Does anyone know the typical dosage of B12 injectable in 'ml' and how often does it need to be given?

Hi,
I don't know what formula is used to determine a person's dosage. You might want to check with your medical team.
But, I've been prescribed Cyanocobalamin 1000mcg/ml, 1cc IM monthly.
Good Luck,
Mike

It depends on the B12 levels and what is causing it. People with really low B12 levels can get injections weekly until the levels go up, and then they slowly switch to monthly.

I do IV therapy for a living and use about 2 cc of b12 (2,000 mcg) twice weekly in the vitamin bags for my patients. Most do this for three months or more before they begin feeling better. I do not give b12 alone. I believe that b complex, vitamin c, magnesuim, and other nutrients are equalliy important for treating anemia. See if your physician will prescribe meyers cocktails instead of just b12...you will feel better much faster. Good luck!

Thanks to all who answered and thanks to Steph for your advice!
