If you’ve ever wondered what’s really going on inside your gut (or why your GI tract has been acting like it’s in its dramatic era), you’re not alone — more than 100,000 people have now turned to Tiny Health, the microbiome platform that’s blowing up across the wellness world.
The Gut Test That Started With Babies and Ended Up Helping Everyone
Tiny Health originally launched in 2020 with a wholesome mission: help parents understand their baby’s gut from day one. Yes, baby gut health is a thing — and it affects their risk of developing eczema, allergies, and other chronic health issues. In fact, Tiny Health’s infant gut test is the only clinically validated one on the market, with research showing its personalized recommendations can cut a baby’s odds of eczema by 83%.
The plot twist?
Adults wanted in, too.
Now Tiny Health has evolved into a go-to resource for anyone trying to fix digestion, boost immunity, or simply age better. And unlike some wellness brands that push their own products, Tiny Health doesn’t sell supplements at all, so the advice is based on actual science rather than profits.
“Hitting 100,000 users shows that people are done guessing about their bodies,” said Cheryl Sew Hoy, Founder and CEO of Tiny Health. “They want real answers, real science, and real results. Tiny Health started by giving families the power to prevent and reverse chronic disease in their babies, but now adults everywhere are realizing their gut health is crucial, and our tests provide clear, science-backed guidance to help them feel better and understand their microbiome like never before.”
The At-Home Gut Test People Can’t Stop Talking About
Tiny Health’s test is one of the most advanced at-home microbiome tests available, using shotgun metagenomic sequencing, the same ultra-detailed method used in cutting-edge research.
It can identify more than 120,000 species of bacteria, viruses, parasites, fungi, and more (yes, your gut is basically a microscopic metropolis) and shows:
- Exactly which bacteria are thriving or missing
- What those microbes are actually doing
- Whether your probiotic is even working
- Signs related to digestion, inflammation, hormones, metabolism, energy, and aging
The result is a clear, plain-language breakdown of what your gut looks like — and what you can do to support it.
Why the Gut Has Become the Main Character
Up to 80% of your immune system is in your gut, making your microbiome foundational to your health. And it starts early: the first 1,000 days of life shape your immune system, while gut changes in adulthood can impact metabolism, mood, and longevity. That's why Tiny Health partners with leading longevity clinics, personalized medicine platforms, and major health systems to bring microbiome insights into everyday care.
“Our science gives people a real-time view of how their microbiome impacts aging, metabolism, hormone regulation, and disease risk,” said Sew Hoy. “It’s a personalized health dashboard for your gut, built on one of the most comprehensive microbiome datasets in the world.”
