Get clarity with an at-home vitamin and mineral test
ca. 21 Minuten
Do you often feel tired, unfocused, or simply not at your best, even though you take care of your health? A targeted vitamin and mineral test gives you scientifically backed answers about what your body is really lacking. Instead of groping in the dark, you get clear insights into your nutrient profile and can take targeted steps to optimize your health.
Why a test is the first step toward greater well-being
Maybe you know the feeling: You diligently take your supplements, try the latest superfood bowl, and make sure to get enough sleep—and still you lack energy. This vague feeling that something isn’t right is familiar to many health-conscious people. Often, the reason is that we guess instead of knowing.
We reach for vitamin D capsules in winter or iron supplements when we feel tired, without a data-based foundation for that decision. This is exactly where a professional vitamin and mineral test comes in. It’s the smart first step toward replacing assumptions with facts.
From guessing to knowing: The power of data
A blood test gives you an accurate picture of your current nutrient status. Think of it as a detailed map of your body: Instead of wandering around aimlessly, you can see exactly where action is needed and where your nutritional needs are already being met.
This precise analysis helps you take targeted action against symptoms such as low energy, digestive problems, or skin irritation. You not only save money on unnecessary supplements, but also invest in exactly what your body really needs.
A test takes you from general health awareness to personalized health optimization. You stop following trends and start listening to your body’s individual signals—backed by scientific data.
This clarity is especially important because many people tend to self-medicate. Despite generally good healthcare in Germany, according to a BfR survey, over 75 percent of the population take supplements, but an actual deficiency has been diagnosed in only 16 percent. This shows how many people take pills unnecessarily instead of getting to the root causes of their symptoms. You can learn more about these findings from the Verbraucherzentrale.
Your body, your health: Take charge
Choosing to get tested is an act of taking responsibility for yourself. You take control of your health and make informed decisions. With a mybody® at-home test, you can easily gain these valuable insights from home—without booking an appointment or facing long waits at the doctor’s office.
For women in particular, a test like this offers deeper insights. With mybody®, you gain in-depth insights into your women's health—from hormones and nutrients to your metabolism. This helps you understand what your body really needs to feel good, balanced, and healthy in everyday life.

Understanding the Most Important Nutrient Markers in Your Blood
A lab report full of names and numbers can seem quite intimidating at first. But don't worry, it's much easier than you think to decipher the key values. Think of them as the leading players in your very own health movie: each has an important role, and only how they work together determines how good you feel in the end.
A vitamin and mineral test is, so to speak, the translator that makes your body's language understandable. It shows you in black and white where you may be missing important building blocks and where you're already well supplied. Let's take a closer look at the most important of these leading players together.
The Sunshine Vitamins and Energy Boosters
Two of the best-known and most important vitamins are vitamin D and vitamin B12. They have a direct impact on your energy, mood, and immune defenses. That's exactly why they play a central role in almost every good nutrient test.
-
Vitamin D – Your Immune System Booster
Think of vitamin D as the conductor of your immune system. It helps regulate your body's defense responses and is essential for calcium absorption, which in turn keeps your bones strong. A deficiency, especially common during the dark winter months, can show up as frequent infections, low mood, and general fatigue. Extremely many people in Germany don't get enough vitamin D, making this value incredibly important. -
Vitamin B12 – Fuel for Your Cells
Without vitamin B12, practically nothing happens in your energy metabolism. It is essential for the production of red blood cells, which transport oxygen throughout your body, and for the functioning of your nerves. Do you often feel tired, unfocused, and low on energy? A B12 deficiency could be the cause, especially if you eat a vegan or vegetarian diet, since this vitamin is found almost exclusively in animal products.
The essential minerals
Alongside vitamins, there are minerals—the unsung heroes working behind the scenes. They are involved in hundreds of processes, from muscle contraction to wound healing. A deficiency can have far-reaching consequences.
Some of these minerals are particularly important and should therefore be checked regularly. Keeping them in balance is absolutely essential to your daily well-being.
A single value tells only half the story. Only by looking at how nutrients work together can you get a clear picture of your health. Magnesium, for example, improves the activation of vitamin D, while vitamin C optimizes iron absorption.
This complex network shows why a comprehensive test is so valuable. It not only detects individual deficiencies, but also possible imbalances that may be affecting your health without you realizing it.
Iron, zinc, and magnesium in focus
These three minerals are true all-rounders and are central to your performance.
Iron (ferritin)
Fatigue is one of the most common symptoms that prompts people to get tested. And very often, iron deficiency is behind it. Your ferritin level reveals how full your iron stores are. Iron is key to transporting oxygen in the blood, so depleted stores literally leave you short of breath. Women of childbearing age, athletes, and people who follow a plant-based diet should pay particularly close attention to this level.
Zinc
This trace element is a true all-rounder for your health. Zinc not only strengthens your immune system, but is also essential for healthy skin, strong hair, and good wound healing. If you often struggle with blemishes or small wounds that heal slowly, a zinc deficiency could be the cause.
Magnesium
Magnesium is the relaxation mineral for your muscles and nerves. It not only helps prevent muscle cramps, but is also essential for a restful night's sleep. Do you often feel stressed, sleep poorly, or suffer from tension? Checking your magnesium levels can be very revealing.
Understanding these key markers is the first crucial step toward regaining control of your health. Each individual value provides an important piece of the puzzle that is your unique nutrient profile.

Which at-home test is right for you
So, you’ve decided to get to the bottom of your nutrient levels - great! But now you’re faced with the next question: Which vitamin and mineral test is right for you? The world of at-home tests is vast, and the methods differ. To get truly reliable and informative results, it’s important to understand the differences.
The most common methods analyze blood, serum, or urine. Each method has its own strengths and is better suited to certain questions than others. After all, your goal is to get a clear picture of your nutrient levels. That’s why choosing the right testing method is the crucial first step on your path to greater well-being.
Fingertip blood sample: the smart at-home solution
When you think of a blood test, you probably immediately picture the classic needle in your arm at the doctor’s office. But for many analyses, there’s now a much simpler and more convenient alternative: a capillary blood sample from your fingertip, also known as a “Dried Blood Spot” (DBS).
This modern, scientifically validated method is exactly what mybody® uses for tests you can easily do at home. With a small prick to your fingertip, you collect a few drops of blood on a special test card. The sample is extremely stable and can be safely mailed to our lab.
The key advantage: You have complete flexibility and don’t have to work around doctor’s appointments or crowded waiting rooms. Collecting the sample takes just a few minutes and fits perfectly into your daily routine, while the analysis quality in the lab is identical to that of a venous sample.
This method is not only super practical, but also extremely accurate for measuring a wide range of vitamins, minerals, and other important biomarkers.
This infographic can help you decide which markers might be relevant to you, depending on how you feel.
The decision tree shows how symptoms like fatigue or stress can point to specific nutrient deficiencies and guides you to the right markers.
Serum and urine tests: when are they useful?
In addition to analyzing whole blood, there are other specialized testing methods used for specific purposes. However, how informative they are depends largely on exactly what you want to know.
-
Serum tests
Serum is the liquid part of blood after the blood cells have been removed. A serum test provides a very accurate snapshot of the concentration of nutrients freely circulating in the blood. It’s ideal for determining acute conditions and the immediately available levels of many vitamins and minerals. -
Urine tests
Urine tests are often used to measure what the body excretes. They can provide insights into how the body processes certain metabolic products. However, they are often less informative than blood tests for checking overall nutrient status. That’s because urine concentration depends heavily on how much you drink and how well your kidneys are working.
For a comprehensive and reliable analysis of your vitamin and mineral levels, a fingertip blood test like the one offered by mybody® is the best choice in most cases. It combines high accuracy with maximum convenience.
If you want a truly complete picture of your nutrient levels, the mybody®x Complete Nutrient & Mineral Check is an excellent option for gaining in-depth insights. This helps you make an informed decision about your health.

How to decipher your results and put them to use
You’re holding your mybody® results report—a pivotal moment on your journey to better health. But what do all these numbers and charts actually mean for you? Think of this section as your personal guide. It will help you turn raw data into valuable, actionable insights for everyday life.
Your report is much more than just a list of values. It’s the key to finally understanding your body’s signals and taking targeted action. Let’s look together at how to read and interpret your results correctly, and then put them into practice.
Reference ranges and your personal comfort zone
Your report lists a so-called reference range for each value. This range indicates which values are considered “normal” for a large proportion of the healthy population. It’s important to understand that this is a statistical average—and not necessarily your personal optimal state.
Your individual needs can vary considerably from this standard depending on your lifestyle, age, gender, and health goals. For example, an active female athlete often needs more iron than someone with a less active lifestyle, even if both have values within the general reference range.
Your goal should be not just to fall somewhere within the reference range, but to reach your personal optimal range. That’s where you feel most energetic, fit, and comfortable. mybody® helps you define this individual target range for yourself.
From results to action: Real-world case studies
Theory is great, but what matters is putting it into practice. So let’s look at how you can turn typical results from a vitamin and mineral test into concrete actions.
Case study 1: Low vitamin D levels in winter
Your test shows a vitamin D level at the lower end of the reference range—a classic scenario during the darker months.
- Nutrition: Consciously include vitamin D-rich foods like fatty fish (salmon, herring), egg yolks, and mushrooms in your diet.
- Lifestyle: Take every opportunity to get sunlight. Even a short walk during your lunch break can help boost your body's own production.
- Supplementation: In the case of a significant deficiency, targeted supplementation is often the most effective approach. Your mybody® report gives you a specific dosage recommendation that you can discuss with your doctor.
Case study 2: Depleted iron stores (low ferritin) in a female athlete
You exercise a lot and often feel tired. Your ferritin level is low, which suggests your iron stores are depleted.
- Diet: Choose iron-rich foods. Always combine plant-based sources such as lentils, spinach or oatmeal with vitamin C (e.g., bell pepper, orange juice) to maximize absorption. Lean red meat is also an excellent source.
- Timing: Avoid coffee or black tea with meals. The tannins they contain can inhibit iron absorption.
- Medical evaluation: A low ferritin level should always be evaluated by a doctor, especially if symptoms persist. This can rule out other causes and help determine the right strategy for replenishing your stores.
These examples show how small, targeted adjustments can often make a big difference.
When supplements make sense - and when they don't
Targeted supplementation can be extremely effective in correcting a confirmed deficiency. But it is never a substitute for a balanced diet. The trend toward taking dietary supplements continues unabated. Magnesium, zinc and calcium were the top 3 most popular minerals in Germany in 2023. This highlights growing awareness, but also the need to avoid supplementing blindly and confirm your needs with a test. Learn more about the use of minerals in Germany on Statista.com.
A vitamin and mineral test gives you the confidence to supplement only what your body really needs and avoid overdosing.
Nutrient-rich foods for common deficiencies
Sometimes all it takes is a smart adjustment to your diet to make up for or prevent a deficiency. This table gives you specific examples of foods you can eat to increase your intake of important vitamins and minerals.
| Nutrient | Top food sources |
|---|---|
| Vitamin D | Salmon, herring, mackerel, egg yolk, foods fortified with vitamin D |
| Vitamin B12 | Meat, fish, eggs, dairy products, fortified plant-based alternatives |
| Iron (ferritin) | Red meat, lentils, chickpeas, spinach, pumpkin seeds, quinoa |
| Magnesium | Almonds, cashews, spinach, dark chocolate, bananas, whole grains |
| Zinc | Oysters, beef, pumpkin seeds, lentils, oats, cashews |
| Selenium | Brazil nuts (Note: 1-2 a day is enough!), tuna, sardines, eggs, sunflower seeds |
As you can see, nature often has the best solutions ready to hand. Choosing your foods mindfully is the first and most important step toward optimal nutrient levels.
How to prepare for a conversation with your doctor
Your mybody® results report is an excellent basis for an informed conversation with your doctor or therapist. It allows you to ask targeted questions and plan the next steps together.
Before your appointment, make a note of any symptoms you have and any questions prompted by your report. This will help you go from being a passive patient to an active partner in your own health.
Still have questions? Here are the answers.
You now have a good overview of how a vitamin and mineral test can pave the way to greater well-being. Still, before your first analysis, a few final, practical questions often come up. We’ll answer them here so you can get started feeling confident and reassured.
Here you’ll find quick, honest answers to clear up any lingering doubts.
How often should I take a vitamin and mineral test?
The ideal frequency depends entirely on you, your lifestyle, and how you’re feeling. There’s no one-size-fits-all rule, but there is a good rule of thumb.
We recommend a check every three to six months as a solid baseline. Think of it as a regular health check-up, but focused specifically on your micronutrients. This helps you keep track of everything and spot long-term trends before they become a problem.
However, in some situations, it makes perfect sense to test more often:
- When changing your diet: If, for example, you switch to a vegan or vegetarian diet, taking a test after 3 to 6 months is a great idea. This helps ensure that you’re getting enough critical nutrients like vitamin B12 and iron.
- If you train intensively: As an athlete, your body uses more—especially minerals such as magnesium and zinc. Regular checkups can help you optimize your performance and prevent deficiencies.
- To monitor treatment: If you’re addressing a known deficiency with supplements, a follow-up test after a few months is essential. It’s the only way to see whether your measures are working and whether the dosage is still right.
- If you’re under constant stress or have unclear symptoms: Do you feel constantly tired, stressed, or simply not at your best? More frequent testing can help get to the root of the cause.
Don’t worry, you don’t have to decide this yourself. Based on your results, your mybody® report always includes a personalized recommendation on when it makes the most sense for you to take your next test.
Are home tests just as accurate as tests at the doctor’s office?
Absolutely. This is one of the most important questions, and the answer is a clear yes. The accuracy of a test doesn’t depend on where you collect your sample—whether at home at the kitchen table or at a clinic—but on where and how it is analyzed.
mybody® sends your sample exclusively to ISO-certified German specialist laboratories. These are exactly the same highly specialized labs that doctors, hospitals, and other medical facilities work with. The analysis methods are identical and follow the highest scientific standards.
Taking blood from your fingertip (the so-called dried blood spot method) is a well-established, scientifically recognized method that has been used for decades. When performed correctly, it delivers highly accurate results. To make sure everything goes smoothly, each test kit includes a simple, illustrated guide that walks you safely through the process step by step.
What should I keep in mind before collecting my sample?
To make sure your results are as meaningful and accurate as possible, there are a few simple guidelines to follow before collecting your sample.
- Fast: Ideally, collect your sample in the morning, right after getting up. You should have eaten nothing for at least 8 hours beforehand and drunk only water or unsweetened tea.
- Pause supplements: Some supplements, especially high-dose biotin (vitamin B7), can skew the results of certain tests. We therefore recommend stopping supplements 24 to 72 hours before collecting your sample.
- Wash your hands: This is a small but important step. Before collecting your sample, wash your hands thoroughly with warm water and soap. This not only cleans the puncture site, but also stimulates circulation and makes collecting the sample much easier.
Every mybody® test kit comes with easy-to-follow step-by-step instructions. So you don’t have to worry about doing anything wrong.
Who can benefit most from a vitamin and mineral test?
A test is valuable for anyone who cares about their health and no longer wants to guess, but finally wants to know what’s really going on in their body. However, there are certain groups for whom the insights gained can be a real game-changer.
A test turns general health concerns into personal, tangible facts. It is the foundation for any targeted improvement to your diet and lifestyle.
Those who can benefit most:
- People with unexplained symptoms: If you suffer from constant fatigue, digestive problems, hair loss, difficulty concentrating, or skin irritation.
- People following specific diets: Especially those eating vegan, vegetarian, or very restrictive diets, to identify nutritional gaps early.
- Athletes: To meet increased nutrient needs, speed up recovery, and improve performance.
- Women who want to conceive or experience hormonal fluctuations: To ensure the body is optimally prepared for pregnancy or to better understand hormone-related symptoms.
- Anyone who wants to take preventive action: To proactively take charge of their health and prevent deficiencies before they lead to noticeable problems.
The huge interest in this topic is also reflected in the market: In Germany, the market for vitamins and dietary supplements reached an impressive 1.78 billion euros in 2023. This figure shows just how important it has become for people to manage their nutrient intake themselves. Learn more about this market trend at Mintel.com.
