"An inorganic iron source used to meet mineral requirements."
A standard, effective iron source, though — like other sulfate mineral forms — less bioavailable than an amino-acid-chelated version. Safe and common at the levels used in pet food.
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.
