creatine monohydrate superior to other creatine forms

In plain terms: Is plain creatine monohydrate as good as the fancier, pricier forms?

consensus score 0.66

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 far up the ladder this claim has climbed. A high consensus on a low rung means "consistent so far," not "proven in people."

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.

RCT mixed moderate RCT: HCl/ethyl-ester dosing raised brain creatine and outcomes but did not demonstrate superiority to monohydrate as the reference form.

RCT supports moderate RCT: creatine-HCl and monohydrate produced similar strength and body-composition gains — HCl showed no advantage over monohydrate.

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.
