“My son’s eczema and gas issues resolved completely”

“Tiny Health has been a wonderful resource for our family. My son was born via c section and had very poor gut health at his initial test. He suffered from mild eczema and bad gas. After a month on the recommended probiotic from the team at Tiny Health both issues resolved completely and at his follow up gut tests 2 month later his gut biome had improved immensely. We are so glad to have this resource to help set up our son for the healthiest life he can have.”

"We were simply interested in our baby's microbiome but then..."

Initially we were simply interested in the microbiome of our baby, and he turned out to have low levels of bifidobacteria. We found that a few days of a recommended probiotic already solved that problem! Then things got more serious. At 6 months old he was hospitalized with severe pneumoniae, and needed the most extreme antibiotics to save his life. It took a while but after months of following Tiny Health's advice, no trace of potentially antibiotic-resistant bacteria are left!

"Tiny Health is my greatest tip for expectant parents"

"As a mom to a child with allergies, I am grateful for these actionable suggestions to strengthen her microbiome. I only wish I had found it when I was pregnant: to identify and address my own low bifidobacterium levels, help me find strategies to navigate the use of cleaning products during COVID, and take restorative steps after her early antibiotic exposure."

"SO glad that I found Tiny Health, I only wish I had found them sooner!"

"I've worked with a functional medicine practitioner for years so I know how insanely important our gut health is, and I feel so great knowing that I'm taking steps now to ensure that my daughter's gut is as strong as it can be as she grows! I want to do everything I can to help her develop a strong immune system and Tiny Health has made that possible. The detailed action plan from her 7-day gut microbiome testing results made it so easy to find the right probiotic for her needs."

"Within days we saw a huge improvement in our baby's fussiness"

"I was at a loss when my 1+ month old son was suffering from colic and gas. It caused a lot of distress and sleepless nights. We decided to give Tiny Health a try because we suspected his microbiome might not be so good. They recommended that we get our baby on probiotics and within days we saw a huge improvement in his fussiness (he was sleeping better and wasn't crying as much!). We can't wait to do another sample when our baby is a bit older so we can see how his gut is performing."

“We were able to identify and take action on his condition early on”

“As a first-time mom, I didn’t realize the impact my diet during pregnancy could have on my baby’s microbiome.  Thanks to Tiny Healthy I was able to adjust my diet and take the necessary steps to ensure my baby’s health. After he was born, I tested him and followed Tiny Health’s recommendations.  After 4 months, we retook the test and saw a drastic improvement. We were able to take the proper preventative steps to make his immune system stronger.  We are so thankful!”

"Tiny Health provided me with clear data to support gut health"

"Tiny Health has really gone above and beyond in providing helpful and reassuring data from my vaginal and my baby’s gut test. With this pregnancy, I worked really hard on my gut health and I had no idea how much it affected the baby’s gut. If you are looking for the root cause of any issue or how to improve baby’s gut, Tiny Health's gut tests will lead you to those answers.

The first gut test designed with families in mind

Tiny Health was founded by Cheryl, a Mom looking to heal her baby’s microbiome after a C-Section birth. Unable to find clear, reliable answers anywhere she quickly realized that the only gut microbiome tests on the market were designed for grown-ups, not babies, leading to inaccurate results. She set out to create the first ever test to measure the microbiome health of babies during the critical first 1,000 days of life

Frequently asked questions

During the first 1,000 days of a baby’s life, a type of programming takes place. This programming helps to determine a child’s lifelong health and has been directly linked to a wide range of metabolic and immune mediated disorders that fit under the umbrella of chronic disease, sometimes referred to as noncommunicable disease or noninfectious disease. And because of something called epigenetics, programming can even be carried from one generation to the next.

No pressure or anything.

During a baby’s first 1000 days, you have the opportunity to make a big impact in everyday ways, like simple lifestyle or diet shifts.

As a baby grows, their gut matures and their immune system gets a little more skilled at identifying friend versus foe. Gut maturity is marked by diversity. After birth, the first major leap we see is when a baby begins eating solid food.

Parents have the biggest impact on a baby’s gut health during pregnancy and a baby’s first 12 months. As a toddler, there are gradual shifts towards a more diverse and adult-like microbiome that stabilizes between 3 and 5 years old.

Factors that affect baby gut health include vaginal birth or C-section, breastfeeding or formula feeding, and the use of antibiotics.

Please visit our Help Center for any question we may not have answered here.

We use a stool test collected with a lab-certified sampling swab from soiled tissue paper.

The process is simple and unlike other tests on the market, Tiny Health doesn't require gloves, a spoon-like collection device, or that you handle stool at all, other than on a regular tissue paper.

The sample is then stored in the included container and zippered back and mailed back to us on the prepaid envelope included with your kit.

In short, it’s never too late to test. The sooner you have a baseline sample, the better.

Keep in mind that the gut is still developing until the age of 3 - 5 years old. Up until this point, you have an opportunity to check in on your little one’s gut health and make changes, if needed.

For older children, testing can reveal a lot about their gut health. Including levels of hidden gut inflammation, levels of bacteria that make anti-inflammatory short-chain fatty acids, microbiome diversity, and biomarkers for immune health and fiber digestion.

Even if your child’s gut has reached adult-maturity, there’s still an opportunity to influence their dietary, supplement needs, and lifestyle choices.

Please visit our Help Center for any question we may not have answered here.

Conventional medical practitioners don’t get training for microbiome health and as such, are not always familiar with the latest research and recommendations in this field of medicine. However, our tests are developed by a team of leading pediatric scientists and physicians who are on the cutting edge of this impactful field.

Often, it’s up to your doctor to keep up on the latest research and most don’t have the time. In addition to this, it can take 10 - 15 years for academic research to be put into medical practice. So it’s possible that your doctor hasn’t heard about the gut microbiome.

But that doesn’t mean that it’s something to wait on. Especially during pregnancy and the first few years of life.

Recent studies show just how important the microbiome is to your baby’s immune development. You can use microbiome testing to make sure your baby has bacteria that protect health.

It is not possible to detect specific allergies or sensitivities through any gut microbiome test.

But we can show associations between your baby’s gut microbiome and their symptoms of eczema or allergies. Or the potential risk of these conditions developing.

How do we do this?

We use something called biomarkers. Microbial biomarkers are bacteria associated with a higher or lower likelihood of developing a particular condition.

Our microbial biomarkers are developed from research.

The Tiny Health Bioinformatics Pipeline uses a custom built database of over 120K complete microbial genomes. We sift through the research surrounding the microbiome and use this information to develop a list of bacteria that we feel are important to track in early life.

Beyond the gut, there are a lot of other factors that can contribute to these conditions. Like genetics, lifestyle, and environmental exposures. If your child has eczema or food allergies, Tiny Health can show whether or not biomarkers for these conditions are present. And how to best support gut health.

Emerging microbiome research has shown the importance of gut health to our overall health. The science links 80% of our immune system to the gut. So, taking steps to improve gut health supports lifelong wellness.

There are many tools and strategies to help improve your gut health. These include eating the best foods and taking supplements for gut health, or working with a gut health coach. Yet there is no one-size-fits-all approach to gut health. For example, taking a probiotic for the gut may be beneficial for some individuals. In others, it could do more harm than good. Imagine there’s already high levels of a beneficial microbe in your gut. Taking a probiotic could boost those levels to a point where they are too high, resulting in low diversity in the gut microbiome.

Taking a gut microbiome test is the best way to determine if there are any imbalances in your gut that need course correction. Testing helps educate you on the best actions for your unique microbiome. And you can retest to track if dietary changes and gut health supplements or probiotics are having the intended effect.

With a database of over 130,000 genomes mapped out, we’re able to provide:

  • A comprehensive list of all bacteria fungi, parasites, viruses, and archaea found in your baby’s microbiome
  • Your baby’s Tiny Health Gut Type
  • Key Insights about your baby’s microbiome and what this means for their health
  • Condition Biomarkers, which may give you clues about what’s happening in your baby’s body and the risk for specific conditions
  • Associations between any symptoms your baby might have and their microbiome
