A high-dose vitamin D3 injection designed to support healthy vitamin D levels, calcium absorption, bone health, and normal muscle and immune function.
Supports healthy vitamin D levels: Provides high-dose vitamin D3 for clinician-directed correction of inadequate vitamin D status.
Supports calcium absorption & bone health: Vitamin D helps maintain calcium and phosphorus availability required for normal skeletal mineralization.
Supports muscle function: Adequate vitamin D status contributes to normal muscle and musculoskeletal function.
Supports immune function: Vitamin D signaling plays an important role in normal innate and adaptive immune responses.
High-dose vitamin D: This formulation contains 50,000 IU of vitamin D3 per mL. Because vitamin D is fat-soluble and stored in the body, excessive or prolonged intake can result in accumulation and toxicity. Do not independently combine it with additional high-dose vitamin D unless reviewed by your clinician.
Calcium monitoring: Excessive vitamin D activity can cause hypercalcemia. Monitoring may be particularly important during prolonged high-dose treatment or in people with conditions affecting calcium metabolism.
Kidney health: Patients with kidney disease, a history of kidney stones, hypercalcemia, or disorders of calcium metabolism should discuss these conditions with their clinician before treatment.
Parathyroid & granulomatous disorders: Conditions affecting parathyroid function or vitamin D metabolism—including certain granulomatous disorders such as sarcoidosis—may require additional evaluation before high-dose supplementation.
Other vitamin D sources: Tell your clinician about all multivitamins, prenatal vitamins, vitamin D supplements, calcium + vitamin D products, fortified nutritional products, and other vitamin D injections you use.
Pregnancy & breastfeeding: High-dose vitamin D supplementation during pregnancy or breastfeeding requires individualized clinical assessment.
Potential side effects may include:
Excessive vitamin D exposure can cause hypercalcemia, with symptoms including excessive thirst, frequent urination, nausea or vomiting, constipation, weakness, fatigue, confusion, reduced appetite, dehydration, kidney stones, kidney dysfunction, and—in severe cases—cardiac rhythm disturbances.
Vitamin D3 supports calcium absorption, phosphorus regulation, bone mineralization, muscle function, immune signaling, and vitamin D receptor-mediated cellular signaling throughout the body.
Vitamin D helps the body absorb calcium and maintain appropriate calcium and phosphorus availability for normal skeletal mineralization. Bone health also depends on factors such as age, hormones, genetics, exercise, protein and calcium intake, medications, and overall health.
The laboratory test most commonly used to assess vitamin D status is 25-hydroxyvitamin D [25(OH)D]. Your clinician may use this test to evaluate baseline vitamin D status and response to supplementation.
Vitamin D increases calcium absorption. Because this is a high-dose formulation, excessive vitamin D exposure can cause hypercalcemia, particularly with prolonged use or in susceptible individuals. Calcium monitoring may be recommended during long-term treatment.
Yes. Vitamin D is fat-soluble and can accumulate in the body. Excessive supplementation can lead to vitamin D toxicity and hypercalcemia, which can affect the kidneys, heart, and other organs.
Additional vitamin D should be reviewed with your prescribing clinician. Vitamin D from multivitamins, prenatal vitamins, standalone supplements, fortified products, and other injections should all be considered when determining total exposure.
An injectable formulation may be considered when a clinician determines that intramuscular administration is appropriate for an individual’s circumstances. Injectable vitamin D should not automatically be considered superior to oral vitamin D.
No. This compounded Vitamin D3 Injectable formulation is not FDA-approved. Compounded medications do not undergo FDA premarket review in the same manner as FDA-approved drug products.
Vitamin D3 Injectable is a compounded high-dose formulation.
Vitamin D is a fat-soluble vitamin and hormone precursor essential for calcium and phosphorus regulation, bone mineralization, muscle function, and normal immune signaling.
This intramuscular formulation provides a clinician-directed option for vitamin D supplementation when an injectable form is considered appropriate.
This compounded Vitamin D3 Injectable formulation is not FDA-approved.
Converts in the liver into a form of vitamin D that circulates in the bloodstream and can be measured through blood testing.
Activates primarily in the kidneys, allowing the body to use vitamin D for essential functions.
Helps regulate cellular activity by interacting with vitamin D receptors throughout the body.
Supports calcium absorption and phosphorus balance, which are essential for strong bones, muscle function, and healthy nerve signaling.
Treatment should be individualized based on baseline vitamin D status, medical history, calcium balance, kidney function, total vitamin D exposure, and clinical goals.
Because vitamin D is fat-soluble and can accumulate in the body, high-dose supplementation should be used with appropriate clinical oversight.
All dosing should follow the instructions provided by the prescribing clinician.
Vitamin D3 Injectable contains cholecalciferol (vitamin D3), a fat-soluble vitamin and hormone precursor that is converted into active vitamin D metabolites that bind to vitamin D receptors (VDRs) throughout the body. VDR signaling influences calcium and phosphorus regulation, bone mineralization, muscle function, gene expression, and both innate and adaptive immune pathways. Adequate vitamin D status may support normal bone and muscle health, immune signaling, and broader metabolic and cellular function.
