Your microbiome is personal.
The mix and abundance of bacteria in your gut can differ substantially from someone else’s. General advice cannot show what is actually present in yours.

Why test your gut?
Your gut bacteria do more than help digest food.
Your gut is home to a complex bacterial ecosystem. These organisms help break down food, produce compounds that interact with your gut lining, and are studied for their relationships with immune and metabolic health.
A microbiome test is a snapshot, not a diagnosis. Its value is giving you a measured starting point instead of leaving you to guess.
It can change over time.
Diet, medications, age, illness, and lifestyle can all influence your gut community. Testing gives you a baseline you can revisit.
Results make the next step more specific.
See which bacteria were detected, how their levels compare, and which evidence-supported foods may help target the bacteria in your results.
Why HelloTummy?
Depth & Accuracy
Every sample is analyzed using a minimum of 20,000 full-length 16S reads, supporting the detection of lower-abundance bacteria within our validated reporting range. Our workflow has been evaluated using reference materials of known composition for analytical accuracy, precision, sensitivity, specificity, and sample stability. Positive and negative controls are included in every sequencing run to monitor ongoing performance.
Price & Access
Every test includes comprehensive species-level analysis for $100 — a fraction of the cost of other comprehensive species-level solutions.
Collection & Convenience
Every kit includes everything needed to collect at home in under five minutes, plus prepaid return shipping.
Insights & Action
Every report includes ranked food recommendations, plus supplement and lifestyle options where evidence supports them.
What you'll learn
- Your gut diversity score.
The more bacterial species we find, the greater the chance that you have a healthy gut ecosystem and a resilient immune system.
- Bacteria associated with inflammation and metabolic health.
See whether bacteria researchers study in connection with these health processes are unusually high or low in your gut.
- Your gut's potential to make helpful compounds.
Some gut bacteria help produce compounds that support digestion and the gut lining. See whether your microbiome may have that potential.
- What to eat and what to do next.
Get personalized food suggestions and evidence-supported next steps based on the bacteria detected in your sample.
How we turn your microbiome into food recommendations.
We identify which bacterial species are in your gut, review what those bacteria are associated with in the scientific literature, and rank foods by the evidence most likely to support the best overall outcome for your microbiome.
- 1 · Identify who is in your gut.Your sample is analyzed at the species level so we can see which bacteria stand out.
- 2 · Understand what those bacteria may do.We classify beneficial, neutral, potentially harmful, and harmful patterns using evidence drawn from 4,500+ research papers.
- 3 · Rank foods by likely net impact.Foods move up the list when evidence suggests they may support more beneficial species and reduce less helpful ones.
