Hello,
Your Holotranscobalamin level of 17 pmol/L from November was indeed low (typically, levels below 35 pmol/L suggest a deficiency). You have already taken significant steps by completing a month of Neurobion Forte and high-dose Methylcobalamin (15,000 mcg).
Regarding your query about taking 'Carbamide Forte B Complex' for 120 days:
1. The Need for Re-Testing
Before committing to another 4 months of supplementation, it is clinically advisable to get a repeat
Vitamin B12 and Serum Homocysteine test done. * High-dose Methylcobalamin (15,000 mcg) is a very potent dose. It is possible that your levels have already normalized or even exceeded the required range.
Taking B-complex supplements for 120 days without knowing your current baseline can lead to unnecessary intake, particularly of Vitamin B6, which should not be taken in excess over very long periods.
2. Supplement Composition
B-complex vitamins are water-soluble, meaning the body usually excretes the excess. However, long-term use (like 120 days) should ideally be transitioned from "therapeutic" doses (high dose) to "maintenance" doses (lower dose) once your levels are stable.
3. Recommended Next Steps
Laboratory Check: Get a fresh B12 assessment to see how much of the previous supplementation was absorbed.
Identify the Cause: At 25 years old, if you have a recurring deficiency, consider if it is due to diet (common in vegetarians) or an absorption issue in the gut.
Maintenance: If your levels are now normal, you may not need a 120-day course. A shorter maintenance course or dietary adjustments might be sufficient.
Immediate Advice
You can certainly finish a standard 30-day pack of a B-complex supplement safely, but please pause and re-evaluate your blood levels before extending it to 120 days.
Summary: Your previous high-dose treatment was quite strong. Check your current B12 levels first to determine if a 4-month course is truly necessary or if you have already reached optimal levels.
