Vitamin D: Deficiency symptoms in winter lead to these diseases


Have a doctor check the vitamin D level
A third of the German population is poorly supplied with vitamin D. This was determined by the nationwide "Study on Adult Health in Germany" (DEGS) in summer 2017. Especially in winter, many people have a vitamin D level that is too low. Between October and April, the sun's UV-B radiation is no longer sufficient for us to form the vital vitamin D.

"Vitamin D is involved in the development or prevention of almost all chronic diseases," says Professor Dr. med. Jörg Spitz, the President of the Society for Biological Cancer Defense e. V. (GfBK). Vitamin D has an anti-inflammatory and immunostabilizing effect and can protect cancer patients from relapses and metastases. The company therefore recommends that the vitamin D level in the blood be checked during the cold season and that the blood be 30 to 50 ng / ml.

Experts speak of the "vitamin D winter". Between October and April, the sun's UV-B radiation is no longer sufficient for us to form the vital vitamin D. In winter, the blood level drops to a level that is hazardous to health. Around a third of the German population is poorly supplied with vitamin D, the nationwide "Study on Adult Health in Germany" (DEGS) found in summer 2017. They have a serum concentration of <30 nmol / l 25-hydroxyvitamin-D (= less than 12 ng / l). Just under 40 percent are adequately supplied, according to the 13th DGE
report of the German Society for Nutrition e. further. Experts consider the ideal value to be 30 ng to 50 ng vitamin D per ml blood.

Proven means: measure vitamin D levels
Most people don't notice the low vitamin D level. Symptoms such as tiredness, the "winter depression", muscle weakness or a poor immune system are often not attributed to the missing sun hormone. But too little vitamin D is dangerous for healthy people and for cancer patients. "Vitamin D is involved in the development or prevention of almost all chronic diseases," says Professor Dr. (GfBK).

The company therefore recommends that the vitamin D level in the blood be checked during the cold season and that the blood be 30 to 50 ng / ml. "Especially cancer patients should at least in winter additionally vitamin D preparations with 2000 IU. (International unit) daily, ”says Dr. György Irmey, Medical Director of the GfBK. Food, such as high-fat fish or dairy products, can cover a maximum of 20 percent of the “sun hormone” requirement. A Christmas holiday in the sun is also not enough for the rest of winter, according to studies.

Shield against cancer and other diseases
The positive effects of vitamin D have been proven by numerous studies. It has an anti-inflammatory and immunostabilizing effect. A good vitamin D supply can protect against relapse and metastases, such as: B. found the review of the German Cancer Research Center (Maalmi H / Eur J Cancer 2014). So far, this has been proven primarily for breast and colon cancer patients. "People with a high level of vitamin D in the blood are up to 40 percent less likely to develop colon cancer," Professor Spitz quotes a large study involving more than half a million people from ten Western European countries (Jenab et al./British Medical Journal 2010 ). But vitamin D also has a preventive effect against other diseases such as rheumatism, bone diseases such as osteoporosis and heart attacks.
