whey protein concentrate

What it is

Whey filtered and concentrated so protein dominates and most lactose is removed — the same ingredient sold as human sports nutrition. Whey protein is rich in essential amino acids (notably leucine and cysteine) and highly digestible; isolates push protein higher still.

Why it's in pet food

Protein fortification in treats, toppers, and supplements — especially recipes courting the "recovery" and "senior muscle" briefs. Unlike dried whey, it brings the protein without most of the lactose, which is exactly why formulators pay more for it.

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.

Engine-neutral: no bonus, no deduction, any position. The named-protein bonus is reserved for named ANIMAL-flesh proteins (chicken, salmon, egg…) leading a list, a slot a dairy protein powder doesn't occupy in complete foods. The engine scores what's on the label; the quality nuance between whey forms lives here.

No food on the shelf lists whey protein concentrate yet. Scan a bag that does and its label joins the catalog — versioned from the day it arrives.
