Trying again to post this. Wondered if anyone knew any contraindication for using sublingual B12. I seem to recall a post somewhere that indicated that sometimes the sublingual form should not be used in cases of certain neuro diseases.
Anyone have any info on this?

If a person is hugely deficient and near death, a series of daily injections of cyano is required to prevent death. I see this in nursing homes frequently. By the time patients get to long term care they are very very ill...near death.

For those patients living a life...walking/talking breathing, etc, oral B12 (not necessarily sublingual) will do as well. Sublingual claims are not sterling. Most of what dissolves in your mouth is swallowed with your saliva.

Take at least 1000mcg (1mg) daily on an empty stomach, and you'll do as well as injectable. Studies have confirmed this.
If you are very low, you can do 5mg daily for a month or two...and decrease to 1mg daily after that. Don't assume you will be ever off it...it is most likely a lifetime thing. Whatever has caused your low readings is not going to change.

I do not know about a nuero problem, but if you have colitis, you might not be able to take the sublingual kind because it contains artificial sweeteners. If I can be of help, just let me know.

Best,

Silent

Thanks for trying. I appreciate the responses I have received. I guess I will just have to keep trying to find the info. I was able to learn a good bit by searching various sites, but not about a neuro contraindicaton for the sublingual form.
I guess I have learned that when I see something like that, I need to write it down.

One has to be careful on the net.
The only "negative" thing I can think of (and I did a Google search just now which showed nothing)
is the Pfeiffer research. People with methylation errors..
MAY have certain needs that differ from others.
Bipolar disorder for example is a methylation disorder it is thought.

Check the section on "methylation". Not many doctors agree with the Pfeiffer institute, however.

B12 is part of a group of B vits that work together. Ignoring the others, results in less improvement. B6 and folate are both needed to help reduce homocysteine, and if those are low, then homocysteine continues to damage the blood vessels.

The risk of B12 deficiency is high in older patients. That is why guidelines suggest all persons over 50 take a supplement now.

When you find what you are looking for, please post it here.
I'd like to see it.

This is the typical warning to NOT use FOLATE in B12 deficient patients:
Perhaps this is what you read?

I just recalled one thing I remember from a Mayo site
regarding the rare hereditary disorder called Leber's optic
neuropathy.

The Mayo site is not accurate on this subject. It was previously thought that B12 could not be used in these patients (who tend to all have low levels ) but newer information states that it is the CYANO form that should not be used. Recommended form for these patients is hydroxy or methyl.
I could not find any sites besides the Mayo one that says not to use B12. They ALL have B12 as treatments (except for the cyano version).

So if you find an older site or one that uses old information you might find Leber's listed as a condition to not use B12.
