creatine monohydrate superior to other creatine forms
In plain terms: Is plain creatine monohydrate as good as the fancier, pricier forms?
Part of: 🧪 creatine
Yes — monohydrate is the most-studied, nearly fully absorbed, and cheapest form. Head-to-head trials show newer forms like HCl or ethyl ester are no better, and none is proven safer. Save your money.

How the studies fall
What the evidence shows
Creatine monohydrate is the most-studied, ~100% bioavailable, and cheapest form; head-to-head RCTs find alternative forms (HCl, ethyl ester) no more effective, and none has been shown safer or better. 'Superior' = nothing beats it, on far more evidence.

Disagree, or know a study we missed?
We grade by evidence, not opinions. The way to weigh in is to point us to a study we haven't cited (check the evidence table above first), or to flag a problem with one we have. Every submission is reviewed; if it holds up, the grade updates and shows in Science Changes Its Mind.
Opens a short form. You'll sign in with Google so submissions are tied to a real account — we don't display your identity, and we only accept a link we can verify (PubMed, DOI, ClinicalTrials.gov).
