Calcium Sulfate in Pet Food

Grade B-1 ptsNutrients

What It Is

"A calcium source and firming/binding agent, also known as gypsum."

Health Impact

Does double duty as a calcium source and a texture/binding agent, most often showing up in semi-moist or dental chew products where it helps hold the product's shape. Functional and safe, though it's doing a texture job as much as a nutrition job.

Why This Grade

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.
