5. In the 19th century, vitamin D deficiency was identified as the cause of the rickets
epidemic in children living in industrialized cities.
This discovery led to the fortification of various foods, and the resolution of a major
health problem associated with vitamin D deficiency.
However, recent studies have shown that vitamin D deficiency and insufficiency are
associated with other pathologic conditions in persons of all ages.
Vitamin D plays an important role in skeletal development, bone health maintenance, and
neuromuscular functioning.

deficiency and to support optimal health.

Malabsorption: Coeliac disease, Cystic Fibrosis
Renal disease (low 1,25 dihydroxy vitamin D- the most active form)
