The checks, one by one

The public sources did not settle the marketing promises on this label.

Partly confirmed2

“Biotin Gummies for Hair Growth Support - for Women & Men - Berry, 60 Gummy SUGAR”

Published research exists for ingredients in this formula — see Related research below. Whether this product’s doses match those studies could not be confirmed.

Evidence →
“NON-GMO EFFECTIVE GLUTEN-FREE GMO-FREE GMP COMPLIANT MANUFACTURING PRACTICE ISO”

“GMP-certified” describes factory processes, not what is in the bottle. The claim does not name a certifier or public register that a shopper can check.

Evidence →

Ingredient research can support context, but it is not a trial of this exact product.

Research behind the findings

Dose and research context

The label amount is shown beside the ranges used in the linked ingredient studies.

Background reading

What the research says about these amounts

Not a score. Studies disagree with each other and change over time, so this sits beside the evidence rather than counting toward it — it is here so you can read the sources yourself.

The panel lists 150 mg of collagen peptides per serving. Studies we found used 2.5 g–15 g a day, so this sits below that range.

0studied 2.5 g–15 g

Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.

The panel lists 3 mg of zinc per serving. Studies we found used 8 mg–40 mg a day, so this sits below that range.
