Do you need a gut test, a probiotic, or neither?

What at-home gut tests can and can't tell you
Most at-home kits sequence the bacteria in one stool sample. That gives you a snapshot of which microbes were there that day, and some kits turn it into food and supplement suggestions. Useful for curiosity and motivation, but:
- They can't diagnose IBS, SIBO, celiac disease, IBD or food allergies.
- There's no agreed “healthy” microbiome yet, so scores are each company's own.
- Your microbiome shifts with what you eat, so one result isn't the whole story.
How to choose a probiotic
Benefits are specific to the strain, not the brand or the CFU count. Our dietitian's checklist:
- Look for strains studied for your goal, listed by full name (e.g. L. rhamnosus GG).
- Check the count is guaranteed through the expiry date, not just “at manufacture”.
- Give it 4 weeks. If nothing changes, stop rather than paying for it indefinitely.
Eating for your gut matters more than any supplement. Read our gut health guides.
This tool is for general education, not medical advice. If you have blood in your stool, unexplained weight loss, ongoing diarrhea or severe pain, see a doctor. If you are pregnant, immunocompromised or seriously ill, ask your doctor before taking a probiotic.
