Checked against public sources between July 21 and July 24, 2026 · LookCloser does not sell or recommend supplements.
Does the marketing hold up?
1 ingredient’ amounts are hidden inside “Advanced Hair Complex”. The label gives one combined figure of 160 mg for Arginine Silicate Inositol (Providing 10 mg Silicon), Magnesium Biotinate, and no amount for any of them individually. …
“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.
What the Supplement Facts panel says
| Biotin | 10,000 mcg |
|---|---|
| Advanced Hair Complex | 160 mg |
| Arginine Silicate Inositol (Providing 10 mg Silicon), Magnesium Biotinate | not stated separately |
The label groups several ingredients under “Advanced Hair Complex” and publishes only the combined total, so there is no way to tell how much of each one a serving contains. That is the manufacturer’s choice, not a gap in our reading.
Printed on the package: ADVANCED HAIR COMPLEX · Non-GMO
