Optimum Nutrition Micronized Creatine Monohydrate
Users on r/Costco and r/Supplements describe ON Creatine as 'too coarse/grainy' compared to competitors, with inconsistent micronization across batches. A troubling r/Supplements thread reports an ammonia smell from a second bottle — 'when I received the second one it had a slight ammonia smell to it' — raising batch quality concerns. Bloating and water retention are commonly reported during the loading phase, though this is typical of all creatine monohydrate products.
Thorne Creatine Monohydrate
Thorne Creatine's most cited complaint is price — Reddit threads frequently ask 'Why is Thorne Creatine so expensive compared to almost every other micronized creatine?' At $36 for 90 servings ($0.40/serving) it costs roughly 70% more than ON ($0.23/serving) for the identical molecule. An r/Supplements user reported 'First Time Taking Creatine Monohydrate (Thorne) Gave Tachycardia — elevated my heart rate to 150-170,' though this is a rare individual reaction rather than a product-specific issue.

The Verdict
Both products contain the identical molecule — 5g micronized creatine monohydrate — so the performance difference is zero. The choice comes down to trust vs value. Thorne's NSF Certified for Sport certification is the gold standard for tested athletes and guarantees batch consistency, justifying its 70% premium for anyone competing in drug-tested sports. ON Creatine delivers the same creatine at $0.23/serving and is the #1 seller on Amazon, making it the smart budget pick for recreational lifters.
