With microbiome testing companies gaining more awareness over the last few years, it’s worth looking into some of the major players and discussing what microbiome testing is, and why it matters.
Companies in this budding area offer personalized solutions to gut problems via their specially-developed microbiome lab tests and supplements.
Viome, a health and wellness company based in Bellevue, Washington, is one of the most prominent in the industry, raising $86.5 million in venture capital last year and an additional $175 million after partnering with retail drugstore giant CVS to sell their testing kits.1
Researchers are beginning to attach more importance to the role gut bacteria plays in overall health, with studies suggesting that imbalances or deficiencies in certain organisms can potentially lead to bowel problems, a weakened immune system, skin issues, and even mental disorders.2
Furthermore, due to the increasing burden on the healthcare system, demand is rising to address gut problems.
According to a 2018 study in the American Journal of Gastroenterology, an estimated two out of every three Americans suffer from symptoms of gastrointestinal disorders.3
In addition, data shows that over 100 million ambulatory visits each year are due to GI diseases, with 14 million of those leading to hospital admissions.
Sadly, 236,000 people on average die each year to GI diseases.
To combat this worrisome reality, the NIH invested $150 million to research and understand the human microbiome.
Based on the findings from this project, biotech and pharma companies have begun developing microbiome tests to analyze gut flora, potentially allowing individuals to repair and replenish their gut-specific microbiome.4

Why is Gut Health Important?
To understand the importance of microbiome testing, we must first understand why gut health is so important.
First and foremost, a healthy gut ensures that food is properly broken down and nutrients are well-absorbed into the body.
However, what is less commonly known is that a significant portion of the immune system resides in the gut. A balanced microbiome, therefore, may help protect against pathogens and support immune responses.
Interestingly, gut health has also been found to be closely linked to mental health. The gut-brain axis is the communication network that links the gut and brain. Indeed, researchers have found strong correlations between gut problems and mental health conditions such as anxiety and depression.
Additionally, a healthy gut helps regulate inflammation, reducing the risk of chronic diseases like obesity, diabetes, and heart disease.
Gut bacteria also affects metabolism, influencing weight management and energy levels.
Finally, our gut plays an important role in detoxifying the body by processing and removing waste and other harmful substances.
What is Microbiome Testing?
Now that we have discussed the effect of the microbiome on one’s overall health, it becomes clear that understanding one’s unique gut environment can be particularly useful for addressing health problems.
Microbiome testing involves analyzing the ecosystem of microorganisms (bacteria, viruses, fungi, and other microbes) that reside in one’s gut, and as well as other mucosal areas like the mouth and skin.
Companies in this space claim that their tests can provide insights into the composition and activity of one’s microbiome, and can possibly detect deficiencies or imbalances that lead to health problems.5
How Microbiome Testing Works
The way microbiome testing works is simple. First, a sample – usually a stool sample, but sometimes from other mucosal areas – is collected from the individual.
That sample then undergoes DNA or RNA sequencing to identify the different microbes present and their relative abundance.
Advanced algorithms and bioinformatics tools analyze the sequencing data to provide a comprehensive profile of the microbiome.
Based on the analysis, personalized recommendations are provided, which may include dietary changes, probiotics, or lifestyle modifications to improve gut health.
Benefits of Microbiome Testing
Understanding one’s microbiome can help people tailor their diets to support beneficial bacteria and overall health.
For individuals with gastrointestinal issues or other health conditions, microbiome testing can lead to greater knowledge of the causes behind one’s symptoms, allowing one to recognize a and manage symptoms early before they manifest into a full-blown disease.
By improving gut health, individuals may also experience better digestion, mood, and increased energy levels.
Pitfalls of Microbiome Testing
While microbiome testing kits are the product of billions of dollars of research and investment, some scientists have been critical of the industry, with some even labeling it as snake oil.5
Much of the criticism points to the lack of regulations surrounding the industry, as well as its unverifiable claims.
“These companies claim they can determine whether a customer’s microbiome is healthy or in ‘dysbiosis’ — out of balance — and suggest that if so, it could be the reason for one or more health problems. Some of these companies may knowingly mislead consumers, while most appear to engage in questionable practices that are permitted by gaps in the current regulatory framework,” researchers wrote in a paper published in the journal Science.6
Another issue raised in this paper is the lack of consistency among test results, as well as the difficulty of drawing meaningful conclusions from the results.
While scientists agree that understanding the human microbiome could transform future healthcare and prevent disease, they believe more research is needed.
“[Microbiome tests] may be part of our clinical testing,” said Dr Vijaya Surampudi, a nutrition specialist at UCLA Health. “Possible uses might include assessing how a person responds to a particular medication or food. But we’re not there yet.”6
Companies such as Viome, Parallel Health, and Tiny Health acknowledged these concerns, but argued that their claims were supported by their proprietary data and methods.5
Nevertheless, companies and scientists in the space agree that there needs to be more consensus and regulations in place.
Tiny Health, which recently received $9 million in a Series A funding round, has made strides to obtain FDA approval for its infant tests through clinical studies.
Viome further hopes that the data they receive will fuel more research and generate more insight. Like genealogy company 23andMe, Viome is looking to capitalize on the data, possibly selling it to drug manufacturers.
