Vitamin D Injection
$200
A physician-supervised intramuscular Vitamin D3 injection designed for patients who do not respond to oral supplements or have genetic variations that slow Vitamin D activation (such as CYP2R1 rs10741657).
This therapy bypasses the digestive tract and liver conversion, delivering Vitamin D directly into circulation for faster and more reliable correction.
Vitamin D plays a crucial role in hormonal health, mood, immunity, muscle strength, inflammation control, and bone density. For many patients, especially those with genetic variations or malabsorption, an injection is the only method that produces noticeable improvements in energy, mood, and metabolic balance.
