ThorneCreatine

Overview

Thorne's Creatine is plain, micronized creatine monohydrate: one 5 g scoop, 90 servings per tub and no flavors or fillers. Its standout is certification. It is NSF Certified for Sport, which NSF's own certified-products list confirms, meaning it is tested for compliance with label claims and screened for nearly 300 substances banned by major athletic organizations. Thorne says it is trusted by more than 100 professional sports teams, and the powder is free of gluten, dairy and soy. A 180-serving size is also sold, and dozens of other Thorne products appear on NSF's certified list as well.

What reviewers say

Long-term users are enthusiastic: the Abbotts At Home channel posted a six-month review saying they are big fans, and Athletic Insight's review looks at mixability, purity and price alongside the NSF seal. Newer reviews, including Cole Schwartz's 2026 video, focus on whether the premium price is justified. The consensus is that performance matches any quality creatine monohydrate; what you pay extra for is certification and brand trust.

Who it's for

Drug-tested athletes, military personnel and first responders subject to testing, and anyone who wants maximum assurance about what is in their creatine. It is also a natural fit for shoppers who already trust Thorne's other supplements and want a single brand with consistent third-party certification across their daily stack.

Bottom line

At about $0.49 per serving it is not a bargain, but it is one of the most trusted creatines available and the easiest choice when certification matters more than cost. Check both Amazon and Thorne's own store, since prices on its official TikTok Shop listing ran higher at research time.
