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.

Natural question is why not ask your doctor (you might be able to send a secure message through an online health portal)

I would just buy a bottle of B12 from a reputable brand on Amazon and follow the labeled dosing suggestion.

I agree about asking your doctor since he is the one who recommended them. If you have a shortage he may want you to take more than the normal daily dose.
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!

My doctor who recommended them told me to purchase ones that are enteric coated and molecular distilled. It definitely solved that problem.

Your doctor doesn’t fancy giving you a 3 monthly injection of it instead? Easier and more effective

Yes---TJ ones are molecularly distilled.

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.

And sometimes, it'll make your urine bright yellow, like fluorescent yellow.

What Mary2e said.

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.

correct- cyanocobalomin (the primary form available orally) is not well absorbed

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.
