixes better than bargain-bin creatine
