B12 is practically impossible for the body to absorb by any other means.

Personally, I take a sublingual B12 on top of my multi-vitamins. You can

also get weekly B12 injections that are very effective!

So how do omnivores get it from animal products? <puzzled>

Do you have any sort of reference that shows that only sub-lingual B-12 is

absorbed? I read the Vegan Outreach site after I posted and while I found

they listed sub-lingual B-12 as optimal they also endorsed other forms of

B-12 supplements including multivitamins and fortified foods. I've been a

vegan for 13 years without using sub-lingual B-12 more than a handful of

times and haven't had any problems (which isn't scientific proof of

anything, I admit).

Interesting point Hadass, but throwing logic around will do you no good.

Here's the basic answer to your question:

 

·        Vitamin B12 is composed of a complex tetrapyrrol ring structure

(corrin ring) and a cobalt ion in the center. It is also known as cobalamin.

* Vitamin B12 is synthesized exclusively by microorganisms and is found in

the liver of animals bound to protein as methycobalamin or

5'-deoxyadenosylcobalamin.

 

·        The vitamin must be hydrolyzed from protein in order to be active.

Hydrolysis occurs in the stomach by gastric acids or the intestines by

trypsin digestion following consumption of animal meat.

* The vitamin is then bound by intrinsic factor, a protein secreted by

parietal cells of the stomach, and carried to the ileum where it is absorbed.

* Following absorption the vitamin is transported to the liver in the blood

bound to transcobalamin II.

 

My understanding of the use of sublinguals or oral delivery drugs is that the

saliva helps break down water soluble vitamins and there is direct absorbtion

into the blood stream through the mucous membrane in the mouth or nose. The

direct absorbtion is supposedly more efficient than going through your

digestive system to you liver and then your blood stream. Less vitamin is

destroyed in the process and it is active in your system more quickly.

 

Hope this helps thoroughly confuse everyone.

I never worried about myself or my husband and our B12

intake since we were brought up as meat-eaters we

probably had enough stored in our bodies that it

wouldn't cause a problem. I started researching

things when I got pregnant since it seems still

unclear whether the unborn child or nursling can get

the B12 from the mother's stores or if they only get

what the mother intakes daily. I decided it wasn't

something that I wanted to risk. Also, as I think it

stated in the Vegan Outreach article, B12 deficiency

does not show up right away and some of the effects

are irreversible.

Does this suggest that lacto-ovo vegetarians, such as myself, are also

at risk for B-12 deficiency? Also, where do the cows and chickens get

it from? *They* don't (in their natural state) eat meat ...

OK, I'm willing to believe that sublingual is more efficient. But if I

take a multivitamin every day, won't I get *some* B-12, even if the

delivery is poor? The RDA for B-12 is pretty low as I recall ...

 

Thanks for the explanation!

As I pointed out in a previous post, I don't rely on old B-12 store from

my meat-eating days. I believe very strongly in B-12 supplementation. I

just get mine from a prenatal multivitamin and fortified foods, not

sublingual B-12. I was not questioning the need for supplementation, only

the assertion that sublingual B-12 is the only way to do it.

Okay, this is how much I can tell you. B-12 is present in all animal

products including dairy products so lacto vegetarians typically have nothing

to worry about.

 

Cows themselves have different nutritional needs than humans and different

vitamins and proteins that would be classified as " essential " (meaning not

produced by the body and must be consumed). Cows produce B-12 in their

digestive track, as do humans by the way. I believe that it is actual

digestive bacteria & enzymes that produce it. Unfortunately human production

of B-12 occurs low in the large intestine and is usually not absorbed

sufficiently. I haven't got a clue what the deal is with chickens.

 

The absorbtion difference between sublingual and pill is a matter of

percentages, you do still absorb B-12 from a pill or liquid vitamin

supplement, just in lower percentages compared to what you swallowed.

 

B-12 requirements are very low and a normal healthy body usually has up to a

6 year supply.

 

Just for the record, I have a degree in fine art not nutrition, and vouch for

the veracity of absolutely nothing I say (on pretty much any topic).

[Guest guest]

Actually a good friend of mine went to the vegetarian nutrition conference

at Loma Linda university this year and got all the late-breaking news about

b12. I will repeat here what I remember him telling me he learned from the

conference.

 

MOST people can absorb the b12 they ingest from a multivitamin. However,

about 3-5% of people have a problem getting it that way. Those people need

to get it either from a sublingual pill or from a CHEWABLE pill. Either

would work fine. They know this because they tested it in people with

elevated homocysteine, which is one marker of low b12 levels, and b12 blood

levels, before and after taking multivitamins and later, chewable b12 pills.

 

Here's the rub: there's no way to know if you're one of those 3-5% until

you've had some sort of deficiency. Fortified foods similarly may work for

the majority, but not for a small minority, esp if they're not taking in

enough of them. With the chewable kind, you don't even need to take the

whole pill, just break it into pieces and take a piece per day or couple

days. Check the amount in one pill - it will be a lot. It should thus be

very cheap to supplement yourself and your child with a crushed pill. One

bottle of cewable b12 can last a long time.

 

So based on what I learned from him and from another list of scientists and

researchers I'm on, I intend to put a little bit of powdered chewable b12

in my baby's food. As for the breast milk issue, the current research tells

us that for some weird reason, stores of b12 do not appear to be accessible

for breastmilk production. Only the b12 the mother currently ingests seems

to be found in the milk. Yes this is quirky and unlike other nutrients,

where the mother's reserves will be depleted for the milk. But there are

very many documented cases of infants with b12 deficiencies whose mothers

were exclusively breastfeeding but not taking any supplements or fortified

foods.

This may go against what we were told before - I know I was surprised, but

it's what the latest research is telling us. b12 absorption has a lot of

individual variation, among omnivores and veggies alike. It is now standard

advice for people over 50 or so to supplement with it, regardless of their

diet. I think we should take it seriously.

I realize a lot of people have contributed helpful information regarding

vitamin B12 , but for what it may be worth, here's my input. Having just

completed my MS in nutrition, this is extracted from a research paper I did this

semester on the topic of adequate and appropriate nutrition for vegetarian and

vegan infants, children, and adolescents. I hope it gives a new perspective on

what everyone has said and may be just the slightest bit useful:

 

The primary source of vitamin B12 is food of animal origin and, consequently,

deficiencies in vegetarians, especially vegans, can develop quite easily. This

poses significant danger to those whose diets are unsupplemented or unfortified.

Substantial research has shown plasma B12 concentrations to be lower in both

vegans and lacto-ovo vegetarians compared to the general population.

Furthermore, vitamin B12 detected in plant foods and in spirulina, sea

vegetables, tempeh, and miso has been found to be an inactive analog that is of

no use to the body and may actually interfere with the active form of this

vitamin. Inadequate plasma levels of vitamin B12 can result in megaloblastic

anemia (large red blood cells) and inhibition of cell division as well as a good

chance of developing pernicious anemia and severe neurological damage. Other

signs of a deficiency include poor growth, weakness, fatigue, loss of vibratory

and positional sensations, and a range of psychiatric disorders. Indeed, studies

have shown that a lack of B12 in infants and toddlers cause failure to thrive

and delayed cognitive and psychomotor developments. This is especially likely to

occur in infants who are exclusively breastfed by vegetarian mothers who either

have undetected pernicious anemia or have low serum levels of vitamin B12. A

significant complication, particularly in older vegetarian children and

adolescents, is the fact that they eat larger quantities of leafy green

vegetables which contain another B vitamin, folate. Folate can mask the symptoms

of pernicious anemia, which is often the earliest indication of a B12

deficiency, thereby allowing any neurological damage to progress unchecked.

In regard to breastfeeding, there appears to be debate over the availability of

maternal B12 stores. Thus, it is important for the breastfed infant to receive a

supplement from birth unless the mother’s diet is regularly fortified, as

infants require a sustained intake of this vitamin to support their rapid

growth. As toddlers are weaned from either breast milk or formula, it is

essential that adequate sources of foods containing, or fortified with, vitamin

B12 as well as calcium, iron, zinc, and vitamin D be introduced, such as vitamin

B12–fortified soy milk.

Hi Lionsima -- it was wonderful to see that my lengthy dissertation on the

subject was actually read! Thanks!

First off, let me just reassure you that severe B12 deficiencies -- and their

symptoms -- are uncommon in developed countries where families have both the

financial means and the access to healthful foods and adequate quantities of

them. My guess is this includes you. As your children consume dairy products, a

B12 deficiency should not likely be of concern. In addition, to your children's

advantage (and to you and your DH), it seems you are cognizant of nutrients that

are likely to be precarious in the vegetarian/vegan diet and take a

multivitamin, which is also a reliable source of bioavailable B12. As for your 3

y/o, I would recommend the multivitamin and multimineral supplement I give my 10

month old. It is a completely vegan powder and can easily (and covertly) be

mixed into your child's food. I order it through a company called Shaklee. It is

called " Vita-Lea for Infants & Toddlers " (toddlers being 1-4 y/o). Shaklee can

be found on the web at http://www.shaklee.com/ . Their products are not sold in

any stores so you can only get them through a distributor.

So, based on the information you gave me, it seems as though your family is

adequately covered in the B12 department and I don't think you need to worry

about the occurrence of any deficiencies, especially when you consider one

doesn't need an especially large dose of this vitamin. However, to further ease

your mind, B12 can also be found in foods such as fortified ready-to-eat

breakfast cereals, some meat analogs, fortified soy milk or rice milk, and

tempeh, just to give a few examples. I hope this answered your question and

helped.

As for the leafy green vegetables....don't give up and, in the meantime, the

important folic acid (another B vitamin) can be found in plenty of other foods

your children are happily consuming!

 

PS -- No apologies necessary and, since I am Jewish, no translations needed

either!

 

Take care :-)

Interestingly severe B12 deficiencies are uncommon in third world countries

where agri-business, pesticides and an obsession with sterilizing everything

associated with food has not destroyed the natural occurrence of B12 by

bacteria in soil. Vegetarians in undeveloped areas of China get their B12,

not in their fruits and vegetables, but on them according to the findings of

I apologize for any confusion regarding B12. I suppose I should have included a

disclaimer in that, for the most part, the literature I read (all articles from

peer-reviewed scientific journals such as The American Journal of Clinical

Nutrition, and The Journal of the American Dietetic Association and so forth)

that cited food sources for B12 did include tempeh. On the other, that was

completely contradicted by other articles which stated: " vitamin B12 detected in

plant foods and in spirulina, sea vegetables, tempeh, and miso has been found to

be an inactive analog that is of no use to the body and may actually interfere

with the active form of this vitamin. "

So, basically, I guess the jury is still out and, until further research is

done, it is best to take a vitamin supplement (or even most, if not all, protein

and energy bars have B12 ) as there certainly is no debate that one does need

B12 and a supplement is a reliable, bioavailable source.
