Wisconsin Whey Protein

What Wisconsin Whey Protein does

Wisconsin Whey Protein is a B2B dairy ingredient manufacturer founded in 2010 and headquartered in Darlington, Wisconsin, with a second production site in Turtle Lake, Wisconsin. The company produces whey protein isolates (WPI 90%, WPI 94%), whey protein concentrates (WPC 34%, WPC 80%, including heat-stable and low-spore variants), premium refined and ultra-white lactose in multiple mesh grades, and White Cheddar and Parmesan cheeses. Manufacturing relies on proprietary crossflow membrane filtration applied to sweet whey, cold processing to preserve bioactive proteins, gentle spray drying, and non-GMO sunflower lecithin for instantization. The company operates what it describes as one of Wisconsin's largest single-site cheese and whey manufacturing facilities.

The company's go-to-market is a direct, quote-based B2B ingredient supplier model targeting food and nutrition manufacturers across four core end markets: sports/active nutrition, infant nutrition, medical nutrition, and pharmaceutical/cheese applications. Pricing is not publicly disclosed; orders are bulk industrial format (20kg bags, 25kg bags, 500lb barrels, 40lb blocks, 1 metric ton totes) under multi-year contracts. The company maintains a broad certification stack including SQF food safety, EU and IMS registration, r-BST free, ISA Halal, and UM Kosher, which is a prerequisite for selling into infant formula and pharmaceutical-grade channels.

In December 2025, Royal FrieslandCampina N.V. acquired Wisconsin Whey Protein and integrated it into FrieslandCampina Ingredients, describing the deal as its largest ingredients investment since its 2008 merger. The acquisition more than doubled Wisconsin Whey Protein's whey isolate capacity and triggered a simultaneous doubling of factory capacity, supported by a €90 million FrieslandCampina investment in its broader whey protein production network. Post-acquisition, the business now sells through FrieslandCampina's global distribution network and is positioned as the parent's North American protein platform with ambitions to reach top-three share in performance and active nutrition.
