What is/are Alfa Calcidol?
Alfacalcidol (or 1-hydroxycholecalciferol) is an analogue of vitamin D used for supplementation in humans and as a poultry feed additive.
Alfacalcidol has a weaker impact on calcium metabolism than calcitriol, while having more potent effects on parathyroid hormone levels and the immune system, including regulatory T cells. It is considered[by whom?] to be a more useful form of vitamin D supplementation, mostly due to much longer half-life and lower kidney load. Used as a poultry feed additive, it prevents tibial dyschondroplasia and increases phytate bioavailability.
