Retail sales of protein products climbed steadily through late 2025, underscoring a robust appetite that defies predictions of market saturation.[1][2]
Sales Data Signals Ongoing Expansion
Animal-based proteins posted impressive gains across multiple channels in the year ending November 2025. SPINS data revealed a 27.3% increase in multi-outlet sales to $1.5 billion, while natural channels saw 22.7% growth to $18 million.[1] Whey protein led the charge with 24.4% growth in multi-outlet to $355.5 million and even stronger performance in specialized categories.
Casein followed suit, rising 25.8% overall despite a dip in performance nutrition segments. Analysts attributed this resilience to protein’s positive perception and broad availability. Standalone whey products expanded 14.4% in multi-outlet sales to $687 million. Such figures prompted experts to dismiss talk of a peak.
Consumers Embrace Protein for Health Goals
Seventy percent of Americans sought higher protein intake in 2025, up slightly from 67% two years prior, according to IFIC surveys.[1] Media coverage, GLP-1 medications, and healthy aging concerns drove this shift. Many turned to friends and family for advice amid confusion over daily needs.
New USDA guidelines released in January 2026 recommended 1.2 to 1.6 grams per kilogram of body weight daily, spread across meals.[1] Half of Gen Z and Millennials pursued protein-enriched functional foods. Cargill’s report noted 61% of consumers ate more protein in 2024 than five years earlier, with parents willing to pay premiums.[2]
Innovations Cater to Evolving Demands
Manufacturers targeted GLP-1 users with slow-release caseinates for prolonged satiety and muscle support. FrieslandCampina highlighted these in their 2026 trends report, expanding into treats and ready-to-drink formats.[1] Arla Foods Ingredients promoted leucine-rich whey for everyday beverages like sodas.
Protein appeared in nontraditional spots, from snacks to coffee. Plant-based options stabilized after an early surge, yielding ground to whey for its mixability and flavor. Experts like Dicker observed, “We continue to see it grow either in high single digits or low double digits, year after year, showing we have not yet hit peak protein.”[1]
Key Growth Drivers at a Glance
- Whey protein: 24.4% multi-outlet growth to $355.5 million.[1]
- Casein: 25.8% rise to $231 million, boosted by immune health applications.
- Consumer intent: 70% aiming for more protein, per IFIC.[1]
- Meat demand: Per-person consumption projected to hit 122 kg by 2027.[2]
- GLP-1 influence: High-protein dips up 30%, fiber pairings rising.[2]
Key Takeaways
