Vitamin D in winter: why dietary supplements can be useful

Vitamin D is also known as the “sunshine vitamin” because it is produced by the body using UV rays. How many minutes or hours a day you need to spend in the sun to get enough vitamin D depends on many factors. Among other things, the time of year and the day. In winter the sun in this country is not as intense as in summer. So you have to spend more time outside to get enough vitamin D. The Federal Office of Public Health provides guidance for light, light-medium and dark skin types. Here is the overview:

Light skin types:

January and December >5 hours from 2 to 7 hours too little sun to be sufficient vitamin D produce
February and November from 3 to 5 hours From 45 minutes to 2.5 hours too little sun to be sufficient vitamin D produce

February and November from 4 to 8 hours From 1.5 hours to 5 hours too little sun to be sufficient vitamin D produce

As can be seen from the tables, in the months of January and December it is difficult to take in a sufficient amount of vitamin D on a daily basis, even for fair skin types. According to the RKI, in winter the body can draw on its reserves of vitamin D in adipose and muscle tissue. However, it becomes problematic if these storage facilities are not sufficiently filled even in summer. The reasons may be different, as the climate also plays an important role in the production of vitamin D in summer. Illnesses such as gastrointestinal inflammation or certain medications can also make it difficult to absorb vitamin D.

If you want to know more about your vitamin D stores, you can have a blood test done by your doctor. However, the health insurance company will only cover the costs if there is suspicion of a defect. A good vitamin D level is between 30 and 40 nanograms per milliliter. If you have less, you should consider supplementing with vitamin D tablets in the winter. The sunshine vitamin is hardly contained in foods. Oily fish and mushrooms, among other things, can contribute to the winter supply.

The best-known vitamin is vitamin C. It protects cells from oxidative stress and supports the immune and nervous system.

The Cochrane research network evaluated 29 studies on the topic and came to the conclusion that long-term intake of vitamin C can reduce the duration of colds by 8% in adults and 14% in children. But the dosage is important: according to the DGE the daily requirement for adults amounts to 95 (women) and 110 (men) milligrams per day. This value can easily be achieved through foods containing vitamin C, such as peppers or broccoli. Although the body excretes excess vitamin C through urine, vitamin C poisoning can occur at very high doses.

Especially in the cold season it is advisable to make sure you sufficiently cover the daily requirement of vitamins A and E through your diet. A food that provides the body with a particularly high quantity of vitamin A are, for example, carrots.
