More about Alfa Calcidol

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.

Adverse effects

  •     Thinking problems, changes in behavior, feeling irritable;
  •     Urinating more than usual;
  •     Chest pain, feeling short of breath; or
  •     Early signs of vitamin D overdose (weakness, metallic taste in your mouth, weight loss, muscle or bone pain, constipation, nausea, and vomiting).
