Re: B12 Info/ in Louisiana

[Guest guest]

Thanks for sharing that, . It's so tough to know what's going to cause

cancer of be toxic these days.

I find it interesting that as a nurse, you were taught that B12 supps were

useless unless they were injection or sublingual.

After getting gastric bypass, we are told that B12 absorbs in the duodenum which

is now bypassed, so we have to use the sublinguals, and injections if necessary.

I never knew that it didn't absorb well in normal people, too.

The doctor may be one of those who questions the use of cyanocobalamin - the

most common form of B-12 administered by MD's. Studies have been conducted

that say it is metabolized into harmful cyanides. Cyanocobalamin must be

converted by the body into B-12 before it can be absorbed. Proponents of the

harmful cyanides theory usually endorse taking a more natural form of B-12,

methylcobalamin which is not supposed to metabolize into the harmful stuff.

When I was in nursing I had many patients who received routine doses of

cyanocobalamin. I've even given it to several of my family members on a

gradually decreasing basis: Every day for 3 days, every other day for 6 days,

once a week for 3 months. I've had patients who had taken it routinely for

years with no side effects.

We were taught that anything other than the injectable or sublingual

(under-the tongue) forms were useless, because B-12 would break down and become

useless in the presence of gastric enzymes and acids, and that there was no

cumulative effect, or problem with a toxic build-up of B-12.

So, I've been puzzled lately as to whether that information was wrong, or

whether a new, more stable form had been created, or whether vitamin

manufacturers were putting B-12 in supplements just to make a sale, knowing it

would never get absorbed.

I think it's the latter.
