Low in B12-how much should I take each day?

My B12 is 327 (range 200-1200).

I would like to start taking sublingual B12, but am unsure how much to take each day. I am very sensitive to the side effects of medicines/supplements/herbs and want to avoid possibly feeling any adverse affects, but want to take enough to make a difference.

What would the suggested daily intake of B12 be?
Thanks.

Re: Low in B12-how much should I take each day?

Your B12 levels are at the low end. I'm not sure exactly how much you ought to take daily, but sublingual B12 is an excellent idea.

I got my dad to have his B12 checked out and his was low at just 21 from the bottom, but his doctor simply blew him off and said he was fine. I got him taking one sublingual B12 each day and after 5 weeks his B12 has risen nicely. He continued taking it for a bit longer and is now not on the sublinguals, but ordinary multi B vitamin as a maintainance dose.

I also found out if your B12 is low that you can't abosrb folate very well so it's a good idea to look out for your B12.

So i'd say it's safe to start off with one tablet daily and after about a month get rechecked and see if it's gotten better. I'm not sure about side effects of B12 vitamins. If you are sensitive then maybe start off with half a tablet daily for a few days or a week, then take it up to one tablet daily.

As you are low in B12, there are chances you could be low in other things. A lot of people are low in ferritin and Vit D too so you might want to check those out also as most doctors don't routinely check these things.

Re: Low in B12-how much should I take each day?

Thanks, Audrey.
I began taking 500 mcg of B12, then 1000 mcg, then 1500 mcg. But I got very bad anxiety from it. I have some kind of sensitivity to B vitamins, and my doctors don't know why.
Maybe I do need to cut the sublinqual pill in half.
As you mentioned, I did get my D level checked. I am deficient in that and am on 10,000 Iu day.
I don't know what ferretin is and don't see it on my labs.

Re: Low in B12-how much should I take each day?

Ferritin is your iron stores. When your stores are higher you have plenty of ferritin to go round for things like energy, hair, skin and nails. Your iron stores are also utilised by things like bone marrow and your muscles. That would be a good one to check on so you know where you are at. You also need to be at the higher end of your lab range for ferretin too.

Has your doctor given any ideas on your sensitivity to the B12? You could query this on the Anemia board as a lot of people on there have issues with ferritin and B12 and there are some knowledgable people on there who might be able to help you out.
