Feeling tired, bloated, or moody? Check your gut – specifically, your gut microbiome.
The gut microbiome has become a big buzzword in wellness, and for good reason. Research shows that more than 70% of the body’s immune system resides in the gut, and every gut microbiome is unique. A balanced gut doesn’t just support digestion; it influences energy, mood, metabolism, and even how the body responds to stress. Understanding what your gut bacteria produce and how the body reacts can offer powerful clues to overall health.
The problem? You can’t fix what you don’t know. Until now, testing the gut microbiome has involved either visiting a clinician or collecting a small stool sample at home to ship to a lab. Options that many people found inconvenient or, let’s be honest, unpleasant.
Now, an at-home test from Scandinavian health and wellness company Zinzino is changing that. The first-of-its-kind gut health test makes it as easy as a quick finger prick, paving the way for the future of personalized gut health.
Based on metabolomics, the large-scale study of small molecules, called metabolites, within a biological system, the blood sample measures how gut bacteria communicate with your metabolism. With just a few drops of blood collected at home on filter paper with a finger prick, users send the sample to Zinzino’s lab and receive a personalized report within weeks. The kit even includes a follow-up test after 120 days to track the body’s response to diet and lifestyle adjustments.

Why Gut Health Matters
Your gut is so much more than just where you digest food. It’s often referred to as the “second brain” because it communicates directly with the nervous system through the gut–brain axis. This powerful control center sends signals throughout the body that affect metabolism, mood, the immune system, and more.
“Think of your gut as an ecosystem,” says Dr. Martina Torrissen, Director of Research and Development at Zinzino. “When it’s balanced, good bacteria crowd out the harmful ones and create compounds that keep your metabolism and immune system running smoothly.”
When the gut microbiome is in balance, it breaks down what you eat into compounds that support your health. When it’s out of balance due to lifestyle or health factors, results can be wide ranging, from fatigue and bloating to brain fog and more. Whether you’re at the start of your health journey or focused on prevention and optimization, this gut-metabolic balance test gives you a deeper view of what is happening beneath the surface.
One Step Beyond
The new test from Zinzino goes beyond simply identifying what microbes are present in your stool. It focuses on what those microbes produce which are the metabolites circulating through your bloodstream that reveal how your gut and body communicate. The results provide a meaningful picture of microbial activity through more specific markers that directly flag fiber intake, immune stress, and immune activation – aspects that stool tests cannot capture on their own. If the test results show an imbalance, Zinzino also provides recommendations to support better gut health – such as managing stress, limiting ultra-processed foods, and increasing fiber intake.
The Benefit
“The goal is to empower people to take charge of their wellbeing,” explains Colin Robertson, Chief Product Officer at Zinzino. “It’s about seeing how your lifestyle choices translate into measurable changes inside your body.”
Accessible knowledge of the gut microbiome provides a lifestyle compass right in the palm of your hands. And the path to overall health and well-being is made even clearer.
