Vitamin D3 (Cholecalciferol) is converted in the liver to 25-hydroxy Vitamin D3 (Calcidiol) and subsequently in the kidneys to the active metabolite, Calcitriol.
Calcitriol acts by binding to Vitamin D receptors (VDRs) throughout the body, increasing intestinal calcium and phosphate absorption necessary for:
- Bone mineralization
- Skeletal growth
- Neuromuscular function
- Immune regulation
Being fat-soluble, Vitamin D3 is stored in adipose tissue and muscle, with a long biological half-life of approximately 50 days.
D-20000 is indicated for:
- Treatment and prevention of Vitamin D3 deficiency
- Rickets and osteomalacia
- Osteoporosis and bone health support
- Calcium and phosphate absorption support
- Prevention of deficiency during pregnancy and breastfeeding
- Supportive therapy for immunity enhancement
- Maintenance of healthy bones and teeth
Vitamin D deficiency is more common in individuals with limited sunlight exposure or inadequate dietary intake.
