Gut Health Test
Is life going your way?
Listen to your gut – it drives your health.
Your gut holds 70% of your immune system* and every gut is different. Testing your gut with a drop of blood changes the game.
Know your gut. Own your health.
What you eat and how you live influence whether your food becomes fuel, or triggers your body’s stress responses. When your gut’s in balance, it supports your whole body. If it’s not, it can impact your energy levels and resilience.

The next generation of gut health testing

The first-of-its-kind dried blood spot home test to unlock insights for a thriving gut and healthy body – all in a drop of blood.
What’s in it for you?
A preventative health and lifestyle measure in a single drop of blood, no stool samples needed.
Actionable insights into your gut-metabolic balance from five different health markers.

Track hidden signals to determine whether your immune system is in balance or under stress.
A chance to tailor a diet and lifestyle routine based on what your gut needs.
Here’s how to start your journey
Your gut is talking. Find out how to listen.
Our scientists have discovered a unique window into your gut functions based on how your body metabolizes a key amino acid from food. By looking at what signals this process leaves in your blood, the test reveals how your gut and body work together to support overall health, presented in 5 different health markers.
Tryptophan (TRP)
An essential amino acid your body and gut bacteria use to make important metabolites – like IPA and KYN – that influence gut and metabolic health.
Indole-3-propionic acid (IPA)
When eating quality high-fiber food, good bacteria thrive and turn tryptophan into the gut-protective metabolite IPA to promote immune function and better metabolic health in the body.
Kynurenine (KYN)
If your diet is poor, bad bacteria get the upper hand, and tryptophan is metabolized into the stress-responding metabolite kynurenine, which is your body’s way of activating immune defenses to fight the imbalance.
Gut Health Index
Your overall gut results providing a snapshot of how your gut, immune and metabolic systems work together to support your body.
IPA Level
How much of the health-supportive metabolite IPA your gut bacteria produce to keep your metabolism in balance.
Microbiome Immune Support
Reveals the balance between gut-protective IPA and stress-responding kynurenine.
Gut Microbiome Efficiency
Shows how well your gut bacteria turn tryptophan into the gut-protective IPA.
Immune Stress Indicator
Highlights how your immune system is responding – whether it’s under stress, or in calm and more balanced state thanks to your gut’s protective mode.
