Tiny Health Celebrates 100,000 Tests Milestone, Expands from Baby Gut Health Pioneer to Longevity Innovator
The microbiome startup powering preventive and personalized health launches new aging study and deepens partnerships with leading wellness and longevity programs
AUSTIN, Texas, Dec. 10, 2025 (GLOBE NEWSWIRE) — Tiny Health, the first precision microbiome wellness platform built for lifelong health, today announced it has surpassed 100,000 people and 3,000 health practitioners utilizing its microbiome tests.
Founded in 2020, Tiny Health began with a mission to help parents uncover and correct early gut imbalances in babies — a critical step in preventing chronic conditions like eczema, food allergies, and asthma. It is the only clinically-validated gut test for babies, with a published randomized controlled trial showing that Tiny Health personalized microbiome support reduced infants’ odds of eczema by 83%.
Today, its science and technology are helping people of all ages strengthen gut resilience, extend healthspan, and personalize care through a growing network of medical and wellness partnerships.
“This milestone is evidence that microbiome health is becoming mainstream,” said Cheryl Sew Hoy, Founder and CEO of Tiny Health. “We started by giving families the power to prevent and reverse chronic disease in their babies, and now we’ve expanded into longevity and healthy aging alongside major health systems, longevity clinics, and personalized medicine brands to help adults take control of their health with the same level of scientific rigor.”
From the First 1,000 Days to the Last 1,000 Days: Translating Microbiome Science Across the Lifespan
Tiny Health’s research has shown how the first 1,000 days of life — when the gut microbiome trains the developing immune system — set the foundation for lifelong health. By examining microbial patterns shared between well-trained infant immune systems and resilient aging microbiomes, the company aims to uncover how early-life microbial education influences vitality later in life. This new focus bridges decades of microbiome research, connecting the mechanisms that support thriving beginnings with those that sustain healthy longevity.
Tiny Health uses shotgun metagenomic sequencing to map gut health with strain-level precision and quantifies functional pathways of critical modulators in the gut. This year, the company has introduced new functional insights into the adult microbiome, including Gut Resilience, Urolithin-A potential, GLP-1 production, beta glucuronidase, and markers tied to conditions such as IBS and menopause.
“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.”
