iron proteinate
Iron proteinate is the chelated iron — the amino-acid-escorted form doing the same hemoglobin work with slightly smoother absorption.
Also appears on labels as: iron amino acid chelate · chelated iron · iron amino acid complex · ferrous chelate of amino acids hydrate
What it is
Iron bound to amino acids, the chelate pattern applied to the blood mineral. As with all proteinates: genuinely better-protected through digestion, modestly better absorbed, meaningfully more expensive.
Why it's in pet food
Iron delivery plus the premix-quality signal chelates carry. Recipes using proteinates across their trace minerals are usually telegraphing a formulation budget — a soft, honest signal among many.
How Bowlmark scores it
Scores are deterministic math over the printed label — the rules below apply to every product identically, and nothing estimates or fills in a blank.
Neutral, matching its sulfate sibling — the engine reads mineral adequacy as a formulation property, invisible to ingredient wording. The chelate-vs-inorganic choice is the premix chemist's, and both, done competently, feed the same red blood cells.
