This site displays this specific fourth badge directly: FDA-Registered Facility — worth reading it alongside this site's own explicit statement that no dietary supplement is FDA-approved.
Dietary supplements are not FDA-approved the way medications are — an FDA-registered facility means the manufacturing site meets registration requirements, worth understanding as separate from any product-level approval.
This site links directly to the FDA's own dietary-supplements overview page as its source for this distinction — worth checking that primary source directly for the fullest, most current wording.
