America’s growing appetite for protein is creating pressure across food and beverage supply chains, as a looming shortage of whey protein concentrate threatens one of the country’s strongest consumer trends.
Once considered a low-cost byproduct of cheese production, whey protein concentrate has become one of the most sought-after ingredients for brands looking to launch or expand high-protein products.
Demand has grown so quickly that some suppliers are already sold out for the rest of the year, according to the US Department of Agriculture.
Prices are rising sharply. DCA Market Intelligence said standard whey powder prices have increased by more than 50% since January. Higher-protein powders are even more expensive, with 80% whey protein concentrate trading above $11 and protein isolate, which contains more than 90% protein by weight, holding around $12, according to the USDA.
BellRing Brands, owner of Premier Protein and Dymatize, said whey prices have reached record levels. CEO Darcy Davenport said the shortage is also affecting nonfat dry milk, another key ingredient in protein drinks.
Protein has become a major growth driver in the food industry. According to the International Food Information Council, 70% of Americans want to consume more protein, up from 59% four years ago.
The rise of GLP-1 weight-loss drugs has added further momentum, as consumers using these treatments often eat less and look for more protein to support nutrition.
Protein is now appearing across supermarket categories, from Pop-Tarts and Kraft macaroni and cheese to Doritos. For many food companies, adding protein has become a way to revive sales and justify higher prices.
The dairy industry is investing to expand capacity, but scaling production is complex. Increased whey protein production also creates more butterfat, another byproduct, which has contributed to oversupply and price volatility.
The International Dairy Foods Association said US dairy producers have invested $11bn in new and expanded capacity across 19 states. The group expects US milk production to rise by 15bn pounds by 2030 to meet protein demand.
Companies now face a difficult choice: raise prices at a time when consumers are already under inflation pressure, or reformulate products using cheaper alternatives such as soy or pea protein.
Davenport said at least one major protein competitor has already announced a significant price increase, and BellRing is evaluating whether to follow.
