Thorne Creatine Review: A Simple NSF-Certified 5 g Formula

August 9, 2026

Key Score: 9.0/10

Thorne Creatine is a straightforward pick for athletes who want a simple 5 g creatine-monohydrate serving with NSF Certified for Sport verification. Its main drawback is price: it is a premium powder when compared with basic unflavored monohydrate.

What is in it?

The unflavored version provides 5 g creatine monohydrate per serving. Thorne states the product is NSF Certified for Sport; NSF’s own certification listing includes Thorne Creatine.

Why it scores well

  • Full 5 g monohydrate serving.
  • NSF Certified for Sport, a useful safeguard for tested athletes.
  • No need for a proprietary blend or stimulant add-ons.

What to consider

Certification does not make the product medically necessary, and this is not the best value for everyone. Compare cost per 5 g serving before buying.

Bottom line

A strong premium option for someone who values sport certification and a plain 5 g dose. Product details · NSF listing.
