The protein craze that has food and beverage makers adding extra grams to everything from chips, waffles, and cold foam has met its match. There isn't enough whey protein to go around.
Some suppliers are already sold out for the remainder of the year, and offers for high-protein whey concentrate have jumped more than 40% on average in the past couple of months, the Financial Post reports.
Because whey is a byproduct of cheese production, processors can't ramp up protein output without making more cheese. Agri-Mark commodity and dairy sales executive Bryan Weller describes the resulting mindset shift to the Financial Post: "You start to think of yourself as a protein company, not a cheese company."
The price data shows how far the market has moved. DCA Market Intelligence reports food-grade whey powder reaching roughly $1,960 per ton, the highest level on record and up more than 50% since the start of 2026.
According to USDA Dairy Market News, high-protein whey concentrate is priced between $9.75 and $11.00 per pound and whey protein isolate remains firmly in the $12 range.
The strain is already reshaping production. Some manufacturers have halted output or reformulated flagship products. The Financial Post reported that Canada-based HelloAmino, which uses whey across all 30 of its high-protein baking mixes, sourced isolate from the U.S. at a 50% premium after a supplier ran out—only to find the new powder dried out its baked goods.
Other food processors are turning to alternative ingredients to avoid rising costs. Using different protein sources such as milk protein concentrate, soy, and pea proteins can help food processors keep formulations on shelves.
However, the dairy industry is racing to meet supply demands and add capacity.
Reported growth and expansion plans from U.S. dairy producers aim to increase the future supply of whey protein. According to the International Dairy Foods Association (IDFA) dairy processors are responding to surging demand for their products by investing more than $11 billion in new and expanded manufacturing capacity across 19 states. The IDFA says it expects U.S. milk production to grow by 15 billion pounds by 2030 to meet demand for protein.
