No, this is a gut‑metabolic balance test. Traditional microbiome (stool) tests look at which bacteria live in your gut. Our Gut Health Test instead measures what trey do, through signals in your blood that reflect how your gut interacts with your metabolism. By combining these signals, the test provides an overview of your current gut‑metabolic profile. No stool sample is required — just a drop of blood from a simple finger prick — offering convenient, non‑invasive insights related to your diet and lifestyle.

Traditional stool tests show which microbes are present in your gut, but presence alone does not reveal their activity. The Gut Health Test instead measures specific signals in your blood, including metabolites produced by gut bacteria and how your body processes tryptophan, an essential amino acid from food. Beyond digestion, the gut contributes to how nutrients are processed and how certain compounds are formed. Tracking these signals helps you understand more about your gut‑metabolic profile, offering convenient insights into how your gut and metabolism interact. Unlike stool tests, this method requires only a simple finger‑prick blood sample.

Stool tests can show which microbes are present in your gut, and that information is useful for research. But presence alone doesn’t reveal whether those microbes are active, what they are producing, or how your body is responding to them. Our Gut Health Test goes a step further by measuring specific metabolites in your blood. This gives an indirect picture of microbial activity (through indolepropionic acid, produced by certain gut bacteria) and tryptophan metabolism (through the KYN/TRP ratio). These markers are scientifically associated in research with gut microbial diversity, dietary fiber intake and aspects of immune system function, providing complementary insights that stool tests cannot capture on their own.

Your test results are presented as five clear, science‑based markers, offering insights into how your gut microbes and your body interact. Each marker highlights different ways your gut bacteria process metabolites and how these signals reflect whether your metabolism is leaning toward balance or toward immune‑related activity. Your test results are analyzed in strict confidentiality by Vitas AS, an independent chemical analysis laboratory, before being translated into a personalized test report. The information in your report is based on a single drop of blood, measuring three metabolites (IPA, KYN, TRP) and their ratios (IPA/KYN, IPA/TRP, KYN/TRP). These insights are intended to help you better understand your gut‑metabolic profile and how it relates to your current diet and lifestyle. You can use them as a guide when considering a personalized diet and supplement routine to support your overall wellness, alongside professional advice where needed.

All samples are analyzed by Vitas AS, an independent chemical analysis laboratory and a world leader in dried blood spot testing. The analytical method is based on established technology, and a formal validation study has confirmed its accuracy and reliability.

You take the test in the comfort of your home. No messy stool collection is required — just a drop of blood from a simple finger prick. It only takes a few minutes, and your results are available at zinzinotest.com within three weeks. The metabolites measured can vary depending on dietary intake throughout the day. To ensure consistency, we recommend taking the test on an empty stomach in the morning after a water‑only overnight fast of at least 10 hours.

The state of our gut health is dynamic. Any changes in lifestyle, diet, or daily routines can affect how we respond to food and our nutritional uptake. This test measures your tryptophan metabolism and gut‑related microbial activity, both of which are influenced by what you eat and how you live. That’s why we suggest taking two tests. The first provides a baseline measure of your current profile. To remind you when it’s time to check your progress, you’ll receive your second test separately after four months. This interval offers a way to observe how your profile may reflect dietary or lifestyle changes, and gives you the opportunity to make adjustments if you wish to support your gut‑metabolic balance.

For the Gut Health Test, there is not enough scientific data to support child‑specific values, so we mainly recommend the test for adults. The same metabolites are measured in both children and adults, but the target values are based on scientific data primarily from adults. Children’s metabolism and gut microbiota are still developing, which means their levels may not be directly comparable to adult values. The test can still provide exploratory insights for children, but results should be interpreted with caution. Over time, as more data become available, specific reference values for different age groups may be established.

Your Gut Health Index gives you a snapshot of how your gut, immune, and metabolic systems interact. This index is dynamic and can change with your diet, lifestyle, and overall physiological state. Research shows that factors such as consuming fiber and prebiotics, balancing dietary fats, and managing stress may influence your microbiome and metabolism. Over time, these choices can be reflected in your Gut Health Index.

These markers are influenced by many factors, including diet, lifestyle, genetics, and the overall physiological state of your body – so we cannot guarantee that your results will improve. What we can say is that research shows certain choices may be associated with positive changes: increasing fiber intake (ZinoBiotic+), balancing fatty acids (BalanceOil+), and supporting nutrition with vitamins, minerals, and beta‑glucans (Xtend/Xtend+). These supplements are designed to complement, not replace, a healthy diet and lifestyle. For those aiming to support their gut‑metabolic balance, we recommend focusing on a diverse, whole‑food diet (whole grains, vegetables, leafy greens, legumes), including fermented foods (such as kimchi, sauerkraut, yoghurt with live cultures), polyphenol‑rich plant foods and extra virgin olive oil, along with regular physical activity, stress management, quality sleep, and caring for your general wellbeing. Zinzino supplements are intended to complement these healthy choices by providing additional nutritional support.

Yes. The test is based on established scientific research into tryptophan metabolism and its associations with gut and metabolic health. The markers measured (IPA, KYN, TRP, and their ratios) are widely studied in peer‑reviewed science as indicators of microbial activity and immune‑related processes.

All analyses are performed by Vitas AS, an independent chemical analysis laboratory recognized internationally for its expertise in dried blood spot (DBS) testing. The analytical method is validated, and the findings are supported by a growing body of international research into the role of these metabolites in gut‑microbiome interactions and metabolic pathways.

Metabolic health reflects the way your body balances energy and nutrients in daily life. It refers to how efficiently your body converts food into energy and maintains balance across key functions such as blood sugar regulation, fat metabolism, and energy use. When these processes function efficiently, people often experience consistent energy and daily wellbeing. These processes can be influenced by diet, lifestyle, and overall physiology. Research suggests that factors like dietary fiber intake, a diverse gut microbiome, balanced nutrition, regular physical activity, and stress management may be associated with healthier metabolic patterns. When these systems are not functioning optimally, people may notice effects such as fatigue, changes in weight, or reduced focus.

Gut microbial activity describes what your gut bacteria are doing — how active they are, how they break down food, and what they produce as a result. If your gut is imagined as a factory, microbial activity is like the work carried out by the bacteria. The Gut Health Test does not measure everything your microbes do directly. Instead, it looks at key metabolites in your blood that reflect both microbial activity and your body’s responses. This provides an indirect overview of how diet, lifestyle, and gut microbes interact.
