Why does monohydrate appear in so many studies?
Monohydrate is the form used in much of the established exercise and safety research described by the position stand. That history makes its results easier to interpret. It does not mean every product containing it has been independently tested, or that every person needs a creatine supplement. [1]
Is buffered creatine better?
A small 28-day comparison in resistance-trained men found no advantage for buffered creatine on the measured strength, body-composition and muscle-creatine outcomes. The trial was short and industry funded. Its findings challenge a superiority claim for that protocol, rather than answering every possible question about every alternative form. [2]
Can results from one form be applied to another?
Not automatically. The small menopause cognition trial used hydrochloride and related formulations, while much of the broader evidence concerns monohydrate. The form, amount and study conditions are part of the result. A finding with one formulation should not be presented as proof for every creatine product. [3] [1]

What are the limits of this evidence?
Each card separates the finding from the limits. The participants, formulation and duration are part of the answer.
Kreider et al., 2017
Daily lower doses can raise muscle creatine stores gradually; a loading phase is optional.
- Who
- Mixed populations in the reviewed research
- Dose
- Includes 3 to 5 g/day maintenance protocols
- Duration
- Varied across studies
- Limits
- A position statement synthesising varied research. It is not an individual dosing prescription. Several authors disclose industry relationships.
Jagim et al., 2012
Buffered creatine did not show better muscle creatine, body composition or performance outcomes than monohydrate.
- Who
- 36 resistance-trained young men completed the trial
- Dose
- Buffered: 1.5 g/day or loading/maintenance; monohydrate: 20 g/day then 5 g/day
- Duration
- 28 days
- Limits
- Small, short male-only trial. Results for this buffered formulation do not settle every alternative form. Industry funding disclosed.
