Gut Microbiota Market Outlook:
Gut Microbiota Market size was valued at USD 860.4 million in 2025 and is set to exceed USD 4.66 billion by 2035, expanding at over 18.4% CAGR during the forecast period i.e., between 2026-2035. In the year 2026, the industry size of gut microbiota is evaluated at USD 1 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.
