A note on third-party testing
NSF Certified for Sport (Thorne) tests every batch against banned substances; Nutricost states ISO-accredited lab testing without an every-batch sport mark. For tested athletes the gap matters; for general users, both provide the same studied dose. Verify certifications on the current packaging.
Is Thorne or Nutricost creatine better?
The creatine is identical: 5 g micronized monohydrate. Thorne (9.3/10) adds every-batch NSF Certified for Sport testing; Nutricost (8.4/10) offers the same dose at a budget price with ISO-lab testing. Choose Thorne for certification, Nutricost for value.
Do they use the same creatine?
Yes — both are micronized creatine monohydrate at 5 g per serving, single ingredient. The difference is certification and price, not the active.
Is Thorne worth the premium?
For tested athletes, the every-batch NSF Certified for Sport testing can justify the price. For general gym users, Nutricost delivers the same studied dose for considerably less.
Which is better for beginners?
Either works. Start at 3-5 g daily and judge after about a month. If budget matters, Nutricost is the sensible pick; if you compete under testing, Thorne is safer.
