Whey protein shortage looms as use of weight-loss drugs fuels global demand

Price of dairy product has risen fivefold after users of GLP-1 medications advised to increase protein consumption

The growing popularity of weight-loss drugs has fuelled global demand for whey protein, sparking concerns among industry experts over a potential shortage.

The price of whey has risen fivefold to record levels as companies race to secure supplies amid a boom driven by growing use of GLP-1 drugs, such as Mounjaro, which often require higher protein intake to preserve muscle mass.

Health advice emphasising protein consumption has also contributed to the rise in demand.

Whey protein is derived from milk during the cheese-making process. It contains all nine essential amino acids and is easily absorbed by the body, making it a popular, high-quality supplement for supporting muscle growth and recovery.

It has become particularly important for people taking GLP-1 weight-loss medications because these drugs can reduce appetite and lead to lower overall food intake. Health professionals often advise GLP-1 users to increase their protein consumption to help preserve muscle mass while losing weight.

Prices for food-grade whey powder across north-west Europe have risen to approximately €1,700 (£1,469) per tonne, the highest level on record . Since the start of the year, prices have increased by more than 50%, according to DCA Market Intelligence data.

Data from Vesper, a commodity intelligence platform for dairy, shows the price of a tonne of whey protein with a concentrate of 80% has risen from £4,302 in June 2023 to £23,751 in June this year.
