Clinical background
Vitamin D is a fat-soluble, secosteroid hormone precursor. In humans, the most abundant forms are Vitamin D3 (cholecalciferol), followed by Vitamin D2 (ergocalciferol), known together as calciferol. Calciferol primarily undergoes hydroxylation in the liver to 25-OH Vitamin D (calcidiol), the major circulating form of vitamin D. The serum or plasma level of 25-OH Vitamin D is recognized as the most reliable indicator of vitamin D sufficiency. A second hydroxylation in the kidneys of a small amount of 25-OH Vitamin D produces 1,25(OH)2 Vitamin D (calcitriol). Calcitriol regulates calcium and phosphate blood concentrations through amongst other intestinal absorption.

Low 25-OH Vitamin D serum levels (lower than 10 ng/ml) have been found in 2-30% of adults within the European population [1]
Vitamin D deficiency was first discovered in the childhood disease rickets.
