The soaring popularity of weight-loss drugs has driven a dramatic increase in global demand for whey protein, raising concerns about a potential shortage. Prices for whey have surged fivefold to record levels as companies compete for supplies, spurred by health advice for users of GLP-1 medications like Mounjaro to boost protein intake to preserve muscle mass.
Whey protein, a byproduct of cheese production, is valued for its complete amino acid profile and easy absorption. Its demand has risen sharply as GLP-1 drugs reduce appetite, leading to lower food consumption. Health professionals often recommend increased protein for these users to maintain muscle during weight loss.
Data from DCA Market Intelligence shows food-grade whey powder prices in northwest Europe have hit approximately €1,700 (£1,469) per tonne, the highest ever, with a 50% increase since January. Vesper, a dairy commodity intelligence platform, reports that the price of 80% whey protein concentrate rose from £4,302 per tonne in June 2023 to £23,751 in June 2024.
Jasper Endlich, an analyst at Vesper, noted a clear shortage: “Manufacturers would like to produce more and build safety stocks, but they haven’t been able to.” He added that new production plants are opening, and some companies are using blends with milk protein to cut costs while maintaining protein content.
A US Department of Agriculture report highlights tightening supplies, particularly for whey protein concentrate (WPC) 34%, with some suppliers sold out through 2026. One manufacturer is expected to stop producing WPC 34% after summer, further reducing availability. Small businesses are struggling; Erika Tamayo, founder of protein brand Hermosa, said she now pays double for ingredients compared to last quarter and faces challenges securing stock.
Tamayo added that the GLP-1 boom has led to whey protein being added to many products, from popcorn to doughnuts. “The challenge is managing lead times and availability,” she said, noting that she buys months in advance to avoid running out.
