Whey protein prices surge as Greek suppliers face tight European availability

Demand expands beyond sports nutrition

Whey protein has moved from a specialist sports supplement into everyday diets in Greece, supporting demand for powders, drinks, puddings and other high-protein foods. Greek companies told newmoney that buyers now include men and women across different age groups, rather than primarily gym users and professional athletes.

Petros Pelkas, head of Giannitsa-based Tesoro, said market activity and demand had been particularly strong over the past two years. Antonis Foustaniás, founder and CEO of biologos, linked the broader interest to consumers’ focus on adequate protein intake, muscle preservation, healthy ageing and weight management. He also pointed to the widespread use of GLP-1 therapies: because these treatments reduce appetite and food intake, nutrition quality and sufficient protein consumption receive greater attention under medical supervision. Social-media fitness content and protein recipes on TikTok and Instagram have added to demand.

Raw-material prices rise faster than supply

Supply has not adjusted at the same speed. Whey is a by-product of cheese manufacturing, so its availability depends on milk output and, more directly, on the volume of cheese produced. Dairy companies have not increased cheese production at a rate matching global whey demand. Market research company Vesper said whey protein prices increased fivefold over the three years through June because of shortages. Expana data cited by newmoney showed that the average European whey protein price had quadrupled compared with three years earlier and was 130% higher year on year in late August.

Production constraints extend beyond the availability of liquid whey. The raw material contains substantial water and a relatively low concentration of protein. Producing a high-protein grade such as WPC80 requires large volumes of whey, followed by filtration and separation to remove much of the lactose, minerals and water. The protein is then concentrated and dried into powder. Output therefore depends both on cheese-derived whey and on processing capacity, neither of which can expand immediately when consumer demand rises.

Greece produces only a small amount of whey, leaving domestic manufacturers dependent on established suppliers in Germany, Italy and Poland. Greek businesses said those countries can still provide raw material, but recent deliveries have sometimes been delayed. Companies are consequently building inventories earlier and trying to anticipate consumer trends so they can secure supplies before competitors.

Greek companies absorb part of the cost

For processors and manufacturers of finished protein products, the speed of the cost increase has been as difficult as its size. Foustaniás said companies faced a sharply different production-cost base within a short period and could not immediately pass the full increase to consumers. Producers absorbed a significant share, squeezing margins while availability of particular whey grades became tighter and procurement planning grew more difficult.

Tesoro nevertheless raised the price of whey, its best-selling product, to preserve its existing formulation as input costs climbed. Pelkas said expensive raw materials can still be sourced, but companies must both locate the limited supply and be able to pay for it. This leaves retailers and brands balancing affordability against product consistency, while consumers see higher shelf prices without necessarily seeing the international raw-material constraints behind them.

Industry participants expect new factories to be developed over the next one to two years in response to the shortage. Additional processing capacity could gradually improve supply and return prices to more normal levels. Until then, Greek companies remain exposed to European availability, delivery delays and competition for costly whey inputs, even as consumer demand shows signs of extending beyond a temporary fitness trend.
