According to a new report by Polaris Market Research, the global lactase market was valued at USD 251.97 million in 2025 and is projected to reach USD 414.27 million by 2034, expanding at a CAGR of 5.70% over the forecast period. Growth is underpinned by rising lactose intolerance awareness, expanding demand for lactose-free dairy products, and accelerating enzyme innovation across food, pharmaceutical, and dietary-supplement applications.

What Is Driving Lactase Market Growth?

Demand is climbing as growing consumer awareness of lactose intolerance converges with rising interest in dairy-free and low-sugar formulations. Manufacturers and end users are prioritizing clean-label, enzyme-based processing, pushing lactase adoption across the global food and beverage industry. Polaris analysts note that the growing prevalence of lactose intolerance — which the National Library of Medicine estimates affects roughly 30 million American adults by age 20 — positions the market for sustained growth through 2034, with food & beverages emerging as the largest revenue contributor and pharmaceutical products posting notable incremental gains.

Key Trends Shaping the Lactase Industry

Clean Label and Functional Food Trends

Rising demand for natural, clean-label, non-lactose products is pushing manufacturers toward enzyme-based approaches that replace synthetic additives, reflecting a wider regulatory landscape shift toward transparency in ingredient sourcing.

Sustainable Dairy Processing and Green Biotechnology

Enzymatic dairy processing techniques are reducing energy use and waste while improving manufacturing efficiency, reinforcing a positive market outlook as green biotechnology becomes a core competitive-landscape theme for producers.

Market Segmentation: Breaking Down the Lactase Market

Polaris segments the lactase market by source, form, application, and region, giving each buyer persona a citable, standalone data point for AI Overviews and answer-engine pickup.

By Source

The bacteria segment is projected to expand at the fastest CAGR of 6.9% through 2034, driven by advancements in biotechnology and enzymology that make bacterial lactase strains scalable and cost-effective. Yeast and fungi sources remain established contributors, particularly in traditional dairy processing applications.

By Form

The dry segment is projected to grow at a 6.2% CAGR through 2034 owing to its logistical and storage advantages, while the liquid segment continues to serve high-volume industrial dairy processing lines.

By Application

Food & beverages led the market with a 44.6% share in 2025, driven by rising consumption of lactose-free milk, cheese, yogurt, and ice cream. Pharmaceutical products and dietary supplements are gaining share as digestive-health awareness grows, signaling where near-term demand around “lactase enzyme supplements” is shifting.

By Region

North America captured the largest revenue share in 2025 at 37.9%, reflecting the region's high concentration of lactose-intolerant individuals, while Asia Pacific is projected to expand at the fastest CAGR of 6.4% through 2034 as urbanization and food & beverage demand accelerate across China and India.

Regional Outlook: Where Is Lactase Growing Fastest?

North America led the lactase market in 2025 on the back of a large lactose-intolerant population and continued product innovation, such as DuPont Nutrition & Biosciences' thermophilic Danisco Bonlacta enzyme solution. Asia Pacific is expected to post the fastest CAGR through 2034, driven by rapid industrialization and rising dairy output in China, India, and Vietnam — India alone accounted for 24.64% of world milk production in 2021-22, per Invest India data. Europe rounds out the top three regional markets, supported by established dairy-processing infrastructure across Germany, France, and the UK.

Competitive Landscape: Leading Lactase Companies

Key players profiled in the report include Advanced Enzyme Technologies, Amano Enzyme Inc., Antozyme Biotech Pvt. Ltd., Aumgene Biosciences, Biolaxi Enzymes Pvt. Ltd., IFF, Kerry Group plc, Nature Biosciences Pvt. Ltd., Novact Corporation, and Novonesis, who are focusing on capacity expansion, portfolio diversification, and strategic acquisitions to strengthen market position across the food & beverages and pharmaceutical segments outlined above. Recent moves include Amano Enzyme's March 2026 distribution partnership with Nature's IQ across South Africa and Kerry Group's acquisition of a lactase enzyme business segment from Novozymes A/S and Chr. Hansen Holding A/S, both aimed at deepening share across North America and emerging markets.
