Creatine

Thorne Creatine is a single-ingredient micronized creatine monohydrate powder: one scoop delivers 5 g, the daily amount used in most creatine research, and there are no sweeteners, flavors or fillers in the unflavored tub. Creatine monohydrate is the best-studied sports supplement for increasing muscle creatine stores, which supports performance in short, repeated high-intensity efforts and gains in lean mass alongside resistance training.

What separates it from mainstream tubs is verification. The product is listed in NSF's Certified for Sport database, which, as Thorne explains it, means it is tested for label-claim accuracy and for nearly 300 substances banned by major athletic organizations. Thorne also says it tests ingredients and finished products for identity, purity and potency, including heavy metals, pesticides and microbes. That combination makes it a common pick for drug-tested athletes and for anyone who values independent confirmation over marketing.

Buyer feedback is strong on the basics. buyers most often praise its quality, how easily it dissolves and its lack of taste, though a minority find it slightly grainy and some mention stomach upset. Creator reviews echo the fine, powdered-sugar texture that leaves water a little cloudy rather than gritty.

The trade-off is price. At $44 for 90 servings on Thorne's site, it costs roughly $0.49 per serving, well above budget creatine for the same molecule. Thorne also offers Pineapple Orange and Strawberry versions and a 180-serving tub.
