Vitamin D3 Injection

Cholecalciferol at 50,000 IU/mL in an MCT oil base delivers the body’s preferred form of Vitamin D at therapeutic concentrations not achievable through oral supplementation. Supports calcium absorption, bone health, and immune function via IM injection.

Vitamin D3 Injection: Cholecalciferol 50,000 IU/mL in MCT Oil Base

Vitamin D deficiency affects a majority of the population — and oral high-dose D3 has absorption and compliance limitations. At 50,000 IU/mL in an MCT oil base, this injectable delivers the body’s preferred, naturally occurring form of D3 directly into the system via a single IM injection. No daily pills. No absorption variability. Immediate systemic availability.

Why Practices Add Vitamin D3 Injection to Their Menu

Bone health: Calcitriol (the active form of D3) increases calcium and phosphorus absorption from the gut — essential for bone mineralization and density maintenance.

Immune function: Vitamin D receptors are present throughout the immune system. Active D3 supports both innate and adaptive immune responses.

Muscle function: Supports normal neuromuscular function — deficiency is associated with muscle weakness and increased fall risk in elderly patients.

One-injection convenience: A single IM injection replaces weeks of daily oral supplementation — particularly valuable for patients with absorption limitations or compliance challenges.

Who It’s For

  • Medical weight loss and bariatric practices managing post-surgical nutritional deficiencies
  • Primary care providers correcting clinically confirmed D3 deficiency
  • IV therapy and wellness clinics offering comprehensive micronutrient protocols
  • Geriatric and integrative medicine practices supporting bone health and immune function

Pairs Well With

Practices offering Vitamin D3 Injection often combine it with Calcium Chloride Injection, Magnesium Chloride Injection, and B12 Injections as part of a comprehensive micronutrient and bone health protocol.

Precautions

Monitor serum 25(OH)D and calcium before and during treatment — at 50,000 IU/mL, Vitamin D toxicity (hypervitaminosis D) is a real risk. Signs include nausea, weakness, confusion, heart rhythm problems, and kidney damage. Adjust dosing based on lab values, not symptoms alone.

Contraindicated in hypercalcemia, hypervitaminosis D, sarcoidosis, hyperphosphatemia, arteriosclerosis with arterial occlusion, and known kidney stones. May interact with thiazide diuretics (hypercalcemia risk) and digoxin (cardiac arrhythmia risk). For IM administration only — not IV.

This is a compounded Rx product. Compounded drugs are not FDA-approved. Rx only. For use by or on the order of a licensed healthcare provider.

FAQs

Is a prescription required? Yes. Available exclusively to licensed healthcare providers and medical practices.

Why is Vitamin D3 in MCT oil? D3 is fat-soluble and requires a lipid carrier for effective delivery. MCT oil supports consistent bioavailability via IM injection.

What monitoring is recommended? Serum 25(OH)D and calcium before and during treatment. At this concentration, toxicity is a real risk — adjust dosing based on lab values, not symptoms.

What pairs well with Vitamin D3 Injection? Calcium Chloride, Magnesium Chloride, and B12 injections as part of a bone health and micronutrient protocol.
