SWISS CHEESE has the POWER of B12 making bacteria!

Famously, vitamin B12 foods are dairy, eggs, fish, seafood, and meat. What isn’t well known is that vitamin B12 originates exclusively with microorganisms, that is, bacteria. When you eat a food like Swiss Cheese with live, B12 making bacteria, you enrich your digestive system with an ongoing source of vitamin B12.

Equally, Asian black tea that is fermented with B12 making bacteria not only contains Methylcobalamin, the active form of vitamin B12, but also the live bacteria, yet Asian black tea is seldom included in a list of vitamin B12 foods.

Mushrooms, some seaweed, soil, in fact almost everything around us contains the bacteria that originate B12.

On the other hand, cereals like Fruit and Fiber are among vitamin B12 foods only because B12 has been added in the commercial, cyanocobalamin form.

1/8/2015 ~ I began ordering the Swiss cheese, Emmentaler, so I could add bits to the yogurt I make in the hope of increasing the amount of B12 it contains.

It seemed to work in that the yogurt culture was very bubbly, which gave the clear impression that the B12 making bacteria, Propionibacterium freudenreichii, were alive, well and at work. The B12 making bacteria, you see, are responsible for the “bubble” holes characteristic of Swiss cheese. The holes are a result of the bacteria releasing carbon dioxide.

Next, I decided to test eating Emmentaler regularly. I wanted to see if the Propionibacterium freudenreichii in it would increase the range of vitamin B12 foods for me. My thought was that the Propionibacterium freudenreichii bacteria would make B12 from things I eat, like tomato paste. Ordinarily, fruits and vegetables are not among vitamin B12 foods.

The American Swiss cheese I just ordered doesn’t have holes, so I’m not sure it has the actual bacteria. On the other hand, moons seem to be coming back on my fingernails. The question is, will my moons actually return or are they emerging in the brief respite from stress I’ve been enjoying?

1/9/2015 ~ It turns out the Swiss are aware of imitators. Given that there are imitators, I wonder how much of an imitation the Emmentaler I bought is. Was it made with pasteurized milk? Does propionibacterium freudenreichii grow less well in pasteurized milk, thus reducing the number of holes, or… holes in their entirety.

Swiss Seek to Protect Emmental

Genuine Emmentalers from Switzerland wear the full moniker of Emmentaler Switzerland AOC (the word “Emmentaler” itself is not protected, meaning that cheeses with that label can come from anywhere).

Swiss Emmantaler is made from raw milk—an ingredient that is part of their centuries-old and now legally enforced recipe for Emmentaler Switzerland AOC. Raw milk’s native microflora and enzymes work in tandem with cheese cultures to develop the fullest flavor spectrum.

The FDA requires that cheeses made from raw milk be aged at least 60 days. Thus, production costs less when pasteurized milk is used and aging time cut.

The age of Swiss cheese is directly related to its most recognizable feature: the holes.

These “eyes” are gas bubbles that form inside the cheese wheels when cultures (that is, the bacteria) consume lactic acid in the cheese and release it in the form of carbon dioxide.

Young cheeses might have gaps the size of peas, whereas the craters in Emmentaler Switzerland AOC can grow as large as walnuts. Among vitamin B12 foods, Swiss cheese and authentic Emmentaler are my favorites.

3/4/2015 ~ My moons are definitely returning.

Best of all, despite a week of extreme cold because the vinyl covering my kitchen skylight came partially down, my moons have not disappeared. That seems to indicate healthy vitamin B12 levels deeper than those achieved by B12 shots or lozenges, both of which raise the level primarily in blood.

I’m eating about 6 ounces of Emmentaler cheese a day.

Just to be clear, I’m also using some Methylcobalamin lozenges. They on their own, however, have not, over the years, been able to restore my moons in a significant, long lasting way.

Because the B12 content is so low in less famous vitamin B12 foods, it is important to recognize that the content may vary greatly depending on where the food was grown.

 Batabata-cha ~ Fermented Japanese Tea

Batabata-Chabatabata-cha-in-packaging

This is pretty technical, but so impressive, given that the operative word is,  Authentic.

A Japanese fermented black tea (Batabata-cha) contained a considerable amount of vitamin B(12) (456 +/- 39 ng per 100 g dry tea leaves and 2.0 +/- 0.3 ng per 100 mL of tea drink). A corrinoid compound was partially purified and characterized from the tea leaves. The patterns of the purified compound by the silica gel 60 thin-layer chromatography and C18 reversed phased high-performance liquid chromatography were identical to those of authentic vitamin B(12).

When 20 week old vitamin B(12) deficient rats, which excreted substantial amounts (about 250 mg/day) of methylmalonic acid in urine as an index of vitamin B(12) deficiency, were fed the tea drink (50 mL/day, 1 ng of vitamin B(12)) for 6 weeks, urinary methylmalonic acid excretion (169 +/- 29 mg/day) of the tea drink-supplemented 26 week old rats decreased significantly relative to that (250 +/- 32 mg/day) of the deficient rats.

The results indicate that the vitamin B(12) found in the fermented black tea is bioavailable in mammals.

Vitamin B12 foods include Fermented Soy

In view of the the fact that soy is a popular food (sadly much soy grown in the U.S. is GMO) and the fact that soy itself contains no vitamin B12, researchers fermented soy using Lactobacillus reuteri CRL 1098, a bacteria known to produce an active form of vitamin B12. The resulting soymilk beverage was fed to animals (pregnant females and their offspring), and not to similar animals in the control group. 

At the end of the trials, females and their corresponding offspring were sacrificed and studied. The researchers found that drinking the fermented soymilk prevented the development of all symptoms associated with nutritional B12 deficiency both in females their offspring. Soybean-based functional food with vitamin B12-producing lactic acid bacteria by Verónica Molina, Marta Médici, Graciela Font de Valdez, and María Pía Taranto.

Add B12 making bacteria to yogurt you make

It’s easy to make yogurt, which is one of the most convenient vitamin B12 foods. You can increase the amount of vitamin B12 in the yogurt you make quite easily by adding a bit of Emmentaler cheese while preparing your yogurt mix. The yogurt tastes good, not cheesy. Yogurt and Vitamin B12 ~

B12 Status in Long-term Vegans

Rauma et al. (1995, Finland) examined the B12 status in long-term adherents of a strict uncooked vegan diet called the “living food diet”…The 16 vegans consuming nori and/or chlorella seaweeds had serum B12 levels twice as high as the 5 vegans not using these seaweeds. Rauma et al. concluded that some seaweeds consumed in large amounts can supply adequate amounts of bioavailable B12. However, they also thought the high levels of iodine in the seaweeds would be detrimental over time. Vitamin B-12 status of long-term adherents of a strict uncooked vegan diet, Rauma, 1995

An indication of low vitamin B12

One indication that you might be significantly low on vitamin B12 is the appearance of lines or ridges on your fingernails, and the disappearance of the moons at the bottoms of your fingernails.

There are many common things, not to mention stress, which reduce the amount of B12 you get from your food. Some of these things also deplete the B12 you have stored in your body. (For your body to work properly you need B12 in all of your muscle tissue, according to the neurologist I was seeing when my B12 problem was first diagnosed.)
Jarrow Methyl B12, 5000mcg, 60 Lozenges

Jarrow Methyl B12

There are two forms of Vitamin B12 commonly available for purchase. It’s a good idea to learn to distinguish between them, since one form, Methylcobalamin, is the active form of B12 and acts both more quickly and more efficiently, the other is Cyanocobalamin. Methylcobalamin gives far better results than the form which is simply labeled “B12”.

Because vitamin B12 foods have so little B12 in them, (there’s more than enough if you aren’t under a lot of stress, I don’t want to give the wrong impression) I’m going to talk about the amount of B12 in supplements. 1,000 mcg (micrograms) is the same as 1 mg. Dissolving a 1 mg Methylcobalamin lozenge under your tongue every day for a month is the same as having a B12 shot a month. A 5 mg Methylcobalamin lozenge dissolved under your tongue every day for a month will equal 5 B12 shots a month.

So, How much Methylcobalamin to use?

Let me give you an idea of how much B12 is generally prescribed by doctors: replacement therapy typically begins with a shot a day for a week or two, followed by a shot every week for a few weeks, after which there is a shot a month, generally for life, for “maintenance.”

To equal a shot a day, you would need to dissolve 30 mg a day of Methylcobalamin lozenges under your tongue. That would be 6 of the 5 mg lozenges a day.

Just to be clear, it appears that once there is a B12 deficiency, the amount of B12 needed to recover is not available from food.

When I was having a shot a day my peripheral neuropathy went away.

  1. I was reading that you received a shot a day for your periferal neuropathy. How many days did it take? i have just been diagnosed after 4 long painful years. i would like to be able to tell my dr how long it took for you. just to have some perspective. Thank you

  2. Hi Mary Pat,




    I don’t think doctors are even remotely interested in things people find on the internet. In fact a lot of people have told me that telling their doctors about things like that has made the doctor Less helpful.



    The holistic doctor that gave me the prescription for 12 bottles of cyanocobalamin, each containing enough for 30 shots, wrote me the prescription months before I began using it. I thought she’d made a mistake because I’d never heard about shots being that frequent.




    When I had tetanus I began using the prescription. I kept track of the results in my Tetanus Journal. I don’t remember exactly how long it took for the peripheral neuropathy to go totally away. I’m sure it was several weeks. I don’t remember if it was a few months, or longer, or less than several months. Tetanus Journal ~ Read more.




    I do know that last year when I stopped eating GMOs and began eating veg out of my garden without washing them, since cobalamin comes from microorganisms in the air, ground, etc. I began using far fewer methylcobalamin lozenges. It was fine, too. Except that last winter I forgot that I wasn’t eating out of my garden, but rather, cans. So I should have begun using more lozenges. I didn’t. Pretty soon the neuropathy came back. Intensely painful burning, particularly on my right thigh.




    Over the last month I’ve been using 3 to 5 lozenges a day with the result that the burning happens only infrequently, and usually when there’s something stressful precipitating it.




    I feel sure that your peripheral neuropathy will go away.

  3. I have high b12 levels. .. 1350…what can I do to reduce this level and what if any are the negative effects of such a high level

  4. Hi Jo,

    1350 as a B12 level sounds high because in the US many labs and doctors accept 180 as normal.

    In Japan the lowest normal is 500-550 because levels lower than that are shown to be accompanied by some loss of mental abilities. What is a Healthy B12 Level? https://health-boundaries.com/what-is-a-healthy-b12-level/

    The holistic M.D. I went to said she liked to keep her patients at 1200, no lower. When she gave me a prescription for a shot a day I didn’t use the prescription for a long time, thinking it must have been an error. But, when I did use it pain from nerve damage I’d been told was permanent, went away.

    What you probably need to be looking at is whether or not you still have symptoms of low vitamin B12.

    Thank you for taking the time to write a comment.
