Protein has evolved from a niche nutrition claim into one of the food and beverage industry’s most influential purchase drivers.
Consumers are seeking products that deliver more protein, which is in turn driving premiumisation across categories from beverage to snacks.
And few categories are better-placed to capitalise on this shift than dairy. In recent years, the category has become a home for protein innovation, having already benefitted from its natural nutritional credentials and established links to gut health and satiety.
Manufacturers are racing to innovate across multiple segments, from mainstream value-added products to premium high-protein propositions and even specialist sports nutrition solutions.
The opportunity is becoming so lucrative that competition is reaching new levels of intensity. Leading players Danone and Chobani have even clashed in court over protein claims, highlighting that the battle for market share increasingly comes down to how much protein a product can credibly promise.
High-protein dairy outpaces the wider market
Dairy products that carry protein claims now represent a $10.4bn segment within the $104bn US dairy market, according to Circana retail data.
Crucially, these products dramatically outperform the rest of the category. Over the past year, dairy products with protein call-outs grew 13.7% in value and 7.5% in volume, compared with just 2.0% and 0.3% respectively for the broader dairy segment.
In other words, protein is not simply driving value, but it is now a leading category growth driver, according to the data.
How protein claims are reshaping dairy
Across categories, yogurt remains the biggest beneficiary of the protein trend in dairy. While the broader yogurt segments also continues to perform strongly, protein yogurt is accelerating even faster - with sales climbing 23.2% in value and 16.8% in volume, ahead of conventional yogurt at 12.2% and 7.3%, respectively.
Cottage cheese is another standout success story. Already enjoying renewed consumer interest, the category is receiving an additional boost from protein positioning. Products making protein claims grew 18.1% in value and 14.6% in volume, outperforming overall cottage cheese growth of 16.5% and 12.0%.
Even milk, which has struggled due to long-term consumption declines, is seeing protein reverse the trend. Conventional dairy milk has remained largely flat, but high-protein milk recorded 7.7% value growth and 1.2% volume growth, demonstrating how protein claims can reinvigorate a mature category.
The rise of multi-benefit dairy
But protein isn’t enough to drive growth and brands including Fairlife and Darigold Fit have built their portfolios around protein as well as lactose-free, lower sugar and ultrafiltered milk claims.
Meanwhile, yogurt brands such as Oikos Pro, Oikos Triple Zero, Chobani Protein, Yoplait Protein, Light & Fit, and siggi’s, are innovating with higher protein content per pack while also incorporating reduced or no added sugar claims.
Global demand for high-protein dairy accelerates
The US may be the single largest market for high-protein dairy, but it isn’t alone in driving global growth.
High-protein dairy has become a defining trend across Europe, Australia and parts of Asia where manufacturers are investing heavily in innovation prioritise satiety, muscle health and healthy ageing, protein has become a universal platform for premiumisation rather than a niche sports nutrition claim.
The latest retail sales figures on high-protein dairy from the US highlight a fundamental shift in purchasing behaviour. Protein is no longer a peripheral claim or a feature reserved for specialist products: it has become one of the industry’s most important differentiators.
