"Let the sun into your heart ..."

This was the title of the song by the group Wind at the Eurovision Song Contest 1987. And somehow, this title also fits the theme very well Vitamin D, the sunshine vitamin!

But is the Sun alone sufficient?

Basically, everyone probably knows that Vitamin D very important ist.

But what for? Is it just a hormone? Is it only a sunshine vitamin?

It is lebenswichtig für die Knochengesundheit, this is how most people estimate the primary effect of vitamin D. However, it also plays a very important role in relation to the Muscle Health, has a significant effect on Nerve connections in and to the brain and takes on important functions in connection with our Immune system in!

Let's once Vitamin D in detail!

What exactly is vitamin D?

Vitamin D is, like all vitamins, basically first and foremost a lebensnotwendiger nutrient. Our body produces aktives Vitamin D nach Sonneneinstrahlung, and we also get some vitamin D through the Food up.

In addition, vitamin D is also a Hormone. Hormones control the Function of Cells and Organs.

Nevertheless, vitamin D is not referred to as a hormone because it far more diverse tasks perceived in the body.

Both can, for example, help to remedy a vitamin D deficiency, Vitamin D3 is to be preferred, as it relates to the Better classify bioactivity is and therefore more effective in the event of a possible deficiency is.

What does vitamin D do in the body?

Vitamin D verbessert die Aufnahme anderer Nährstoffe through our body, especially we know this in the case of Calcium and Phosphorus, both of which are for the Bone Health are important.

Some studies show a possible connection between vitamin D and the Protection against cancer, heart diseases, bacterial and viral infections and more.

Vitamin D also regulates many other Zellfunktionen im Körper. His entzündungshemmenden, antioxidativen und neuroprotektiven Eigenschaften support not only muscle function or the activity of brain cells, all of which are undoubtedly very important, but also the Immune system!

Wie kann man einem Mangel entgegenwirken?

When the skin the ultraviolet rays of the sun exposed, the body produces vitamin D. That is why the principle still applies today to täglich ausreichend Zeit zu nehmen, um an die Sonne zu gehen. But that is not always feasible, and especially our usually fixed daily routine sometimes does not allow it.

Not too rarely, one tries to postpone it to the weekend, takes a sunbath, and, because of skin cancer, also pays attention to the use of Sunscreens. And exactly these, even if sensible, in turn prevent the synthesis of vitamin D.

But also our Lifestyle partially prevents vitamin D synthesis!

If we look at our way of life today, it is also quite easy to understand.

We spend a large part of our lives, our daily available time, in buildings, in the office, in the apartment, on the bus or train, in the car or especially in the cold season in warm places. So often behind window panes, which seemingly let sunlight through. But is the light that is available to us through window panes sufficient to produce enough vitamin D? No, unfortunately not!

That basically has two reasons. On the one hand, it is due to the low sun position in winter and the shortened sunlight hours, but also on the fact that Glass that filters the UV rays important for this purpose and thus restricts or prevents the formation of vitamin D.

Hand on heart, in winter we all like to retreat behind the protection of the insulating panes, like in a heated conservatory, right?

Vitamin D Deficiency – Myth or Problem?

To get to the bottom of this question, let's first turn it around and deal with the possible problems or symptoms eines typischen Vitamin-D-Mangels.

For most people, a Vitamin D deficiency symptom-free ab, which does not mean, however, that it cannot be present. In addition, it is often not quite so easy to classify the symptoms, as they typically can appear as follows:

Ermüdung, poor sleep quality, musculoskeletal pain or basically pain, psychological problems such as depression or sadness, hair loss, muscle weakness, loss of appetite, a sickly disposition, or pale skin.

It is quickly apparent that a Vitamin D deficiency not quite so easy to diagnose or can be determined.

But if such symptoms occur, then it definitely makes sense to weiter mit der Thematik zu befassen and to undergo further examination if necessary.

Is the defect now considered as Myth or as a problem to consider?

The previously described symptoms of a deficiency are indeed increasingly observed. And also within the scope of the studies, based on blood analyses, this trend can largely be traced.

According to recent studies, in the USA around a quarter of the population has a vitamin D deficiencytext . [1]

It is even sometimes assumed that this number could be somewhat higher.

For this reason, there is also a current international review article that we want to take a closer look at.
