There is little other vitamin with such varied and important functions in the body such as vitamin D. The most well-known in this context is that vitamin D can protect from infections, it is also important to have enough from the sun, because that is to produce the body's own vitamin D can crank. Therefore, vitamin D is often referred to as "vitamin".
What many people do not know: Vitamin D is only a generic name for a whole group of essential substances, from vitamin D1 to D5. However, the most important type of health related is vitamin D3, the scientific name of colecalciferol. Through several stages of synthesis, it is transformed by the body into the active biological form. Therefore, talking about vitamin D health, there is usually D3.
Vitamin D – the only vitamin that our body can produce in itself
Although we need to raise other vitamins, such as vitamins B, C and E, the body can produce vitamin D alone. The prerequisite for this is UV radiation. When sunlight strikes the upper layer of skin, vitamin D predecessors will turn the vitamin D3 which is biologically functionally supported by UVB radiation and lipoproteins (which contains cholesterol) on the skin.
In this way, 80 to 90 per cent of vitamin D. requirement are completed. This is 20 micrograms per day. Too much vitamin D deposits the memory into the memory, which has been located in the liver and adipose tissue. It can usually return back to the reserves in the low season.
It has ten to 20 percent of vitamin D requirements, the organism receives from food. Rich in this vital substance is fat fish such as fish and salmon, as well as liver, mushrooms and yellow eggs. However, much of it would have to be eaten, so that significant amounts of vitamin D come together – which is practically impossible.
Supervitamin D could be important for each cell
In fact, this vital substance is a hormone or pro-hormone precursor that can stimulate and control the accumulation of other hormones. Accordingly, its wide range is flexible to its functions. There is still more discovery. Because vitamin D, or D3 not only plays a part in the hormone and immune system balance. It is now known that almost all body cells have also vitamin D. receptors. Therefore, the spectrum of Supervilaminas could be much more than previously identified.
Vitamin D – not only important for bones and immune system
The following tasks of Vitamin D are already known and have been tested to date:
immune system: Without vitamin D, some immune cells can not work at all. These are, for example, T cells that belong to the group of lymphocytes. In the process, vitamin D plays an important dual role: on the one hand it promotes the production of some immune cells, on the other hand, the immune response modulates are excessive to normal levels. This makes vitamin D as valuable in automatic illnesses such as rheumatoid arthritis and even multiple sclerosis. Several studies indicate that vitamin D deficiency can play a part in these diseases.
form a boneVitamin D is important to be mineral enough to the bone. It regulates the function of bone build cells, mainly osteoblasts. So, vitamin is just as unpleasant to healthy bones such as calcium. Rickets is the most well-known example of what vitamin D deficiency can do in the bone in the worst case. This deficiency disease led to serious malformations in children at the beginning of the last century (softened bone, sawmill and more).
muscles: Vitamin D also helps to build muscles and protect some of the age-related muscle cutting, which an investigation indicates.
Brain and nerve: Studies in recent years have shown that vitamin D could play an incredible role in preventing various brain and nerve diseases, such as dementia such as Alzheimer's disease, Parkinson's disease, as well as a stroke. In addition, vitamin D can reduce the risk of reducing the elderly significantly. Old age falls as a high risk factor for long-term care. Because it often causes a broken femoral neck, which can lead to bed rest and incapacity.
depressionEspecially in the winter depression known as a lack of light, vitamin D can positively influence the mood. In addition, recent studies show that there is a link between severe depression and vitamin D deficiency.
cancerThe fact is that, in poor areas of the sun, the cancer rate is higher than in regions near the equator. This is because mild deficiency causes vitamin D deficiency, among other things. Studies have explored this in more detail and found evidence that vitamin D could reduce the rate of cancer cell division. It's probably related to colon cancer, lung cancer and breast cancer. However, further studies are needed.
diabetes: There is evidence that vitamin D can have a positive effect on blood sugar. Diabetes metabolism was shown to benefit from vitamin D.
cardiovascular diseases: Vitamin D could cause plaques in the blood vessels to not form and deposit so fast. This would protect the essential substance of arteriosclerosis, the most important risk factor for heart attack and stroke.
Uncomplicated pregnancy: Vitamin D is not only important during pregnancy, so that the child develops well, but also that there is no significant diabetes developing. These relatives are well-studied scientifically well.
Sexual power for man and wife: The regulation of hormones depends on vitamin D in many ways, which, as mentioned above, is actually a hormone precursor. This property also comes in when forming sex hormones. Therefore, a good supply of vitamin D is associated with the formation of testosterone sufficiently in men. Vitamin D can improve fertility in men and women.
Vitamin D makes sense of obesity
Scientists are constantly finding the further effects of this supervision. This is currently the relationship between vitamin D and obesity. In a study with obese children, it showed that vitamin D adds to the body mass index (BMI) is reducing, body fat reductions and blood lipid levels are improving.
Lack of vitamin D in the rich society
On the other hand, the wide and increasing range of vitamin D actions clearly indicate which massive health problems can mean the lack of this vital substance. Because even if most people today are well-fostered and they are more outdoors than earlier, when children often had rickeys: vitamin D3 deficiency is more common than presumed. More than half of the Germans have been undermined and this vitamin D deficiency is even increasing.
The cases over this:
- Many people use sunscreen. That makes sense about preventing skin cancer. However, a sunscreen protects the skin so effectively that the UV rays do not harm but can not work. Forming vitamin D is thus slowed down.
- Great dust and smog reduces the amount of sunscreen that squeezes the skin.
- Rarely some groups come outdoors. In the past, these were mainly in the elderly and chronic illness. Today, this risk group is also related to infants because they are scarce in the fresh air.
- For example, there is even a danger to the people who are dealing mainly with cultural reasons.
Prevention and vitamin D deficiency balance
However, vitamin D deficiency signs are not always clear, ranging from exposure to infection to boreal bone pain. Those who want to be sure can get their vitamin D levels tested by the doctor (which costs about € 30). Often, the doctor will advise on the addition of vitamin D, and not just in summer.
We recommend daily doses starting from 1000 units (IE). By the way, there is not too much because the liver and kidneys first have to convert vitamin D and absorb it in its active form. And they only do this when it is really necessary, before the essential substance is still inactive.
Conclusion: Vitamin D plays an important role in our health. It is mainly synthesized by UV radiation in the skin. However, many factors mean that this internal production can only be slowed down from the vitally important substance, such as the foul air in our cities. The lack of vitamin D is associated with various diseases of the disease – from being exposed to infection and even even to cancer, but science needs to be further investigated. With vitamin D supplements, shortcomings can be specifically damaged.
