i naturally want to ensure that i have enough Vit B 12. i have found current wriitngs on the types of *SUBLINGUAL B12 available. below are some of the articles i have read to help me decide.
But first, a review of the book “Could It Be B12? An Epidemic Of Misdiagnosis”
Written for both the patient and the interested layperson, this detailed book outlines how physicians frequently misdiagnose B12 deficiency as Alzheimer’s disease, multiple sclerosis, heart disease, mental retardation, Parkinson’s disease, depression, or other mental illnesses.
*sublingual: Latin for “under the tongue”, refers to the pharmacological route of administration by which drugs diffuse into the blood through tissues under the tongue.
I am a Chiropractor who has been practicing in the out islands of the Bahamas for 10 years, and prior to that I had a 30 year practice in the Hamptons on Long Island, NY. I am also author of the book “Chiropractic The Superior Alternative.” Chiropractic: The Superior Alternative
“Could It Be B12? An Epidemic Of Misdiagnosis” is the most important book I have read in decades. In it the authors, Sally Pacholok R.N. and her physician husband Jeffrey Stuart D.O., clearly, concisely and convincingly call our attention to a condition that exists in epidemic numbers.
The authors shine the light of day on the fact that deficiency of vitamin B12, a vital nutrient, is much more common than most doctors ever realized. They show that the current standard for what constitutes a normal level of vit.B12 on a blood test is in fact woefully inadequate, and a fraction of the amount necessary to support optimal health and prevent a whole array of conditions directly attributable to B12 deficiency. Pacholok is on a mission to call attention to this often unrecognized deficiency and to raise the bar of what constitutes a healthy level of B12 when measured by blood test.
Pacholok gives scientific proof and compelling statistical evidence that B12 deficiency is responsible for, or a contributor to a whole host of neurological conditions, as well a psychiatric disorders. This list includes Alzheimer’s, and senile dementia as well as Multiple Sclerosis and Parkinson’s disease. It also is a possible cause in cases of infant and juvenile failure of normal neuro-musculoskeltal and arrested intellectual development. This book is rich in case histories of real people whose doctors failed to make what should have been an easy diagnosis of B12 deficiency, but instead of running a simple, inexpensive blood test, opted for other expensive tests, often including costly CAT scans. They instead came up with more exotic and dire diagnoses and treatments.
Pacholok shows us that a high percentage of falls and fractures by senior citizens are caused by B12 deficiency. That some of the most commonly prescribed drugs like Nexium and Prilosec as well as oral diabetic medications to name only a few contribute to B12 deficiency. Popular gastric bypass surgeries virtually guarantee that the recipient will develop a B12 deficiency.
This book is a “must read” for all doctors. It is extremely relevant to Chiropractors, like me who see many patients with a variety neck and back pain and neuropathies especially of the lower extremities, and others who consult us for injuries sustained in falls, some of which are possibly caused byB12 deficiency. Chiropractors, need to be acutely aware that it causes spinal cord degeneration, and must entertain the possibility of this deficiency especially in cases that are unresponsive to their care. We must not fall into the trap of writing off neuropathies we see in diabetics as, simply, diabetic neuropathy or old age if the patient is elderly. Doing so, we may miss the window of opportunity to help save a life, or improve the quality of a life. There are many cases of missed diagnosis which, if they had been caught in the early stages, before permanent neurological damage had been done, could have, saved lives or prevented permanent disability.
The bottom line is that Vitamin B12 deficiency is much more common than most of us have realized. That recognizing it, diagnosing it and treating it is easy and inexpensive. Doing so, any doctor willing to open his/her eyes can contribute to saving lives as well as restoring and preserving quality of life for millions of people while saving billions of dollars in health care costs and personal finances. The early recognition of B12 deficiency can help the twilight years be enjoyable and rewarding as opposed to the exercise in endurance it becomes for too many. That constitutes a win/win in my book.
went and bought 6 different brands of methylcobalamin recently so I could see which one I liked best and keep buying that one.
This Solgar product was easily the winner and I’ve bought tons more of it already. I preferred it to Jarrow, Country Life, Source Naturals, Enzymatic Therapy and Bluebonnet – although the Bluebonnet one was the runner up and also very good. The Bluebonnet one tastes the best.
Solgar methyl B12 by far has the smallest tablet size. It’s about twice as large as the 1000 mcg version Solgar does, but still very small and roundish, and fits under the tongue comfortably. All the other tablets are not rounded, or this small and some even have quite sharp edges (especially Jarrow!). It’s even comfortable and easy to do two of these at a time, one on each side under the tongue. You can just put them there and forget about them. Smaller size means taking in less fillers too which is good if you’re having quite a few of these each day. They also last a good half an hour or so which is important if you want to get good absorption through the mouth and not just swallow it all and defeat the purpose of a sublingual.
It’s also gluten free and tastes okay, sort of a bit like those pink musk lollies. I don’t love the taste but it’s mild and much nicer than some. The taste to me is neutral. Solgar and Bluebonnet sublinguals don’t have that very dry texture mid-use which can be irritating in the mouth. They work well too!
It is just not true as some claim that oral B12 products as absorbed as well as sublinguals. They are not, although the best absorption comes of course B12 given IV or injected IM or subcutaneously. There is also liposomal B12.
Everyone needs one of these 5 mg sublinguals daily at least, or as much as is tolerated and feels good. B12 over 1 mg needs to be accompanied by at least 1 mg of activated folate too (avoid all synthetic folate!) plus a good B complex.
If you have any diseases affecting the kidneys or bladder, any neurological disease, mental illness, balance issues, numbness or tingling or shooting or buring pains in your rams or legs or hands or feet it’s a really good idea to get checked out for B12 deficiency. It is a lot more common than you may think and being a meat eater doesn’t guarantee you wont have low levels as these can be caused by gut issues such as low stomach acid and many other things. The wonderful book Could It Be B12?: An Epidemic of Misdiagnoses explains everything you need to know.
Methylcobalamin is a coenzyme form of vitamin B12 and is essential for cell growth and replication. It is more concentrated than other forms of B12 in the cerebral spinal fluid where it can be used by the central nervous system. It donates methyl groups to the myelin sheath that insulates certain nerve fibers. It also plays a role in maintaining a healthy sleep/wake cycle, as well as normal nerve function.
The recommended dosage is often 1 – 5 mg taken sublingually daily – even for healthy people. The dosage used to treat neurological diseases, B12 deficiency and MTHFR/methylation issues etc. is often 5 – 20 mg plus taken sublingually daily, depending on the patient’s response.
I think more companies should copy the shape of this sublingual, and the smaller size. It’s so much nicer and easier to take. Some of the bigger ones can really irritate your mouth and just don’t fit in the mouth comfortably. This is a great product and methyl B12 and B12 generally is just so so important! 5 stars.
As you might imagine, I get into a lot of discussions about vitamin B12 on facebook and twitter, and also via email. Vegans have many good questions about this nutrient. And sometimes some not-so-good opinions about it.
This past year I found myself chatting with the editor of a vegan publication who insisted that my perspective on B12 supplements was outdated. She was convinced that supplements were unnecessary and knew this because of what she had learned on a holistic health cruise.
Okay, well I’ve never been on a holistic health cruise. And I have no doubt that some are better than others. It’s just that, when it comes to vacations, I lean more toward Yellowstone National Park or maybe poking around antique stores along the Maine coast. Whether or not those are the better choices, at least they aren’t sources of dangerous nutrition misinformation. And the idea that vegans don’t need to supplement with vitamin B12 is just that.
I don’t claim to know everything in the world about optimal nutrition for vegans. Nobody does. But based on the available evidence, I do know that—right now—the only responsible advice is for vegans to supplement with this nutrient. Current recommendations are for vegans to supplement with cyanocobalamin in one of the following three ways:
2.5 mcg two times per day
25-100 mcg daily
1,000 mcg two times per week
When I share this information on social media and elsewhere, people often want to know what brand of supplement I take and what brands I suggest. I’m currently taking a Safeway brand of vitamin B12 providing 1,000 mcg. I take it twice per week. It’s cheap and readily available. But when I started to dig around on the internet to find a few other brands to recommend, it turned out to be much more difficult than I expected.
I was looking for supplements that are vegan (which means no animal-derived fillers; the B12 itself is always vegan) and that provided cyanocobalamin. I also wanted one that doesn’t provide other nutrients.
Of the vegan supplements I found, most contained methylcobalamin, not cyano. And a few that contained cyanocobalamin provided a hefty dose of folic acid which may or may not be a problem.
Although there is some evidence that folic acid supplements could raise risk for cancer, the studies on this are conflicting. Still, it makes sense for vegans to err on the side of caution where these supplements are concerned. Our diets can provide plenty of folate (the natural form of the vitamin) and so we shouldn’t need to supplement with it. (The exceptions are pregnant women and women trying to get pregnant; they should take folic acid supplements.)
Many of the cyanocobalamin supplements seemed to be vegan, but it wasn’t always entirely clear that this was so. Almost all included stearate or magnesium stearate, ingredients that may or may not be vegan. Some brands, like mine from Safeway, specify “vegetable magnesium stearate,” but most simply don’t say.
Many readers of this blog are not concerned about these minute filler ingredients in which case any of the supplements below should be fine. But I’m providing the information about these ingredients for those who prefer to know.
With all of that in mind, here is a list of vitamin B12 supplements that provide cyanocobalamin with no additional nutrients.
These three brands appear to be vegan:
These brands contain either stearate or magnesium stearate of undisclosed origin:

1. Priscilla February 6, 2015 at 11:51 am # I use Sundown Naturals sublingual B Complex (liquid drops). The bottle states it is a “vegetarian formula”. It provides 1200 mcg B-12 (as Cyanocobalamin). I buy it on Amazon but I have also seen it in some Food Lion stores. Reply
◦ Ginny Messina February 6, 2015 at 12:21 pm # Okay, I’ll look into this one. It sounds like the one you are taking provides a number of different B vitamins–is that right? But it looks like they have a line that includes several different B12 options. Reply

2. Jim February 6, 2015 at 12:11 pm # What lead you to choose cyanocobalamin vs methylcobalamin? Doesn’t ingesting cyanocobalamin introduce cyanide into your body? Reply
◦ Ginny Messina February 6, 2015 at 12:20 pm # There is evidence that the methyl version may be less stable so that huge doses are required. And it just hasn’t been studied as well as cyanocobalamin. The cyano form does provide some cyanide but it’s a very tiny amount. Reply
▪ Cristina February 9, 2015 at 2:38 pm # I’m curious! Can you provide the peer reviewed study? I have studied bioinorganic chemistry, and from what I understand B12’s purpose is to transfer methyl groups, so buy ingesting the form without the cyanide group, I’d think it’d be more efficient? Reply
▪ Axel Lieber February 9, 2015 at 5:43 pm # Cristina, cyanocobalamin is usually preferred because it’s not susceptible to oxidation. The literature generally states that it is readily converted so really no point in fussing about it. Here is a link for you. I don’t have access to this so I don’t know what it says. If you do have access I would greatly appreciate if you could report back here what it says. http://www.researchgate.net/publication/17624648_Absorption_of_cyanocobalamin_coenzyme_B_12__methylcobalamin_and_hydroxocobalamin_at_different_dose_levels Reply

Apparently the authors found that cyano and methyl B12 have similar absorption in humans at doses of 1 to 25 mcg, and the % absorption drops off as the dose increases. (Note that B12 supplements can be as high as 5000 mcg!) Reply
◦ Angie June 26, 2015 at 4:07 pm # just watched this video by a doctor who has researched B12 ,which totally contradicts your claim about cyanocobalamin, in fact says it is simply the cheapest to manufacture, is very bad for us and should be totally avoided https://www.youtube.com/user/GlobalHealingCenter?v=C4CuwUV0k20 Reply

I emailed the Nature’s Own a while back to be pedantic, they said it’s suitable for vegans. Seems to be in most Australian supermarkets and chemists. I did the Cornell/T Colin Campbell Foundation plant-based nutrition course – a staff member recommended Jarrow methyl supplements (sublingual/chewable) if people were concerned about B12 (pregnancy, long-term vegan, other reason to suspect low levels), otherwise take no supplements (possibly this is what is recommended on “holistic health” cruises as well?). I’ve been taking both supplements recently… Food and yeast is generally fortified with cyano, yes? So I’m taking in that as well… I’m debating whether to ditch the methyl due to higher cost/lesser shelf life… or whether to ditch the cyano and eat more nutritional yeast/fortified snacks… although the tasty methyls are popular with my kids… Will probably just keep doing what I’m doing… assuming that’s not too much… B-12 is water-soluble so it’s ok to get a bit extra, yes?

I think it’s less likely to be a problem with something like B12 than with herbal extracts, but it’s true that it’s hard to know what you’re getting with supplements. One thing you can do is look for those that carry a USP logo on them which shows that they have been verified to contain what they say they contain. Reply

Is it true that you shouldn’t take B12 in tablet form if it’s not chewable or dissolvable?

I picked up a brand from Bellingham Community Co-op which seems to be their own brand. I was a little confused by the options in store, so I’m pleased to see this one meets all your recommendations! This one has 1,000mcg cyanocobalamin, and lists the magnesium stearate as being from vegetable source. In fact it even specifically labels the bottle as being suitable for vegans. I had been curious about the dosing, as the dosage recommendations on the bottle are one a day, which seemed excessive for 1,000mcg. Having read this post my bottle will now last >3 times as long!

I am wondering, is there no concern about cyanide for children at these doses? I can split the 500 mcg tablets into fourths with a pill cutter and just give it to them every day, but that would be 125 mcg, above the recommended daily dose, which is 20-75 for their age group, according to Jack Norris…I don’t think I can split them smaller than that. Would that be better? 700 mcg per week vs. 1500, but more per day than recommended. Just to complicate things, the newly vegan son eats some B12 fortified foods, and the younger, who is not a vegan, eats a hamburger a week, though no other amimal foods (picky eater). Thank you for any insight. Sorry for the novel. Reply

25. Radha Sahar February 7, 2015 at 1:05 pm # Thank you for your wonderful service through this blog, Ginny. I really appreciate your knowledge and generosity to share it. We are vegan, supplement each day, and get a free blood test each 6 months to monitor our B12 levels, which seem to be OK. But a friend, who is on a mainstream, diet including meat (and too much alcohol), is regularly deficient in B12 despite his blood level reading normal!!!(according to his doctor, who prescribes intravenous shots every so often to keep him on track … is that the alcohol?) Rather puzzling! To add to my confusion, naturopaths here in New Zealand claim that methyl is better absorbed by the body. One friend had been taking cyno for years, was suffering from extreme exhaustion and was alarmed to be diagnosed with pernicious anemia. She switched to methyl and has regained a good level. Could it be that people vary as to what type of B12 they absorb? If so, the issue is not so clear. And if blood levels can also be counted on only to some extent, it is extremely confusing! The natural questions to then ask, are (1) what is the safe B12 dosage limit? – (so we can take a bit more, or some of each form, to ‘cover’ us if we are tired etc), and (2) to what extent does B12 need it’s other B vitamin components in order to be well absorbed? And if we need more of the B vit group, what components are most important, and safe to supplement with? I don’t like taking supplements of any kind, and only take B12, an occasional Vegan DHA/EPA, and some Vit D towards the end of winter. I tell all people interested in vegan diet that they must take B12 – and give them a link to your blog of course! Reply
◦ Ginny Messina February 9, 2015 at 12:39 pm # Yes, alcohol can definitely affect B12 levels. I don’t know why your friend would do better with the methylcobalamin than cyano, though. There are all kinds of possibilities, including different dosages or even the quality of the supplements. As for the highest amount to take, there is no good info on that and excess B12 is generally excreted from the body. But I wouldn’t go crazy with it and would try just a little bit above my recommendations if you feel that you need it. Reply
▪ Radha Sahar February 9, 2015 at 1:25 pm # Thank you Ginny. Good advice. I might alternate the methyl (Source Naturals 1 mg daily), with cyno for a change. Your advice on cyno is new to me, and I know this is the standard form prescribed by doctors. It is only naturopaths who are currently recommending methyl. Considering most of them here recommend people eat plenty of raw cows milk, butter, coconut oil, and avoid all soy, as if it were poison, and grains are also ‘bad’ I’ve serious reservations about where they’re coming from. Their ‘methyl’ might be yet another ‘health-fashion trend’. I feel healthy, am monitoring well, and my levels are ‘good’, but I would like to learn more as to why cyno is better, as this is of crucial importance to vegans, as you say! – any links? Thanks again, Radha Reply

32. L C February 9, 2015 at 1:48 pm # I’ve been trying to find a brand that is effective and safe for my 2-year-old daughter. I would prefer not to give her a multi-vitamin chewable, but all the b12 sprays (which are mostly methyl anyway) I can find say “not intended for children” on them. As a nutritionist, Ginny, what is your take? My daughter currently drinks enough fortified soy milk every day to be ingesting about 100% of the adult intake recommendation, but I am hoping to decrease her intake of that soon (it’s got more added sugar than I’d like). The two nutrients it provides that I can’t seem to find good replacements for are b12 and iodine. She already takes a chewable D supplement, and other than that her diet should be giving her what she needs. Your advice would be so much appreciated! Reply

I would be most obliged if you could post links to the science. Reply

The methyl product I have open is stored in a dark medicine cabinet and the bottle’s glass is quite dark, so it’s *probably* protected from light, though I’m considering moving it to my refrigerator to further slow degradation. What’s funny is that the methyl form is about all that’s available now at my local health food store, yet at Fresh & Easy near me, which is conveniently open 24 hours, they have a vegan cyano product, so it’s actually much easier for me to get the more stable form, as well ! :) Reply

55. Michelle February 10, 2015 at 8:08 am # Hi Ginny! Thanks for the article. I have noticed that most (?all) of the B12 supplements on the market are sublingual. Why is that? I know people with true pernicious anemia, who don’t make intrinsic factor in the stomach, cannot absorb B12 through the GI tract and therefore need B12 either in an injectable or sublingual form. But for those of us without pernicious anemia, is there any difference between sublingual and a regular oral tablet? Or are the manufacturers just making the sublingual to capture the pernicious anemia market? thanks! Reply
◦ Ginny Messina February 11, 2015 at 10:48 am # I think they are probably marketing this as better because it is absorbed directly without digestion. And as you noted, it could be for some people.

I am studying the advanced micro-nutrient metabolism materials right now. I don’t understand why there isn’t a B-complex vitamin out there for vegans that has only the B-vitamins we need and in the amounts we need them. We can measure percent content in foods and percent absorption; there is no reason we can’t formulate a complex that actually supplements our nutrition needs instead of overdosing on vitamins that vegans are adequate in. I think we should find a venture capitalist to make one for us. I don’t think it would be hard to find someone in this budding health conscious environment. – Sarah Reply

So everyone should take methyfolate and methylcobalamin supplements. What do you think about this?

I have been a vegan (fully) for 10 years now and b12 deficiency has been a curse and i do not wish to enroll doctors because of the closed way they approach things, twice now i have had to have injections of B12 which will be made from something synthetic, any way just i recently i have put myself thru hell seeing if my body would fix my extreme tiredness by doing that which it needs to do, it would not so i finally secombed and now i have to have a truckload of the stuff to remove the tiredness problem. As you may know that b12 is not available in the natural or unnatural world, of food, there are only 2 places that we can get b12 and that is from dirt, and inside our gut. B12 is a waste product of a bacteria. I am very stubborn when it comes to the ‘system ‘ telling me things and i am very suspect of everything coming at me, i knew in my heart of hearts that there will be a way to find b12 in the natural, it was right under my nose all the time and i have used this source before for healthy living but not for b12 at the time, now is different so i searched and searched and this is what i found. HEMP milk, has in one glass 25 percent of our daily intake of b12, it also has 10 amino acids amongst other things. Check it out you will be amazed. happy vegan to you Gary Reply

76. Margaret January 6, 2016 at 9:03 am # I am quite surprised you are recommending cyanocobalamin. It is not as bioavailable as methylcobalamin and so the body needs to convert the cyanocobalamin to the methylcobalamin. in addition, doesn’t the body then need to excrete the remnants of the cyanide after it’s been metabolized? Also no discussion of tablet vs liquid form. Cyanocobalamin may be stable but liquid will always be absorbed more efficiently than tablets. I use Vegan Safe Bioactive B12, which is a blend of methylcobalamin and adenosylcobalamin. it is made by Global Healing Center. I used to use cyanocobalamin to treat my B12 deficiency after being vegetarian for a long time, but after about a year, my hair started falling out. I no longer have this problem. Reply

▪ KJ January 6, 2016 at 11:00 am # Your explanation for why cyano is better than methyl is really not impressive. You prefer cyano because there is more research done on it? I have been taking the methyl form for several years (prior to that have regularly used Red Star nutritional yeast, and I am a 45-year vegan. No signs or symptoms of B12 deficiency. Everything I have read leads me to believe the methyl form is superior. Reply
▪ Ginny Messina January 6, 2016 at 1:10 pm # Yes, the fact that there is more research on it allows us to make appropriate recommendations to protect vegans against deficiency. Because of the lack of research on methylcobalamin, and the fact that we know it isn’t as stable or reliable, it’s difficult to know how much people actually need to prevent deficiency. Therefore, it is risky to depend on the methyl form of this vitamin supplement. That’s why vegan nutrition experts who have looked at the actual research recommend cyanocobalamin. I’m not surprised, though, that everything you’ve read says otherwise. There is tons of misinformation about this on the internet. And since it can take several years to develop a deficiency of B12, people may not realize that they are not supplementing appropriately. Reply
