Vitamin D3: sunshine vitamin
Vitamin D has been given the nickname "sunshine vitamin" because it can be produced by the body itself. For this it needs the UV-B radiation of the sun. An interesting synthesis takes place in the upper layers of the skin when there is sufficient exposure to the sun: UV-B radiation converts a form of cholesterol into vitamin D3 (cholecalciferol). In the liver, D3 is then converted into calcidiol, the storage form of vitamin D. It is available in the blood for about 15 days and, if required, calcitriol, the active form of vitamin D, is produced from it in the kidneys.
Function of vitamin D
Vitamin D has the task of calcium absorption from the intestine, so that the body always has a normal calcium level in the blood. This calcium is required for bone and tooth mineralization and for muscle function.
On the other hand, vitamin D plays an important role in the immune system, as it activates the killer cells of the immune system.
Vitamin D deficiency
Although the body is able to produce vitamin D itself, vitamin D deficiency is widespread because nowadays the skin is less and less exposed to direct sunlight. Think, for example, of our elderly fellow citizens, whose everyday life hardly takes place outside.
The amount of vitamin D production also depends on the climate, the amount of direct sunlight, the number of pigments in the skin, the season, sunscreen use and age.
With the food supplement from Fairvital you can prevent a vitamin D deficiency or maintain a normal vitamin D level in the blood. Each capsule contains 500 IU (12.5 µg) cholecalciferol.
Foods with vitamin D
Vitamin D is unfortunately only found in limited amounts in food. The best sources are, for example, in high-fat fish such as herring or salmon, egg, cheese, and butter, as well as mushrooms, avocado, and vitamin D-enriched margarine.
Vitamin D is found in two different forms in animal and plant-based foods: animal sources provide vitamin D3, while plant sources provide vitamin D2 is included. In principle, the body can convert vitamin D2 into vitamin D3 very well, but the effectiveness of vitamin D3 is better because the body can use it directly.

Nicht nur fürs Immunsystem interessant
Vitamin D hatte ich zunächst hauptsächlich wegen seines Beitrags zu einer normalen Funktion des Immunsystems im Blick. Dass es zusätzlich zur Erhaltung einer normalen Muskelfunktion beiträgt, fand ich als sportlich aktiver Mensch genauso interessant. Dadurch hat D3 für mich gleich zwei nachvollziehbare Funktionen.

Mein Balkon ist leider kein Ganzjahres-Arbeitsplatz
Im Sommer arbeite ich gelegentlich draußen und bekomme dabei automatisch mehr Tageslicht. Sobald das Wetter schlechter wird, verschwinden Laptop und ich wieder nach drinnen. Genau dieser starke saisonale Unterschied ist für mich ein guter Anlass, Vitamin D3 nicht erst mitten im Winter wiederzuentdecken.

Zähne hatte ich bei Vitamin D wirklich nicht erwartet
Muskeln, Knochen und Immunsystem kannte ich zumindest vom Hörensagen. Neu war für mich, dass Vitamin D auch zur Erhaltung normaler Zähne und zu einem normalen Calciumspiegel im Blut beiträgt. Solche weniger bekannten Funktionen machen das Vitamin für mich interessanter, als der Begriff „Sonnenvitamin“ vermuten lässt.

Meine Laufrunde beginnt meistens erst, wenn die Sonne weg ist
Ich bewege mich zwar viel, aber unter der Woche eben häufig erst am Abend. Dadurch habe ich irgendwann gemerkt, dass „sportlich sein“ nicht automatisch bedeutet, viel Tageslicht abzubekommen. Vitamin D3 ist deshalb für mich gerade in den dunkleren Monaten ein Thema.

Viele Menschen haben einen schleichenden Vitamin D Mangel; grundsätzlich kann es ja durch das Sonnenlicht selbst gebildet werden, doch ist mittlerweile bekannt, dass das selbst in den Sommermonaten nur unzureichend funktioniert. Toll, das Präparat von fairvital!

Highly dosed vitamin K2, natural menaquinone MK7, pure substance In the past, vitamin K2 was primarily linked to the blood coagulation, but during the last years it came into the focus of research and it turned out that it has many different functions in the body. There are numerous recent studies with surprising contents. Bone strength Bones are constantly broken down and regenerated and vitamin K2 plays an important role in this. It is needed to bind calcium to osteocalcin which is a part of the non-collagenous matrix of the bones. Osteocalcin is also an active part in the tooth formation. Laboratory diagnostically, osteocalcin is a significant parameter for the evaluation of the bone regeneration activity (bone formation parameter). Heart and blood vessels When too much calcium is taken in through food, it often deposits in the blood vessels – just like lime from the water deposits in the coffee machine. If sufficient vitamin K2 is available, it will ensure the calcium is transported to where it belongs: the bones and the teeth. A new study shows that vitamin K2 is not only able to counteract calcium deposits, but to reverse them as well. First results were already measurable after a few weeks. Further researches are necessary, but the first results are more than encouraging. Cell health There are indications that vitamin K2 is able to repair damaged DNA in the mitochondria. Pregnancy During the pregnancy and especially just before the birth, the body of the mother will go through natural changes. The organism strives for a minimal blood loss during the birth and activates all elements which are involved in the blood coagulation, but the activation of the coagulation factors can result in an increased risk for the formation of a blood clot (thrombus) in a blood vessel. Vitamin K2 helps to regulate the delicate balance. natural menaquinone MK-7 (>94%) can protect the blood vessels against calcium deposits promotes strong bones and healthy teeth highly dosed tablets without bulking agents and additives pure substance Combination tip: This vitamin K2 product is especially suitable for the combination with highly dosed vitamin D3

In our body is approximately one kilogram of calcium. 99% is bound in the skeleton The remaining 1% is divided as follows: 0.5% is found as calcium ions in the blood serum, the other 0.5% is bound to proteins. Calcium is the main component of our bones with 65% and is responsible for both the construction of the bones and their structure. Calcium is therefore of great importance for the stability of our bone structure. Calcium for strong bones Bone structure is built up and broken down throughout life, which is why adequate calcium intake must always be ensured, especially during growth. Up to the age of 35 years, the build-up processes predominate and the bone mass increases constantly. After that, the degradation processes predominate and the bone mass normally decreases by about 1.5% per year. Even during this time, an adequate calcium intake of at least 1000mg daily (source: Deutsche Gesellschaft für Ernährung e.V.) is essential. Calcium for the heart In addition to building bones, teeth and the palate, calcium prevents the storage of lead and helps in the regulation of heart rhythm. In this context, it also promotes a healthy cardiovascular system. In addition, it has importance for the transport of nerve impulses and the cholesterol level. The mineral ensures the permeability of cell membranes and stabilizes them by combining with phospholipids. Calcium is also a component of fat-splitting enzymes and the structure of DNA and RNA. The insulin secretion from pancreatic B cells is regulated by calcium. In addition, calcium plays an important role in the activation of the blood clotting system, where it forms complexes with phospholipids and clotting factors. In addition, calcium can support a balanced acid-base balance and counteract the drop in pH. This prevents demineralization of the teeth and promotes remineralization. Calcium to support a normal body weight In the fight against excess pounds, calcium seems to be helpful. Various scientific studies have found evidence that calcium plays a role in regulating body weight. Increased consumption of calcium-containing foods has been associated with lower body weight, weight loss, and lower body fat. The reason for this is that calcium in the intestine reduces fat absorption by binding dietary fat and excreting it undigested. Other studies have concluded that higher calcium intake as part of a calorie-restricted diet leads to greater weight loss than low calcium intake.In addition, it has been scientifically proven that the development of obesity is promoted by an undersupply of calcium, since this undersupply stimulates fat synthesis. It is also debated whether calcium plays a role in appetite regulation. Calcium citrate for good absorption in the body Calcium in the form of calcium citrate can be absorbed and utilized very well by the body because of the organic compound.Studies show that the absorption of calcium as calcium citrate is significantly better than the absorption of calcium from inorganic calcium carbonate. (Source: Jean A. Harvey M.D., Margaret M. Zobitz, Charles Y.C.Pak, Dose dependency of calcium absorption: A comparison of calcium carbonate and calcium citrate, Journal of Bone and Mineral Research, 1988) Unlike carbonates, which neutralize excess stomach acid, citrates are utilized in normal metabolism. If excess acid is present, this connects due to the different charges with the citrate and citric acid is formed, which is burned in the metabolism with the emergence of energy. Advantages of calcium citrate tablets from Fairvital may have significance for strengthening bones and maintaining high bone density may reduce fat absorption for a balanced acid-base balance well absorbable due to citrate form Pure substance, 100% calcium citrate per tablet vegan, gluten-free, lactose-free, fructose-free without magnesium stearate or silicon dioxide
