Becoming more aware of food
How your body reacts to foods, pollen and everyday substances is individual – from digestion to your general well-being. Click on an area to find out more.
Body awareness
A conscious sense of your body can help you notice personal connections between how you feel and your eating habits. That way you develop a finer feel for your own needs and sensations in everyday life.
For example:
- Food diary: note down your meals and how you feel afterwards.
- Spot patterns: look out for recurring sensations after certain foods.
- Use your result: compare your observations with your test result.
Mental approaches
Your eating behaviour can be closely linked to thoughts, emotions and habits. Noticing which factors influence your own food decisions can help you handle food and meals more mindfully and consciously.
For example:
- Eat consciously: calmly and without distraction.
- Observe stress: how does tension change the food you choose?
- Question routines: hunger, habit or emotion?
Nutrition & everyday life
A conscious diet can be built into your everyday life with simple methods. Through meal planning, deliberately observing your eating habits and small, lasting changes, you develop a sense of which foods might do you good.
For example:
- Variety: shop for a varied, seasonal mix.
- Step by step: try one change at a time.
- Support: if you have questions about your result, our nutritional consultation is here for you.

Frequently asked questions
Find answers on:
How do I send in my hair sample correctly?
Cut off 10–20 hairs as close to the scalp as possible and put them into a small paper or plastic bag. Stick the bag onto your submission form (the PDF from your order confirmation) at the marked spot. Please never put loose hairs into the envelope – inside the bag the sample stays protected during transport. Then fold the submission form, put it into a normal envelope and send it by post to the address given in the confirmation. At the same time, fill in the online questionnaire at fragebogen.medicross.com with your order number.
How many hairs are needed for the hair test?
We need 10 to 20 hairs for a reliable evaluation. The hairs should be freshly cut, clean, and dry. If you don't have enough head hair, you can also use body hair.
What hair length do I need for the test?
Hair length doesn't matter. Even very short hairs of just a few millimeters work, as long as you can gather the required 10–20 hairs. What counts is the number, not the length.
What do I do if I'm bald or have very little hair?
The test works perfectly fine even with a bald head, very thin hair, or bald patches. Use body hair instead — beard, chest, underarm, or leg hair work just as well as head hair. Combed-out or fallen hair without roots is also suitable, as long as you can gather the minimum of 10–20 hairs.
How does the Medicross hair analysis work?
You cut off 10–20 hairs, put them into a small paper or plastic bag and stick it onto the submission form from your order confirmation at the marked spot. You send both to us by post. At the same time, you fill in our online questionnaire with your personal order number. Your sample is then analysed and you receive your written evaluation as a PDF by email.
* Legal disclaimer
The products offered at www.medicross.com — such as „Intolerance Test“, „Micronutrient Test“, „Microplastic Test“ or „Heavy Metal Test“, along with their variants for pets — serve exclusively as individual, complementary wellness orientation. The names are used in a non-medical, everyday context. Our tests are based on alternative methods that do not involve any biochemical, molecular-biological, or cellular analysis. They have no medical purpose and are not equivalent to conventional medical lab tests or in-vitro diagnostics under EU Regulation (EU) 2017/746 (IVDR). The results are intended for subjective reflection on individual resonance patterns — in humans as well as animals — and do not replace medical or veterinary assessment. Our tests are expressly not intended to determine medically relevant parameters such as allergies or deficiency conditions. They constitute no diagnosis, contain no treatment recommendation, and are not suitable for the prevention, treatment, or monitoring of illnesses. We expressly point out that our tests and content: do not constitute or replace a medical diagnosis; are not intended to detect, treat, monitor, or prevent illnesses or health disorders; are not suitable for self-medication or therapy adjustment. None of the content represents a healing promise or efficacy claim. Diagnoses and treatment decisions may only be made by licensed medical doctors. For any health-related questions, qualified medical advice must always be sought. Every individual acts on their own responsibility. All product images and illustrations are symbolic and have no diagnostic or scientific value. The micronutrient analysis results in a need-percentage value, which is to be understood as a guide value. Expressly noted: this is not about deficiency symptoms. In intolerance tests, all parameters that do not react beyond a threshold value are hidden. The intolerance test does not include any test for allergies.
What approach does Medicross take?
Our approach is based on holistic and complementary ways of thinking, without making medical diagnoses or healing promises. Rather, we want to support you in shaping your lifestyle individually, consciously, and on your own terms. You can find more details in our Disclaimer*
¹ ² ³ Test extension, sources
Please note that substances marked with ¹ are optional and can be added to your evaluation for a surcharge. During checkout you have the option to select this add-on to include the desired substances in your personal analysis. ² Sources: Robert Koch Institute. (2016).

Available at: https://www.ndr.de/ratgeber/gesundheit/Vitamin-D-Mangel-Nahrungsergaenzungsmittel-koennen-Symptome-verhindern,vitamindmangel101.html. ³ Medicross customer survey 2024–2026, n = 106,092 participants from Germany, Austria, and Switzerland (women and men, voluntary self-disclosure).
Which foods are analyzed in the intolerance test?
Our intolerance test covers over 650 potential substances. These include commonly mentioned groups such as dairy products (lactose), fruit (fructose), grains (gluten), histamine-rich foods, as well as vegetables, nuts, spices, additives, and much more. You'll receive practical guidance on which substances might deserve special attention in your everyday life.
What is the difference between an allergy and an intolerance?
With an allergy, the immune system reacts to certain substances and can trigger stronger physical reactions. Individual food reactions typically don't involve the immune system and mostly show up in digestion or general physical well-being. Our test doesn't replace a medical diagnosis but can offer useful pointers for your everyday life.
Which symptoms indicate a food intolerance?
Some people notice reactions after eating certain foods — an unusual feeling in the stomach, bloating, nausea, diarrhea, or constipation. These can appear hours later, which makes it harder to identify the cause. In our survey, nearly 18% of participants personally reported intolerances — one of the more frequently mentioned topics.³
Is the Combo Test useful for athletes?
During phases of intense physical exertion, your individual need for vitamins, minerals, and trace elements can change. Nearly half of our survey participants regularly do endurance sports, and about a third also do strength training.³ The micronutrient analysis can give athletes impulses to reflect more consciously on their supply — complementing training and nutrition plans, but without replacing sports-medicine diagnostics.
Can I take the test during pregnancy or while breastfeeding?
For any questions about nutrition during this phase of life, please always consult your doctor, midwife, or a qualified nutritional advisor.
Do medications like cortisone or the pill affect my result?
Since our procedure isn't a biochemical blood measurement, you can usually take the test even while on medication — for example cortisone, the pill, antibiotics, antidepressants, painkillers, or thyroid medication. Please list your current medications and supplements in the online questionnaire — this helps us with the assessment. Any change to your medication should be discussed exclusively with your treating physician.
Can I take the hair test with dyed hair?
Yes — dyed, tinted, or chemically treated hair doesn't affect the result. You can send it in without any concerns. The same applies to hair after a perm, straightening, bleaching, or highlights. The only requirement is that it's clean and dry.
How long does it take to receive my test result?
Once your hair sample arrives with us, the evaluation usually takes around 18 business days. With the Express service, this time is shortened accordingly. You'll automatically receive an email as soon as your personal evaluation is ready.
In what format do I receive my test results?
You receive your evaluation as a PDF document by email. That way you can open it on your phone, tablet, or computer and print it yourself if you wish. There's no additional postal delivery.
How do I understand my evaluation? What do „Deficiency“ and „Need“ mean?
Your evaluation uses clear scales and plain terms: „Deficiency“ points to areas where our analysis shows a clearly pronounced pattern. „Need“ describes a more moderate signal — where it can be worth paying more conscious attention to certain food groups or routines in your daily life. The percentage values next to them express the intensity of the individual resonance. Both terms are meant as an impulse for reflection and don't replace a medical diagnosis.
Who can I contact with questions about my evaluation?
Our team of nutritional scientists is available by email or phone. You can also book a consultation directly if you'd like to go through your results together.
How do I order the Combo Test?
Choose the Combo Test in our online shop, add it to your cart, and follow the checkout process. After completion, you'll receive a confirmation email with your personal submission sheet to print yourself and all further information.
Do I receive a test kit by mail?
No, we deliberately do not ship a test kit. Instead, after your order you receive your personal submission form as a PDF by email to print out yourself. You put your hair sample into a small paper or plastic bag and stick it onto the printed submission form at the marked spot. You put both into a normal envelope and send it to us. This saves shipping time and packaging waste, and speeds up the process for you.
I haven't received an order confirmation — what should I do?
Depending on the payment method, it can take up to 24 hours for the confirmation with the submission sheet to reach you. Please also check your spam or promotions folder first. If after 24 hours you still haven't found it, write to us at info@medicross.com — we'll send you the confirmation manually.
Can I use the Combo Test for several people?
Each Combo Test is designed for one person, since the evaluation is created individually. If you'd like to test a partner, children, or other people, please order a separate test per person.
Can I revoke or cancel my order?
You have a 14-day right of withdrawal after your order — but only as long as you haven't downloaded your submission sheet yet. With the download of the submission sheet, the service begins and the right of withdrawal expires early. Once the 14-day period has passed or the submission sheet has already been downloaded, cancellation is no longer possible. As long as both conditions are met, simply send us an email with your order number to info@medicross.com.
