This metabolic step is very tightly regulated by blood calcium and phosphate levels through PTH and the phosphaturic hormone, FGF23, and constitutes the basis of the vitamin D endocrine system that is central to maintaining calcium and phosphate homeostasis (see discussion below on functions and physiological actions).

If you have risk factors for vitamin D deficiency, your provider may recommend checking your vitamin D levels regularly to ensure they’re in a healthy range. Get helpful tips and guidance for everything from fighting inflammation to finding the best diets for weight loss.Existing evidence suggests that vitamin D nutriture does not appear to affect the maternal processes of bone resorption that occur during lactation, nor its restoration post-lactation. Gene array studies in many cells and tissues show that calcitriol regulates several hundred genes throughout the body or as much as 5 percent of the human genome ( Pike et al. Anyone with a known vitamin D deficiency should follow their doctor's recommendations regarding supplements, evaluations and lab work to ensure the deficiency is corrected. The absence of any effect of sustained, generous vitamin D supplementation on fracture risk or bone strength in vitamin D deficient children is striking.

The pharmacokinetic consequence of the sum of these catabolic systems, as shown in studies in rats, is a slightly reduced half-life for 1α,25(OH) 2D 2 compared with 1α,25(OH) 2D 3 ( Knutson et al. indicated that serum 25OHD levels decrease after gastric bypass surgery, although the quality of the methods used is questionable. In essence, the potency of the two forms (as judged by the dose required to cure rickets) is assumed to be the same ( Park, 1940).Vitamin D orchestrates cell cycle progression via alterations in key regulators such as cyclin-dependent kinases, retinoblastoma protein phosphorylation, and repression of the proto-oncogene myc as well as by modulating growth factor receptor-mediated signaling pathways ( Koga et al. This is a major global health issue, as childhood fractures can lead to life years of disability and/or poor quality of life. However, clinical trials designed to test whether vitamin D supplements can prevent bone fractures in children have not previously been conducted.
