What it is used for
 The working group of the Australian and New Zealand Bone and Mineral Society, Endocrine Society of Australia and Osteoporosis Australia state that a significant number of Australians are deficient in vitamin D.  Vitamin D3 is known to be pleiotropic, meaning it influences the expression of numerous/many genes throughout many/a range of systems and organs of the body.  Vitamin D receptors (VDR) are present in a wide variety of cells in numerous/many systems and most organs in the body (eg: heart, immune system, central and peripheral nervous systems, skeleton, brain, kidneys, skin, prostate and breast).  Older individuals/people may have an increased requirement for vitamin D3. [5a] The body?s ability to metabolise vitamin D to its active form may decline with age. [5b] Aging decreases the capacity/ability of the skin to produce vitamin D3 (because the concentration of 7-dehydrocholesterol in the skin decreases with age). [5c] Evidence suggests that by the age of 70yrs, the skin?s ability to produce vitamin D3 is reduced by approximately 75% compared to younger adults.  Vitamin D is required for healthy cell development, differentiation and maturation.  Adequate vitamin D is important for the maintenance of a normal healthy immune system.  1,25(OH)2D3 (calcitriol) interacts with immune cells such as monocyte-macrophages, antigen presenting cells, dendritic cells and lymphocytes and induces their differentiation. [9a] Vitamin D enhances/supports/improves the ability of the small intestine to absorb calcium from the diet. [9b] Adequate levels of Vitamin D are necessary for the maintenance of normal healthy calcium metabolism. [9c] Vitamin D is important/necessary/essential for the efficient utilisation of calcium by the body. [9d] Vitamin D is important for the maintenance of strong healthy bones.
