Who should measure their vitamin D level?

Only very small amounts of vitamin D are absorbed through food. Up to 90% of vitamin D is produced by the body itself, namely in the skin as a result of sunlight. However, due to our modern lifestyle, especially due to too little time spent outdoors and the use of high sun protection factors, the body’s own vitamin D production is no longer sufficient in many cases. A deficiency is therefore no longer restricted to risk groups such as small children, pregnant women, people with dark skin and the 50+ group of people, but can affect anyone. A vitamin D deficiency can be diagnosed particularly well after the winter period when there is little sunshine. When taking vitamin D preparations, it is recommended to check their effectiveness at certain intervals. This allows an optimal adjustment of the dose to seasonal fluctuations in light conditions and individually varying needs.
