The road to better health starts in your gut – not with guesswork

Today, we’re more focused than ever on understanding the impact of our diet and lifestyle on our bodies. But the human body is one of a kind, and knowing what your unique body needs isn’t easy. This is why we offer a range of at-home health tests designed to give you personalized insights into your body on a cellular level and how it responds to what you feed it. Our BalanceTest maps the levels of essential fatty acids in your blood, while our Gut Health Test reveals how your body reacts to the nutrients from your food by measuring signals in your blood.

• No one should have to guess their way to better health, says Colin Robertson, our Chief Product Officer.

Your gut microbiome is as unique as your fingerprint. It’s shaped by what you eat and how you live—and it forms the foundation for your journey toward a healthier life. Yet most of us are still in the dark when it comes to understanding how our gut really functions. We try new diets, supplements, and exercise regimes without truly knowing what our bodies need to perform at their best. We want to change that. By turning cutting-edge science into simple, everyday tools, we help people make informed health decisions based on facts, not guesswork. This is the key to taking control of our long-term health and well-being.

From gut feeling to measurable health

Since day one, we’ve challenged traditional views on personal health by combining blood-based testing with scientifically validated supplements. Instead of guessing what nutrients your body needs, you take a simple at-home test that helps you build a customized wellness plan based on your personal results. This test-based approach took off with our BalanceTest, which analyzes 11 fatty acids in the blood—including your Omega-6 and Omega-3 levels. Using six different health markers, you’ll receive a unique fatty acid profile to start a tailored BalanceOil+ routine to restore balance in your body’s essential fats, optimizing your brain, heart, and immune function.

We also offer a Vitamin D and HbA1c Test, and the new Gut Health Test, all following the same three-step principle: Test. Analyze. Balance.

Test, don’t guess

This proactive, test-based philosophy has made us pioneers in the global movement toward personalized, measurable health. Every health and wellness journey begins with a blood test to understand your baseline. From there, we provide insights and recommendations on diet, lifestyle, and—when needed—our scientifically proven supplements. Everything is designed to work from the inside out, adapted to your individual needs. The first test shows your current status and highlights potential nutritional gaps. After four months, you take a follow-up test to see how your body has responded and whether your plan needs adjusting.

Your immune system lives in your gut

Modern life brings stress, ultra-processed food, and long hours sitting down. We consume too much Omega-6 from fried foods and far too little Omega-3 from wild-caught fatty fish. Around 80% of people today are deficient in this vital fatty acid, and when it comes to fiber, only 10% of us meet the WHO’s daily recommendation of 25–35 grams. The gut influences so much more than digestion, and an unbalanced gut can send shockwaves throughout the body.

• We’ve all heard that good health starts in the gut—but it’s not just about digestion, says Colin Robertson. Around 70% of our immune system resides in the gut, which communicates directly with the brain and affects everything from sleep and mood to hormone balance.

Why blood tells a clearer story than stool

A healthy gut microbiome helps protect the body, while an unbalanced one can weaken its defenses. Stool tests that identify gut bacteria have been around for a while, but recent studies highlight their limitations. The focus is now shifting toward understanding how the gut actually functions and how the body responds. Everything your gut bacteria produce is shaped by your diet and lifestyle, which means the key lies in their activity, not just their presence.

Our Gut Health Test uses a simple finger-prick blood sample—no stool collection needed. You send your sample anonymously to Vitas AS, an independent chemical lab in Norway, and within two to three weeks, your personalized report is ready at zinzinotest.com

Using five key health markers, the report shows how your gut and metabolism are functioning and what lifestyle changes could help you optimize your gut health.

A lifestyle compass in your pocket

Think of your test results as a personal lifestyle compass—a chance to see whether your current diet and habits are truly sustainable. Is your immune system balanced? Is your gut functioning as it should? Is your body getting enough nutrients? This test gives you answers, plain and simple—and the motivation to make lasting changes.

• It’s always easier to take action when you can see the effect of your choices,

says Colin Robertson. By repeating the test every four months, you can easily track your progress.

Science. Transparency. Trust.

Every single test in our portfolio is analyzed anonymously and confidentially by Vitas AS, a world-leading independent laboratory in dried blood spot (DBS) testing. In 2023, Vitas reached a historic milestone when its database surpassed one million dried blood tests, making it the largest of its kind worldwide. Today, they analyze around 25,000 fatty acid profiles every month—clear proof that the global shift toward test-based health is well underway. For us, this data provides a solid scientific foundation to understand how modern lifestyles affect the body—and what can be done to reverse that trend.

Knowledge is power

The beauty of a test-based health journey lies in its personalization. It hands the power—and the responsibility—back to you. Instead of relying on gut feeling, generic advice, or fleeting trends, you learn how your body truly functions. This allows you to see exactly what you need to do—and you can track your progress in real time. Your health becomes measurable, motivating, and meaningful.

• Living healthy isn’t about doing everything perfectly—it’s about understanding what works for you, says Colin Robertson. Each body is unique, and listening to yours—especially your gut—is essential. Our health tests help you understand how your body responds to what you eat and how you live, empowering you to build better balance from the inside out.
