If your protein tub costs more than it did last year, you're not imagining it. Wholesale whey prices hit record highs in 2026. The biggest new driver isn't bodybuilders. It's the millions of people now taking GLP-1 weight-loss drugs like Ozempic and Wegovy.
Here's what's going on, how long it's expected to last, and the one number to check before you buy your next tub.
The short answer
Whey is a by-product of cheese, so supply can't grow quickly. Demand has jumped, partly because GLP-1 users are told to eat more protein. Ingredient prices hit records this year, and dairy economists expect them to stay high through at least the end of 2026.

What happened to whey?
Whey is the liquid left over when milk is turned into cheese. For decades there was more of it than anyone needed, so it was cheap. That's why a scoop of whey became the easiest way to hit your daily protein goal.
That math has flipped. You can't make more whey without making more cheese, and cheese output doesn't jump just because protein is popular. Meanwhile, food companies now put whey into bars, chips, coffee drinks and "high-protein" everything. Your tub is competing with all of them for the same limited supply.
The industry has noticed. Market analysts describe whey as having gone from a by-product to an ingredient with its own demand, and some suppliers have said they're struggling to keep enough in stock for the rest of the year.
How GLP-1 drugs changed the protein market
GLP-1 medications reduce appetite, so people taking them eat a lot less. The risk is that some of the weight they lose is muscle. That's why people on these drugs are commonly advised to prioritize protein: it helps them feel full and hold on to lean mass.
Roughly 1 in 9 American adults now take one of these drugs. When they eat less overall, a protein shake is one of the easiest ways to get enough protein. That's a huge wave of new buyers reaching for the same whey that lifters have always used.
What this means for you: you're now sharing the protein aisle with a much bigger crowd. Popular flavors and sizes may sell out faster, and brands may shrink tub sizes or raise prices as their contracts renew.
Will prices come down?
Not soon. Some prices have eased slightly from their summer peaks, but they're still well above historical averages. Dairy economists expect high whey prices to hold through at least the end of 2026.
The good news is that retail prices don't move one-for-one with ingredient prices. A doubling at the wholesale level doesn't mean your tub will cost twice as much. Brands with longer supply contracts or bigger buying power can hold their prices longer, which is why the brands on the shelf are pricing so differently right now.
The number that actually matters
When prices shift this fast, the sticker price on the tub tells you very little. A cheaper tub can have fewer servings, smaller scoops or less protein per scoop. Compare cost per gram of protein instead. It takes 30 seconds:
The 30-second label check
Price ÷ (servings × grams of protein per serving) = cost per gram
Example: a $60 tub with 30 servings of 25 g protein
$60 ÷ (30 × 25 g) = $60 ÷ 750 g = $0.08 per gram
That works out to about $2.00 for every 25 g of protein. Or skip the math and try it with the tub you have at home:
Cost per gram of protein
Example values. Swap in the numbers from your label.
Three more things to check on the label while you're at it:
- Protein per scoop, not scoop size. A 40 g scoop might only deliver 22 g of protein. The rest is carbs, fat, flavoring and sometimes filler.
- Isolate vs concentrate. Isolate is more filtered, so it's higher in protein and lower in lactose, but it's also the ingredient that has jumped the most. If you digest concentrate fine, a blend can be the better value.
- Third-party testing. Look for Informed Choice, NSF Certified for Sport or similar seals, especially if you compete or get drug tested.

The bottom line
Whey isn't going anywhere, but the days of cheap protein powder are on pause. GLP-1 users, food companies and lifters are all competing for a supply that can only grow as fast as cheese production. Until that changes, compare cost per gram instead of tub price, match the protein type to what your body actually needs, and stock up when you find a deal.
