How much B12 to take and how often?

I am pre-op but have been already taking vitamin b12 sublingual 500mcg once daily.  After surgery what is the correct dosage and mcg? 

It depends on your surgeon and nutritionist's requirements. Mine is 1000 mcg sublingual weekly.

Hey! Have you always taken B-12 since the beginning or did your Dr start you on it after a bad blood test? I have never taken B-12 in any format but several weeks ago when my blood work came back malnutritioned, I was put on foltrin which from my understanding may have a little b-12in it. I have always thought I needed more b-12 from being tired and so forth but I have never been given it but I also have never asked for it. Do I have to ask for it or is it soemthign that the Dr will just recommend if you really need it? Just curious.

Hey Misty, I've been on Foltrin since surgery. It is iron, b12 and intrinsic factor. The intrinsic factor enables the body to absorb the b12 in the stomach and digestive tract.

My doctor said one shot a month or one pill a week (even thought the bottle says once a week - he said it was a waste of money). He also said that there is no max so you don't have to worry about getting too much. Prayers and hugs, Sandi

Surgeon says once a week 500mcg, PCP says everyday 500mcg.  My PCP says everyone is different so to be on the safe side everyday.

That is really a question for your surgeon's office.
