Hello,
I am Dr. Romain Rajan, General Physician (Ex Govt Medical Officer at RML Hospital, New Delhi), and your case has been allotted to me.
Thank you for your question. This is a very common and important doubt, and I will explain it clearly.
After completing a 3-month correction course of
Vitamin B12 and Vitamin D3, you should not stop them completely. Most deficiencies recur if maintenance is not continued, especially in adults with limited sun exposure or dietary gaps.
Vitamin D3
After correction, shift to maintenance dosing:
⢠Vitamin D3 2000 IU daily
OR
⢠Vitamin D3 60,000 IU once every 2 weeks
Also try to get 20â30 minutes of sunlight exposure at least 3â4 days a week.
Target
Vitamin D level should be above 35â40 ng/ml.
Vitamin B12
After correction, maintenance is required in most people:
⢠Methylcobalamin 1000â1500 mcg 2â3 times per week
⢠Long term or lifelong maintenance may be needed, especially if vegetarian or with acidity issues.
Target Vitamin B12 level should be above 400â500 pg/ml.
What you should do next
⢠Continue maintenance doses rather than stopping
⢠Repeat Vitamin D and B12 levels after 3â6 months
⢠Adjust dose based on reports and symptoms
Please remember that vitamin supplementation is often a long term maintenance process, not just a short course treatment.
