The global seaweed protein market size was estimated at USD 536 million in 2024 and is projected to reach USD 976.46 million by 2030, growing at a CAGR of 10.5% from 2025 to 2030. The growth of the seaweed protein market is primarily driven by rising health consciousness and the increasing demand for plant-based proteins.
In contrast, seaweed cultivation requires minimal land and freshwater resources and can even help improve marine ecosystems by absorbing excess nutrients. This makes seaweed protein a highly sustainable protein source, aligning with the growing consumer and industry focus on eco-friendly food production.
Technological advancements and ongoing research have further accelerated the market’s growth. Innovations in extraction and processing methods have improved seaweed protein production's yield, quality, and cost-effectiveness. Investments in marine biotechnology and research collaborations enable the development of new products and applications, making seaweed protein more accessible and appealing to a broader range of industries and consumers.
The versatility of seaweed protein has also contributed to its rising popularity. Beyond its use in food and beverages, seaweed protein is incorporated into cosmetics, personal care products, and animal feed. In the beauty industry, it is valued for its moisturizing and antioxidant properties, while in animal nutrition, it serves as a high-quality, plant-based alternative to conventional feed ingredients. This diversification across industries is broadening the market and attracting new consumer segments.
As more consumers adopt vegan and vegetarian lifestyles, they actively seek nutritious and sustainable alternatives to animal-based proteins. Seaweed protein, which is derived from varieties such as kelp, nori, and wakame, is rich in essential amino acids, vitamins, and minerals, making it an appealing choice for those focused on health and wellness. Additionally, environmental and sustainability concerns are also major factors fueling the market’s expansion. Traditional livestock farming is associated with significant greenhouse gas emissions, land degradation, and water pollution.
