Algae Protein Market Summary
The algae protein market reached an estimated USD 218.70 million in 2025 and is projected to grow from USD 235.80 million in 2026 to USD 449.52 million by 2035, registering a CAGR of 7.82% during the forecast period. Two catalysts are accelerating this trajectory: the US FDA's landmark endorsement of Galdieria extract blue as a permitted food color in June 2025 [1], and Europe's approval of more than 20 algae species for food and feed use during 2024 [2]. These regulatory clearances have unlocked application categories — from functional beverages to pet nutrition — that were previously off-limits for algae-derived ingredients.
Closed photobioreactor technology and sophisticated strain engineering are replacing open-pond cultivation in manufacturing, offering better protein yields with lower contamination hazards. Brevel’s investment in a 27,000 ft2 automated production facility in Israel, to be commissioned in early 2025, is a symptom of the industry’s move towards industrial-scale production [3]. Venture financing continues to flow into fermentation-enabled microalgae systems, promising cost parity with soy isolates by 2030, with investment in sustainable algal protein production accelerating.
North America is the leading region in the algal protein market, with a share of approximately 31% of the global revenue due to strong demand for supplements and favorable regulations. The Asia Pacific region is the fastest expanding region, with an expected CAGR of 8.92% through 2035, owing to the increasing demand for spirulina protein food ingredients in China, India and Southeast Asia. Europe is the second-largest region with a share of ~26% of the algal protein market, supported by the EU’s Novel Food framework and consumer demand for the chlorella algae protein nutrition products. The next decade will decide whether farmers can grow sustainably enough to deliver the protein diversification objectives of the food sector.
