Quick answer: this gut health score is a free, 2-minute self-check built from 10 everyday signals researchers commonly link to a balanced digestive system and microbiome — things like bowel regularity, bloating, energy after meals, brain fog, fiber and fermented-food intake, antibiotic history, stress and sleep. It's not a diagnostic test — a lower score simply flags habits worth adjusting, while persistent or severe digestive symptoms are worth raising with a doctor. Answer the 10 questions above to see your score out of 100; no email is required to view it.
"Gut health" gets used loosely, but it points to something real and measurable: how well your digestive tract is doing at breaking down food, absorbing nutrients, and hosting a diverse, balanced community of bacteria. When that system is working well, digestion tends to be unremarkable — regular, comfortable, no drama. When it's out of balance, the signs usually show up as bloating, irregularity, fatigue that hits shortly after eating, or a foggy, hard-to-focus feeling that doesn't have an obvious cause. None of those symptoms are exclusive to gut issues, but persistent patterns across several of them are a reasonable prompt to look at diet, stress and sleep together, rather than in isolation.
What is the gut microbiome? It's the community of trillions of bacteria, fungi and other microbes living mainly in your large intestine. A diverse, well-balanced microbiome helps digest fiber, synthesize certain vitamins, train and regulate the immune system, and communicate with the brain via the gut-brain axis — the reason gut health is so often discussed alongside mood and stress, not just digestion. Diet, sleep, stress, antibiotic use and activity level all shape which bacteria thrive, which is why the questions above cover more than just what you eat.
What the 10 questions cover
The quiz groups its questions into three areas that, together, give a reasonable snapshot of gut health: digestive symptoms (bloating, bowel regularity, post-meal fatigue, brain fog), diet inputs that feed a healthy microbiome (vegetable and fermented-food intake), and risk factors known to disrupt it (recent antibiotic use, chronic stress, food intolerances, poor sleep). No single answer determines your result — it's the overall pattern across all 10 that produces your score.
What your score means
🌱
80–100 · Thriving
Regular digestion, minimal bloating, and habits — fiber, fermented foods, sleep, stress management — that actively support a diverse microbiome. Maintenance, not overhaul, is the goal here.
🙂
60–79 · Room to optimize
A solid baseline with a few clear gaps, often around fiber intake, stress or sleep. Small, targeted changes tend to produce a noticeable difference fairly quickly.
😕
40–59 · Needs attention
Multiple signals — frequent bloating, irregularity, fatigue after eating — point to a microbiome that is likely out of balance. A structured, few-weeks reset is usually more effective than one-off tweaks.
⚠️
Under 40 · Time for a reset
Several risk factors are stacking up at once. It usually responds well to focused changes, but if symptoms are severe or persistent, it is worth ruling out other causes with a doctor first.
Why gut health matters beyond digestion
A well-functioning gut does more than keep digestion comfortable — it plays a role in immune function, nutrient absorption, and even mood, since a large share of the body's serotonin is produced in gut tissue. That's part of why chronic digestive complaints so often show up alongside fatigue, low mood or difficulty focusing. If your score points to real room for improvement, our step-by-step guide to resetting your gut health and roundup of gut-health-supporting supplements are good next stops, and our gut health & microbiome course walks through the full picture in more depth. If the gut-brain connection is the part that resonates most, our gut-brain connection course focuses specifically on that link.

Key takeaways
- This is a self-check based on 10 everyday signals, not a medical or diagnostic test.
- Bloating, irregularity, post-meal fatigue and brain fog are common signs of gut imbalance.
- Diet, stress, sleep and antibiotic history all influence the gut microbiome, not just food alone.
- The quiz above takes about 2 minutes and needs no email to see your score.
