Thorne's creatine is a single-ingredient, unflavored, NSF Certified for Sport micronized creatine monohydrate with zero carbs, sugars, or fillers, making it a clean, contaminant-tested way to add a well-studied performance supplement without disrupting ketosis.
Optimum Nutrition's Micronized Creatine Powder uses Creapure creatine monohydrate, is unflavored with zero carbs and zero calories, and is one of Amazon's best-selling creatine powders overall. It delivers the same 5g dose as Thorne's pick at a noticeably lower cost per serving, though it carries 'banned substance tested' claims rather than full NSF Certified for Sport certification.
Like Thorne's pick, Momentous Creatine is NSF Certified for Sport, but it goes further with additional third-party testing for PFAS, heavy metals, and microplastics beyond what the certification requires, and is manufactured with reverse-osmosis water washing in an ISO 9001/14001-certified pharmaceutical facility — a step-up option for athletes who want the strictest available purity standards.
