Vitamin D

Vitamin D is a vital substance that acts as a prohormone. Vitamin D is usually synthesized by exposing the skin to sunlight. Especially in the winter months, sun exposure may not be sufficient to ensure optimal vitamin D status. This should be avoided because vitamin D is important for a normal immune system, normal calcium levels in the blood, normal muscle function and contributes to the maintenance of normal bones and teeth. What can I expect from vitamin D? Studies show that vitamin D deficiency is widespread. Modern lifestyles and the fact that people nowadays spend most of their time indoors and hardly any time outdoors contribute to vitamin D deficiency, especially in the winter months. For this reason, the German Nutrition Society (DGE e.V.) increased the reference values for vitamin D in 2012 and confirmed the usefulness of taking a vitamin D supplement to cover the requirement. If you are not sufficiently exposed to sunlight, you should also consider taking vitamin D in tablet form to meet the requirements of this vitamin, which is important for bones, teeth, muscle function, calcium absorption and utilization as well as the immune system. Functionality and mode of action of vitamin D? Vitamin D (cholecalciferol) is not actually a vitamin, but rather a prohormone that can be synthesized by the body from sunlight. Vitamin D plays a very important role in the calcium balance and bone mineralization. It contributes to the normal absorption and utilization of calcium (and phosphorus), which contributes to a normal calcium level in the blood and the maintenance of normal bones and teeth. The role of vitamin D for the immune system and muscles is also important. It contributes to a normal immune system and the protection of cells from oxidative stress as well as to normal muscle function. Vitamin D also has a function in cell division, a basic requirement for the formation of new muscle cells and consequently muscle growth. In addition to endogenous synthesis from sun exposure, vitamin D can also be obtained from foods such as oily fish. In many countries - unfortunately less so in Europe - vitamin D is also added to foods such as milk in order to meet the population's requirements and minimize deficiency symptoms. Peak Vitamin D is high-dose vitamin D (2000 IU per tablet), which can make an important contribution to ensuring an optimal supply of this important "vitamin" at any time of year.
