What is whey protein?

The whey protein industry belongs to the production, distribution, and sales of those products that are whey-based proteins extracted from milk in a process of cheese making. Whey protein is an excellent source of complete protein that contains significant essential amino acid content. It finds its major application in sports nutrition, dietary supplements, infant formulas, functional foods and animal feed applications. This product is highly preferred by athletes as well as fitness-conscious consumers due to its quick digestibility and muscle recovery properties. The major forms of whey protein concentrate available in the market include isolate and hydrolysate; these forms differ from one another based on their protein content as well as degree of processing. Growing consciousness across different segments about the importance of protein consumption relative to health and wellness drives demand globally.

Proteins are now preferred with no additives, preservatives, or even allergens, and are made with the least amount of processing. A survey conducted by Ingredion in 2023 showed more than 65% of consumers from around the globe view clean-label products as an important factor for purchasing nutritional supplements. Manufacturers are now looking to cold-processed whey proteins, and organic or non-GMO certifications to meet this demand. An example of this was Glanbia Nutritionals and their “NaturPro” range, which features cold-filtered whey protein concentrates that are minimally processed to keep the natural bioactive compounds. Such products are extremely attractive in North America and Europe, which consists of more than 70% of the global clean-label whey market share, and demand does not ignore purity or quality.
• Functional and personalized nutrition solutions: The functional uses of whey protein are increasing as multi-layered personalized nutrition expands. Apart from sports whey protein is also utilized in meal substitutes, in weight control formulation devices, supplements for cognition and in other multi-functional products. As personalized nutrition continues to grow, nutrition recommendations based on one’s genetics, lifestyle, and other personalized attributes opens up more possibilities for whey protein. When looking over the data, the global personalized nutrition market is likely to grow up to USD 17.5 billion by 2030, exhibiting a 10-12% CAGR on the condition that protein enriched formulations are at the forefront.

Whey Protein Market Dynamics

Market Drivers

• Expanding applications of whey protein: Whey protein’s use spanning from exercise supplements to functional foods and beverages serves as a significant driver for growth in the sector. Its adaptability makes it possible for whey protein to be included in such items as protein bars, meal replacement shakes, baked goods, and even infant formulas. The functional foods sector is where protein enriched foods will thrive, as it is growing rapidly: from USD 140 billion in 2021, it will reach USD 275 billion in 2030, making it the fastest growing sector in the food industry, approximately 8-10% CAGR. The most dynamic is the Asia-Pacific region, specifically China and India, where augmented economic growth is leading to a growing upper-class tuned to health and nutrition. Primarily, Friesland Campina in these regions enabled consumer demand for convenient nutrition by launching whey protein-fortified dairy beverages. Moreover, there is a significant demand by e-commerce platforms for whey protein encompasses. Online sales have surged by 25% since 2020, allowing time-pressed buyers to access health products.
• Technological advancements and product innovation: New processing methods such as cold and microfiltration further increase protein purity and bioavailability while preserving important bioactive elements, allowing the native bioactive elements to meet the needs of consumers for clean-label and high-quality goods. Companies are shifting towards ultra-convenient formats of whey protein such as ready to drink shakes, flavored powders, and protein enriched snacks which fit into busy schedules. As an example, Hilmar Ingredients launched some whey protein isolates with improved taste and solubility which can greatly enhance their use in beverages and bakery goods. There is also an increasing trend of incorporating whey proteins with plant-based ingredients which diversifies foods for flexitarians and those looking for more sustainable foods. All of these are not only increase the applications of the products but also increase adoption by consumers of different ages and locations. Continuous innovations strengthen the competitive advantage of whey protein in the nutraceuticals market and are projected to support 7-9% CAGR through 2034.

Market Restraints

• Lactose intolerance and dairy allergies: Whey protein's production from milk means it has naturally occurring lactose, which is problematic for the growing demographic of lactose intolerant individuals—approximately 65% of the global population. This condition is associated with the bloating, cramps, and diarrhea and is a deterrent for many users of whey-based supplements. In addition, although less common, milk protein allergies are more serious, which limits the accessibility of whey protein products. These factors have motivated some consumers looking for non-dairy sources, affecting the sales of whey protein. For example, Glanbia Nutritionals developed lactose free whey protein isolates for the sensitive consumers in Europe. While there is a 10-20% prevalence of lactose intolerance in Europe, the segment is niche compared to the overall market. Simultaneously, the need to educate consumers and the lack of clear labeling overly complicates marketing, which slows adoption.
• The growing popularity of plant-based proteins: The plant protein market, which includes proteins derived from peas, rice, and soy, is expected to grow at a CAGR of 10%. This is driven by the increase in veganism, concern for the environment, and a shift toward more sustainable nutrition. In comparison with plant proteins, whey proteins are expected to grow at a slower rate. Internationally, the whey protein market is dominated by the traditional producers of whey protein. These critics often assume plant proteins are more sustainable and acceptable for people with dairy allergies. Nutrition brands such as Beyond Meat have started using rice and pea protein to mimic the amino acid profile of whey which finds widespread acceptance. There is still a challenge for traditional whey protein producers to keep pace with plant protein innovations which appeal to younger consumers turning vegan.

Market Challenges

• Price volatility of whey protein raw materials: Factors like feed costs, the weather, and the global supply and demand balance directly affect the dairy sector, which in turn impacts whey protein supply.  As the U.S. Department of Agriculture reported, average milk prices on the farm surged over 15% in 2023. This directly resulted in whey protein concentrate prices also climbing. The resulting cost variation ultimately increases retail pricing, which in turn drives away low cost-sensitive consumers and makes supply chain planning more difficult for manufacturers.
• Environmental sustainability issues linked to dairy farming: Due to greenhouse gas emissions, water usage, and land degradation, dairy production is under close watch from consumers and environmental groups. The FAO claims that the dairy sector emits approximately 4% of the global greenhouse gases. This contributes to the increasing concern and awareness of consumers that motivates the search for more sustainable and eco-friendly protein sources. Consequently, This trend is forcing manufacturers of whey protein to adopt and communicate more sustainable practices. These actions cut carbon emissions, and “go green” to protect brand loyalty while fighting more sustainable competition.  Growing concern for the environment will keep plant-based alternatives in demand. Ultimately, this will grow the market share of these plant protein alternatives while putting more whey manufacturers out of business if they don’t adapt. The trend of embracing plant-based alternatives is predicted to thrive, the eco-friendly impact will be more desirable.
