Frequently asked questions about metabolism and the DNA Metabolism Test

  • Why test the vitamin metabolism and nutrient requirements?

    People have varying needs for nutrients – for example, some people absorb larger amounts of vitamins. Others absorb particular nutrients less efficiently from food. Others tend to be at risk of disease, which they can counteract with an adequate intake of minerals and vitamins.

    Which nutrients your body particularly needs is also determined by your genetics. If you know your genetic predisposition and your metabolism better, you can ensure you receive a sufficient supply of the required nutrients - for example, with nutrient deficiency tests, a targeted change in diet or nutritional supplements.

    The cerascreen® DNA Vitamin Metabolism Test provides you with information on how your DNA determines your nutrient requirements and what you should focus on when it comes to your daily diet.

    Please note: If the DNA analysis shows an increased risk of a nutrient deficiency or disease predisposition, it does not automatically mean that you will develop these! These genetic predispositions are probabilities and indicate the possibility of certain health problems emerging. Moreover, the recommendations regarding a balanced diet that meets needs are also useful for people who do not display these predispositions.

  • Who should take the DNA Vitamin Metabolism Test?

    The DNA Metabolism Test is an excellent choice for anybody who wants to ensure an optimal intake of vitamins, minerals and other nutrients. The information gained from the DNA Vitamin Metabolism Test helps you to identify crucial nutrients and to take targeted countermeasures through nutrient deficiency tests, nutrition and supplements.

    For some people, these insights are particularly interesting: lifestyle, illness and diets such as veganism can influence how high your nutritional needs are for certain nutrients. If you already have special requirements regarding your vitamin and mineral intake, it can be useful to learn about your genetic preconditions for nutrient needs as well.

  • How does the DNA Vitamin Metabolism Test work?

    For the DNA Vitamin Metabolism Test, take three small saliva samples from the oral muscosa – that is, the inside of your mouth. Three cotton swabs are included in the test kit to take these samples; place these in the test tubes after use. You can then send the saliva samples back to us to be analysed in the specialist medical laboratory.

    The specialised laboratory performs complex DNA sequencing. This means that the components of the DNA can be analysed in great detail. How long the analysis takes depends on the quality of the sample provided – sometimes, the laboratory has to repeat the analysis several times. Therefore, in individual cases, it can take up to four weeks until you receive the test result.

  • What do I need to consider when I take the DNA Vitamin Metabolism Test?

    The higher the quality of the sample, the faster and easier it is for the laboratory to analyse it. You can help by observing the following guidelines for collecting samples:

    • You should not eat or drink anything for at least half an hour before taking the sample.
    • Do not brush your teeth or use mouthwash during this time.
    • Do not smoke in the half hour before the test is done.
    • The sample must be stored in a dry place for 24 hours before it is sent off. During this time, the specimen dries across the aeration membrane at the bottom of the test tube.
  • What does the results report tell me?

    Based on the 26 genes analysed, the results report provides you with information about genetic characteristics with regard to your requirements concerning the six nutrient groups. In each case, you will receive a possible interpretation of whether your gene variants require a normal or increased dosage of vitamins and nutrients.

    The levels of the following nutrients are analysed:

    • Antioxidants
    • Vitamin B12 and folic acid
    • Vitamin C
    • Vitamin D and calcium
    • Iron
    • Unsaturated fatty acids
  • What kind of recommendations will I receive?

    In each case, you will receive specific recommendations on how to consume the appropriate dosage of various vitamins and nutrients – depending on how well your metabolism works.

    We will also provide you with general tips for a healthy diet that you can use in your everyday life.

  • Why do I need antioxidants?

    You may need to increase your antioxidants intake if your body is prone to oxidative stress. Oxidative stress occurs when there are too many free radicals in the body – oxygen molecules that can damage the genetic material of cells. Antioxidants are the antagonists of free radicals and can curb their effects.

    You can cater to this requirement through your daily diet: we take in antioxidants through a range of nutrients, including phytochemicals, zinc, selenium, iodine and vitamins A, B2, C and E.

  • Why do I need vitamin C?

    Vitamin C has an antioxidant effect and is involved in numerous important processes in the body – for example, in immune defence, in the formation of collagen and hormones and in the transport of fatty acids.

    Although a vitamin C deficiency is rare in the Western world today, it can have serious consequences, such as impaired wound healing, anaemia and bleeding gums.

    If your genes indicate you need more of this vitamin, it makes sense to pay extra attention to the intake of vitamin C-rich foods. These include many berries, citrus fruits, peppers and green vegetables, such as kale and spinach.

  • Why do I need vitamin B12 and folic acid?

    A gene variant can increase the risk of elevated levels of the amino acid homocysteine in the body. This, in turn, can increase the likelihood of atherosclerosis and other circulatory disorders.

    You can counteract this by ensuring an adequate supply of folic acid and vitamin B12. This is because the two nutrients regulate the production of homocysteine and counteract an excess of it.

    This is particularly relevant for people who are vegetarian or vegan because vitamin B12 is found almost exclusively in animal products. Vegans should therefore regularly check their vitamin and nutrient intake levels and take vitamin B12 supplements.

  • Why do I need vitamin D and calcium?

    Vitamin D and calcium are essential for healthy bones. Vitamin D controls calcium absorption in the intestine. Calcium, in turn, is absorbed into the bones and makes them stronger.

    That is why vitamin D deficiency has been shown to have a major impact on the risk of developing diseases such as osteoporosis (bone loss) and osteomalacia (softening of the bones), among others.

    If your gene variants indicate an increased risk of bone loss, it is therefore worth checking your vitamin D and calcium levels. Many people in Europe lack vitamin D, which our bodies produce with the help of sunlight.

  • Why do I need iron?

    Iron is crucial for the production ofblood cells. Your body needs the trace element to transport the blood pigment haemoglobin and to supply the entire body with oxygen. An iron deficiency usually leads to anaemia in the long run.

    The iron your body can best absorb comes from animal foods, such as liver, red meat, herring and chicken eggs.

    You should be aware of possibly needing to increase your iron intake if you are a vegetarian or vegan. To ensure that you can optimally absorb iron from plant-based foods, such as whole grains, legumes and tofu, you should combine them with a diet rich in vitamin C.

  • Why do I need unsaturated fatty acids?

    They are considered the healthy fats – the unsaturated fatty acids and especially the omega-3 fatty acids. Among other things, omega 3 counteracts inflammation, improves blood circulation and has a positive influence on cholesterol levels.

    In today’s Western diet, however, many people consume very insufficient amounts of omega-3 fatty acids and too many of the unhealthy saturated and trans-fatty acids.

    Omega 3 is mainly found in fatty fish and some vegetable oils, such as rapeseed, walnut and linseed oil. If you don’t eat fish, it may be worthwhile turning to omega 3 supplements – especially if an analysis of your gene variants reveals a need to increase your omega 3 intake.

  • Who is the test not suitable for?

    The DNA Vitamin Metabolism Test is not suitable for or is only suitable, to a limited extent, for certain groups of people:

    People with infectious diseases must not take the DNA Vitamin Metabolism Test .

    Pregnant and breastfeeding women should only use the DNA Vitamin Metabolism Test under medical supervision. The reference values and recommendations do not apply to them, so they should ask their doctor for recommendations regarding the test results.

    The DNA Vitamin Metabolism Test is not suitable for children under 18 years of age.

    The test is not meant to diagnose diseases. For example, if you suffer from severe pain or suspect a deficiency, consult a doctor.
