About Tiny Health

Tiny Health is the first gut health test created for mom and baby

Tiny Health offers at-home gut tests for the whole family. We focus on a baby’s first 1,000 days to address imbalances that may cause chronic conditions such as allergies. With comprehensive shotgun metagenomics sequencing, Tiny Health gives parents key insights and actionable recommendations to improve a baby’s lifelong health.

Developed by researchers from

The first 1,000 days of your baby’s life can be tough

Tough on them. And on you, too. The uncertainty. The second-guessing. The sleepless nights. The constant wondering that you may get it “wrong” even though you do everything “right.” Babies don’t come with an instruction manual. And it’s hard to know why your baby isn’t feeling their best.

The answer is in your baby’s gut

Fussiness, sleep issues, reflux, eczema, food allergies, and even some long-term conditions like asthma, and type 1 diabetes link back to your child’s microbiome development during these crucial first 1,000 days.

Their immune system may need a little help

A C-section birth, antibiotics, formula use, or living in an over-sanitized, urban environment can impact your baby’s immune system. Tiny Health helps you pinpoint any potential issues and jumpstart their health.

The first gut test designed for babies

Tiny Health was founded by a mom who wanted to test her baby’s gut trajectory after her C-section and couldn’t find a straight answer in the market. Our test is the first to measure what matters most to babies. Other gut tests use “adult reference ranges,” which are entirely different from babies' ranges and lead to incorrect conclusions.
