Market Overview

Casein is a protein made up of calcium, carbohydrate, amino acids, and other nutrients that the body requires. It is derived from various milk sources: cow, buffalo, sheep, goat, and yak. Casein does not have a smell or taste. It provides all the necessary amino acids and promotes the development of muscle, hunger scripts, an increase in metabolic rates, recovery of muscle mass, and maintenance of lean muscle in the body. Additionally, it is also used as an additive for recovery and prevention of muscle fatigue. Casein has high utilization rates in cosmetics, Food and Beverage (F&B), and pharmaceutical industries. Casein is utilized in a range of industries in Japan, including food and beverages, nutrition and health supplements, pharmaceuticals, and cosmetics. Steady market growth in Japan is being driven by demand for high-protein, functional, and clean-label products. Moreover, the extensive use of products in the pharmaceutical sector to create drugs for fatigue, stress, anxiety, and cancer prevention is another significant factor driving growth.
