Seaweed Extracts Global Market Report 2025

The seaweed extracts market size has grown strongly in recent years. It will grow from $2.44 billion in 2024 to $2.58 billion in 2025 at a compound annual growth rate (CAGR) of 5.9%. The growth in the historic period can be attributed to increased demand for natural and organic products, increased awareness of the health benefits of seaweed, increased investment in marine biotechnology, increased use in food and beverages, and increased focus on functional foods.

The seaweed extracts market size is expected to see strong growth in the next few years. It will grow to " $3.29 billion in 2029 at a compound annual growth rate (CAGR) of 6.2%. The growth in the forecast period can be attributed to growing demand for sustainable and eco-friendly ingredients, rising adoption of seaweed-based products in cosmetics and personal care, rising trend towards plant-based diets, growing interest in plant-based nutritional supplements, and rising demand for biofuels. Major trends in the forecast period include integration with biotechnology, integration of sustainable practices, development of new extraction technologies, innovation in product formulations, and innovation in seaweed cultivation.

The forecast of 6.2% growth over the next five years reflects a modest reduction of 0.2% from the previous estimate for this market.This reduction is primarily due to the impact of tariffs between the US and other countries. This is likely to directly affect the US by limiting supply from South Korea and the Philippines, increasing costs for food thickeners and cosmetic additives.The effect will also be felt more widely due to reciprocal tariffs and the negative effect on the global economy and trade due to increased trade tensions and restrictions.

The increasing demand for biofuels is expected to drive the growth of the seaweed extracts market. Biofuels are renewable energy sources derived from organic materials such as plants, algae, or animal waste, serving as environmentally friendly alternatives to fossil fuels. The rising demand for biofuels is fueled by government policies mandating the use of renewable fuels to reduce greenhouse gas emissions, along with technological advancements that have improved production efficiency and sustainability. Seaweed extracts contribute to biofuel production by offering a sustainable, high-yield feedstock rich in carbohydrates, which can be efficiently converted into bioethanol and biogas, supporting the renewable energy sector. For example, in May 2022, The International Energy Agency (IEA), a France-based intergovernmental organization, projected that biofuel demand would increase by 38 billion liters between 2023 and 2028, nearly 30% higher than the previous five years. By 2028, biofuel demand is expected to grow by 23%, reaching 200 billion liters. Consequently, the rising demand for biofuels is driving the expansion of the seaweed extracts market.

Leading companies in the seaweed extracts market are focusing on innovative plant-based solutions to meet the increasing demand for sustainable and eco-friendly agricultural inputs. Plant-based solutions utilize natural ingredients derived from plants, offering sustainable alternatives to synthetic or animal-based components across industries such as agriculture, cosmetics, and food. For instance, in June 2023, Cascadia Seaweed Corporation, a Canada-based manufacturer of seaweed-derived products, partnered with ReFeed Ltd., a Canada-based nutrient upcycling company, to launch its first seaweed-based biostimulant. This biostimulant, enriched with bioactive compounds from sustainably farmed seaweed, enhances plant growth, improves soil health, and boosts nutrient uptake. Its key benefit lies in reducing dependence on synthetic fertilizers, promoting environmentally responsible farming practices.

In March 2023, J. Rettenmaier & Söhne Group, a Germany-based company specializing in fiber and hydrocolloid products, acquired Algaia SA for an undisclosed amount. This acquisition aims to expand JRS Group’s portfolio in sustainable, algae-based solutions and strengthen its presence in the global market for natural, renewable ingredients. Algaia SA, a France-based company, specializes in producing seaweed extracts and hydrocolloids.

Seaweed extracts are bioactive compounds obtained from different species of seaweed through processes such as solvent extraction, hydrolysis, or fermentation. These extracts are rich in essential nutrients, including polysaccharides, proteins, vitamins, minerals, and antioxidants. They are widely used in agriculture as biostimulants to promote plant growth, in the food and beverage industry as natural additives, and in cosmetics for their skin-nourishing benefits.

The primary types of seaweed extracts include red, brown, and green. Red seaweed, known for its distinctive reddish hue, is utilized across various industries such as food, cosmetics, and pharmaceuticals. Seaweed extracts are available in multiple forms, including liquid, powder, and flakes, and are applied in sectors such as food and beverages, agriculture, pharmaceuticals, and other specialized applications.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

The rapid implementation of U.S. tariffs and the resulting trade tensions in spring 2025 are having a notable impact on the food and beverage sector. Rising costs for imported ingredients such as olive oil, cheese, and tropical fruits are pressuring food manufacturers to either reformulate their products or absorb reduced profit margins. Beverage producers are similarly affected, with tariffs on aluminum cans driving up packaging costs. Meanwhile, retaliatory tariffs on U.S. agricultural exports like soybeans and pork are disrupting farm-to-processor supply chains. In response, companies are adjusting recipes, increasing local sourcing, and using commodity hedging strategies to manage price volatility.
