Does the marketing hold up?
Ingredient amounts are hidden inside “Ultimate Hair Health Complex”. The panel lists “Ultimate Hair Health Complex” (1,662 mg) as a combined amount. A blend total can’t tell you whether any single ingredient reaches a dose used in research.

Evidence →No named laboratory or lot-specific certificate was found for this exact product. No exact brand product page was available for a document check. Under NSF/ANSI 173, NSF lists Codeage LLC products, including Liposomal Glutathione 1000mg (powder), but not this exact SKU. 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.
We looked and found no public proof. That does not count against the product.

The label promise and the Supplement Facts amount agree.
Evidence and sources
The listing claims 10 mg; the photo-read Supplement Facts panel shows Biotin at 10 mg per serving — the listing text and its photo-read panel agree; this is internal consistency, not independent testing.

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 20 mg of zinc per serving. Studies we found used 8 mg–40 mg a day, so this sits inside that range.
0studied 8 mg–40 mg
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
