Gut microbiome tests are designed to explore the community of bacteria currently living in your digestive system. Because the gut microbiome plays a role in digestion, immune signalling, and gut comfort, some people choose to test as a way of better understanding what’s happening beneath the surface.
Why might you choose to have a gut microbiome test?
Common reasons people consider microbiome testing include:
Ongoing digestive discomfort or changes in bowel habits
Curiosity about how diet, stress, or lifestyle may be affecting gut health
Recovery after illness, travel, or antibiotic use
An interest in more personalised or preventative health approaches
While gut microbiome tests can't and don’t diagnose medical conditions, they can highlight broader microbial patterns and trends. For many people, this information becomes a useful starting point for making informed choices around friendly bacteria supplementation and lifestyle.
How should gut test results be understood?
Your test results should always be considered alongside how you feel, your diet, lifestyle, and recent medication or illness. Two people can have similar reports and feel very different. This is where qualified health practitioners, like our Optibac nutrition experts, come in as they have the training and skills to interpret results and see the wider picture.
Although different tests present results in different ways, most reports focus on similar themes, such as bacterial diversity, overall balance, and specific markers linked to digestion or the environment of the gut.
Results are best viewed as a big-picture snapshot, rather than something to analyse line by line. Individual markers rarely tell the full story on their own; overall trends and patterns are far more meaningful.
One of the most common results people see is lower microbial diversity. While this can sound concerning, it is often influenced by factors such as recent antibiotic use or stress. For many people, low microbial diversity can be supported through relatively simple, consistent changes over time. Adding in well researched friendly bacteria can help to support microbiome diversity. Every Day EXTRA is our advanced, multi-strain digestive supplement. This supplement contains 4 high-quality strains of friendly bacteria suited to both the small (Lactobacillus) and large (Bifidobacterium) intestines. Gut microbes love prebiotic fibre and polyphenol-rich foods, such as berries, apples, garlic and onions, so including these in your diet several times a week can boost diversity too.
Colourful vegetables & fruits are rich in polyphenols
It is also relatively common to see intestinal parasites, like Blastocystis, in your gut test results even if you aren't experiencing any symptoms as some parasites can be present in small amounts without causing issues. They are not necessarily a cause for concern. If you do wish to address intestinal parasites then Saccharomyces boulardii, an extensively researched friendly yeast, would be a good supplement choice.
Remember that microbiome results are not fixed. The gut environment is highly adaptable and responds well to ongoing habits, including eating a wide range of plant-based foods (think vegetables & fruits, beans & pulses, nuts & seeds) and taking a daily friendly bacteria supplement, rather than quick fixes.
What to do after your gut microbiome test
For many people, gut microbiome test results help guide practical next steps, which can include dietary adjustments and the considered use of well researched friendly bacteria supplements. Live cultures play a supportive role when chosen thoughtfully.
If you’re unsure how to interpret your results or which type of support may be most appropriate, our expert nutrition team can help you understand the findings and guide you in choosing an Optibac friendly bacteria supplement that complements your gut microbiome while fitting your individual needs.
