  • What Your Doctor Doesn't Know About #B12 Could Save You From #Burnout, #Fatigue & #Anxiety
    😳
    B12 insufficiency is a situation that I see every single day in my practice working with busy, high-functioning professionals.
    🏃
    Key learnings in this video:
    1. The Canadian "normal" range is stupid
    2. Doctors are not trained to identify early signs of insufficiency
    3. Plant-based, vegan & vegetarian diets are deficient in B12
    I updated this video to include more clarity around ranges and units:

    Sixty-five year old, UK.
    My B12 came back at 132 pg/mL, I'm also vitamin D deficient and anaemic. I was only tested in the first place after a chance conversation with a B12 deficient colleague 10 minutes before my appointment with my cardiology consultant. I'm hypothyroid, take a PPI and have been on HRT for 26 years. Consultant wasn't concerned about my B12 levels and placed more emphasis on getting my vitamin D sorted, his words were "her B12 is 132, which is neither here nor there" - gee, thanks Doc.
    This didn't happen overnight but as it has a lot of symptoms in common with hypothyroidism, I've always put it down to that. I've been feeling progressively worse and worse over the last couple of years and when I'm not at work, I'm asleep...or wishing I was asleep.

    • @drjmarr
      @drjmarr  Před 8 měsíci +6

      Sorry to hear you've been through a tough time. There's a lot going on here and only rectifying B12 insufficiency won't make everything better, but it's got to be part of the picture. PPIs and hypothyroidism both negatively impact the absorption of B12. Consider speaking with your consultant to consider B12 injections while you optimize thyroid function, and ideally wean off the PPI if possible - It's working against you to digest proteins, absorb B12 and iron, contributing to anemia, likely. However - a PPI is warranted if/when there is concern about chronically damaging your esophagus, so don't make changes here unless you're working with someone who has experience in managing this constellation of issues. Wishing you the best!

    I live in Virginia, USA. Our doctors don’t care they strictly go by the labs. They also don’t tell you that most b vitamins you by her have cyanide in them either way , our lives are controlled by them in many ways. I had to do my own research . I was deficient in several vitamins. According to the labs I had . I was in the low functioning range. I took those vitamins that were low and built myself up. Feel a lot better. I cry every time I go to the doctor. No one listens . They don’t look at past history or family history. They only treat symptoms. Population control. For real!!

      ​@@drjmarr, all areas of developed nations experience the same type of scenario. I practice functional medicine here in Canada, and when I see bloodwork, I'm shocked not only by the notably too-low standard reference ranges but also by the symptoms experienced by individuals whose levels fall within these low ranges but outside of optimal levels. They are hardly ever diagnosed by conventional medicine in specific blood markers, especially in B12 and vitamin D.

      Thanks for the support!! With those digestive issues I'd be curious about measuring MMA even with a solid B12 serum level, but there are likely other complicating factors. SIBO and poor digestive function mean that you'll likely not be processing and absorbing all sorts of minerals and vitamins, but also basic fuels. I'd focus on optimizing digestion first and foremost!

    Hi Dr. Marr. I was googling B12 and your video came up so I watched it. 🙏🏼 thank you! I wish I was out in BC bc I would def make the effort to visit your office! I’m in ON and sadly my Dr. is useless! I went yesterday and pretty much had to beg him to send me for blood work! I just looked at the Blood Requisition and there isn’t a box for B12 let alone any Mineral (eg. Fe) or Chemical Element. Where did those elements go? There used to be the whole left side full of them but not anymore! I’m going to look into the tests on here that I’m not sure what they stand for (but the others I do bc I’ve done enough research!) 🤓🤓🤓 plus I have a background in Chemistry and studied one semester of hematology.
    I’ve been doing some research and thought I might need a B supplement. Anyways great video and informative. I’ll subscribe so I can learn more. Take care!I know how busy you must be so just wanted to say thank you for answering my question Dr. Marr!!! 👏💞

Also, keep in mind, especially for minerals and vitamins - what's in the blood isn't necessarily what's in your tissues. Serum testing for minerals and vitamins isn't tht simple.

      Part of the issue is that doctors - general practitioners or family doctors, at least, are trained to recognize what is normal and what is not - And how to appropriate treat or refer. That is the conventional medical system. It took me over a decade in practice to train myself to let go of "normal" and start asking patients what it was that they wanted to achieve, rather than solely what symptoms they wanted to be gone!

    Even before I became vegan, I had B12 injections as routine - working in a rushed restuarant environment, where you were on your feet all day, and at the end of the night you would realise you hadn't had anything to eat or drink.
    Niacin is another B vitamin that can do with supplementation.
    The other supplements vegans and those on a plant based diet should look out for are Vit D and K2, which are actually not found at very high levels, even in animal products.

      That is definitely too low. Minimum should be 650 so yours is very low. You are probably undiagnosed coeliac. Stop eating all gluten, and retest in a month or two. If it's not up, take an oral supplement of methycobablamine. Test again in two months. If still not up in the normal range (650 - 1000) then you will need the injectable form of methylcobalamin. It's super safe. No chance of overdosing. Safe, easy, wise. Good luck.

    B12 is stored in the liver, and I'm told it can take years to get nerve damage from insufficient intake.
    This makes me belive the blood level won't drop much while the liver has some B12 left.
    I haven't seen that guess confirmed by research, though.
    Does anyone know if that's so?
    If so, measuring blood levels wouldn't be any good indicator of sufficient intake.
    And perhaps also be why the normal range seems so unreasonably wide!
    But this is just me mostly guessing, so I would like to get some facts about that.

      My other videos on B12 are much more clear about units. As an oral supplement, 100ug (micrograms/mcg) is actually pretty low. Lots of multivitamins have 500-1000mcg per daily dosage. Speak to your healthcare practitioner before you start any supplements, but 100ug is pretty low dosage if you're trying to replete a low blood B12 level.

But correlation does not necessarily equal causation. If I hypothesized that lung cancer and other bone or marrow based cancers dumped B12 into the blood, and so cancer causes high B12, then I could conclude that the results supported my hypothesis too.

I was a bit concerned about b12 results since the range in my country is 197 - 771 pg/ml. But you video suggests my levels might be actually good. What would you say? Thank you!

      @K B no it's not, 973 pg/ml is 718 pmol/l when it comes to b12. If you are googling it, make sure you google "b12 pg/ml to pmol/l".

      For Optimal Health, you must raise your Vitamin B12 Levels up to 590 pmol/L which is equal to 800 pg/mL. You can go up to 650 pmol/L according to LifeLabs in Canada. No more than that. Pay close attention to the Units.... This is very important. You can convert the Units from pmol/L to pg/mL. For example 650 pmol/L is equal to approximately 882 pg/mL.

    Hi doctor my “regular” b 12 is 913/946 pg/mL! But I am learning that the accurate blood test I should do is MMA to see an accurate b12 in my cells. So whatever blood test I got for my b12 is not accurate. Why doctors don’t say that ?! My question is if my regular blood test for b12 is pretty high is it mean that my MMA also can be high?? Thank you

    • @drjmarr
      @drjmarr  Před 5 měsíci

      Most doctors don't know that. That's why I have to make these videos! 🙄. MMA results are inversely correlated with B12 sufficiency. So if you have enough B12, your MMA will be lower - if you have elevated MMA, it means you're functional deficient in B12. This updated video talks more about MMA: Symptoms of Vitamin B12 Deficiency - "Normal" levels aren't good enough!?

      That high level of B12 certainly needs investigating. It usually is considered to indicate break down of internal tissues, for some reason. As one's own tissues or organs break down, they release the B12 they have in them. This goes into the blood and can be picked up on a blood test. Definitely speak to your physician about this and get it retested. Good luck.

    • @drjmarr
      @drjmarr  Před rokem +2

      It should be looked into. Often people are getting B12 in something they don't realize, but, if that's not the case, very high B12 can be an effect of some not-so-good stuff so best to get some follow up done.

    My B12 serum value was low normal and active B12 was pretty high. Is that a normal outcome? I was supplementing mega dose of B12 until 2 weeks before bloodtest was done as suggested to not influence the test results too much. I of course continued taking it again right after the needle left my body because it makes me feel better to take it. But this HoloTC test had >150 pmol where anything below 40 is defeciency. Could this indicate my body has trouble using the active B12? All cell bloodvalues were normal.

    • @drjmarr
      @drjmarr  Před 8 měsíci

      By "active B12" I assume you mean holotranscobalmin. It's better than serum B12 as it is the next step in conversion before entry into cells, but still does not represent intracellular B12 status. I still suggest testing MMA. And yes, high holoTC is likely due to supplementation close in time to testing; not really a valid result that we can conclude anything from. The fact that your serum B12 was reasonably low despite supplementation is suggestive of an insufficiency though.

Sadly I have to go abroad for bloodtesting and results came too late to use the blood already send in or take new bloodsample, in my country they only take serum test and dont do HoloTC at all and bloodtesting is very restricted so I go abroad every now and then just to take all bloodtests I am interested in. With the cell testing I meant all tests done on (red) bloodcells were normal, nothing suggestive for B12 deficiency there, but I clearly feel effect when I take megadoses of B12.

Whether the lower B12 levels are due to the digestive issues, or vice versa, you're likely going to feel better with supplemental B12 or intramuscular injections. If you watch my follow up video on B12 it also talks about another test (MMA) which would be relevant here. Find someone to work with who has experience to see if supplementation or IM injections might be reasonable to try.

      @afifahhamilton8843 Před rokem +4

      Coeliac disease is the main cause of low B12, so it doesn't surprise me that your level of 240 is indeed low. In my assessment the normal range should be 650 - 1000, so yours is definitely too low. Ask your GP for two blood tests, one for antibodies to Intrinsic Factor and one for antibodies to Parietal Cells. If either of these is positive (i.e you have antibodies to one or other or both of these) you have Pernicious Anaemia. I assume you are already off all cereal grains, but if not, get off them all, that includes oats. All oats, without exception, contain gluten, even if marketed under the 'gluten free' section. Gluten causes major problems in the gut, as well as other tissues, so nutrients cannot be absorbed, AND they can trigger antibodies to the stomach cell type I mentioned above (parietal cells) and these produce Intrinsic Factor, without which you cannot transport B12 further into the gut where I can be absorbed. Antibodies to Intrinsic Factor mean it is destroyed as soon as it is produced, hence, low B12.
      Good luck.

    My B12 level is a hair over the minimum range, yet my PCP didn't suggest I take supplements.
    So I decided to do it, on my own. It's water soluble, like vitamin C...so it's hard to take too much..
    By the way, I am looking for a new PCP.

    If someone is deficient in B12, does that mean they could also be deficient in other B vitamins? Why the "hype" on B12 specifically it seems?

    • @drjmarr
      @drjmarr  Před 4 měsíci +2

      Good question. B12 is a bigger issue for more people than other B-vitmamins because its mechanism for absorption is dependent on intrinsic factor, for which production is negatively impacted by digestive function. B12 is also more of an issue now as people trend toward more of a plant-based diet, which tend to be deficient in this particular vitamin. On top of that we have learned in the last few years that B12 absorption and metabolism are affected by SNPs in genes like FUT2 and TCN2, and people's independent and unique needs vary with SNPSs in methylation genes like MTHFR associated with homocysteine metabolism.

    • @drjmarr
      @drjmarr  Před 4 měsíci +2

      In supplement form, B-vitamins should generally be taken as a complex (ie all together), but usually B12 insufficiency is an independent issue from other B-vitamins.

      The only reason a B12 intramuscular injection should hurt is if the person administering it is either being mean, or they're poorly trained. I get told by other docs and nurses that I give a "great IM injection", and I always think to myself "wtf are other people doing!?".. B12 injections should be close to painless. Sometimes a very mild ache as the fluid is injected if it's cold coming out of the fridge. This is assuming it's cyanocobalamin or methylcobalamin. Hydroxocobalamin can sting though.

      @drjmarr Hi Dr.J, Thanks for asking. I take regular multivitamins most days - B12 in the current one I'm taking is 8.6µg. Also, my diet would be quite high in animal products, and I would regularly consume red wine (few glasses a week). From my research I understand that all this could have an impact? Would substituting some animal products with plant based and cutting down on red wine bring it down? And of course, I need to stop supplementing for now.

Your multivitamin B12 dosage is really low, but if you've been taking it regularly and for a long time, it's definitely feasible that it's elevated your blood levels on your test.

      If you truly have pernicious anaemia, this is an autoimmune condition - injections should still help, and may be required ongoing. But most doctors erroneously use the term "pernicious anaemia" with B12 deficiency (or insufficiency).
