Thank you for helping me with IBS D. I am doing well. Your organization has helped me immensely and given me my life back.
Jill B.
I was diagnosed with health issues at age five that were clearly due to a disrupted gut microbiome. I am 59 now and it has taken me 40 years to get my health back on track by fixing my microbiome and your company makes it very easy for me to track my progress!
Michael S.
Amy was clear and easily understood as she explained the areas where I need support and further evaluation.   Thank you so much for this analysis which I desperately needed!
Lynn T.
My lab results were truly an eye-opening experience. Although the report was provided in daunting details, my consultant was able to guide me through the information.

I've been getting into gut health over the last couple years and have even taken other test kits. Tiny Health definitely is leading
the space with their knowledge and reporting. I haven't even done the consult yet, which I'm looking forward to. Great work!
Brad W.
The incredibly detailed results provided by the TinyHealth adult gut test have been invaluable to support my recovery! I am SO grateful for this resource and feel empowered to take steps in the right direction. Overall I really loved the experience from start to finish!
Ashley W.
I am very happy and excited to start the healing process.
Maria
It was good to know which issues I needed to work on with suggestions.. comforting to know just where I'm at and how to make things even better..
Diane
I've had to be on antibiotics for 2 surgeries and I thought just eating fermented foods would get me back on track.  I appreciate so much having a targeted plan for me to do for the next four months to help get my gut back on track. Without Tiny Health I was shooting in the dark.
Valerie
Tiny Health has been very helpful in providing insight to my gut health while proving me with ways to help improve it.
Kate
This has already been a life-changing experience. I spent decades trying to get answers through the traditional health care system, which only created more suffering through incorrect (and insulting!) diagnoses like anorexia rather than addressing the gut problems I have experienced since childhood. To see my results presented this way is truly so validating and empowering.
Kathleen
I have been using Tiny Health now for almost two years. Without their help, I was just shooting in the dark, but with the results from my gut and their advice, I was able to go from being in the 1st percentile on my first test, to now being in the 84% percentile (on my third test), which I am very happy about. Not only is it nice to see the numbers on the screen, I feel better! I can tell the difference.
Tetyana
Tiny Health helped me have clarity and mental relief to finally understand what is going on inside of my body. Having an action plan to help me adjust areas that need attention and understanding what my body needs was a HUGE benefit. I loved the personal touch of the consultation call that helped me understand what I should prioritize and how my gut is interacting with different areas.

Frequently asked questions

Why is gut health important? Is testing really worth it?

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.

How does testing work? What do I have to do?

For our gut test 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.

‍

How solid is the science?

Microbiome health as a field is relatively new compared to medicine in general. However, human microbiome research has grown over the past 10 years and rose exponentially in the past five years as sequencing technology became more affordable.
‍
There are now more researchers looking closely at how the microbiome is related to health and disease. When it comes to the baby microbiome and associations with health or disease, some very clear patterns have emerged. We pull data and reference high-quality research that is reproducible and gives consistent results. This way, you can be confident in the information that we share.

‍

What does a Tiny Health test look for? What is included?

Tiny Health screens for over 120,000 microbes. This includes bacteria, fungi, parasites, viruses, and archaea found in the microbiome. Each microbiome test kit includes a mess-free stool or vaginal swab with instructions. You return your kit in the pre-paid mailer, which goes to our CLIA-certified and CAP-accredited laboratory partner for microbiome sequencing. In 3-4 weeks, you receive a precision report of your results. This includes personal, evidence-based suggestions to improve your gut or vaginal health.

Summary + Expert Highlight
Your summary gives you a bird’s eye view of your gut or vaginal health report. This includes a customized plan prepared by one of our microbiome experts.

The expert highlight guides you through the results. We help you understand what the data means and which actions to take first.

Key Insights
Learn about current imbalances that are important for your specific age. This means a 4-month old gets different metrics from a 12-month old. And a 2-year old gets different metrics than a 40-year old.

Microbiome Breakdown
You receive a comprehensive list of all microbes found in your sample. We categorize them as beneficial, unfriendly, variable, or unknown and provide detailed descriptions of each microbe. You can see how much of each microbe is present, down to a 0.05% abundance level. (No other baby gut test does this!)

Conditions
This section of the report identifies if you have microbiome signatures for certain conditions. These markers could predict an increased risk of developing that condition.

Action Plan
We provide personal, evidence-based suggestions based on your test results and survey responses. Our suggestions may include actual products and brands that we recommend. You'll also receive useful diet, supplement, and lifestyle tips.

Curious? Explore a Sample Report

My doctor has never heard of this type of microbiome testing. Why should I take a test?

Conventional medical providers usually are not trained in microbiome testing and probiotics, since these things aren't currently standard of care in those settings. In addition, many conventionally trained physicians also have limited nutritional training, and diet is one of the most powerful ways you can optimize microbiome health. While conventional medicine can have lots of insight into sick care, it isn't always the best at wellness and prevention. Plus it can take 10-15 years for the medical field to put new academic research into practice!

‍But that doesn’t mean that it’s something to wait on. Enter Tiny Health.

‍Our team of leading pediatric scientists and physicians are on the cutting edge of microbiome health. We are prevention and wellness focused. We've developed tests to give families access to this innovative science right now.

Can a gut test help with eczema, allergies, or asthma?

Eczema, allergies, and asthma are inflammatory conditions. Tiny Health microbiome tests help you identify inflammation at its source, your gut. With deep insights into your gut microbes, you can take action and help prevent or reduce inflammation in your body.

Here are two ways caring for your microbiome can help with inflammatory conditions:

1. In our first few years of life, our gut microbes help train our immune system how to behave. Without proper training, our immune system can contribute to long term issues with inflammation (e.g., eczema, allergies, asthma). The goal is to address imbalances early. That way, the immune system has proper education. This may even help prevent inflammatory conditions from developing.

2. At any age, the microbiome can become unbalanced. This may trigger inflammatory symptoms in our bodies. This can weaken the gut lining, cause leakiness or inflammation, and trigger the immune system. It is important to address these imbalances. Better gut health is possible at any age.

Tending to your gut health is beneficial for overall health and wellness. But your gut may not be the only factor contributing to inflammatory conditions. Many families have successfully reduced or eliminated symptoms by testing and taking action. When you use Tiny Health tests, you can rest assured that a team of gut health specialists are here to support your health journey.

Can a microbiome test tell me about lactose, dairy intolerance, or specific food allergies?

No, a gut microbiome test kit cannot detect lactose intolerance or specific food sensitivities.

At Tiny Health, we can help you understand your gut health and how it may contribute to symptoms of these food sensitivities.

Lactose intolerance refers to trouble digesting the milk sugar, lactose. It is different from cow milk protein allergy, which involves an immune response. Cow milk protein allergy is somewhat common in babies. But lactose intolerance is very rare in children under the age of 5 years old.

There are two types of lactose intolerance:

1. Primary lactose intolerance: This is rare in babies and all about genetics. In this case, the body cannot make enough of the enzyme lactase. This is the enzyme that helps break down and digest the lactose milk sugars.Primary lactose intolerance is not caused by gut microbes. But symptoms may improve with helpful bacteria like Streptococcus thermophilus.

2. Secondary lactose intolerance: This is all about damage to the gut lining. Lactose digestion takes place in the small intestine. Damage to the lining of the small intestine can lead to secondary lactose intolerance. Usually this happens in adults, after a long period of gut inflammation.

Gut microbes can cause lactose intolerance if they are causing gut inflammation. Repairing the gut and clearing inflammation can help support lactose digestion.

If you or your child is having issues with a food sensitivity, talk to a healthcare provider. It is important to understand the root cause. Specific food allergies and sensitivities are often determined by a blood test.

However, for children who are reactive to a wide variety of foods, the common cause may be related to an imbalance in the microbiome, and less the individual foods. Inflammation in the gut may damage the gut lining, and gut leakiness may permit dietary triggers to get into the rest of the body, triggering reactions. For some children, healing the gut can reduce their reactivity to foods.
