Nationwide Whey Supplier & Distributor Services
Diversified Ingredients is a wholesale whey supplier and distributor serving food, feed, sports nutrition, supplement, and pet food manufacturers across the United States through our Preston Protein Products division. Diversified Ingredients is a whey supplier and distributor offering WPC, WPI, sweet whey, and permeate to food, feed, sports nutrition, and pet food manufacturers across the country.
We are a whey supplier with nationwide reach. Whether customers describe us as a whey supplier, whey protein distributor, whey manufacturer, or whey distributor — the operation is the same. Our Preston Protein Products division has been processing dairy since 1910, and joined Diversified Ingredients in 2020. Our combined teams support customers nationwide with sourcing, processing, drying, and functional whey blend production.
Sourcing whey carries real pressure. Markets shift. Whey prices climb without warning. Spec sheets get challenged at audit. Tankers run late. Allergen documentation gets requested at the worst possible moment. We get it. Our team has spent decades inside the dairy products sector to keep customer formulations on track.
