The Global Fish Protein Isolates Market is experiencing significant growth, with a valuation of USD 765.5 million in 2024. The market is projected to expand at a CAGR of 7% from 2025 to 2034. This growth is being driven by several factors, including a growing awareness of the health benefits of fish-based proteins, increasing adoption of high-protein diets, and a rising demand for sustainable protein sources.

As consumers become more health-conscious, fish protein isolates have gained popularity due to their high nutritional value and rich amino acid profile, making them a go-to choice for fitness enthusiasts and health-focused individuals. Furthermore, the surge in plant-based and flexitarian diets is driving the need for alternative protein sources, which is positioning fish protein isolates as a highly adaptable and sought-after ingredient. These developments are further catalyzing the expansion of the market, which is anticipated to experience robust growth in the coming years.

The powdered segment of the market dominated in 2024, accounting for USD 656.9 million. It is expected to continue its upward trajectory, growing at a CAGR of 7.3% through 2034. Fish protein isolates derived from different fish species are highly valued for their essential amino acids and omega-3 fatty acids. The powder form offers excellent versatility, making it an essential ingredient in protein-rich food and beverage products. Its adaptability allows easy integration into a wide range of applications, from smoothies to snacks, ensuring its strong market position. This convenience, combined with its superior nutritional profile, continues to drive the growth of this segment.

The food industry also played a pivotal role in the market’s growth in 2024, generating USD 329.2 million. This segment is projected to grow at a CAGR of 7.8% from 2025 to 2034. The growing trend toward clean-label, nutritious, and sustainable diets has fueled the demand for fish protein isolates in food products. As consumers increasingly prioritize health-conscious ingredients, fish protein isolates are being incorporated into protein-enhanced products, including meat alternatives, protein bars, and other functional foods. These isolates offer not only superior nutritional benefits but also meet the dietary needs of a broad range of consumers, solidifying their place in the food sector.

In the United States, the fish protein isolates market reached USD 258.6 million in 2024 and is set to grow at a CAGR of 7.3% through 2034. This growth is driven by the rising consumer preference for clean-label, allergen-free ingredients in functional foods and beverages. The increasing awareness of sustainable protein sources is motivating manufacturers to make use of fish by-products, contributing to waste reduction and resource efficiency. Advances in extraction technologies are improving the purity of these isolates, allowing for broader applications in areas such as sports nutrition, dietary supplements, and infant nutrition, all of which are helping to increase market potential.
