"48.7 micrograms of vitamin B12 (812 percent), "

Actually, nutritional yeast does not contain B12. According to fatfreevegan.com and other sites, B12 is only made by bacteria and archaea. Therefore yeast, a fungus, does not make it.

Many times, but not all times, nutritional yeast has B12 and other things added to it. Whether it's fluoridated water, iodized salt, or hydroxocobalaminized yeast, why not let the people determine whether they want to take an additional substance? Why should yeast (or soymilk) be the product of choice to have B12 added to it? Why not oat bran? What if oat bran did, and you didn't want to get too much B12 and so therefore reduced your yeast intake, but come to find out the variety of oat bran stopped adding it? Or what if you switch brands of yeast and the new yeast had less, more, or no B12 added? I mean, too many people rely on assumed and presumed contamination of products and think it's obligatory. Just ask the fluoridation proponents!

Why does it need to be added to something? Why not take a supplement? I say let the people choose.

Some very good and relevant facts have been presented here in this topic. I will add an interesting one that follows along the line of kland's facts.

Seaweed has sometimes been claimed as a source of vitamin B-12. It can have a molecule similar to B-12, sometimes called B-12 "analogue." It does not produce the same results in humans as it might in a bacterium. We simply cannot benefit from it, and it may even block the receptor sites in our body from realB-12.

Let's hope they aren't fortifying yeast with a seaweed-derived B-12.

Here's an interesting link for more about it.

What about B-12 supplement tablets? Those real tiny ones?

If you are going to take B-12 supplements, just make sure that they are not of the "cyanocobalamin" variety. Get the hydroxocobalamin, even if it's more expensive. The absorption rates between the two dramatically differ. The body will utilize very little, if any, of the B-12 in the cyanocobalamin--which may help explain why it can be significantly lower in price. You get what you pay for seems true again.

And how do we know whether a B-12 supplement is synthetic or from animal sources? (I've never taken one, as I sometimes use yogurt and eggs, but sometimes my blood tests show macrocytosis.)

British produced MARMITE claims to be 100% Vegetarian and it contains B12. It is distilled from yeast. I have a slice of bread with it every morning, and blood test indicate I have no need of additional B12. But it might not work for you.

Hi pastor Johann, I don't have access to it here, and had never heard of it before. But, from what I read, the vitamin B12 is added to it during manufacture.

I'm going to call the factory for more information in the morning.

Cyanocobalamin is what is in the Marmite. This is converted in the body of most people into B 12 and millions of people use it that way, but it may not satisfy the consistency of certain individuals who require a special treatment. We are not all created equal and do not think the same way.
