Gut Microbiota Market size was over USD 770.87 million in 2024 and is anticipated to cross USD 7.56 billion by 2037, growing at more than 19.2% CAGR during the forecast period i.e., between 2025-2037. In the year 2025, the industry size of gut microbiota is estimated at USD 1.02 billion.
The growth of the market can be attributed to the growing focus on the human immunity system post-COVID-19 as people with low immunity were most affected by the pandemic. According to the World Health Organization as of 23rd March 2023, there have been 761,071,826 confirmed cases of COVID-19 worldwide, which includes 6,879,677 deaths to date. Moreover, the increasing role of gut microbiota in immunity besides the rising research on how to improve gut flora is further expected to boost the market growth.
In addition to these, factors that are believed to fuel the market growth of gut microbiota include soaring investments, and collaboration between major key players to study & develop the human microbiome therapy to the next level. For instance, as per a new Bar-Ilan University study, gut microbes are anticipated to diagnose gestational diabetes as early as the first trimester of pregnancy which is months earlier than typically detected. The rising concern about gestational diabetes mellitus (GDM) worldwide which plagues around 10% of pregnant women across the globe is predicted to present the potential for market expansion over the projected period.
Growth Drivers
Growing Prevalence of Gastrointestinal (GI) Tract Diseases – gut microbiota being a vast and complex collection of microorganisms affects human health in many ways. They are essential in helping humans to absorb nutrients. Therefore, the rising prevalence of the GI tract amongst the global population owing to an increase in the consumption of unhealthy foods, and surging stress levels among middle age people worldwide are anticipated to propel the market growth. It is observed that in the United States, the estimated prevalence of irritable bowel syndrome is between 11% and 14% and this share is predicted to increase further in the upcoming years.
Increasing Ubiquity of Type 1 & Type 2 Diabetes - the alterations in the intestinal bacterial composition are known to be associated with the presence of chronic low-grade inflammation. This is a characteristic of insulin resistance and type 2 diabetes mellitus. The rising ubiquity of type 2 diabetes worldwide is anticipated to boost the market growth in the forecast period. As per research, over 37 million Americans are suffering from diabetes (nearly 1 in 10), and around 90-95% of them have type 2 diabetes.
Rising Health Spending – Recent expenditure data states that health spending worldwide has increased over the past 20 years, doubling in real terms to reach USD 8.5 trillion in 2019 and 9.8% of GDP, up from 8.5 percent in 2000. With the rising concern of low microbial diversity in the gut among children and middle age populations, the market is estimated to flourish over the forecast period.
Surging Prevalence of Diarrhea in Children – According to the World Health Organization report, diarrhea is listed as the second general cause of death in children under the age of 5, killing nearly 500 000 children under the age of 5 every year. Moreover, about 2 billion children worldwide suffer from diarrheal sickness every year.
As there are both, good and bad bacteria present in the gut, the entrance of harmful bacteria in the GI tract causes infection. Hence, the market is expected to grow at a substantial rate with the increasing research & spending to curb such infections that cause food poisoning and other GI diseases that result in diarrhea and vomiting among the populaces.

Application (Therapeutics, Diagnostics)
The global gut microbiota market is segmented and analyzed for demand and supply by application into therapeutics, and diagnostics. Out of the two types of gut microbiota, the segment is estimated to gain the largest market share of about 60% in the year 2037. The growth of the segment can be attributed to the increasing expenditure on biomedical, biopharmaceutical as well as biotechnology industries worldwide as well as increasing sales of biopharmaceuticals post-COVID -19. For instance, out of the total drug sales in 2021, biopharmaceuticals generated around 40% of global drug sales. Furthermore, the rising number of collaborations for R&D between market key players to better understand human gut health and develop apparent drug delivery systems to enhance the balance of gut microbiota besides the growing technological advancement in the therapeutics segment is further anticipated to boost the segment growth.
Disease (Autoimmune Disorder, Gastrointestinal Disorder, Infectious)
The global gut microbiota market is also segmented and analyzed for demand and supply by disease into autoimmune disorders, gastrointestinal disorders, infectious and others. Amongst these three segments, the infectious segment is expected to garner a significant share of around 45% in the year 2037. The segment growth is backed by the increasing prevalence of unspecified gastroenteritis as well as the growing number of suffering from patient diarrheal illnesses besides rising incident cases of acute gastrointestinal (GI) infections caused by Campylobacter, nontyphoidal Salmonella, Shigella, Escherichia coli (E. coli), or norovirus. For instance, a report stated that between the years 2010-2019, in the United States, the cases of unspecified gastroenteritis/diarrhea diagnoses accounted for over 98%. Moreover, nearly 2,241 cases of Campylobacter infections were diagnosed in the same period followed by Salmonella infections, Shigella, Escherichia coli (E. coli), or norovirus.

North American Market Forecast
North America industry is set to hold largest revenue share of 35% by 2037, The growth of the market can be attributed majorly to the rising concern about digestive illnesses such as gastroesophageal reflux disease (GERD) as well as other lifestyle disorders owing to the growing sedentary lifestyle, remote jobs, junk foods, and others. For instance, as per a study in 2022, nearly 20% of the U.S. population was affected by GERD or chronic acid reflux. Moreover, the rising spending on health care in the region is further expected to enhance the gut microbiota market in the region.
Europe Market Forecast
The European gut microbiota market is estimated to be the second largest, registering a share of about 25% by the end of 2037. The growth of the market can be attributed majorly to the rapidly rising geriatric population as well as the growing ubiquity of heart diseases and other chronic diseases coupled with the increasing research & development and clinical trials in the field of microbiome therapy in the region. It was found that over one-fifth or over 21% of the European Union population was aged 65 and over in 2022. Moreover, the increasing awareness of preventive healthcare in the region is further anticipated to propel regional market growth.
APAC Market Statistics
Further, the market in the Asia Pacific, amongst the market in all the other regions, is projected to hold a majority of the share by the end of 2037. The presence of a vast pool population as well as the growing prevalence of autoimmune diseases such as celiac diseases, diabetes, asthma, cancer, and others in the region coupled with the increasing prevalence of obesity and other lifestyle-related diseases. For instance, a study conducted in 2019, recruiting nearly 19,778 Chinese adolescents and young adults, showed that the prevalence of celiac disease autoimmunity reached nearly 2.19% in the country. Moreover, diabetes prevalence in Chinese adults is estimated to rise from 8% to around 9.5% among the age group of 20–79 years between 2020-2030.
Merck KGaA a leading science and technology company and leader in genome editing, collaborated with Washington University in St. Louis, Missouri, USA, for leading towards the optimization of nutritional supplements to restore a healthy gut microbial community (microbiome). This gut bacteria research would use Merck’s genome-editing technology and may lead to diagnostics, and treatment for malnourished children.
Metabiomics Corp., an early-stage molecular diagnostics company entered into a joint venture with Prescient Medicine Holdings, LLC, a company that operates in the Medical Devices industry to develop an innovative microbiome diagnostics platform.
