Checked against public sources on July 25, 2026 · LookCloser does not sell or recommend supplements.
Does the marketing hold up?
🇺🇸 Brand owner: Dexterity Health, LLC · limited liability company, NEW JERSEY, USA This tells you who is behind the brand and where the trademark record points. It does not by itself identify the manufacturer.
“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.
