Your B12 level of 144 pg/mL is deficient (normal range is usually >200–300 pg/mL depending on the lab;
Next Steps
1. Continue Meganeuron OD exactly as prescribed
• Usually 1 tablet daily after food (or as doctor advised).
• Take consistently — do not skip days.
2. Retest B12 level after 6–12 weeks of daily treatment
• Goal: >400–500 pg/mL (to rebuild stores)
• If level rises well and symptoms improve → continue oral maintenance (500–1000 mcg daily or every other day) lifelong if diet is low in B12.
3. See your doctor again if:
• No improvement in fatigue/weakness after 6–8 weeks
• New/worsening neurological symptoms (tingling, numbness, balance issues)
• Then ask about switching to B12 injections (cyanocobalamin or methylcobalamin 1000 mcg IM weekly × 4–8 weeks, then monthly).
Health Tips
• Take Meganeuron after food to reduce stomach upset (rare with methylcobalamin).
• Eat B12-rich foods if non-vegetarian: eggs, dairy, fish, chicken, liver.
• If vegetarian/vegan → continue oral supplement lifelong (diet alone cannot correct deficiency).
• Avoid alcohol excess — interferes with B12 absorption.
• Drink plenty of water and stay active — helps overall energy while B12 stores rebuild.
Most people with levels around 144 feel significantly better within 4–12 weeks of consistent oral treatment.
Oral is enough for you right now — no need to jump to injections unless symptoms are severe or don’t improve.
If you share your exact symptoms (how bad is fatigue? any tingling/numbness?) or doctor’s full prescription dose, I can guide more specifically.
Take care — you’ll start feeling better soon

You have Vit B12 deficiency.
If you are not experiencing any symptoms due to this, then you can carry on with the oral medication.
Otherwise Injectable correction of Vit B12 is recommended.
