The cost of whey, a key ingredient in protein powders, has skyrocketed by over 100% in the past five years, according to a local manufacturer. This surge in prices is driven by a surge in demand for protein-enhanced products, fueled by Australia’s booming gym culture.
Powerlifting coach Cam Brown has noticed protein supplements becoming increasingly expensive, particularly over the last couple of years. “Even in the shops, there’s a lot more protein products there,” he said. “People have changed their viewpoint that protein powders are only for bodybuilders.”
Supplement companies have reported significant increases in the retail prices of whey protein, even as the prices of other dairy products have become cheaper. Experts attribute this to a supply-demand imbalance, with not enough whey protein being produced to keep up with the rising demand for protein powders and other protein-enhanced products.
Bulk Nutrients, a prominent fitness brand, has had to raise the prices of its whey protein concentrate and isolate by 11.36% and 17.24%, respectively, far outpacing Australia’s overall inflation rate of 3.4% and the 3.2% inflation in dairy products.
“There’s not enough [whey] to meet the demand for all products that want to use whey protein,” said Jess Crowley, the CEO of Bulk Nutrients. “There’s just a lot more people competing for a limited amount of stock. We’re finding these are the highest prices that we’ve ever paid.”
The surge in demand for protein supplements is partly driven by the popularity of GLP-1 medications for weight loss, as people seek to take them while consuming fewer carbohydrates. Additionally, the increasing cost of farming cattle, climate change, global economic instability, and the weak Australian dollar have all contributed to the higher prices.
Michael Whitehead, the ANZ executive director for agribusiness industry insights, explained that whey prices are more affected by the global dairy trade than the Australian farm-gate price. From August 2024 to December 2025, the price of whey went up 52%, while cheese only increased by 8%.
“Consumers in Australia and so many markets, as society tries to become healthier, are thinking ‘protein, protein, protein’,” Whitehead said. “It’s just that big demand.”
The rise in protein-enhanced products, such as yogurt, smoothies, muesli bars, bread, and peanut butter, has been accompanied by a decline in traditional milk consumption. However, while the prices of other dairy products like butter have come down, the cost of whey protein concentrate and isolate has continued to climb to record levels.
