Vitamin D Test - 4 Pack

Measure vitamin d levels (25-OH-D3) 

Worldwide, an estimated one billion people have inadequate levels of vitamin D in their blood, and deficiencies can be found in all ethnicities and age groups’ (Harvard School of Public Health, 2012). It is important to know your vitamin D level and supplement according to your individual needs.

Strong bones and muscles, mental fitness, prevention of osteoporosis and better athletic performance are just a few of the benefits that are linked to healthy vitamin D levels in countless scientific studies. Young adults, elderly people and women all especially need to keep their vitamin D level in mind because they are at a higher risk.

Unfortunately, a vitamin D deficiency can not be ‘tasted’ or ‘felt’. Therefore, it is important to test for a vitamin d deficiency regularly.

With the cerascreen® Vitamin D Test, a diagnostic send-in test that you can use at home, you can determine your blood concentration of vitamin D and to monitor the level of 25-OH vitamin D in your blood. The Vitamin D Test includes a free return envelope and analysis in our diagnostics laboratory as well as a detailed results report.

Information about the Vitamin D Test

Advantages of the Vitamin D Test

Too little vitamin D is detrimental to health. A vitamin d deficiency can lead to symptoms such as fatigue, headaches and muscle weakness. Sometimes it goes unnoticed – and yet in the long run, it increases the risk of osteoporosis, bone fractures and other diseases.

Test yourself at home and save time. You don’t have to spend any time in waiting rooms at your doctor’s surgery. Instead, take your health into your own hands. You can take the sample comfortably and discreetly at home.

It’s easy to look after your health. Do you suspect a vitamin d deficiency? Then it is easy to optimise your vitamin D levels with our recommendations. This way, you can keep your levels optimal all year round and improve your health, well-being and performance on your own.

Benefit from our expertise: cerascreen® is the market leader for medical sampling and submission kits in Europe, with eight years of experience in test development and analysis. We have developed more than 50 approved send-in test kits (medical devices), evaluated 250,000 samples and serve 19 countries. 

Vitamin D is a year-round issue

Due to diet and lack of sunlight, vitamin D concentration in many people is often less than 31 nanograms per millilitre (ng/ml) and thus below the minimum concentration recommended by physicians. On the other hand, experts in orthomolecular medicine recommend a healthy level of between 40 and 60 nanograms per millilitre as the target for optimal and preventive care.

One should check their vitamin D level several times a year!

Quickly and easily determine if and to what extent you lack the essential vitamin D!

The Cerascreen Vitamin D Test makes determining your vitamin D levels fast and easy. You send a few drops of blood from your fingertip to our specialised laboratory, where we take care of the professional analysis and individual evaluation. Based on the test results, our nutrition experts will determine your personal vitamin D supplementation plan.

Vitamin D is generally considered a feel-good vitamin and supports more than 30 important bodily functions. But since vitamin D is primarily formed by the skin’s direct exposure to sunshine, the vast majority of people are not sufficiently supplied with vitamin D! Additionally, many people have a nutritional condition that prevents them from absorbing and storing vitamin D properly.

Results report of the Vitamin D Test

As soon as your sample has been analysed, you will receive your results report via the My cerascreen® app or your user account on our website. You can easily view the report on your smartphone, tablet or computer and print it out, if required.

Find out whether your vitamin D levels are within the optimal range in the laboratory analysis. Learn how to improve your vitamin D levels through concrete recommendations for action. You will also receive comprehensive health information, in which we go into detail about the functions of vitamin D and explain what it does in our bodies.

FAQs about the Vitamin D Test

  • Why take the Vitamin D Test?

    Vitamin D deficiency is widespread in the Western world. What is the reason for this? Many people simply don’t get enough exposure to sunlight. In addition, our geographic locations mean we receive too little sunlight to fill our vitamin D reserves.

    A vitamin D deficiency causes symptoms such as fatigue, digestive problems and headaches. In addition, a deficiency can be detrimental to our health in the long term. Among other things, it increases the risk of bone fractures and osteoporosis. In scientific studies, people with health conditions such as cardiovascular disease, diabetes, depression and high blood pressure also often have a vitamin D deficiency too. Researchers suspect that too little vitamin D could increase the risk of these diseases.

    It is therefore worthwhile for most people in central and northern Europe to check their vitamin D levels and optimise them if necessary. With the Vitamin D Test from cerascreen®, you can determine your levels – from home, anonymously and without waiting at the doctor’s surgery.

  • Who should take the Vitamin D Test?

    A Vitamin D Test is worthwhile for almost everyone in central and northern Europe. In these latitudes, it is difficult to produce enough vitamin D for the whole year through exposure to the sun.

    There are, however, some risk groups. The test is particularly suitable for you if the following applies to you:

    –You suffer from symptoms such as chronic fatigue, headaches, muscle and bone pain or constant infections

    –You spend little time in sunlight

    –You suffer from intestinal diseases such as Crohn’s disease or coeliac disease

    –You have an increased risk of osteoporosis

    –You are 60 years old or older

    –You have a dark skin type, so your skin needs more UV radiation to produce vitamin D

  • How does the Vitamin D Test work?

    For the Vitamin D Test, take a few drops of blood from your fingertip with a lancet. Then, send your blood sample by return envelope to our specialised laboratory that measures the concentration of 25-(OH)-D in your blood serum.

  • What does the results report tell me?

    The Vitamin D Test tells you the concentration of 25-(OH)-D in your blood, in nanograms per millilitre. You get a classification, in which range your value is. Here are some examples of the ranges that many of the results fall into:

    –11 to 30 nanograms per millilitre: long-term vitamin D deficiency

    –31 to 40 nanograms per millilitre: sufficient vitamin D levels

    –41 to 60 nanograms per millilitre: good and vitamin D levels

    The results report also gives you instructions on how to bring your levels into a healthy range with the help of vitamin D supplements. We give recommendations on how long you should take supplements for and which dosage we would recommend – as well as on how to keep your vitamin D levels at a healthy level for the long term.

  • How do I know if I am deficient in vitamin D?

    Vitamin D deficiency symptoms are usually rather generic and include:

    – Tiredness, fatigue and low mood

    – Sleeping problems

    – Headaches and backaches

    – Muscle weakness and musculoskeletal pain

    – Increased susceptibility to infections

    It is difficult to sense a deficiency – so to speak – and for this very reason, it often makes sense to check your levels with a vitamin D test. If you know your vitamin D levels, you can optimise them with vitamin D supplements, for example.

  • Why do I need vitamin D?

    Vitamin D is both a vitamin and a hormone. It carries out numerous important functions and metabolic processes in our body, including:

    – Formation of muscle fibres and muscle cells

    – Skeletal structure and bone mineralisation

    – Absorption of calcium and phosphate in the intestine

    – Function of the heart muscle

    – Strengthening the immune system

  • What are good sources of vitamin D?

    The human body can produce vitamin D itself, but it needs UV-B radiation from the sun to do so. More precisely, we produce the prohormone cholecalciferol (vitamin D3) with the help of sunlight, which the body converts into the active form of vitamin D (25-OH vitamin D3).

    Experts recommend sunbathing for 5 to 25 minutes a day in such a way that the sun’s rays hit about a quarter of the skin’s surface – for example, your face, hands and parts of the arms and legs. But you should be careful – too much UV radiation increases the risk of skin cancer!

    The optimal time in the sun depends on the following factors:

    – Skin type: Darker pigmented people need more sun to generate enough vitamin D

    – Season: In winter, there is less UVB radiation and so the body produces less vitamin D.

    – Time of day: People who are in the sun at midday produce more vitamin D because UVB radiation is highest then.

    Through food, we can cover at most 10 to 20 per cent of our daily vitamin D requirement – for example, with fatty fish such as salmon, herring and mackerel, as well as with liver and egg yolk. The sun is therefore paramount for a sufficient supply of vitamin D.

  • Which foods contain vitamin D?

    Vitamin D3, which our body can absorb well from food, is mainly found in animal products, especially in:

    – Fatty fish such as salmon, herring and mackerel

    – Margarine and butter

    – Liver

    – Egg yolk and milk

    – Plant-based foods such as mushrooms and avocados also contain vitamin D – but in a form that your body cannot absorb effectively

  • How much vitamin D does my body need?

    For a long time, it was considered that we are sufficiently supplied with vitamin D from 30 nanograms per millilitre of blood (ng/ml). However, some doctors are of the opinion that we only fully benefit from the positive effect of the sunshine vitamin at an intake of 40 to 60 ng/ml.

    Since we spend a lot of time indoors in the Western world and sometimes have few hours of sunshine a year, many of us cannot produce enough vitamin D, even in summer. Most people’s vitamin D levels are therefore below the norm all year round.

  • Do I only need vitamin D supplements in winter?

    In winter, most people in central and northern Europe have lower vitamin D levels. Our body can hardly produce vitamin D because of the low levels of sunlight. That is why it is often helpful to counteract this with supplements.

    However, many people do not have sufficient vitamin D levels – even in summer. This is due, among other things, to the amount of time we spend indoors and to the suncreams we use that protect us from UV radiation. So for some, supplements can be useful in summer too. It is simply best to find out your vitamin D levels – for example, by taking a test – and deciding on supplementation depending on your results.

  • Can you overdose on vitamin D?

    Your body cannot simply excrete vitamin D through urine like many other vitamins. If your vitamin D levels are already within a healthy range and yet you take a very high dose of vitamin D, your vitamin D levels will be too high. Possible consequences of a vitamin D overdose include:

    – Nausea and vomiting

    – Cardiac arrhythmia

    – Disturbances of consciousness

    – Long-term weight loss, kidney stones and organ damage

  • For whom is the Vitamin D Test not intended?

    The Vitamin D Blood Test is not or only partially suitable for certain groups of people:

    – People with infectious diseases, like hepatitis and HIV, may not use the Vitamin D Test.

    – People with haemophilia should not take the test.

    – Pregnant and breastfeeding women should only take the Vitamin D Test under medical supervision. The given reference ranges and recommendations do not apply to people in this group; consult your medical professional for advice concerning your test results.

    – The Vitamin D Blood Test is not intended for children under 18 years of age.

    The test is not intended for diagnosing illnesses or disease. For example, if you suffer from depression or are in physical pain, consult a doctor.
