Optimum Nutrition Micronized Creatine Powder review

Optimum Nutrition's Micronized Creatine Powder is the easy default for lifters who already buy ON protein. The US product page lists 5g of creatine monohydrate per serving and prices the 60-serving tub at $20.49, which it shows as $0.34 per serving. Subscribing takes 20% off and adds free delivery, and the page says subscriptions can be paused, skipped or canceled without fees. The powder is micronized and sold unflavored or in fruit flavors, and the page pitches it as stackable with Gold Standard 100% Whey. Where it falls behind the top pick is documentation: the US page we checked names no outside certification, while Thorne, Momentous and Bare Performance Nutrition all carry NSF Certified for Sport. It is also roughly twice the cost per dose of Naked Nutrition's large tub. For a lifter who wants a known name, a small first tub and a low entry price, it is still one of the safest picks here.
