Vitamin D - the sun vitamin

These symptoms can occur with chronic vitamin D deficiency:

  • fatigue
  • Decrease in cognitive performance
  • Depression
  • Muscle weakness
  • Susceptibility to infection
  • Decrease in bone density
  • Bone pain or fractures that do not heal well

Unfortunately, many of the symptoms are very unspecific and can occur in a variety of diseases.

A vitamin D deficiency usually occurs seasonally: in Northern and Central Europe, a large part of the population suffers from a seasonal vitamin D deficiency in the winter months. This deficiency is often compensated for in summer when those affected are sufficiently in the sun. This means: If you have your vitamin D level checked in winter and the value is too low, it does not necessarily mean that you have a chronic undersupply.

In our latitudes, the body can produce enough vitamin D between March and October - provided we are outdoors. If the need for vitamin D is met, a depot function is activated: fat and muscle tissue store the vitamin D and release it when needed. In medical terms, one speaks of a vitamin D deficiency when less than 25 nanomoles of the vitamin can be detected in one liter of blood. A severe deficiency is below 10 nanomoles per liter.
