I have been vegetarian since around this time last year and am making this transition into a fully vegan diet.



From what I have been reading, B12 cannot be obtained from any plant source (that can be efficiently absorbed by the human body).



The only way a vegan can obtain B12 is through a product fortified with B12, for example soy milk, veggie burger mixes etc.



My question is where does the vitamin B12 come from which is fortified into these products? And is this source of fortification vegan friendly?



Thanks for your help.

I was doing my own thing quietly and YOU are the one who created this post trying to make a big deal out of it. Keep flaming the fire. That must be what you want.

The B12 in fortified food is in most cases synthesized by bacteria in a lab.



In addition to fortified foods, you can also obtain B12 from supplements. Personally I would recommend taking supplements because they typically contain much more B12 than what you typically can get from fortified foods. But there is no harm in consuming fortified foods in addition, of course.

I no longer post here after VB was sold in 2012. (See my profile page for details.)

B12, in fortified foods, most commonly appears as cyanocobalamin, which is produced by bacteria. It's in a wide variety of foods, but usually cereals, rice/soy/hemp milks, juices/smoothies, and nutrition bars.



Supplementation is recommended, as absorption from food can be inconsistent. Find a chewable B12 supplement that can be fully dissolved under your tongue. This helps to maximize absorption.

Would something like this be a good choice? http://www.iherb.com/Jarrow-Formulas...enges/129?at=0

That looks good, but I've always heard cyanocobalamin is the best form. But it might just be the most common.



Anyone smarter than I know?

I'm also considering this product: http://www.sportyshealth.com.au/blac...ls-pr-782.html, might end up using this one because its reasonably cheap and available in Aus.

I use a sub-lingual B12. It's supposed to be better absorbed than going through your digestive track. You put a little pill under your tongue and leave it there for a little bit then swallow the remaining vitamin mush.

What does the sub-lingual type taste like? It doesn't take like any sort of prescription medication does it? I used to be forced to take some sort of sedative sub-lingually as a kid prior to surgery (had a ton of surgeries as a kid) and the taste would make me vomit. Now even as an adult if a pill were to get stuck in my mouth and start dissolving it'd probably make me vomit because I associate that taste with surgery and anesthesia (which also made me really ill). So, I've been afraid to try the B12 sub-lingually cause I'm afraid it'd taste like a prescription pill or something. Infact, I still don't take any B12 supplement, I've been drinking a glass of soymilk every morning to insure that I get some B12 in my daily diet.

The brand I buy tastes like candy, seriously. I love taking them!

They are vegetarian as well:

They're not bad, really. I've bought a few different kinds. One brand was all natural flavoring and stuff and actually was really tasty, very mild cherry. The one I have now is stronger tasting, and I find if I swallow the entire gloop at once its actually kind of gross, sort of in a children's tylenol way -- but if I swallow it gradually the taste doesn't bother me at all. I am REALLY sensitive to flavored medicines too. I'll swallow any pill over a liquid or chewable.

Thanks.



I take that one periodically and my B-12 levels are great. Since people are mentioning it, you can use it sublingually too if you want.

Thanks for the info Digger and Rabid_Child. I can certainly handle candy flavored stuff and even the gross children's tylenol flavor type stuff too. I'm going to get a bottle and start using them.

I have noticed that most of the supplements are 5000mcg even though the daily recommended intake is 100mcg, for example this: http://store.nexternal.com/shared/St...CS=vegane&All=



Should I look for a products that are more around 100mcg or are these others fine?

I bought the ones that Digger showed in his post on page 1 today. They are 500mcg. They also had 2,500mcg but I didn't figure I needed that much everyday. The taste isn't bad either.

Depends on whether you are deficient or just looking to supplement.



I'm not a nutritionist so keep that in mind, but from what I've researched it appears that oral B12 taken in doses of 500 to 1000 mcg are effective in correcting B12 deficiency even in subjects with absorption problems. Interestingly enough, one study I read found that there was no significant difference between oral and sublingual B12. I bought the sublingual anyway because they were on sale and I like the cherry flavor.



I've got a documented deficiency so I started out at 1000 mcg per day and after a few weeks I reduced that to 500 mcg. Depending on what my next bloodwork shows I may end up just taking it weekly. My doctor said there's no harm in taking this much and up to 2500 mcg is considered safe, but you should really discuss it with your own doctor just to be sure.



If you're not deficient, you only really need a few mcg per day.



Here's that study of sublingual vs oral:

There's also some good info in the wiki with sources at the bottom of the page:

Mine are a massive dose, but I don't take them every day. Just every couple of days or so. I haven't had any deficiency problems.
