WHITEPAPER | 2026
GLP-1 is rewriting demand for dairy protein, and prices have roughly tripled.
Whey protein has climbed to levels the market has not seen before. The move lines up with a shift in demand, not a poor season. GLP-1 weight-management medication, alongside a wider "protein-first" change in the food basket, has built a consumer base for whey that is larger, less seasonal and less price-sensitive than before. At the same time, supply has been slow to catch up, held back by long lead times in high-protein processing.

"Whey proteins are no longer a sports-nutrition story. Medical applications, weight management and general food fortification have created a consumption base that is far less seasonal and far less vulnerable to slowdowns in consumer demand."
