Zinzino Gut Health Test: Experience the Next Generation of Gut Health Testing

Discover what’s really happening inside your digestive system with the Zinzino Gut Health Test, an advanced at-home analysis designed to reveal the balance and diversity of your gut microbiome. Your gut health influences everything from your skin and immunity to your mood and metabolism. This simple test offers a science-based way to understand your unique microbiome and make targeted changes to support long-term wellbeing.

Gain a detailed overview of your gut ecosystem, including the diversity and ratio of beneficial bacteria, microbial balance, and the presence of key bacterial strains. The easy-to-use kit includes everything you need for discreet, hygienic sample collection from the comfort of your own home, with no clinic visit required. Samples are processed in a certified third-party laboratory using advanced sequencing technology, ensuring accuracy, confidentiality, and scientific reliability.

Your personalised report explains your microbiome in clear, easy-to-understand terms, highlighting areas of imbalance and offering practical nutritional guidance to help restore harmony. Based on your results, Zinzino provides tailored recommendations to support gut health, including the use of targeted fibres, prebiotics, and probiotics such as ZinoBiotic+, their signature eight-fibre blend designed to nourish beneficial bacteria.

You can repeat the test after several months to monitor how your microbiome responds to dietary or lifestyle changes, allowing you to see measurable improvements and refine your approach. Results are accessed securely through an online dashboard, giving you visual insights and ongoing access to your data.

Modern living, stress, processed foods, and antibiotic use can all disrupt the delicate balance of your gut microbiota. Even small imbalances can affect digestion, immunity, skin health, energy, and mood. The Zinzino Gut Health Test helps you move from guesswork to genuine insight, empowering you to take meaningful steps towards better health from the inside out. This test is a wellness tool designed for educational and lifestyle purposes and is not intended to diagnose or treat medical conditions.

The Zinzino Gut Health Test is ideal for anyone wishing to understand and improve their gut health, those experiencing digestive discomfort or bowel irregularity, individuals seeking a personalised approach to nutrition and wellbeing, and those who wish to track microbiome changes over time.

The Zinzino Gut Health Test focuses on three scientifically important compounds and key ratios:

• Indole-3-propionic acid (IPA) – IPA level – a beneficial metabolite produced exclusively by gut bacteria from dietary tryptophan. Higher levels are linked to stronger gut barrier integrity and protection against oxidative stress. IPA is increasingly recognised as a key indicator of gut microbiota function and overall resilience.

• Tryptophan (TRP) – an essential amino acid obtained from the diet that serves as the precursor (starting material) for both IPA and kynurenine. Tryptophan availability and how it is metabolised can influence gut health, immune function and metabolic balance.

• Kynurenine (KYN) – a metabolite produced from tryptophan through the kynurenine pathway, often activated by increased immune stress. Higher kynurenine levels and an elevated KYN: TRP ratio are linked to increased immune activation and a shift away from beneficial microbial metabolite production.

Key Ratios:

• IPA: TRP ratio – Gut microbiome efficiency – reflects the proportion of dietary tryptophan converted by gut bacteria into IPA, influenced by gut microbiota composition and diet.

• KYN: TRP ratio – Immune stress indicator – an established marker of immune activation and load.

• IPA: KYN ratio – Microbiome immune support – a relative balance score showing the relationship between protective and stress-driven pathways in tryptophan metabolism.

Your report also includes a Gut Health Index, integrating all measured markers and ratios into a clear, easy-to-understand overview of your gut-immune-metabolic balance.

Why tryptophan metabolism matters:

Tryptophan metabolism is increasingly recognised as a critical hub connecting gut, immune, brain, and metabolic health. Gut bacteria transform tryptophan into a range of indole metabolites, including IPA, a health-supporting metabolite that supports gut barrier integrity, modulates immune responses, and helps protect against oxidative stress.

Emerging research shows that higher IPA levels are linked to metabolic flexibility, glucose regulation, and immune function. Conversely, when tryptophan metabolism is dysregulated, more of it is diverted into the kynurenine pathway, a route often triggered by your body’s stress responses.

This metabolic crossroad between the body and gut bacteria is no longer a scientific curiosity; it is now seen as a cornerstone of intestinal and systemic homeostasis. By decoding your tryptophan metabolism profile, the Zinzino Gut Health Test reveals the functional output of your gut bacteria and how it relates to immune and metabolic pathways, empowering you to make targeted, evidence-based changes to support long-term health from the inside out.

Certified & secure testing:

• Independent laboratory – analysed by Vitas, a GMP-certified lab with 25+ years of experience in high-quality chromatographic analysis.

• Anonymous results – your sample is linked only to your unique test ID; neither Zinzino nor the lab can identify you.

• Certified kit – complies with EU regulation 98/79/EB for in vitro diagnostic medical devices and carries the CE mark.

Taking your test:
For optimal accuracy, perform this test on an empty stomach. Take your test in the morning after an overnight fast of at least 10 hours and complete it before consuming any food.

Only water is permitted during the fasting period. The Zinzino Gut Health Test is an approved in vitro diagnostics product for personal blood sample collection at home.

First, wash your hands with soap, rinse them well with warm water, and then dry them.

Take out the Zinzino Gut Health Test sample card from the paper envelope. Save the envelope for later use.

Tear off the SAVE part on the sample card and take a picture of the Test ID. You can ONLY see YOUR test result with your anonymous Test ID. Place the card with the two circles facing up on the table.

Stimulate blood flow by making big circles with your arm or shaking your hand downwards for 20 seconds.

Take out the single-use lancet. Remove the transparent safety cap, and the lancet is ready to use.

Use an alcohol wipe to clean the tip of your finger (the middle finger is recommended).

Place the lancet against the lower part of the fingertip, ensuring it faces the collection paper on the table. Push the top of the lancet towards the finger until you hear a click. The lancet will automatically make a small prick in the finger.

Do not touch the filter paper with your fingers.

Fill one circle at a time with blood. Squeeze your finger gently and wait for a drop of blood to fall inside the circle by itself. If one drop of blood does not cover the circle, allow one more drop from your finger to drip immediately.

Leave the Zinzino Gut Health Test sample card in a horizontal position at room temperature for at least 10 minutes to ensure the samples dry well.

Insert the sample cardback into the paper envelope. Then place the paper envelope into the metal bag andclose it.

IMPORTANT: Do not remove the desiccant packet inside the metal bag. Place the closed metal bag into the big envelope with the laboratory address on it.

NOTE: You MUST put the correct amount of postage stamps on the envelope before you put it in the mail box.

IMPORTANT:
Keep the SAVE part of the card. You can ONLY see YOUR test result on the internet with your anonymous Test ID.
