What forms of B12 supplement is more efficient?

I've been on Nexium medication. And I previously have high homosystein history. Therefore, I must have B12 supplement. Is oral B12 an effective suuplement?

  Hi, it really depends on how ow ur levels are and how much of a dosage u need...sometimes a shot is more effective again, given the amount u need to raise the levels...another good way to get B12 into the system fast is sublingual...u place it under the tongue and allow it to dissolve.

Check with ur Dr as to what dosage and type will be best for u.
