What did the gummy testing report find?

The report found substantial discrepancies between measured creatine and some label claims in six selected US products. It is a product-testing report, not a clinical trial. Sampling, batch identity and the testing date limit what it can establish about another purchase, a changed recipe or the wider market. [1]

02

Does a serving size prove the amount of creatine?

A label describes the amount a manufacturer claims to supply. It does not independently verify the creatine in a particular batch. The selected-product report shows why those are separate questions. A useful test should identify the finished product and batch, method, laboratory and date clearly enough to assess. [1]

03

Does creatine research prove a gummy works the same way?

Research on creatine monohydrate cannot verify the content or stability of every finished gummy. Formulation conditions can matter, and the reviewed chemistry distinguishes dry powder from creatine in solution. Evidence about an ingredient needs to be connected to evidence about the actual product before making an equivalent performance claim. [2] [3]

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.

Review2021

Antonio et al., 2021

The reviewed studies do not support creatine causing fat gain; water changes and dosing need separate consideration.

Who
Mixed populations across the reviewed research
Dose
Varied; includes daily and loading protocols
Duration
Varied across studies
Limits
A narrative review, not one trial. Populations and methods differ. Several authors report supplement-industry relationships.
