This site states this directly on its own quality badge: brand describes a naturally sourced formula; we could not independently verify the complete ingredient list.
Unlike the other three badges, which each address a distinct manufacturing claim, this one pairs the "naturally sourced" claim directly with the site's central transparency gap — worth reading both halves of this one sentence together.
Worth noting that "naturally sourced" is difficult to meaningfully evaluate without knowing which specific ingredients are being described that way — this site's own admission makes that limitation explicit rather than glossing over it.
