Find the signal behind persistent symptoms.
Bloating, irregularity, discomfort, fatigue, and other patterns can have a gut component. Testing reveals the bacterial ecosystem you cannot see directly.
At-home gut microbiome test
Your gut talks. We translate.
See what’s happening in your gut, how it may influence digestion, bloating, energy, mood and inflammation, and what to do next.

01 Why test your microbiome?
Your gut influences far more than digestion.
Your gut bacteria help break down food, produce compounds your body uses, interact with your immune system, and shape the environment behind digestion, inflammation, metabolism, energy, and mood.
See what disruption left behind.
Antibiotics, illness, stress, travel, and major diet changes can reshape your microbiome. Testing shows what remains, what expanded, and what may need support.
Replace generic advice with your data.
A probiotic, supplement, or food plan is only useful when it matches your starting point. Your microbiome shows which targets deserve attention.
Create a baseline you can improve.
Measure where you are now, act with intent, and retest to see which bacteria and microbial functions actually changed.
02 Why species-level insights matter
A genus is a category. A species is the answer.
A genus is like a last name: it groups related bacteria together. Species are the individual members—and members of the same genus can play very different roles inside the body.
If a test stops at the genus, it can blur the exact functions, health associations, and food responses that make the result useful.
The closer you get to the species, the closer you get to an insight you can actually use.

Streptococcus
One broad label
Fermented dairy and lactose digestion
Common oral commensal with probiotic potential
Strongly studied colorectal-cancer association
Same genus. Different functions. Different health associations. Different next steps.
03 From species to health
Specific species are connected to specific health outcomes.
Researchers repeatedly find individual species high, low, present, or absent alongside different health outcomes. Those links turn a list of bacteria into context: which microbes may support you, which may work against you, and which deserve attention first.
Faecalibacterium prausnitzii
A leading butyrate producer connected to gut-barrier integrity and lower inflammatory activity.
Akkermansia muciniphila
A mucus-layer specialist repeatedly linked with glucose regulation and metabolic health.
Mediterraneibacter gnavus
Often enriched in research on inflammatory bowel conditions and disrupted gut ecosystems.
Fusobacterium nucleatum
Widely studied for its links to gut inflammation, oral-gut migration, and colorectal cancer.
One species is a clue. Your full community is the story. The pattern across hundreds of bacteria reveals far more than any single organism can.

One result is a snapshot. Trends require repetition.
HelloTummy’s long-read 16S test is designed to show who your bacteria are at the species level and what their detected profile is computationally predicted to do. Regardless of the technology, repeated testing under similar collection conditions is more useful for following trends over time—and we price our test with that in mind.
