Mineral premix

Also appears on labels as: minerals, vitamins & minerals, vitamin & mineral blend, proprietary vitamin and mineral mix

The trace mineral package: zinc, iron, copper, manganese, selenium, and iodine, each bound to a sulfate, oxide, or an amino acid.

Watched ingredients get highlighted on every product panel you open.

Where it comes from
Premix manufacturers.
Why it's in the product
Supplies the trace minerals a food's raw ingredients cannot reliably deliver at the right ratios.
Safety and toxicity
Safe and required. The form matters more than the presence: proteinates and amino acid chelates are absorbed better than oxides, so a premix full of proteinates is a small quality signal.
Interactions and who should be careful
Zinc, copper, and iron compete for absorption with each other, which is precisely why the ratios in a formulated premix are worth more than a supplement you add yourself.

General reference, not veterinary advice. Dose, breed, and existing conditions change the answer, so talk to your vet before changing what your pet eats. Think we got this wrong? Tell us and we log it publicly.
