Vitamin B12 Injections
Energy and nervous system support for low B12.
Vitamin B12 supports red blood cell production, nerve function, and energy metabolism. Deficiency is common in patients following plant-based diets, taking certain medications, or with absorption issues, and injections bypass the digestive tract entirely.
What it supports
- Supports energy metabolism
- Supports nerve and red blood cell health
- Useful when oral supplements are poorly absorbed
Who it may suit
- Patients with documented or suspected low B12
- Plant-based eaters and patients on certain long-term medications
- Patients wanting a quick, routine wellness visit
What to expect
B12 injections are quick and given intramuscularly. Lab work can confirm deficiency when appropriate, and your provider will recommend a schedule based on your labs, symptoms, and goals rather than a fixed package.
