Lactulose Market Size & Trends

The global lactulose market size was estimated at USD 506.0 million in 2024 and is expected to expand at a CAGR of 6.4% from 2025 to 2030. The lactulose market is growing due to rising demand for digestive health solutions and increasing cases of constipation and liver-related issues. 

Its role as a safe and effective treatment, especially for laxative and hepatic uses, supports this trend. Growing awareness about gut health and the benefits of prebiotics also adds to its demand. As people seek better health management, lactulose continues to see steady use in both medical and nutritional areas.

The increasing awareness of gut health and its impact on overall well-being has driven the demand for prebiotic ingredients like lactulose. As a non-digestible sugar, lactulose reaches the colon intact, where it serves as food for beneficial gut bacteria, such as bifidobacteria and lactobacilli. With the rise in digestive disorders like irritable bowel syndrome (IBS), bloating, and constipation, consumers are actively seeking functional foods and supplements that support gut microbiota balance.

Companies have responded by incorporating prebiotic ingredients into their products, including fermented dairy, functional beverages, and dietary supplements. For instance, lactulose has been added to probiotic yogurt formulations in Japan to enhance the effectiveness of live cultures, leading to better digestion and nutrient absorption. The global functional food market, valued at over USD 200 billion, is expanding rapidly due to the growing demand for natural solutions to improve gut health, making lactulose an attractive ingredient for manufacturers.

Lactulose plays a critical role in the treatment of hepatic encephalopathy (HE), a severe neurological condition caused by liver failure, where toxins like ammonia accumulate in the blood and affect brain function. Patients with cirrhosis, a major cause of HE, rely on lactulose to reduce ammonia levels by promoting its excretion through frequent bowel movements. The World Journal of Hepatology highlights lactulose as a first-line treatment for HE, often prescribed alongside antibiotics like rifaximin. For example, in the United States, where over 4.5 million adults suffer from chronic liver disease, hospitals frequently administer lactulose to prevent HE-related complications, such as confusion and coma.

The lactulose market is fragmented, with several global and regional players competing. Dominated by pharmaceutical and nutraceutical sectors, the market sees steady demand growth, driven by rising gastrointestinal disorders and increased awareness of gut health and prebiotic benefit.

Market Concentration & Characteristics

The market is fragmented, with global players such as Abbott, Fresenius, Morinaga Milk Industry Co., Ltd., Illovo, and Daiichi Sankyo holding significant shares due to strong distribution networks and brand trust.

Function Insights

The laxative segment dominated the market and accounted for the largest revenue share of 69.8% in 2024. This dominance is due to its long-standing and widespread use in treating constipation, especially in chronic and age-related cases. Lactulose is a non-absorbable sugar that draws water into the colon, softening stools and stimulating bowel movements. It is preferred over harsher laxatives because of its gentle action and safety, even for infants, pregnant women, and the elderly.

The sweetening agents segment is expected to grow fastest with a CAGR of 7.3% during the forecast period. Although this is a relatively small segment, it plays a specific and valuable role in health-focused food and beverage applications. Lactulose is a low-calorie sweetener with prebiotic properties, making it attractive for functional foods, diabetic-friendly products, and infant nutrition. It provides mild sweetness while promoting gut health by stimulating the growth of beneficial bacteria like Bifidobacteria in the colon.

Applications Insights

The pharmaceuticals segment dominated the market and accounted for the largest revenue share of 77.6% in 2024. This segment is primarily driven by the two major therapeutic uses of lactulose: as a laxative and in the treatment of hepatic encephalopathy (HE). Lactulose’s role as a laxative is well-established, widely prescribed, and available over-the-counter for treating chronic constipation, particularly in the elderly, pregnant women, and children due to its gentle, non-irritating mechanism. Its effectiveness, safety profile, and ability to restore healthy bowel movements have made it a staple in both home and hospital settings.
