Vitamin D especially important in the cold season

Vitamin D in the cold season: the Bremen Chamber of Pharmacists recommends an examination by a doctor
Many people are familiar with this: they now feel tired, tired, forgetful and tend to feel depressed in winter. However, it is not the Bremen weather that is to blame, but in many cases an undersupply of vitamin D. "Around 80 percent of all people living in Germany have a poor vitamin D value in winter," says Richard Klämbt, President of the Bremen Chamber of Pharmacists. One could do something about a deficiency.

In the cold season we often feel rather sickly, the darkness and cold do the rest, so that many people easily get into a depressed mood. However, very few think about having their vitamin D value examined by a family doctor. "Permanent fatigue, susceptibility to infections and a bad mood can be too low," explains Klämbt. A good normal value is 35-60 ng / ml or 80-150 nmol / l. Everything below indicates an undersupply, with a value below 20 ng / ml or below 50 nmol / l one speaks of a vitamin D deficiency.

Ensure adequate vitamin D supply
Vitamin D belongs to the group of fat-soluble vitamins and is synthesized in the human body using UVB radiation. According to the Robert Koch Institute, every person with whom the body's production of vitamin D works perfectly is adequately supplied with vitamin D in the sunny months if they regularly spend time outdoors. The situation is different in the darker months of October to March: here the sun is too low and shines too rarely for the body to be able to generate enough vitamin D with its radiation.

Theoretically, the necessary amount of vitamin D can also be taken in through food, but it only occurs to a very small extent in food. Most vitamin D is found in oily fish such as mackerel, salmon or herring. Egg yolk, liver and some edible mushrooms also contain the vitamin. However, to get a helpful amount of vitamin D from your diet, you would need to eat more than a kilo of high-fat fish three to five times a week. It is therefore more advantageous for the figure to take a high-quality vitamin D preparation from the pharmacy in an individual dosage.

Professional advice before taking it is important
To determine the current vitamin D level and the necessary dose of a corresponding preparation, a blood test should be carried out at the doctor. “We recommend advice from a doctor or pharmacist before you take vitamin supplements. Overdosing or a disadvantageous combination of the preparations can possibly have negative health effects, ”warns Richard Klämbt. Pregnant women should follow the recommendations of their gynecologist.
