Vitamin D is primarily known for playing a role in the body’s calcium content and thereby contributing to healthy bones.
A significant deficiency in Vitamin D can lead to deformation of the bones (rickets) in children and reduced bone density (osteoporosis) in adults. However, these disorders rarely occur in Germany. According to current insights, Vitamin D also plays a role in a well-functioning immune system. A lack of Vitamin D can lead to an increased risk of colds in people with a weakened immune system.
Vitamin D occupies a special position among the vitamins, as it can be formed by healthy people themselves in the skin with the help of sunlight. For that reason, it is often called the “sun vitamin”. During dark seasons and when people are not as often exposed to the sun, people should take extra care to ensure their Vitamin D supply through diet. Fish, eggs, milk and some vegetables (such as avocados) can provide additional Vitamin D.
