Should we always take vitamin D supplements in the winter?

Supply of vitamin D deficiency in Germany

Studies have shown that the vitamin D supply in Germany is flawed. Not only adults, but many children and young people have degrading values. If vitamin D is in fact a supplement supplement, after a medical examination – it is advised in many cases. But some people take such preparations unexplored from this and so on. This does not make sense, experts warn.

No protection from chronic diseases

Some people take supplements because they think they are doing something good for their health and preventing illness. Stiftung Warentest notes his website that this does not really make sense.

Because scientists have evaluated hundreds of studies in recent years to the question whether vitamin D protects from other chronic diseases and did not find any convincing effect.

For example, in an earlier statement of the German Endocrinology Society, it was stated that vitamin D could not reduce the risk of cancer, cardiovascular disease, high blood pressure and type 2 diabetes mellitus.

Sunlight in the cold months is not enough

Vitamin D is also referred to as "vitamin" because the human body makes about 80 to 90 percent under the influence of sunlight. The high energy UVB rays that are also under the skin are determined.

However, not everyone does the same vitamin D – it depends on age, skin thickness and skin type.

According to Stiftung Warentest, the general rule is that the sun in Germany from October to March is not enough for people to produce enough vitamin D. But not the skin that does not produce vitamin D the fall and the winter.

"The body also makes some vitamin D, if you go a bit in the winter with a face and gloves for some time, about 20 to 30 minutes," said Cymdeithas spokesperson the German Endocrinology, Professor Helmut Schatz.

But especially in the warm months, enough sunlight is needed. Due to the sun during spring and summer, the storage of vitamin D can be easily filled, as the body stores vitamin D with fat confidence in the fat tissue and muscle and # 39 ; r afu.

This stock is usually adequate to come without shortcomings over the dark season.

The diet can only be a small part of the need

As Stiftung Warentest writes, only a small part of the vitamin D requirement can be met with food, for example, ten to 20 percent. Accordingly, only a few foods contain a significant amount of vitamin D.

Most are in fatty fish such as salmon and pepper. To a much lesser extent, liver, yellow eggs and some mushrooms such as chanterelles and mushrooms provide vitamin D.

Those with vitamin D levels are too low due to lack of sunlight during the winter months, according to health specialists, a destination for dietary supplements.

However, pils with vitamin D are not recommended to everyone, as experts warn Apothekerkammer Niedersachsen.

Basically, too much can not be taken. Due to the German medical profession drug commission (AkdÄ), it can also lead to an oversight with vitamin D. supplements.

Another problem is that many of these products are not recommended, as a study commissioned by "Öko-Test" has shown.

Nutritional supplement for risk groups

"Healthy, Delicious additives are scarce healthy people," writes Stiftung Warentest. "For some risk groups, however, they can be useful."

This includes people over 65, but not limited to, so many people of this age reduce their ability to produce vitamin D. In part, then it produces only half as much of vitamin D as in previous years of life.

Even young people, who rarely enter fresh air due to illness, can go to vitamin D supplements after consulting with a doctor.

Under these conditions, Warentest Stiftung distributes such medicines as suitable for the prevention and treatment of osteoporosis.

Vitamin D pollenes can also be useful for some other illnesses: For example, small intestinal diseases can disrupt the vitamin D absorption of the bowel.

Chronic liver disease, renal inadequacy, parathyroid failure or some medications such as anti-epileptic can also interfere with the production of vitamin D.

Never take vitamin D supplements on suspicion

In addition, the Institute recommends child health in accordance with pediatrician scientific institutions:

All babies in Germany from the first week of life until the second experience in early summer, therefore depending on the date of birth for a period of one to one and a half and a half, as well as breast milk or tablet of infant food or day to day fall 400 to 500 units of vitamin D 3 may be prescribed by a doctor,

Vitamin D supply should be best combined with fluoride profhylaxis against tooth decay. Pre-age babies weighing less than 1,500 grams should receive a daily daily dose of 800 to 1,000 units of vitamin D during the first few months of life.

Basically: "Vitamin D supplements should not be taken on suspicion. They are only recommended if there is not enough care to be tested by a doctor, but Antje Gahl of the German Nutrition Society ( DGE).

Then, the doctor specifies the current vitamin D status, if necessary. However, just for this blood test if there is a reasonable doubt of a deficiency, such as osteoporosis, people with legal insurance can be repaid.

The doctor and the patient must decide on a case if the test makes sense. Most patients pay the cost of the investigation of around 20 to 30 euros themselves. Also pays for vitamin D supplements in exceptional cases only. (Ad)
