Frequently asked questions
How does VitalOme work?
You receive the kit at home. You take a small stool sample at home (a process that takes just a few minutes) and send it to the laboratory in the included return envelope. The laboratory processes the sample in approximately 2 weeks from receipt. The total time from your order — including kit shipping and sample return — is around 3-4 weeks.
Why does VitalOme cost less than other similar tests?
VitalOme uses state-of-the-art NGS (Next Generation Sequencing) technology, the same used by brands that charge between €338 and €390 for equivalent tests. Our goal is to make clinical-quality microbiome analysis accessible to those who want to take care of their health without overpaying.
What sets VitalOme apart from InnerBuddies, which is cheaper?
InnerBuddies has a base price of €179 and does not detail on its official website the number of health areas it covers. VitalOme, for €249, covers 17 health areas, including thyroid activity, gut-liver axis, blood glucose and blood pressure regulation — areas that InnerBuddies does not publish in its coverage. If you're looking for a complete analysis that goes beyond digestion, VitalOme offers significantly broader coverage for just €70 more.
Is VitalOme a medical test?
No. VitalOme is a wellness test that analyses the composition of your gut microbiome through DNA sequencing. It does not provide medical diagnoses. If you have symptoms or suspect any illness, always consult a doctor.
