The global algal protein market was valued at USD 1015 million in 2025. The market is projected to grow from USD 1105 million in 2026 to USD 2185 million by 2034, exhibiting a compound annual growth rate of 8.9% during the forecast period. Contrive Datum Insights presents this information in its report titled "Algal Protein Market Size, Share & Industry Analysis, By Source (Spirulina, Chlorella, Other Algae), Product form (Powder, Tablets & Capsules, Liquid Extracts), Application (Dietary Supplements & Nutraceuticals, Food & Beverages, Animal Feed & Pet Food, Cosmetics & Personal Care), Cultivation method (Open Pond Systems, Closed Photobioreactor Systems), Distribution channel (Business-to-Business / Direct Sales, Retail & Pharmacy Stores, Online Retail), and Regional Forecast, 2026-2034".
Algal protein refers to protein derived from cultivated microalgae and macroalgae species, primarily spirulina and chlorella, marketed as protein-dense powders, tablets, capsules and liquid extracts. It is used by dietary supplement and nutraceutical brands, food and beverage manufacturers formulating plant-based and functional products, animal feed and aquafeed producers, and cosmetics and personal care formulators. Buyers range from bulk ingredient purchasers integrating algae protein into branded products to specialty retailers selling algae-based supplements directly to consumers.
Rising demand for plant-based and algae-derived protein sources
Rising demand for plant-based and algae-derived protein sources is the largest single contributor to the market's growth over the forecast period, and the study rates its impact high. Against a market growing at 8.9% a year, the source lines exposed to it move fastest: Chlorella compounds at 10.26%, taking its share of revenue from 34% to 38% and its value from USD 345.1 million to USD 830.3 million.
A more favourable outcome is possible. If assumes faster mainstream food and beverage adoption of algae protein alongside quicker photobioreactor capacity scale-up that lowers per-kilogram costs faster than the base case, 2034 revenue reaches USD 2447.2 million instead of the USD 2185 million the base case carries.
Against that, assumes slower regulatory approval of novel algae-derived food ingredients and a persistent cost premium versus soy and pea protein that keeps adoption confined mostly to the supplement channel. On that reading 2034 revenue stops at USD 1922.8 million. The weight of the problem sits in Spirulina: 48% of 2025 revenue growing at 7.84%, well under the market's 8.9%.
