Casein protein is a slow-digesting, milk-derived protein that delivers a steady release of amino acids over several hours. It is rich in essential amino acids, particularly leucine, which supports muscle repair and growth. Casein protein is primarily used to aid muscle maintenance and recovery during extended periods without food, such as overnight, making it ideal as a bedtime supplement.
The main product types of casein protein include micellar casein, casein hydrolysate, and others. Micellar casein is a slow-digesting protein in milk that forms micelles, providing a sustained release of amino acids. Its functions include stabilizing, emulsifying, foaming, and more. Casein protein is distributed through channels such as online stores, supermarkets or hypermarkets, and specialty stores. It finds applications in nutritional supplements, food and beverages, agriculture or animal feed, cosmetics, pharmaceuticals, and others, serving end-users including athletes, bodybuilders, general consumers, and more.
Tariffs have affected the casein protein market by raising costs for milk-derived raw materials, protein concentrates, and supplement-grade processing equipment. Micellar casein and hydrolysate segments used in sports nutrition and dietary supplements are most impacted, especially in North America and Asia-Pacific where imports dominate. Online and specialty nutrition channels face pricing volatility. On the positive side, tariffs are driving regional dairy protein production and supplement manufacturing.

The casein protein market size has grown strongly in recent years. It will grow from $4.93 billion in 2025 to $5.33 billion in 2026 at a compound annual growth rate (CAGR) of 8.1%. The growth in the historic period can be attributed to fitness culture growth, bodybuilding nutrition, whey protein saturation, supplement retail expansion, protein intake awareness.
The casein protein market size is expected to see strong growth in the next few years. It will grow to $7.18 billion in 2030 at a compound annual growth rate (CAGR) of 7.7%. The growth in the forecast period can be attributed to sports nutrition demand, aging active population, premium protein supplements, clean ingredient sourcing, online supplement sales. Major trends in the forecast period include growing demand for nighttime protein supplements, increased use in sports nutrition, expansion of micellar casein products, growth of clean label protein powders, adoption in muscle recovery nutrition.
The rising popularity of nutritional supplements is expected to drive the growth of the casein protein market in the coming years. Nutritional supplements are orally consumed products containing nutrients such as vitamins, minerals, amino acids, or herbs, intended to complement the diet and support overall health. This growing popularity is fueled by increasing health awareness, as more individuals aim to prevent illness, strengthen immunity, and enhance overall well-being through proactive nutrition. Casein protein serves as a nutritional supplement that provides slow-digesting, sustained amino acid release, making it ideal for muscle recovery and maintenance. It offers prolonged nourishment, particularly during fasting periods, thereby improving the effectiveness of supplementation. For instance, in December 2024, according to the United Nations International Children's Emergency Fund (UNICEF), a US-based humanitarian aid organization, nearly 480 million vitamin A capsules were distributed to 71 countries in 2023, enabling over 320 million children to receive two doses of vitamin A supplementation-a 26% increase from previous years. Therefore, the rising popularity of nutritional supplements is boosting the growth of the casein protein market.
Major companies in the casein protein market are focusing on developing innovative offerings, such as plant-based casein products, to cater to the growing demand for sustainable and alternative protein sources. Plant-based casein refers to protein products designed to replicate the functional and nutritional properties of dairy casein while being entirely derived from plant sources. For instance, in May 2025, Pureture Co. Ltd., a US-based biotechnology company, launched Emulsifier-Free, a plant-based casein protein that closely mimics the texture and nutritional qualities of traditional dairy casein. This innovation eliminates the need for additives like emulsifiers or stabilizers, supporting clean-label products that appeal to health-conscious consumers. It delivers a complete amino acid profile with a PDCAAS score of 1.0, matching the nutritional value of dairy casein while enabling allergen-free and plant-based product formulations.
In July 2024, Leprino Foods Company, a US-based food manufacturer, partnered with Fooditive BV to develop innovative plant-based and sustainable food products. This collaboration aims to promote sustainability in the food industry by commercializing a non-animal casein protein as an alternative to traditional animal-derived casein. Fooditive BV, a Denmark-based food technology company, developed a vegan casein protein using precision fermentation.
