"An inorganic zinc source used to meet mineral requirements."
A functional, inexpensive zinc source, but generally regarded as the least bioavailable common form — less readily absorbed than zinc sulfate, and well behind a chelated or proteinate form. Safe at the levels used in pet food; simply the most basic version of zinc supplementation available.
A minor caveat applies — usually a processing step (e.g. rendering into a meal), a moderate allergen history, or a named-but-fattier source — but nothing on our risk watchlist. -1 pt deducted.
