Watch for Synthetic addition signals a formulation gap to fill

Because ingredients are listed by weight before processing, taurine can rank above or below other components purely on water content. Compare dry-matter contributions, not list order, when judging how much protein actually reaches the bowl.

How to read it on a label

  • Named is better: a species name (chicken, salmon, lamb) beats a category (meat, poultry, animal).
  • Split listing: peas, pea protein and pea fiber are one ingredient counted three times.
  • Percentage claims: ‘with real chicken’ legally needs very little chicken; ‘chicken first’ needs only the largest single share.

For taurine specifically: synthetic addition signals a formulation gap to fill.

Practical takeaway

Taurine is a supporting ingredient rather than a selling point. Judge the formula by total protein, fat and the AAFCO statement; single ingredients rarely decide quality on their own.

Bottom line: taurine is fiber & extras with a 0% protein protein contribution — useful, but only one line in a longer calculation.
