Seaweed Protein Market Outlook:
According to the research report, the global seaweed protein market was valued at USD 481.82 million in 2022 and is expected to reach USD 1,407.41 million by 2032, to grow at a CAGR of 11.3% during the forecast period.
Market Overview
Seaweed protein, extracted primarily from red and green macroalgae such as Ulva, Porphyra, and Gracilaria, is gaining momentum as a marine superfood. It is valued for being a complete protein source, rich in essential amino acids, vitamins, minerals, and antioxidants. Moreover, its cultivation does not require land, fertilizers, or fresh water, making it an eco-friendly crop for the future.
As global food systems face mounting pressure from climate change, overfishing, and land degradation, seaweed farming presents a low-impact, high-yield solution. With uses ranging from human nutrition to animal feed and even bioplastics, the commercial potential of seaweed protein is expansive.
The shift in consumer preferences toward natural, minimally processed, and sustainable food ingredients has created a fertile market for seaweed protein as a next-generation plant-based protein.
