This site states this specific phrase directly, closing its own label-transparency section: worth knowing before you buy — if this information is difficult to find on the packaging or official checkout page, treat that as a reason for caution.
Rather than ending the checklist on a neutral note, this site closes with a direct instruction on how to act if the information isn't findable — worth reading that as this site's own practical bottom line, not just a list of items to check.
Worth reading this caution alongside this site's own admission that it couldn't confirm SodaPeak's complete ingredient list — worth applying the same caution this site recommends to the product it's reviewing.
