Why test vitamin D?
Vitamin D is considered a feel-good vitamin and is particularly important for your bones, your immune system and your feelings of happiness. However, around 80% of people suffer from a vitamin D deficiency. However, a precautionary intake of vitamin D preparations is not recommended, as an oversupply of vitamin D can have a toxic effect. It is therefore all the more important to check your vitamin D status regularly. Only then can you give your body what it really needs. The vitamin d quick test from kiweno shows you immediately how well you are supplied with vitamin D. This knowledge helps you to increase your well-being, prevent seasonal mood swings and strengthen your body from within.

Why use the kiweno rapid self-test?
This innovative vitamin d rapid self-test gives you exact results within minutes. The rapid test is used to determine your vitamin D concentration in the blood. Our kiweno vitamin d app guides you through the entire test procedure: For this we need a few drops of blood, which are applied to the test cassette and then evaluated by your smartphone. The concentration of vitamin D (25-OH-D) in your blood is measured, which causes the test strip to react in colour so that the smartphone can display the result.

Is my smartphone suitable for this test?
On kiweno.com/vitd-schnelltest you will find all models and systems, which are compatible with the speed test.

I have checked my Vitamin D levels. What do the results mean?

When you check your vitamin D levels, it is important to understand what the results mean and which measures you should possibly take. From the results of this bloodtest, you can determine if you are getting the right amount of vitamin D, or too little or too much. This helps in deciding which supplement you should take. 

When you get your test results, you will receive a number in ng/ml, for example 50 ng/ml. These are the measures used by the health experts in the United States. In all other countries around the world, the results would be presented as nmol/l.


Meaning of your vitamin D level in ng/ml     and nmol/l
High values 60-90    150-225
Normal values 35-60    80-150
Low values 20-35     50-80
Vitamin-D-deficient under 20    under 50

Repeat your test regularly

After treating your deficiency, it is advisable to check your levels with some time in between. Sometimes the vitamin D levels can sink again over time, because of permanent life circumstances which make you deficient. A lifelong intake of vitamin D supplements might be necessary for you.

Vitamin D can be made by our bodies, when our skin gets exposed to enough sunlight. However, living in Central and Northern Europe, we are not getting enough sun to cover our bodies needs. Furthermore, certain Western lifestyles (being indoors a lot) and food intake low in vitamine D ( low fat and very little oily fish), can contribute to a deficiency quite easily. The consequence is, that many people have an undiagnosed vitamin D deficiency.


Vitamin D is the vitamin for healhty bones

This statement is true, because vitamin D is responsible for the absorption of calcium in your intestines, and for the storage of calcium in your body (skeleton).  However it would be selling the vitamin short, to say it is only important for bone health.
Many people don't know that vitamin D plays an important role in many bodily functions. Some of them include the immune system, the nervous system, heart and blood vessels and many more. 

Diseases connected to a Vitamin-D-deficiency

The following diseases are possibly linked to a vitamin D deficiency.

  • higher vulnerability for infections, chronic infections
  • Paradontitis, loss of teeth
  • Osteoporosis (Bone loss) and its precursors
  • Rachitis (Bone weakness in growing children)
  • Obesity
  • Skin conditions
  • Diabetes mellitus
  • Depressions, sleep disorders

A Vitamin-D-deficiency could be present, when you...

  • use sunscreen factor 8 or higher, when in the sun
  • have a (very) dark skin colour
  • live in Central or Northern Europe
  • get very little sunlight in wintertime
