Vitamin D deficiency in the population
When do we speak of a vitamin D deficiency?
How much vitamin D a person has in their blood is usually stated in nanomoles per liter (nmol / L). It is difficult to give an exact limit under which health consequences occur. These long-term effects can also be influenced by other factors. The researchers speak of a deficiency from a level below 50 nmol / L vitamin D in the blood. The evidence suggests that at least this amount of vitamin D should be present to ensure long-term bone and muscle health.
Statistics on deficiency in the population
Since the importance of a sufficiently high vitamin D level is recognized in research circles, many studies have been carried out in recent years to find out how widespread vitamin D deficiency is in the population. Studies in Germany and Switzerland have shown that around 50 % of the population do not take in enough vitamin D. Because the deficiency is so widespread and has potentially far-reaching health consequences, researchers are even talking about a pandemic. The Swiss Nutrition Commission has therefore issued the recommendation to supplement vitamin D or to ensure sufficient exposure to the sun. More information is available in the Article "pill or sun".
