Whey protein has long been the default in sports nutrition for its fast absorption, ideal for the post-workout market it built its reputation on. But with prices elevated for several years running, and the average protein consumer no longer just a post-workout crowd, brands are increasingly reformulating around blends instead of whey alone.
The list of ingredients showing up in those blends is long: MPC85, MPI90, egg albumin, micellar casein, calcium caseinate, ultrafiltered milk, and lower grades of whey protein concentrate such as WPC70, WPC60 and WPC50. Vegetable proteins like pea, soy and rice appear less often, held back by taste, but the dairy-derived alternatives carry protein content close to WPC80 or even whey protein isolate at a fraction of the price, in some cases as little as half.
The shift is still playing out rather than settled. Producers have kept adding whey capacity even as buyers look for ways around it, and where the resulting supply and demand balance lands should become clearer over the next few weeks.
The underlying dairy market is doing its part to keep the pressure on whey-heavy formulations. US butter fell another 5% week on week as global milkfat supply stays ample, a decline reinforced by a fresh drop in this week’s GDT auction prices. Nonfat dry milk moved the opposite way, up 5% week on week, as processors increasingly favor selling fresh and ultrafiltered milk over running it through the drying tower. That split between falling fat prices and firming protein prices for milk powder echoes a pattern seen earlier this year, when it took several months for the balance to unwind.
For buyers still committed to whey, the reformulation trend happening around them is worth watching closely: every brand that successfully substitutes even part of its whey content changes the demand side of a market that’s been short on relief.
