The global beta-glucan market was valued at USD 677.23 million in 2024 and is estimated at USD 731.27 million in 2025, the start of the forecast period. Polaris Market Research projects the market will reach USD 1,483.88 million by 2034, growing at a CAGR of 8.20% during the forecast period 2025–2034. The growing emphasis on immune-boosting dietary supplements is described as a primary growth catalyst, while use across multiple industries is driving significant expansion.

Functional Profile: Fiber Content and Gut Health Impact

Beta-glucan is a polysaccharide composed of glucose monomers connected by beta-glycosidic linkages. It is recognized as a dietary fiber with a significant impact on the gut microbiota. According to the report, beta-glucan interacts with gut microbes in a way that triggers positive responses, leading to benefits that include immune enhancement, regulation of serum cholesterol, management of insulin levels, reduction of obesity, and improvements in cognitive disorders.

Immune Support Drives Supplement Demand

An aging population and a growing emphasis on preventive healthcare are fueling demand for beta-glucan products. Consumers are turning to dietary supplements and fortified beverages to support their immune systems and promote longevity, which keeps immune-boosting dietary supplements at the center of commercial interest. Advancements in research and technology have also produced innovative formulations and delivery systems, expanding applications across pharmaceuticals, food and beverage, cosmetics, and animal nutrition.

Yeast Leads the Source Segment

By source, the market is segmented into yeast, cereal and grains (barley, oats, and others), mushroom, and others. Yeast-based beta-glucan garnered the largest share in 2024. It is favored for its skin-calming advantages, and the report notes that, unlike beta-glucan from barley or oats, the yeast-derived form is highly valued for its purity and effectiveness. Increased funding for clinical studies is further strengthening the market.

The report also cites the National Cancer Institute, which notes that a supplement containing beta-glucan from yeast may offer anti-inflammatory, antioxidant, and immune-boosting benefits and can activate the immune system. For B2B buyers, yeast-based beta-glucan is therefore a leading focus for ingredient sourcing, with purity tiers in the report ranging from 10%–20% to above 50%.

Soluble Format Gains Formulation Traction

Soluble beta-glucan dominates the market by functionality, primarily because of its ability to boost the immune system, and the segment is expected to witness the highest growth during the forecast period. It is easily added to foods, drinks, and supplements. Product improvements, marketing tactics, and educational efforts that address consumer preferences are driving growth, and companies offering tailored solutions gain a competitive edge.

In July 2023, Beneo launched Orafti β-Fit, which dissolves readily in water. Companies are also investing in clinical trials with human participants to demonstrate health benefits and to secure official approval for health claims.

Regional Outlook and Key Players

North America was the largest market in 2024. The report attributes the region’s dominance to the wide use of beta-glucan in different products and their related health advantages. In food and beverages, it is used as a thickening agent, fat substitute, dietary fiber, and cholesterol-lowering agent. In the U.S., awareness of calorie intake is steering consumers toward lower-calorie, lower-fat foods, and the report cites CDC data showing the adult obesity rate rose to 42.4% in 2020–2021.

Asia Pacific is expected to see significant growth, supported by an expanding dietary supplement sector and consumers seeking natural ways to boost immunity. The report notes that oats are gaining popularity as a breakfast option in India, alongside rising disposable income and a growing middle class.

Major players in the beta-glucan market include Alltech, Angel Yeast Co. Ltd, Associated British Foods Plc, Bigrigin, Ceapro, Inc., dsm-Firmenich, Garuda International Inc., Kemin Industries, Kerry Group plc, Lallemand, Leiber, Lesaffre, Merck, NutriScience Innovations, LLC, and Tate & Lyle PLC.

Strategic Takeaway for B2B Stakeholders

As the market advances from USD 731.27 million in 2025 to USD 1,483.88 million by 2034, suppliers that prioritize purity, soluble formats, and clinically supported immune benefits are positioned to serve the beta-glucan market’s documented demand drivers.
