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.

Research Applications

Vitamin D Receptor (VDR) Research

Calcitriol-VDR nuclear receptor activation — gene expression, calcium metabolism, immune regulation

Calcium & Bone Metabolism

Intestinal calcium absorption, osteoblast/osteoclast regulation, and bone mineralisation

Immune Modulation

VDR in T-cell, macrophage, and dendritic cell function — innate and adaptive immunity

Deficiency Correction Models

Rapid repletion of severe Vitamin D deficiency in research models using high-dose injectable

25(OH)D3 Pharmacokinetics

High-dose D3 conversion to calcidiol — hepatic hydroxylation kinetics and serum 25(OH)D3 elevation

Frequently Asked Questions

How is this Vesta injectable supplied?
Vesta injectable solutions are supplied ready-to-use — no reconstitution required. Each vial contains the stated concentration in pharmaceutical-grade carrier (oil or aqueous). Draw using a sterile syringe appropriate for the solution viscosity.
How should this Vesta injectable be stored?
Oil-based solutions: store at room temperature (15–25°C), away from direct sunlight — do not refrigerate as cold temperatures can cause crystallisation. Aqueous solutions: store at 2–8°C. Properly stored, injectable solutions are stable for 2–3 years.
What purity is this Vesta injectable and how is it verified?
All Vesta injectable compounds are ≥99% pure by HPLC on every production batch, with MS-confirmed identity. COA is published on the product page and independently verifiable at verify.janoshik.com.
Peptide Research Tools: Use Vesta’s free peptide calculators — reconstitution, BAC water, dosing, half-life, and mixing charts.
