America is running low on whey protein.
The latest: US whey protein inventories have fallen by half since 2023, while prices have surged more than 50% since January.
Beefed up. From sports nutrition staple to mainstream macro, protein mania has reached an all-time high — with ~70% of younger consumers actively trying to eat more protein.

Accelerating demand, GLP-1 users and longevity-seekers view muscle as a vital sign — not just an aesthetic flex. Cashing in, Big Food and emerging brands are packing protein into everything from bars and shakes to coffee, cookies, and chips.
Supply crunch. Under pressure, some whey suppliers are already sold out for the rest of the year, forcing manufacturers to raise prices, reformulate products, or seek alternatives like soy and milk protein.
Takeaway: Now that protein’s journey from weight room to grocery aisle is complete, the only barrier to a continued boom is finding enough whey to fuel it.
