Does the marketing hold up?

Ingredient amounts are hidden inside “Proprietary Blend”. A blend total may be legal, but it prevents you from knowing whether any individual ingredient reaches a meaningful amount.

“Couldn’t verify” means we looked and found no public proof — not a mark against the product. Most supplement claims cannot be independently verified by anyone, so grey is the normal state of this industry.

Marketing claims, checked

The checks, one by one

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

Partly confirmed1

“CERTIFIED”

“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.

?Couldn’t verify independently2

“In”

“Made in USA” can describe only final bottling. Ingredient-sourcing records were not located for this product.

Evidence →
“VITBOOST Biotin with Hyaluronic Acid, Collagen and Keratin – 25000 mcg Hair Growth Vitamins for Men and Women – Nails and Skin, USA Made - Third…”

No named laboratory or lot-specific certificate was found for this exact product. No exact brand product page was available for a document check. NSF, IFOS, USP, and Informed-Sport were not checked in this record. This is a public-evidence limit, not a finding that testing did not occur.

Evidence →

We looked and found no public proof. That does not count against the product.

Needs explanationIs the label honest?

Ingredient amounts are hidden inside “Proprietary Blend”

A blend total may be legal, but it prevents you from knowing whether any individual ingredient reaches a meaningful amount.

Evidence and sources

The panel lists “Proprietary Blend” (720 mg) as a combined amount. A blend total can’t tell you whether any single ingredient reaches a dose used in research.

What remains open 2
  • We have not found a public label filing for this exact product.
  • Barcode checksum is valid; no independent product record was found.

These are evidence gaps, not strikes against the product.

No official brand storefront is confirmed in this record. That is neutral, but it prevents a direct brand-price, label, review, and document check.
