How it works
Vitamin D3 is also known as the sun vitamin. It bears this name because the body produces it itself from the building block cholesterol. But the organism needs another important factor for this: sunlight. Only if enough surface of the skin is reached by UV radiation, this transformation takes place under the skin. Due to our modern lifestyle, which has shifted more and more indoors, and the extensive use of UV-blocking suntan lotions, people nowadays produce less and less vitamin D3 themselves. Especially in the cold season with few hours of sunshine, a vitamin D3 deficiency can easily occur. Vitamin D3 has a variety of functions in the human body. Probably the most important and best known are in the area of the immune system, muscle function and bones. Vitamin D contributes to a normal function of the immune system, a normal muscle function and the maintenance of normal bones. In the case of a pronounced and long-term deficiency, disorders can occur in these areas as a result. Like all vitamins, vitamin D3 is part of a complex biomechanism that does not function in isolation but together with other nutrients. For an optimal formulation, our vitamin D3 also contains vitamin K2, which also contributes to the maintenance of normal bones.
