Vitamin B12
My doc recommended I start taking B12. Does anyone know the normal daily recommended dosage? I did some googling but wasn't familiar with the units that were recommended. For example, my fish oil are 1000 mg capsules. I didn't see that unit when looking at B12.
any help would be appreciated before I knock back 10 of 'em.

BTW--I could never take fish oil because I would burp that fishy taste all day. Someone recommended the Trader Joe Omega 3--they are marked odorless and they really are!

I asked my dad's doc, who also recommended he take sublingual B-12. He said it doesn't matter - whatever your body doesn't use leave through your urine. You can't take too much.

Looking here at the 2 supplements I have, they have between 2,500% and 16,000% (yes, not a typo) of the recommended daily allowance of the various B's.
You end up peeing most of it out.

Seems like a lot of variance. Our doc doesn't seem to think you can bring your levels up enough on pills and has the wife on a monthly shot.
Seems like the target level also varies a lot. *600+ picograms (I'm not sure if that is the right name) is what ours wants the level to be.

While I’m not a doctor, I’d warn that even water-soluble vitamins like B12 have an upper limit and it is in your best interest not to exceed that.
Tens of thousands of % DV is eyebrow raising no matter how much is ostensibly urinated away.
