Most gut tests only tell you which bacteria are present. This test tells you what they’re actually doing inside your body.
The Zinzino Gut Health Test is a breakthrough in functional gut analysis. Instead of asking you for a stool sample (which most people hate doing), this test uses a simple finger-prick dried blood spot to reveal how well your gut microbiome is functioning, how it is influencing your immune system, and whether your body is in a balanced or stressed state.
This information goes far beyond digestion, it connects directly to your mood, hormones, metabolism, inflammation, skin health, energy levels and overall wellbeing.
What Makes This Gut Test Different?
Unlike stool-based microbiome tests that only identify which bacteria are present, the Zinzino Gut Test measures your gut’s functional output, the substances your gut bacteria are producing that directly influence your health.
It does this by analysing three key tryptophan-derived compounds, which act like “messengers” between your gut, immune and metabolic systems:
The 3 Compounds Measured
Indole-3-Propionic Acid (IPA)
A beneficial anti-inflammatory metabolite produced exclusively by gut bacteria
Supports a strong gut barrier, antioxidant protection and metabolic health
Tryptophan (TRP)
An essential dietary amino acid
Precursor used by gut bacteria to make IPA or by your immune system to make Kynurenine
Kynurenine (KYN)
A metabolite produced when your body is under immune stress
Higher levels may indicate inflammation or immune activation
These three markers reveal which “pathway” your tryptophan is flowing into:
✔ the beneficial gut-bacteria pathway (IPA) or ✔ the stress/inflammation pathway (Kynurenine)
This is why this test is so powerful, it shows what your gut and immune system are actually doing in real time.

The 5 Key Health Markers You Receive
Your results page gives you five easy-to-read insights:
✔ 1. Gut Health Index
A single score summarising your gut-immune-metabolic balance.
✔ 2. IPA Level
Shows how well your gut bacteria are producing beneficial metabolites.
✔ 3. IPA:TRP Ratio
Indicates gut microbiome efficiency – how effectively bacteria convert tryptophan into IPA.
✔ 4. KYN:TRP Ratio
Shows immune stress and inflammation activation.
✔ 5. IPA:KYN Ratio
Reveals the balance between protective gut activity and immune-driven metabolic stress.
This is real science, made simple, visual and easy to understand.
Why Tryptophan Metabolism Matters So Much
Tryptophan is a “crossroads molecule. ”Your body can route it into two different pathways:
Pathway 1: Gut Bacteria → IPA
This is the healthy, protective, anti-inflammatory route. IPA is linked to:
Stronger gut barrier function
Better metabolic flexibility
Healthy blood sugar regulation
Improved immune resilience
Reduced oxidative stress
Pathway 2: Immune Activation → Kynurenine
This increases when the body is stressed or inflamed.
High Kynurenine may reflect:
Immune activation
Chronic stress
Systemic inflammation
Disturbed gut balance
This test shows which pathway your body is using more and how balanced you are.
Benefits of the Gut Health Test
Your gut influences everything from digestion to brain function. This test helps you:
Short-term (2–6 weeks)
Reduce bloating
Improve bowel patterns
Feel less sluggish after meals
Experience calmer digestion
Medium-term (6–12 weeks)
Notice clearer skin
Feel more energised
Improve mood stability
Reduce inflammatory flare-ups
Long-term (3–12 months)
Strengthen immunity
Improve metabolic balance
Support hormonal health
Enhance resilience to stress
This is what “inside-out wellness” truly means.

FAQs
Is this a stool test? No. It’s a simple dried blood spot, much easier and cleaner.
Does it diagnose medical conditions? No, it provides wellness insight, not medical diagnosis.
Is this test useful if I have IBS, inflammation or skin issues? Yes, gut dysfunction often influences all of these.
How often should I repeat it? Every 120 days for the most accurate tracking.
