In the fourth quarter of 2025, whey powder prices showed strong upward pressure in many markets. The increase was driven mainly by rising demand from fitness enthusiasts, health-conscious consumers, and older adults looking to maintain muscle mass. The popularity of high-protein diets and the growing use of weight-loss medications, which can reduce muscle mass, further fueled interest in whey protein, pushing buyers to secure supplies.
On the supply side, milk production was high in key regions, including the U.S., EU, and the UK, but processors faced challenges keeping up with the rapid growth in demand. Surplus milk sometimes led to stockpiling of whey and other dairy products, creating temporary imbalances in the market. At the same time, higher production costs for milk and dairy processing, including energy and labor, contributed to upward price pressure on whey powder.
Overall, Q4’25 saw whey powder prices climbing steadily, supported by strong consumer demand and the protein craze, even as milk supplies remained abundant.
