B12 — Some Sweet Results

B12 — yikes! This vitamin is like the discussion on protein. Here are a couple of glaring examples, and, of the two presenters, the second one glows more nicely for me.

One link , titled “Symptoms of Vitamin B12 Deficiency”  ( https://www.youtube.com/watch?v=p0da1xrELcA&inf_contact_key=810c617563aa49fd33c5f37ec61df5887f90fe0ad494532c21a4686b506f9c6f ) comes at us from a deficient perspective giving what might cause a deficiency and a few of the problems deficiencies present  — a perspective, scientific, maybe, that says, before the first minute of over fourteen minutes of video, how only meat provides B12. The surprising part is yet to come, but it does, and it’s regardless of how much meat you’re eating, you could still have a B12 deficiency. How? Your parietal cells might not be producing enough HCI or intrinsic factor to break the B12 off of the eaten meat.  Often we don’t think of Oysters, Mussels, Salmon, Shrimp or fishy things as meat. The video makes it seem like the idea is beef or cow meat, and after many minutes of the video, we’re brought back to the idea to eat more meat. But I’m not sure how much, and if enough time goes by or enough information is brought in, it’s as if we’ve forgotten that regardless of the meat eaten ( kind or amount ) the absorption of B12 may not be happening. To actually end the connections to the deficiencies, a B12 supplement is introduced: methylcobalamin. Still, we don’t know how much of the supplement to take or even what form to take it in — is it a pill swallowed? Is it an injection? Whatever it is, he’s selling it, so that’s helpful, right? To make a little money for the insight, right?

Aagghh.  So we’re told about the deficiency quickly and with a put down “busting a lot of vegetarian bubbles.” The vitamin and its bioavailability are then spoken of in “adequate” amounts.

So what is adequate? We have to collect that information from somewhere other than the video presenting the deficiencies.

This site, http://www.todaysdietitian.com/newarchives/100112p15.shtml, provides the :

“Recommended Dietary Allowance (RDA) is 2.4 mcg/day.”

“Normal value ranges for vitamin B12 vary slightly among different laboratories and can range anywhere between 200 to 900 pg/mL. The general consensus is values less than 200 pg/mL constitute a B12 deficiency. Katherine Tucker, PhD, a professor of nutrition at Northeastern University in Boston, advocates that B12 adequacy is achieved with a serum level of at least 350 pg/mL.

But there are questions about the validity of the test via a serum level. Do they apply here? Of course validity applies, why wouldn’t it? Since the arguments on serum tests versus some other type of test are rather like a rabbit’s hole, let’s just consciously skip that darkness.

On a seemingly cheerier link, https://www.youtube.com/watch?v=iMr7bP5IUeE , a vegan example shows results of  >2000 H in a range limited between 254-1320 pg/mL.

So if meat and fishy meats are the only place to get B12, where’d the vegan get it?
How can a no meat, no fish, fully raw vegan have a level of B12 that is adequate?
In fact, the vegan’s serum shows the level of B12 to be greater than measurable?

Is greater than measurable good?

Yes!

How did the adequacy of the vitamin come about? The vegan has supplemented B12 twice in the last year. Of course, we don’t know how recent the last supplement was, and we assume the supplement wasn’t the normal battery of shots given everyday for a while and then monthly, then quarterly, etc., but we do know that the results in this and all the other categories are stellar.

I remain astonished.
