Checked against public sources on July 31, 2026 · LookCloser does not sell or recommend supplements.

Package and trademark records name different responsible entities. The package says manufactured for: Quality Supplements and Vitamins, Inc., Ft. Lauderdale, Florida 33309. USPTO names Life Extension Foundation, Inc. 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.
