Name: Kirkland Signature Protein Bar, Chocolate Brownie
Brand: Kirkland

Munch or Dump rates Kirkland Signature Protein Bar, Chocolate Brownie by Kirkland ENGINEERED — score 30/90.

A lab-built macro bar: isolated protein powders, tapioca-derived fiber, and a stacked sweetener system (erythritol + stevia) engineered to hit 21g protein and 1g sugar. Impressive on paper, but this is a formulated supplement, not real food.

Why this verdict

Two isolated protein powders (whey + milk isolate) form the base, not real food
Dietary fiber from tapioca starch is a processed fiber that inflates numbers and can cause gas and bloating
Two stacked non-nutritive sweeteners: erythritol plus steviol glycosides
Sunflower lecithin emulsifier and alkalized cocoa signal a lab-formulated bar
NOVA 4 ultra-processed despite the clean-label marketing

Ingredients (11)

Whey protein isolate + milk protein isolate blend (moderate) — Isolated, highly refined protein powders. Effective for muscle repair but a manufactured ingredient, not whole food.
Dietary fiber from tapioca starch (moderate) — A processed soluble fiber used to bulk the bar and inflate fiber counts; commonly causes bloating, gas, and GI discomfort.
Cashews (safe) — A genuine whole-food ingredient adding healthy fats and texture.
unsweetened chocolate++ (safe) — Real chocolate with cocoa solids; a positive whole ingredient.
Erythritol (moderate) — Sugar alcohol sweetener; largely calorie-free but recent studies link high blood levels to cardiovascular concerns, and it can cause GI upset.
Cocoa powder (processed with alkali) (moderate) — Alkalized (Dutched) cocoa; fine for flavor but the alkali process strips much of the beneficial flavanols.
Natural Flavors (moderate) — Undisclosed proprietary flavor compounds; a hallmark of engineered, formulated food.
Cocoa Butter (safe) — Natural fat from the cocoa bean; a clean ingredient.
Sea Salt (safe) — Standard seasoning in small amounts.
Sunflower Lecithin (moderate) — An emulsifier used to bind the bar; generally recognized as safe but a marker of processed formulation.
Steviol glycosides (stevia) (moderate) — A second non-nutritive sweetener stacked with erythritol; the double-sweetener system is a sign of engineered sweetness.
