Vitamin D is a key hormone for health, needed in the body for thousands of important processes and functions. A vitamin D deficiency has many serious implications for your health and athletic performance, and even a less than optimal supply of vitamin D can affect your performance and well-being. If you often feel exhausted and listless or are prone to colds, these could be the first signs of a vitamin D deficiency.
Especially serious for bodybuilders and athletes is the fact that a vitamin D deficiency lowers the body's own production of muscle-building hormones and can impair muscle strength and muscle coordination! If you combine this with the fact that, according to the latest research, almost 60% of all people in Germany suffer from a serious vitamin D deficiency, we have probably caught your attention. And this 60% represents only those people with a serious deficiency. Not included are those whose vitamin D levels are in the lower normal range, but not in the optimal range. Even these people can benefit noticeably from vitamin D supplementation, as many of the positive effects of vitamin D increase in direct proportion to the levels of vitamin D in the body. These numbers are not surprising, as especially in the winter, when the body produces virtually no vitamin D due to insufficient sunlight, our diet can only provide 10% to a maximum of 20% of our vitamin D needs. For the non-athletes among you, for whom muscle-building hormones and muscle strength are not so important, it should be mentioned that an adequate supply of vitamin D can reduce the risk of cancer by 15% and the risk of dying from a heart attack even by over 80%.
Some of the above sounds like pretty bad news. But now the good news: an adequate supply of vitamin D is dirt cheap and easy. Since vitamin D can be stored well by the body, one capsule GN Laboratories Vitamin D3 5,000 per week is enough to cover your vitamin D needs. And one can of GN Laboratories Vitamin D3 5,000 will last you 60 weeks - more than a year. If you're deficient in vitamin D - and there's at least a 60% chance you are - there's probably no more cost-effective way to significantly increase levels of muscle-building hormones in men, boost performance and well-being, and improve immune function - not to mention reduce the risk of dying from cancer or heart attack. What sets GN Laboratories Vitamin D3 5,000 apart from all other vitamin D products available? The biggest and most important difference of GN Laboratories Vitamin D3 5.000 is the depot dosage form, which allows you to meet your vitamin D needs with only one intake per week. Previously, you had to swallow a capsule or tablet every day to achieve this. Not only is this much more convenient and comfortable, but with the right approach, it can also improve absorption - especially for people on low-fat diets. Because vitamin D is a fat-soluble vitamin, optimal absorption by the body requires taking it after a higher-fat meal. With regular vitamin D products, this means you should eat a higher fat meal every day, while with GN Laboratories Vitamin D3 5,000, you only need one high fat meal per week. What exactly is vitamin D? Vitamin D is an essential vitamin that is needed in the body for many important processes. Strictly speaking, vitamin D is not a vitamin, but a steroid hormone. To complicate matters a bit more, vitamins D2 and D3 found in food and supplements are, strictly speaking, only prohormones that are converted to their active forms in the body. Another peculiarity of vitamin D is that it is the only vitamin that the body can produce on its own. With sufficient exposure of the skin to UVB radiation from the sun, the body can produce vitamin D from cholesterol. However, this only works to a sufficient extent if the UVB radiation from the sun is strong enough and the skin is exposed to this radiation long enough. This is not the case in the fall and winter months because the sun is too low and most of the skin is covered with clothing. Since food typically contains only very small amounts of vitamin D, vitamin D deficiency is very common in Germany - especially during the winter months. Vitamin D can be stored in the body in certain amounts in the liver and also in fat cells to serve as a reserve during periods of insufficient self-production and insufficient intake through food.
What functions does vitamin D perform in the body Vitamin D is involved in many processes, some of which are vital, and we can only give you an overview of the most important functions at this point.
The functions for which vitamin D is essential in the body include bone and tooth health and stability. Vitamin D is needed for the conversion of bone stem cells, which are precursor cells of bone cells, into bone cells. At the same time, vitamin D inhibits the formation of parathyroid hormone, which promotes bone resorption. Furthermore, vitamin D regulates calcium absorption in the intestine, as well as calcium and phosphate balance and metabolism in the body. Since vitamin D also promotes the storage of calcium in the bones as part of these processes, it contributes to a strengthening of the bones and a lower susceptibility to bone fractures to a decisive extent.
But vitamin D is not only important for a regulation of the calcium balance and the maintenance of stable bones. It is also responsible for maintaining muscle function. It not only promotes the development of muscle mass, but also improves muscle coordination and can thereby help reduce the risk of falls in older people.
Of particular interest to all men and especially bodybuilders is the fact that without sufficient amounts of vitamin D, the body's own natural production of muscle-building hormones decreases. Studies have shown that in healthy men, natural levels of muscle-building hormones were significantly increased by vitamin D supplementation. This does not necessarily mean that vitamin D is a hormone booster, but it certainly acts as a hormone booster in men who are vitamin D deficient or have sub-optimal vitamin D levels, as it raises the body's reduced production of muscle-building hormones back to normal. Vitamin D also boosts immune system function and is also important for brain development and function. As you can see, vitamin D has many important functions in the body. Unfortunately, conversely, this also means that all of these functions are significantly inhibited when vitamin D is deficient. We will discuss the exact consequences of a vitamin D deficiency in more detail below.
What health benefits can supplementation with GN Laboratories Vitamin D3 5.000 bring? Basically, most of the health benefits of supplementing with GN Laboratories Vitamin D3 5,000 are based on correcting an existing vitamin D deficiency and thereby ensuring an optimal supply of vitamin D to the body. But please do not stop reading at this point. The fact is that, according to studies, almost 60% of all people in Germany and Europe suffer from a serious vitamin D deficiency. This does not yet include people who have vitamin D levels that are in the normal range, but not in the optimal range. Without vitamin D supplementation, it is nearly impossible to maintain healthy vitamin D levels in the body, especially during the cold seasons.
If you suffer from fatigue, listlessness, and perhaps even depressive moods, it may very well be the result of a vitamin D deficiency. Numerous studies have shown that vitamin D supplementation can improve energy levels, concentration and performance, mood, and even sleep quality. Furthermore, in certain cases, vitamin D supplementation can alleviate depression, as it has been proven that the lower the levels of vitamin D in the body, the more severe the depressive mood associated with vitamin D deficiency.
Also, if you frequently suffer from infectious diseases such as colds, vitamin D supplementation could help you. An interesting study concluded that a daily dose of 800 IU of vitamin D reduced the risk of infection by 60% in people who were vitamin D deficient. At 2000 IU, the risk of infection was reduced by as much as 90%! Again, the lower the vitamin D levels in the body, the higher the risk of infection.
If you suffer from osteoporosis, vitamin D can help you in many cases, as this vitamin promotes the storage of calcium in the bones and thereby increases the stability of the bones. Less known is that vitamin D supplementation can improve strength and stability of muscles, since a vitamin D deficiency has exactly the opposite effect. Of particular interest to athletes and bodybuilders is the aforementioned fact that studies have shown that vitamin D supplementation can increase the body's production of muscle-building hormones in healthy men. More muscle-building hormones mean more strength, more muscles and increased athletic performance.
Few people know that vitamin D supplementation can significantly reduce the risk of cancer in at least 15 types of cancer, such as prostate, breast and colorectal cancer, because vitamin D can prevent the growth of cancer cells directly on site. Vitamin D can also inhibit tumor growth in existing cancer. A meta-analysis concluded that vitamin D supplementation can reduce cancer risk by 15%. With 230,000 cancer deaths in Germany in 2014, more than 34,000 lives could have been saved through vitamin D supplementation. Vitamin D supplementation can also help protect cardiovascular health. Danish scientists concluded that optimal levels of vitamin D in the body can reduce the mortality rate due to a heart attack by 81%. How does vitamin D deficiency occur and why does almost 60% of the German population suffer from it? As already mentioned, the body's own vitamin D production, for which sufficient UVB irradiation of the skin is necessary, is the most important vitamin D source for our body. However, during the months from October to March, solar radiation in our latitudes is too weak to sufficiently stimulate vitamin D production, which is exacerbated by the fact that during this time it is too cold to expose much skin to this low UVB radiation. Only during the months of April through September can the body optimally produce sufficient amounts of vitamin D on its own. Vitamin D produced in excess of requirements can be stored in the body to some extent, but there is also an upper limit on maximum daily production of vitamin D. Our modern lifestyle means that most people cannot spend enough time in the sun, even in the summer, to stimulate adequate vitamin D production. People who work in offices all day will often only get outside in the morning and from late afternoon. Unfortunately, at these times the sun is so low that the UVB radiation hitting the skin is too weak to stimulate optimal vitamin D production. To make matters worse, many people use sunscreen to a greater or lesser degree when they are exposed to the sun. This sunscreen often reduces the amount of UVB radiation hitting the skin to such an extent that vitamin D production is almost completely or even totally prevented. Even a sun protection factor of 10 reduces vitamin D production by 90%, and a sun protection factor of 15 or more virtually prevents vitamin D production altogether.
Theoretically, it would be possible to survive the winter with the vitamin D stored in the summer alone, but this requires that the maximum amount of vitamin D is produced on most days during the summer. For the above reasons, this is not the case for the vast majority of people and the longer the winter lasts, the sooner these stores are used up.
Furthermore, there are population groups that have an increased risk of vitamin D deficiency even with sufficient sun exposure. These include the elderly, as the body's production of vitamin D decreases sharply with age. This is supported by research showing that nearly 80% of seniors suffer from vitamin D deficiency. People with dark skin color also produce less vitamin D, as the dark pigments in the skin act as a natural sunscreen.
Vitamin D is also found in small amounts in certain foods. However, since these amounts are quite small, it is almost impossible to cover the vitamin D requirement through food. To do this, you would have to eat 1.3 kilos of mushrooms, 15 eggs, 2 kilos of hard cheese, 1 to 2 kilos of fish or over 7 kilos of liver every day. Our normal diet covers on average just 10 to 20% of the daily requirement of vitamin D. Against this background, it is not surprising that a study conducted by the Robert Koch Institute came to the conclusion that almost 60% of all Germans suffer from a serious vitamin D deficiency. The results of this study are in line with the results of other studies in Europe and America.
What are the consequences of vitamin D deficiency?
Due to the many important bodily processes in which vitamin D is involved, the consequences of vitamin D deficiency are very diverse. The first symptoms often include fatigue, listlessness, reduced performance and increased susceptibility to infectious diseases such as colds and flu. It is not for nothing that the flu often rages the hardest in February and March. At this time, the body's vitamin D stores are depleted in most people, and this weakens the immune system.
Depressive moods can also be signs of a vitamin D deficiency, whereby these symptoms become more pronounced the lower the vitamin D levels in the body are. A vitamin D deficiency, along with other factors, is held responsible for the so-called winter depression. For athletes and bodybuilders, the reduced performance in the case of a vitamin D deficiency is particularly critical, which is further aggravated by the fact that an insufficient vitamin D supply lowers the body's own production of muscle-building hormones and thus also the levels of free, active muscle-building hormones in the body. Not to mention that vitamin D deficiency inhibits muscle growth and impairs muscle coordination.
However, vitamin D deficiency can also cause much more serious health problems. These include rickets in children and the corresponding disease in adults called osteomalacia. The main feature of these diseases is soft, deformable bones, which often results in bow legs and, in children, can also cause deformation of the spine.
A more widespread and well-known health problem, caused in part by vitamin D deficiency, is osteoporosis. In this disease, bone density decreases due to demineralization of the bones, dramatically increasing the risk of bone fractures even at low levels of stress. Of course, since adequate vitamin D intake reduces the risk of cancer and greatly reduces the death rate from heart attacks, the reverse is also true: vitamin D deficiency significantly increases the risk of cancer and the risk of dying from a heart attack.
But it does not have to come so far. Just one capsule GN Laboratories Vitamin D3 5.000 weekly is enough to completely cover your body's need for vitamin D and protect you from all those unwanted and dangerous deficiency symptoms.
Who is particularly at risk of vitamin D deficiency? In principle, all people living in the northern and middle latitudes of the earth, where the sun's rays are not strong enough for many months in a row to enable sufficient endogenous vitamin D production, are at risk. However, there are some people who are particularly at risk of vitamin D deficiency: "couch potatoes," office workers, and bedridden people: All of these people spend most of their time indoors and therefore often do not get enough sunlight, even in the summer months, to ensure adequate vitamin D production.
Elderly: As people age, the body's ability to produce vitamin D continues to decline and can be as much as 75% lower in a 70-year-old than in a 20-year-old. People who are exposed to the sun only with sunscreen: Even though sunscreen is recommended from a skin cancer prevention standpoint, it simultaneously inhibits the body's vitamin D production. A sun protection factor of 10 already reduces vitamin D production by 90%, and from sun protection factor 15 the body's own vitamin D production comes to a complete standstill due to sun exposure.
People with dark skin: The dark skin pigment melanin acts like a natural sunscreen, so that less vitamin D is produced in the sun. For this reason, dark-skinned people in northern and central latitudes should supplement with vitamin D even in summer to prevent deficiency. Pregnant women and menopausal women: During pregnancy, vitamin D requirements can increase significantly. Vitamin D deficiency is also common during menopause due to hormonal changes.
Vegetarians: Since vitamin D is found in the highest concentrations in meat and fish, vegetarians consume on average 50% less vitamin D than "carnivores" through their diet. Overweight people: Even though vitamin D in the body is primarily stored in fatty tissue, in overweight people it is often no longer released into the blood by fatty tissue. At just 10% overweight, vitamin D levels can drop by over 4%, and at higher weights, vitamin D levels drop even more significantly. People treated with corticosteroids such as cortisone: Corticosteroids, which are often used in the treatment of sports injuries, deplete the body's vitamin D3 stores, which can result in vitamin D deficiency.
FAQ: Are people suffering from kidney stones allowed to use GN Laboratories Vitamin D3 5,000? If you suffer from kidney stones, you should definitely discuss vitamin D supplementation in advance with your treating physician. He will calculate on the basis of your vitamin D blood levels, how much vitamin D you can take with supplements. Should GN Laboratories Vitamin D3 5,000 be taken with food? Since vitamin D3 is a fat-soluble vitamin, it should be taken after a meal that contains some fat, otherwise the absorption of the ingested vitamin D may be impaired. Is an overdose of vitamin D possible? Vitamin D overdose is possible and undesirable due to its possible negative effects on health. However, an overdose only occurs when more than ten times the recommended amount of vitamin D is taken daily over several months. For these reasons, please always adhere to the recommended intake of GN Laboratories Vitamin D3 5,000.
