Vitamin B12 and ME/CFS

 Last week, I wrote a post about methylation and its importance to people who have ME/CFS (and other immune disorders as well). If you haven’t read that post yet, I highly recommend you go back and read that one first because these two topics are inextricably intertwined. If you want even more detail than what I am providing here, ProHealth has an excellent article on B12 and Methylation that includes 225 scientific references!


So, with that basic knowledge of methylation, we already know that vitamin B12 is absolutely essential. It feeds a critical step in the methylation process, and without it, the whole process breaks down. That’s only the tip of the iceberg for B12 and ME/CFS, though.



Why is B12 so important to ME/CFS patients and what does it do?

We know that B12 is a critical component of the methylation cycle, which regulates detoxification, as well as critical processes in adrenal function, immune function, and the nervous system. Here are other facts about vitamin B12 and ME/CFS:

  • Many people with ME/CFS and FM are actually deficient in B12

    • Many people in the general population are deficient, including 78% of seniors in one study.
    • People with ME/CFS often have low stomach acid and high bacterial growth in small intestine – both of which lead to B12 deficiency.
    • Blood tests for B12 miss deficiencies 50% of the time (so if your blood tests show you have adequate B12 that is not necessarily true).
    • B12 deficiency can cause IBS (Irritable Bowel Syndrome) symptoms that are very common in ME/CFS; IBS can lead to a B12 deficiency since nutrients are poorly absorbed – this is another of those vicious cycles present in ME/CFS.
  • B12 helps regulate Natural Killer cells, a critical component of the immune system.

  • In multiple studies, people with ME/CFS have been shown to have elevated levels of homocysteine, which can lead to cardiac problems; B12 helps to convert homocysteine to methionine.

  • People with ME/CFS have been shown to have excess amounts of nitric acid (NO) and peroxynitrite (-ONOO), a potent oxidant. Both of these lead to problems in multiple body systems that get progressively worse, as the high levels of NO and –ONOO in turn produce more of these compounds. NO also disrupts the methylation cycle. One form of B12, hydroxycobalamin, is a potent NO scavenger that can break this harmful cycle.



This was all news to me! Many years ago, when I first heard of doctors giving ME/CFS patients B12 shots, I thought it was an insignificant treatment, something done when doctors didn’t know what else to do because there was a myth that B12 improved energy. Wow, was I wrong!


What is Vitamin B12?
B12 consists of 4 different but related –cobalamin molecules (so named because they contain cobalt):

  • Hydroxycobalamin –
    • Scavenges excess NO
    • Especially critical for neurological disorders and people with high levels of cyanide (smokers and those with certain metabolic defects)
  • Methylcobalamin –
    • Considered by many experts to be the most active form of B12
    • Used directly in the methylation cycle
    • Protects neurons against glutamate toxicity
    • Promotes nerve cell regeneration
    • Only form of B12 that helps in regulating circadian rhythms (sleep/wake cycle)
    • Because it is directly used in the methylation cycle, it helps support production of serotonin, dopamine, and melatonin, which are directly responsible for good quality sleep.
  • Adenosylcobalamin (dibencozide) –
    • Another highly active form of B12
    • Essential for energy metabolism
    • Required for certain neurological processes
  • Cyanocobalamin –
    • Synthetic form of B12 not found in nature
    • The most common form found in nutritional supplements
    • Must be converted in the liver to other forms
    • Lowest activity level of all forms of B12
    • It is, however, essential in working together with hydroxycobalamin to quench NO

Dosing/Recommendations


The U.S. Institute of Medicine recommends that all adults over 50 use B12 supplements, so given everything listed above, it seems that every ME/CFS patient could benefit from B12 supplementation. What are the best ways to get it?

  • Meat, eggs, fish, and shellfish contain the highest amounts of B12 in food but only about 50% of it is absorbed by the body (in a healthy GI tract) – IBS and other common GI symptoms in ME/CFS hamper absorption even further. Vegetarian sources of B12, like algae, are not bioavailable. So, supplementation is necessary.
  • Most top ME/CFS doctors (Lapp, Cheney, Levine, DeMeirleir, others) routinely use B12 for their patients
  • A study conducted by Dr. Charles Lapp (a renowned ME/CFS expert) found improved energy levels with B12 supplementation of 2500 – 5000 mcg every 2-3 days, even in ME/CFS patients who did not test deficient in B12.
  • Though injections have long been the gold standard, there are some newer studies showing oral and sublingual (under the tongue) types of B12 supplements to be as effective as injections.
  • Most direct benefits come from the hydroxycobalamin and methylcobalamin forms of B12, but the other two forms support and help these to work better, so all 4 forms can be helpful in ME/CFS.
  • Studies show it can take 3 – 6 weeks or more to fully see the benefits of B12 supplementation.

 From what I have heard and seen myself, many doctors still feel that injections are the best way to get B12 into the body where it can be used effectively; others use sublingual or oral B12.



Our Experiences


My son has been getting weekly hydroxycobalamin injections (1000 mcg) for several years now. We did not see an immediate effect, probably because his methylation process was so severely dysfunctional, and his system was overwhelmed by his three tick-borne infections when he started. Slowly, over time, as we addressed his methylation issues (see methylation post) and treated his infections, we saw that the B12 was having a positive effect. He feels a lot better, and we know the B12 is part of the reason why.  He also uses Black Bear Spray (a mouth spray form of B12) several times a day and finds that using it before or during a class, homework session, or a test helps to improve his mental energy and cognitive function.



He recently increased to 2 injections a week, and wow! He felt a huge burst of energy and improved cognitive function with that second weekly B12 shot. The effect was so positive that he now drives home from college twice a week to get a shot. Our next step – recently decided with the biochemist/dietician we consult with – is to switch him to daily shots that come pre-loaded so that he can do them himself at school, with hydroxycobalamin every day and methylcobalamin every third day.



As for me, last summer, I started using a product called B12 Extreme from ProHealth. I bought the product after reading that article they featured on B12 and ME/CFS because it is one of the few B12 products that contain all four types of B12. They are sublingual tablets, and, at first, I felt a mild improvement in energy when I took one each morning. I still take them every day, though I don’t notice that same burst of energy anymore, and blood tests done in December showed that I still had fairly low levels of B12. The biochemist/dietician we work with is reviewing my genetic test results to see if I have any problems metabolizing various forms of B12 and will make her recommendations based on that. I suspect injections may be in my future, too.



In summary, B12 seems to be essential to many body processes, and B12 supplementation should benefit anyone with ME/CFS. Just remember, though, that B12 is just one piece of a very complicated puzzle. If, like my son at first, you don’t see any benefits after a month or two of B12 supplementation, then you probably need to address other pieces of that puzzle, like other parts of the methylation cycle or treating underlying infections (if none of the typical ME/CFS treatments seem to work for you, then you almost certainly have underlying infections that need to be diagnosed and treated before you can move forward).


I will keep you up-to-date on my own B12 experiences, and I would love to hear about yours as well. Has B12 helped you? At what doses and in what forms? This seems to be a simple, inexpensive treatment that can help anyone with ME/CFS.

ADDENDUM 8/25/15: Our dietician recently advised us that people with ME/CFS should NOT take cyanocobalamin. The cyano- means it contains cyanide which must be detoxed before you can use the B12. The detox pathway is part of the methylation process and uses up LOTS of glutathione which is already in short supply for us - so it does more harm than good. This is especially important to know because it is very common in typical B12 supplements and is the only ingredient in a new B12 pill marketed under the brand nae Eligen. Best to avoid cyanocobalamin and stick to one of the other 3 types.

  1. That is a very interesting topic, my brother suffers by anemia, by the time I started to read about it, I realized there are so many types. The root of these disease is the lack of a proper alimentation. Unfortunately not everybody on this planet cand afford a good life. Before this article I was readig this one, maybe will help http://dailypeople.org/lack-of-vitamin-b12-causes-anemia-pernicious-anemia/

    Hi Sue:

    I use Methylcobalamin injections 2 to 3x times a week plus I use Glutathione injections twice a week. When I don't use the medicine, I feel a big difference. It really helps me - can't go to work on it but gives me enough to get out of bed for awhile and get things I need to get down while pacing.

  4. The post is very informative. I was diagnosed with a severe case of vitamin b12 deficiency a few months ago. Thus my doctor advised me to take Vitamin b 12 sublingual once in a day. I can feel the difference in my body after having this.

  5. I get the worst headaches when I take B12, OR folate, I tried caties whole food B, and Country Life and both did this, wish I knew what I could take but right now nothing.

    Hi Sue, I am wondering whether the black bear energy spray might help my son. He is using a locally-produced sticker which is supposed to supply about 1000mg of Vit B12 (methylcobalamin) through the skin 2-3 times per week, but perhaps the spray would be a useful addition. Sadly, it has to be ordered and imported to South Africa - quite pricey. Could you give me an idea of how much of the spray your son uses? A bottle per week, or less? Thanks, Elizabeth

    1. Hi, Elizabeth -

      I don't know how much Jamie uses because he's away at school. I think he often forgets about the spray, especially now that he takes B12 shots every other day (which has helped tremendously). However, it lasts for MUCH longer than a week! If you zoom in on the label on amazon or anywhere else it is sold, you can read how many "sprays" per bottle. Like I said, Jamie isn't using it much, so I've only bought 2 bottles in the past year or so. I try to remind him to use it before exams and other times he needs an extra boost.

      There's also a link in this post to B12 Extreme which is the product I use - very high doses of all 4 types of B12 in a sublingual tablet. It's also expensive, from ProHealth, but it has helped me. Nothing beats injections for effectiveness, though, especially if you do the genetic testing and can confer with someone regarding which types are best for your son (I'll be glad to give you the contact info for our dietician/biochemist who helps us - she is actually from S. Sfrica though she lives in the US now and meets with her patients via Skype - just message me).

      Hope that helps -

  8. I saw my doctor today and he is referring me to a specialist as a possible CFS sufferer. I already have a B12 injection once every 10 weeks because I had a gastrectomy and so can't absorb B12 and I feel the benefit of the injection for a few weeks mid cycle, My question is...is it normal to feel the benefit of B12 for such a short time or would I need more injections and if so how many could I safely have? Thank you for any advice you could offer.

    1. Carolyn - Everyone is different but I can speak to our own experiences.

      My son gives himself B12 injections every other day, alternating between hydroxy- and methyl- types. He started with weekly injections, but the effect wore off after a few days, so our dietician/biochemist suggested smaller doses at shorter intervals to keep him feeling good longer. Once every 10 weeks isn't much at all!!

      As for safety, you really can't overdose on B12 - it's a water soluble vitamin so you just pee out any excess.

      Good luck - I hope the specialist helps you!

  9. Not sure if this helps or if anyone is interested but I recently heard about a new oral prescription alternative to the injections called Eligen B12. I recently read that it works even if you don't have intrinsic factor (so even if you don't have normal gut absorption, which would mean no more shots. Apparently it came out a month or two ago. Has anyone tried it??

    1. Thanks so much, Chloe! Coincidentally, a friend JUST asked me about Eligen this week and I hadn;t heard of it. Any idea why it is more effective? In the past, oral B12 was thought to be poorly absorbed. Anyway, thanks so much for the heads up - I will ask our dietician about it this week :)

    2. Anytime, Sue! Happy to share my findings :). From what I've read and heard Eligen B12 has a unique carrier technology, which is what allows the B12 to be chaperoned through the GI lining even in patients who cannot absorb B12 intestinally (and who lack intrinsic factor). So it works independent of those issues and can be used as an alternative to injections because it will drop the B12 directly into the bloodstream within 30 minutes just like the IM injection. The website has a lot of information on it (EligenB12.com), but I'd be very interested to hear what your dietician has to say about it as well!

    4. Hi, Chloe -

      I asked my dietician about the new Eligen B12 product - very interesting discussion!

      She hadn't heard of it but looked it up. Although the new method of delivery is interesting, this is not a product that is good for those of us with ME/CFS because the type of B12 in Eligen is cyanocobalamin. The cyano- stands for cyanide, and she said in order for the body to process the cyano-type of B12, it has to first detox it. Since detox involves the methylation process which is already dysfunctional in us, this means that the cyano-B12 is putting a lot of extra stress on our methylation process - not something we need. We are better off sticking with the other 3 types of B12, depending on our genetics and what we need from it.

      So, an interesting breakthrough but not effective for us - perhaps they will apply this new delivery system to other forms of B12 down the line.

      Thanks so much for telling me about it!

    5. Hi Sue,

      Ohh, I see. Very interesting. Yes, perhaps there will be other versions with other forms of B12 eventually! Thanks for getting back to me and looking into it!!

  10. Hi does anybody know where I can get the methyl B12 injection for my 6year old autistic child? I read and studied online that it's very very effective and widely used for ADHD and autistic kids in the USA. I'm so done with other traditional medications given to her their side effects are horrible and don't want to risk my child,s life again on the long run. I need help ASAP please. I'm based in joburg, thanks

  11. Hi -

    I don't know about SA but here in the US, injectible B12 requires a doctor's prescription and then you get it from a compounding pharmacy. Ask your doctor about it.

    Autism research has shown many links with ME/CFS, including the methylation problems - the two conditions may even be two different expressions of the same type of immune dysfunction and genetic predisposition. Family studies show multiple cases of ME/CFS and autism in families.

    Another thing for you to look into is low-dose naltrexone. My son and I have had good success with it for ME/CFS, but there was a lot of research done on using it for kids with autism. Some of the studies are cited here:

  12. Thanks a lot Sue and sorry for the late reply. I was able to get the methyl b12 patch and the mouth spray will give both a trial and see.
    I will also have a look @ the links you posted. God bless you.
