Vitamin B12 level of 120 pg/mL is considered low, and supplementation is required. However, the exact number of injections and frequency is decided by a physician, as it depends on the cause of deficiency (dietary deficiency vs. absorption issues like gastritis, PPI use, gut disorders, etc.).
As a dietitian, I can guide you that B12 injections are commonly given in the following pattern (doctor decides the final protocol):
Loading phase: 1 injection every week for 4–6 weeks
Maintenance phase: 1 injection every month for 3–6 months
Along with injections, improving dietary intake is important.
B12-rich foods (vegetarian options):
Fortified cereals
Milk and milk products
Paneer, curd
Nutritional yeast
If non-vegetarian: eggs, fish, chicken
Next Steps
Please consult your physician to finalise the injection schedule based on your medical history and symptoms. Also, repeat
B12 levels after 6–8 weeks to monitor improvement.
Health Tips
Avoid self-medicating with injections. If you have gastritis, acid reflux, or take antacids frequently, discuss these with your doctor since they can reduce
B12 absorption.
