Calcitonin is a hormone that functions to reduce blood calcium levels.itamin D acts also to increase blood concentrations of calcium. It is generated through the activity of parathyroid hormone within the kidney. Far and away the most important effect of vitamin D is to facilitate absorption of calcium from the small intestine.
Vitamin D deficiency leads inevitably to calcium and other mineral deficiencies Long lasting or chronically repeated 25OHD3 levels beneath 30 ng/ml (80nmol/L) result in compromised calcium absorption in the bowel, and inefficient fixation of calcium and phosphate, as well as all other minerals, stored in bone (4-10).
