Vitamin D is a somewhat special, fat-soluble vitamin, in the sense that it is the only vitamin that the body itself can make. Vitamin D is produced inside body via the skin when ultraviolet rays from sunlight trigger its synthesis. However, for people residing in high latitudes, having a dark skin color, older age, being inside a lot, living in smoggy environments the diet is important to get enough vitamin D. Sources of food which are high in vitamin d are scarce. >1 billion people in the world have low vitamin D levels. This is found in all ethnicities and age groups.
Sources of food high in vitamin D (per 100 gram):
Salmon 9 µg
Shrimp 3,8 µg
Sardines 12,5 µg
Egg 0,5 µg
Mushrooms 15 µg

The active form of vitamin D, calcitriol, has a broad effect on many body processes. This is also apparent from the multitude of tissues in the body in which the vitamin D receptor occurs. It is estimated that vitamin D regulates directly or indirectly, via activation of the vitamin D receptor, between 100 and 1200 genes.
