Vitamin D: Classic and Novel Actions

Background: Classically, vitamin D has been implicated in bone health by promoting calcium absorption in the gut and maintenance of serum calcium and phosphate concentrations, as well as by its action on bone growth and reorganization through the action of osteoblasts and osteoclasts cells.

Consequences of genetic selection on metabolic regulation of skeletal health in broiler chickens

Improvements in broiler growth performance resulting from commercial selection are associated with poor skeletal health. Vitamin D3 plays an important role in Ca and P homeostasis and is essential for bone strength. Several studies have demonstrated that feeding biologically active metabolites of D3 [25(OH)D3 and 1,25(OH)2D3] can improve bone health.

1,25-Dihydroxyvitamin D3-glycoside of herbal origin exhibits delayed release pharmacokinetics when compared to its synthetic counterpart

Vitamin D requires two metabolic steps to become biologically active. In a first step 25-hydroxyvitamin D3 is formed, which acts as storage form. After a tightly controlled step in kidney the active metabolite 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) is formed. Because kidney is the relevant metabolic organ for this conversion, 1,25(OH)2D3 needs …

Vitamin D and the Immune System
It is now clear that vitamin D has important roles in addition to its classic effects on calcium and bone homeostasis. As the vitamin D receptor is expressed on immune cells (B cells, T cells, and antigen-presenting cells), and these immunologic cells are all capable of synthesizing the active vitamin D metabolite, vitamin D has the capability of acting in …
