Description

What is Vitamin D3 (D320 — 20,000 IU/mL)?

Vitamin D3 (Cholecalciferol 20,000 IU/mL — high-concentration injectable) is cholecalciferol — C₂₇H₄₄O, MW 384.6 — at 20,000 IU/mL in oil-based injectable solution. Cholecalciferol is the natural form of Vitamin D3, converted to 25-hydroxyvitamin D3 (calcidiol) in the liver and then to the active 1,25-dihydroxyvitamin D3 (calcitriol) in the kidney. Calcitriol activates the vitamin D receptor (VDR) — a nuclear receptor regulating calcium/phosphorus metabolism, immune function, cell proliferation, and hundreds of downstream genes.
