Vitamin D is essential for maintenance of bone mineralization through the regulation of calcium and phosphorus homeostasis. Vitamin D also exhibits many non-skeletal effects, particularly on the immune, endocrine, and cardiovascular systems.
One of the minerals that is important in the regulation and processes of many body functions including bone formation, hormone release, muscle contraction, and nerve and brain function is calcium. If levels of calcium in the body are elevated above what is considered normal, this is referred to as hypercalcemia.he regulation of calcium is primarily controlled by vitamin D, calcitonin, and parathyroid hormone (PTH). 1  Calcitonin is produced in specialized cells in thethyroid gland. 2  Vitamin D is obtained through a process that begins with sun exposure to the skin.
