This site's own quality badge states this directly: processed under strict standards. Not FDA-approved.
Dietary supplements are not FDA-approved the way medications are — this site names both halves of that distinction directly on its own badge, worth reading as a specific, checkable claim about facility registration rather than product endorsement.
Including the words "Not FDA-approved" directly on a manufacturing badge, rather than only in fine-print disclaimers, is a more upfront framing than many similar sites in this category use.
