Just got back from a trip to Portugal and Spain, and like any CPG enthusiast, I couldn’t help but wander through the local grocery stores. When you spend your life looking at retail shelves, you notice things. Here are 4 stark differences I observed between the US and European functional food landscapes—backed by the numbers: 1. Private Label Dominance is Next-Level In the US, walking down the protein bar aisle means looking at a wall of venture-backed or massive corporate brands. In Iberia? Retailer own-brands rule. 🔹The Data: According to recent 2026 Circana data, private label unit share has reached a staggering 59% in Spain. By comparison, US private label grocery unit share typically hovers around 23%. European retailers have successfully premiumized their store brands, moving them far beyond the "cheap generic" stigma. 2. The "Bar Aisle" Simply Doesn't Exist If you’re expecting a 20-foot destination aisle packed with 50 different protein bar brands like at a Kroger Target, you’re out of luck. In most Iberian supermarkets, the bar selection is compressed into roughly two shelves, spanning about 4 feet long. The category simply doesn't command the same massive physical footprint. 3. Formulation & Radically Different Transparency The structural makeup of European bars tells a completely different macro story: 🔹The Binders: While US bars heavily rely on soluble tapioca fiber or corn fiber to keep bars soft and lower net carbs, European bars lean heavily into sugar alcohols—specifically maltitol—as the main binder. 🔹Plant-Based Deficit: The plant-based protein bar movement is noticeably smaller over there; dairy-derived proteins still reign supreme. 🔹Radical Transparency: Thanks to Europe's QUID (Quantitative Ingredient Declaration) regulations, brands are legally required to list the exact percentage of key ingredients highlighted on the package. You don't just see "almonds" on the label; it explicitly states "Almonds (25%)". 4. My Theory: The High-Protein Shift to Dairy & Fresh RTE Why is the bar aisle so small? Because Europeans are getting their portable protein fix elsewhere in the store: 🔹The Massive Yogurt Aisle: The functional dairy footprint is massive. Retailers like Mercadona have entire bays dedicated to high-protein puddings, mousses, and Greek yogurts (like their hyper-popular +Proteínas line). 🔹High-Protein Ready Meals: The Ready-to-Eat (RTE) chilled meals aisle is booming in Europe, with a massive pivot toward clean, high-protein fresh entrees (think chilled lentils with chicken, or protein-enriched fresh pastas) over shelf-stable snack bars. The Takeaway: The US looks at protein through a "snackified, shelf-stable, low-net-carb" lens. Europe looks at it through a "fresh dairy, clean whole food, and macro-balanced meal" lens. To my fellow grocery nerds and CPG founders: Have you noticed this shift when traveling abroad? Is the US over-indexing on bars, or is Europe missing a massive ambient snack opportunity?
Very interesting observations, Jonathan. I fully agree that Europe is structurally different from the US. From my perspective, working with functional snacks and private label in Europe, the big opportunity is not to copy the US “bar aisle” model — but to build smarter, more retail-adapted formats. Europe is highly private-label driven, margin-focused, and much more controlled by retailer concepts. That means successful protein snacks here need to be: • clean and transparent • price-efficient • easy to merchandise • strong in taste • adapted for retailer own-brand strategies I also think ambient functional snacks are still underdeveloped in Europe. The demand is there, but the format, price point, and shelf execution need to fit the European retail reality. /Thobias
Grew up in Germany, lived in different European countries after. Now I work with US manufacturers. Rewe and Netto never carried the "cheap generic" stigma the US private-label shelf still has. A lot of German store brands come off the same line as the name brand next to them, with the recipe nudged slightly so it's not the same product at two prices. That's a manufacturing decision before it's ever a shelf decision. Same logic applies to QUID. A US label formulation gets built around what's legally allowed to stay vague. Take that away and the bar itself changes, not just the front-of-pack copy.

Great observation though! The private label gap tells the whole story. 59% in Europe means shoppers trust the retailer brand as much as the national brand. US shoppers at 25% still lean on brand equity to make decisions. That changes everything about how you price, position, and pitch to buyers on each side. A US brand entering Europe with the same margin structure and the same retail pitch is walking into a completely different game.
Jonathan - I just got back from Lima, Peru. Peru has been updating the ingredient packaging for several years now. I believe they have the U.S. standards in most major food chains.

The US has completely overdone it with protein in general. Look no further than Protein Doritos. I love that Europeans get their protein from real food.
One additional difference is the role of the retailer itself. In much of Europe, retailers actively shape category development through strong private-label programs, which influences assortment, shelf space, and innovation priorities. That helps explain why protein bars occupy a smaller footprint while high-protein dairy and fresh ready-to-eat products receive greater emphasis. Ultimately, the category mix reflects not just consumer preferences, but also how retailers choose to allocate space based on shopping missions, margins, and purchase frequency.
