Report Overview

The Global Seaweed Protein Market is expected to be worth around USD 1,753.6 Million by 2033, up from USD 564.6 Million in 2023, and grow at a CAGR of 12.0% from 2024 to 2033.
The seaweed protein market in Asia-Pacific is valued at USD 211.7 million, representing 37.5%.

Seaweed, encompassing red, green, and brown macroalgae, has garnered significant attention as a sustainable and nutrient-rich protein source. The protein content in seaweeds varies by species, with red seaweeds like Palmaria palmata (dulse) and Porphyra tenera (nori) containing approximately 35% and 47% protein by dry weight, respectively.

In India, the seaweed industry is expanding, with over 844 species reported in Indian waters and an estimated standing stock of about 58,715 tonnes (wet weight). Despite this diversity, the industry faces challenges, including underutilization of processing capacities due to raw material shortages.

To address these issues, initiatives like the dissemination of cultivation technologies for economically important seaweeds, such as Kappaphycus alvarezii, have been implemented to enhance production and support local communities.

Several factors drive the growth of the seaweed protein market. Seaweeds are rich in essential amino acids, vitamins, and minerals, making them a valuable addition to diets. For instance, consuming 5 grams of dried seaweed can contribute up to 4.5% of the reference nutrient intake for protein.

Additionally, seaweed-derived proteins and peptides exhibit antioxidant properties, which can delay lipid oxidation in foods and living systems, enhancing their appeal in the functional foods sector.

However, the industry must navigate challenges related to heavy metal content in seaweeds. The U.S. Food and Drug Administration (FDA) has analyzed seaweed for contaminants like cadmium and arsenic, emphasizing the need for monitoring to ensure consumer safety.

Looking ahead, the seaweed protein market presents substantial growth opportunities. The global commercial seaweed market is projected to reach USD 21.11 billion by 2023, with a compound annual growth rate of 8.4%. The food segment is expected to dominate this market, reflecting increasing consumer interest in plant-based and functional foods.
