My surgeon recommends 1000 mcg per week. Yesterday, my hematologist told me to start taking it every day (7000 mcg per week). Is that too much? What does your surgeon recommend? (Btw-I see a hematologist so that she can keep a check on my iron levels. I had 3 iron infusions before surgery because my iron was low). I have been taking it via lozenges (sublingual).

Thank you for your help!

I don't remember what my surgeon's starting recommended dose was (and that is all they are... recommended STARTING points, to be adjusted based on your individual lab results), but I have been taking 5000mcg sublingually once a week for several years now.

I take 1000 mcg by injection once a week. If you are using a sublingual, the ASMBS recommends 500 mcg a day, if that helps you. But in the end, it should be based on your labs. What's your B12 level?

I don't know my B12 level. They haven't checked it yet. I think it will be checked at my 6 month appointment. When I went for my 2 week appointment, they checked stuff like hemoglobin, kidney function, etc. That's great info about the 500 mcg per day. Thank you!! I definitely don't want a deficiency but then I don't want to overdo it either.

P.S. I have a 6 week appointment in 2 weeks-I am going to ask about checking my B12 level.

I was told to take one of the sublingual tablets every day. I think they are 1,000mg each.

I take 1000 mcg sublingually every day. I have a huge fear of B12 deficiency because of my years of working in neurology. Once the damage is done, it can't be undone.

That said, your dosage should be based on your labs, of course, as Kelly mentioned above.

I get b12 injections and mine is 1,000 MCG subQ 1x per month. My b12 labs always come back between 700 and 950

Funny this question came up today. I had my 1yr followup yesterday and my lab came back the my B-12 was >2000. Normal range is 211-911. LOL turns out that I was supposed to be taking 250 mcg twice a day but I bought a bottle of sublingual that is 2500 not 250. Dr and I had a good laugh over it and since I purchased a bottle of 250 count. I will be taking them 2x a week and not 2x a day. Moral of this story is my program suggests 500mcg daily.
