Our 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.

Please note: Nutrient levels always indicate your current nutrient intake. The tested laboratory values and hints should be a guide. The results serve exclusively to prevent and optimize your nutrition. They should not replace treatment by a doctor. The results of the kiweno vitamin D test therefore do not represent symptoms or diagnoses.

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.

Vitamin D is one of the fat-soluble vitamins and is largely produced by the body itself – for this process sunlight is needed (UVB rays). If you regularly stay in the sun, the vitamin D supply is normally guaranteed. However, since most people spend most of their time indoors and only spend limited time in the sun, a vitamin D deficiency is often pre-programmed. In Northern and Central Europe a large part of the population is affected.

Function
The so-called “sun vitamin” supports more than 30 body functions. For example, the vitamin raises your mood, supports the function of your pancreas (diabetes mellitus), reduces inflammation parameters, reduces the risk of cardiovascular disease, strengthens the immune system as well as lung function, strengthens your muscles and strengthens bone structure.

Symptoms of deficiency
Chronic fatigue, bone softening, immunodeficiency, inflammation and a depressed mood can indicate a vitamin D deficiency. Especially in the sunless autumn and winter months we often feel this in the form of an “autumn low” or “winter blues” as well as increased susceptibility to flu-like infections.

The test system of the kiweno vitamin d rapid test consists of an immunological rapid test, which detects vitamin D (25(OH)-vitamin D) using specific antibodies, and a smartphone app, which quantitatively evaluates the result of the rapid test based on the colour intensity of the control and test band. The result is displayed and stored on the smartphone in use. The system requirements and supported devices can be found at kiweno.com/vitd-schnelltest

Vitamin D belongs to the group of calciferols, which is a collective term for various substances of this type. Calciferols can be taken in active or inactive form through food. However, your body is also capable of forming a precursor itself: this happens in the liver and in the intestinal mucosa. Your skin needs sunlight to activate the precursors. Activation then produces vitamin D, which is important and effective for you. It is therefore important that you regularly expose your skin to the sun in order to activate the vitamin D on your skin under the influence of UV light.

The functions of the fat-soluble vitamin in the human body are numerous. Vitamin D, for example, strengthens the cardiovascular system, has an effect on the function of your thyroid gland and thus also on your hormone balance and the immune system. Vitamin D also plays an important role in regulating your calcium level and thus supports bone mineralization. A well covered vitamin D level is therefore an important protection against osteoporosis. The promotion of muscle development and function is also related to vitamin D. This is particularly important for older people, as they often have a low vitamin D status. In addition, it supports glucose utilization, which is why vitamin D is particularly important for diabetics. Vitamin D is also known for its positive effects on the state of mind. Recent studies indicate that low vitamin D levels are associated with mood swings and even depression. It is not yet clear whether the lowered concentration contributes to the disease or whether the clinical picture lowers the vitamin D level.
