Casein Protein Global Market Report 2025

The casein protein market size has grown strongly in recent years. It will grow from $4.56 billion in 2024 to $4.93 billion in 2025 at a compound annual growth rate (CAGR) of 8.2%. The growth during the historic period can be attributed to the increasing popularity of high-protein diets, expanded use in clinical nutrition, growth in sports nutrition applications, greater adoption in functional foods, and rising demand from the infant nutrition sector.

The casein protein market size is expected to see strong growth in the next few years. It will grow to $6.67 billion in 2029 at a compound annual growth rate (CAGR) of 7.9%. The growth expected during the forecast period is driven by the rising vegan and vegetarian population, increasing demand for slow-digesting proteins, expanding applications in cosmetic formulations, growing adoption of protein-rich foods, and a health-conscious consumer base. Key trends in this period include advancements in protein extraction technologies for casein-based supplements, the emergence of clean-label protein products, innovations in ready-to-drink protein beverages, and the development of sustainable dairy farming practices.

The increasing popularity of nutritional supplements is expected to drive the growth of the casein protein market moving forward. Nutritional supplements are oral products containing nutrients like vitamins, minerals, amino acids, or herbs designed to complement the diet and promote overall health. This growing popularity is fueled by heightened health awareness, with more people seeking to prevent illness, boost immunity, and enhance well-being through proactive nutrition. Casein protein serves as a nutritional supplement that provides a slow, sustained release of amino acids, making it ideal for muscle recovery and maintenance. It offers prolonged nourishment, especially during fasting periods, thereby enhancing the effectiveness of supplements. For example, in December 2024, the United Nations International Children's Emergency Fund (UNICEF), a US-based humanitarian organization, reported delivering nearly 480 million vitamin A capsules to 71 countries in 2023, aiding over 320 million children in receiving two doses of vitamin A supplementation - a 26% increase from the 252 million children reached in 2021. Thus, the rising popularity of nutritional supplements is fueling the growth of the casein protein market.

Leading companies in the casein protein market are concentrating on creating innovative products, such as plant-based casein alternatives, to address the rising consumer interest in sustainable and alternative protein options. Plant-based casein refers to protein products that replicate the functional and nutritional characteristics of dairy casein but are entirely sourced from plants rather than milk. For example, in May 2025, Pureture Co. Ltd., a biotechnology company based in the US, introduced an emulsifier-free, plant-based casein protein engineered to closely resemble the texture and nutritional profile of traditional dairy casein. This innovation eliminates the need for additives like emulsifiers or stabilizers, offering a cleaner label that appeals to health-conscious buyers. It also provides a complete amino acid profile with a PDCAAS score of 1.0, matching the nutritional benefits of dairy casein while enabling allergen-free and clean-label product development.

In July 2024, Leprino Foods Company, a food manufacturing firm based in the US, formed a partnership with Fooditive BV to create innovative plant-based and sustainable food products. The goal of this collaboration is to promote sustainability in the food sector by bringing to market an environmentally friendly, non-animal casein protein as a substitute for conventional animal-based casein. Fooditive BV, a food technology company headquartered in Denmark, developed a vegan casein protein through the use of precision fermentation.

Casein protein is a slow-digesting protein derived from milk that delivers a steady release of amino acids over several hours. It is rich in essential amino acids, especially leucine, which supports muscle repair and growth. Casein protein’s primary role is to aid muscle maintenance and recovery during extended periods without food, such as overnight, making it an ideal supplement before bedtime.

The main types of casein protein include micellar casein, casein hydrolysate, and others. Micellar casein is a slow-digesting protein naturally found in milk that forms micelles, allowing a sustained release of amino acids. Its functions include stabilizing, emulsifying, foaming, and more. Micellar casein products are distributed through various channels such as online stores, supermarkets or hypermarkets, and specialty stores. These products find applications in nutritional supplements, food and beverages, agriculture or animal feed, cosmetics, pharmaceuticals, and other sectors, serving end users like athletes, bodybuilders, and general consumers.
