🟡 Brewers Dried Yeast in Pet Food

Grade C-2.5 ptsNutrients

What It Is

"Dehydrated yeast recovered as a byproduct of beer brewing."

Health Impact

Nutritionally the same story as plain dried yeast — B vitamins, protein, and a savory flavor that boosts palatability — just sourced specifically from brewing rather than yeast grown for the purpose. The same caveat applies: legitimate for dogs without yeast sensitivities, but often included as much for taste as for nutrition. Score: 5/10.

Why This Grade

A real but unresolved concern: often an ongoing FDA/AAFCO research question (like the grain-free/DCM investigation), a common allergen, or a vague-but-not-alarming label claim. -2.5 pts deducted.
