“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.

NUSAVA (2 Pack) Vitamin B12 Liquid Drops with B6
Checked against public sources between July 21 and September 3, 2026 · LookCloser does not sell or recommend supplements.
Does the marketing hold up?
Package and trademark records name different responsible entities. The package says manufactured for: Nusava, 3746 Foothill Blvd #7096, Glendale, CA 91214. USPTO names PREMIEREPET PARTNERS LLC as the exact wordmark owner. …
“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.
