Checked against public sources on August 2, 2026 · LookCloser does not sell or recommend supplements.
Does the marketing hold up?
Every ingredient shows its amount · 4 ingredients listed. Every ingredient shows its real amount — nothing is hidden in a proprietary blend.
“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.

◐Partly confirmed1
Ingredient research can support context, but it is not a trial of this exact product.
△Claimed without support found1
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
“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.
