“in the USA in a GMP-certified”
Evidence →“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.

◐Partly confirmed2
“studied to support less shedding and a healthy hair follicle”
Evidence →Published research exists for ingredients in this formula. Whether this product’s doses match those studies could not be confirmed.
Ingredient research can support context, but it is not a trial of this exact product.
△Claimed without support found1
“MyBiotin ProClinical Growth+ - Clinically Studied for Thicker, Fuller Hair - Lustriva (40x Bioavailable Biotin) + Serevelle Saw Palmetto - Hair…”
Evidence →We found no named, citable study of this product or formula. The claim may rest on ingredient research rather than a trial of this product.
?Couldn’t verify independently1
“in the USA in a GMP-certified”
Evidence →“Made in USA” can describe only final bottling. Ingredient-sourcing records were not located for this product.
We looked and found no public proof. That does not count against the product.

Every ingredient shows its real amount — nothing is hidden in a proprietary blend.
Evidence and sources

Research behind the findings
Dose and research context
We could not match an amount on this product to a studied range for the same ingredient, so these links are ingredient background rather than a measurement of this product.
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 10 mg of magnesium per serving. Studies we found used 200 mg–420 mg a day, so this sits below that range.
0studied 200 mg–420 mg
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
