A key growth driver is the strong shift toward science-backed, marine-derived proteins in dietary supplements, functional foods, and clinical nutrition. Global aquatic food production hit 185.4 million tonnes of aquatic animals in 2022, reflecting the central role of seafood in healthy diets and creating abundant by-products for high-value protein fractionation. Multiple clinical and preclinical studies show that fish protein hydrolysates deliver antihypertensive, antioxidant and anti-inflammatory peptides, supporting cardiovascular and metabolic health. For example, an 8-week randomized, double-blind trial in 144 adults with mild to moderate hypertension found that shrimp protein hydrolysate supplementation significantly reduced daytime ambulatory systolic blood pressure compared with placebo. These efficacy data, combined with growing consumer preference for natural, easily digestible proteins, are pushing manufacturers of sports nutrition, medical foods, and senior nutrition products to incorporate fish protein isolates into powders, ready-to-drink beverages and clinical formulations.
Another powerful driver is the global transition toward circular use of marine resources. The Food and Agriculture Organization (FAO) estimates that up to 35% of global fishery and aquaculture production has historically been lost or wasted each year, largely during processing and distribution. Fish frames, heads, skins, and viscera can contain protein levels exceeding 10-20%, and modern enzymatic hydrolysis processes enable their conversion into functional protein hydrolysates and isolates suitable for human nutrition and high-performance feed. The FAO’s Blue Transformation agenda calls for more efficient and sustainable aquatic food systems, including better utilization of by-products, which directly aligns with the business models of fish protein isolate producers. As aquaculture production alone reached about 94.4 million tonnes of aquatic animals in 2022, surpassing capture fisheries for the first time, the volume of raw materials available for valorization into high-purity proteins is expanding rapidly, structurally supporting market growth.
Fish protein hydrolysates and isolates often contain hydrophobic peptides that impart pronounced bitterness and marine odours, which can limit their inclusion levels in beverages and mainstream foods. Scientific reviews note that while enzymatic hydrolysis improves digestibility and bioactivity, it can also generate off-flavours that require additional purification or microencapsulation, raising processing complexity and cost. Enzymatic hydrolysis plants demand specialized reactors, separation equipment, and strict process control, creating significant capital expenditure particularly burdensome in regions with limited access to affordable finance. Furthermore, formulating clear beverages and highly soluble powders with fish-derived proteins is technically challenging due to solubility and stability issues, which can discourage brand owners from adopting fish protein isolates in high-visibility consumer products where flavour and mouthfeel are critical purchase drivers.
Fish protein isolates present compelling opportunities in clinical nutrition, geriatric care, and therapeutic foods. Studies in malnourished children show that salmon-derived protein hydrolysates can be safely administered at 3-6 g/day over several months without adverse effects, supporting normal growth, body mass index, and biochemical parameters. Recent work on texture-modified salmon products enriched with fish protein hydrolysate for dysphagia patients demonstrates that such formulations can increase protein density while maintaining safe swallowing characteristics, directly addressing the nutritional needs of older adults with swallowing disorders. In parallel, clinical trials with marine protein hydrolysates and shrimp-derived peptides have reported significant reductions in ambulatory blood pressure and favourable modulation of the renin-angiotensin system, highlighting their potential as adjuncts in cardiovascular risk management. As health systems in North America, Europe, and the Asia Pacific focus on home-based, high-protein medical nutrition solutions for ageing populations, demand for clinically substantiated fish protein isolates in oral nutritional supplements, tube-feeding formulas, and fortified purees is poised to accelerate.
Another high-impact opportunity lies in rapidly expanding functional beverage, sports nutrition, and specialty pet and aquafeed segments. Prototype electrolyte drinks and protein beverages formulated with tilapia skin-derived fish protein hydrolysate have shown high consumer acceptance, with more than 85% of panellists rating products as acceptable and overall liking scores approaching 90%, while delivering protein contents above 80% in the hydrolysate ingredient. Reviews of fish-derived bioactive peptides emphasize their antioxidant and antihypertensive activity, supporting positioning in performance recovery drinks, cardiovascular-health beverages, and “beauty-from-within” marine protein shots. On the animal side, fish protein hydrolysate-based concentrates are already used in hatchery feeds and premium pet food to improve growth performance and immunity, with commercial ranges of fish protein isolates containing 55-95% protein aimed at both human and companion animal nutrition. As functional beverages become the fastest-growing application segment and online channels expand the reach of niche sports and pet nutrition brands, suppliers of highly soluble, neutral-tasting fish protein isolates are well placed to capture outsized growth.
Powder is expected to remain the leading form segment in the fish protein isolate market by 2033. Dry powders offer superior shelf life, easier handling, lower transportation cost per unit of protein, and better compatibility with dry-blend manufacturing for bars, capsules, and powdered drink mixes. Industrial studies on fish protein hydrolysates consistently show that spray-dried powders can deliver protein contents above 80-90% with good solubility, enabling high inclusion levels in functional foods without excessive viscosity. Moreover, bio-based marine ingredients suppliers market premium fish protein isolates with around 95% protein and only 0.5% fat, specifically optimized for human nutrition applications such as ready-to-mix supplements, bakery fortification, and high-protein snacks. In contrast, liquid formats are more constrained by cold-chain requirements and microbial stability, making them better suited to intermediate concentrates or ready-to-drink beverages rather than broad B2B distribution.
Within applications, functional foods account for a leading share of fish protein isolate demand, representing about 39% of the market in 2025. This dominance reflects the strong uptake of marine proteins in high-protein bakery items, cereals, nutrition bars and fortified snacks positioned around muscle maintenance, satiety and metabolic health. Scientific reviews indicate that fish-derived bioactive peptides provide antioxidant, antihypertensive and anti-inflammatory benefits, making them ideal ingredients for health-positioned functional foods that go beyond basic nutrition. At the same time, major food systems reports from the Organisation for Economic Co-operation and Development (OECD) and FAO project steady increases in global fish and seafood consumption per capita over the coming decade, reinforcing consumer familiarity with marine-derived ingredients in everyday diets. As manufacturers reformulate to reduce sugar and saturated fat while maintaining palatability and protein density, fish protein isolates offer a label-friendly way to boost nutritional value in cereals, baked goods, and savoury products.
Supermarkets and hypermarkets are expected to remain the leading distribution channel for finished products containing fish protein isolates, especially in developed markets where consumers purchase marine-based supplements, functional snacks, and ready-to-drink beverages alongside routine groceries. High footfall, established cold-chain infrastructure, and expanding health-and-wellness aisles in large-format retail stores support strong on-shelf visibility for marine protein products. However, online channels are growing fastest, driven by rapid uptake of e-commerce for dietary supplements, sports nutrition and specialty pet foods. The rise of subscription models for high-protein powders, personalized nutrition packs, and veterinary-recommended pet diets creates natural pull for fish protein isolate-based formulations that emphasize digestibility, hypoallergenicity and sustainability. As digital-native brands leverage detailed storytelling around traceable fisheries and upcycled by-products, online platforms are becoming an increasingly important route to market for innovative fish protein isolate offerings.
