Hi can you please my message I just sent on this thread. I’m a brand new subscriber and you have the best information but my levels of B-12 are 3825 (I’m scared I’m going to die) and Ferritin is 367. Both dropped about 10% since 8/23/24 to 10/4/24. My WBC and RBC perfect. Basically my entire CBC is all normal. I’ve been researching for a week and am getting limited help other than you. I’m pounding water, stopping all alcohol 0 withdrawals but I was moderating drinking, my BMI is 22%, I weigh 130 pounds. I as of today getting results will discontinue ALL fast food and sodium. Please help me, I have 3 kids and don’t want to die of liver cancer or kidney disease. I’m so sad 😞. If you have time read my post on this thread it tells you vitamins I just started and completely STOPPED as of a few days ago.

Got last year b12 test and levels were 1180pg/ml Didnt realise at that time that i should be concerned as i wansrn supplementing. Retested a month ago it was 1267pg/ml and a week ago 1180pg /ml Also found out that in 2020 it was 1000. All Cbc liver tests normal. Serum electroforesis normal. Peripheral blood smear normal. No symptoms. Liver kidney splen ULTRASOUND NORMAL. BUT i am still worried although my diet is super high in greek yoghurt and high protein diet in general.

Thanks doctor. I keep watching your videos to learn more about B12.

[@johnline]

thanks for this video, you're about the only youtube dr covering it. i wonder if many of the people here were symptom free then had ibs/sibo that led them to high b12 and paradoxical deficiency symptoms. my story is 2018 food poisoning, 2019 sibo onset, candida, dybiosis, and one finding of giardia, and then an onset of crepitus, then knee pain, tmj, knee atrophy, tendonitis, ankle pain, then pain and atrophy spreading to all limbs and hands. have a great deal of muscle wasting in distals, and now pins and burning sensations are setting in, after all other testing the one remainder is neuro. i'm still dealing with ch4 sibo, lipopolysacharides likely leeching into the blood for a long time, and other barcterial gases i've read can be neurotoxic. i've had serum b12 creeping up to 1500pgml last count, and bilirubin has also climbed 5 points over ref. it's hard to tell if my issue is overproduction of b12 at the illeum or mitochondrial shut down from the endotoxic stressors, the carriers inbetween or a wild mixture. other bloodwork is normal, homocystein came back within range on standard lab tests, i await mma via organic acid tests. in the meantime i battle to reverse sibo, because it all started 2 years ago.

[@swintegrative]

Hi Johnline, thanks for the comment. Bacterial overgrowth or SIBO can increase serum B12 levels and yes it can be a struggle to get SIBO in check. I do have a few videos on SIBO you may find helpful. Good luck!

@johnline I’m wondering if any doctor ever resolved or explained any correlation between elevated high B-12 levels and neurological symptoms. (tingling/pins and needles sensations).

another great video! if i have high b12 and folate, but normal iron / ferritin and normal RBC (maybe even slightly high) - would you think this is more of an issue of b12 getting inside the cells? i have a slow metabolism so i suspect my body cant process it quick enough, therefore building up in the blood but why is the metabolic function slow, cell membranes?

since there are a lot of important details here you might consider joining the membership kzbin.info/door/yYt8bEdpNzXK8LyCNh6rugjoin It sounds like you have a high ferritin (you are spelling it different but I think it is the same) and you are taking iron. this is very inflammatory vitamin. Sometimes people need to take this and hard to know all the missing piece to your case but with extremely high ferritin it is certainly effecting your immune cells. Hope that helps. you might check out my other videos on high b12 and ferritin for more context.

Hey doctor ! I have a question for you and I hope you see this… I have been having neurological symptoms since 2018 with no explanation.. I’ve seen a neurologist, hematologist, rheumatologist, etc and all of my testing is normal EXCEPT my b-12 is very elevated… and my bilirubin is elevated as well.. not all the time but sometimes it is elevated along with the b-12. I’ve had liver scans, liver functioning panels and have been told it’s Gilbert’s syndrome and nothing is wrong. Great… the only issue is that my neurological symtoms which are pins and needles in my feet, burning feet and hand, numbness and tingling in the right side of my face, oral sores, etc has not gone away. I am negative for any autoimmune disease at this time.. and my b-12 levels are usually about 1200-1500… I have a mma test done and a Homocysteine test done which was normal, but my b-22 binding capacity test was very very low, so low that it was marked as unreadable… less than the reference range. What do I do??? My family doctor said it could be Transcobalin deficiency causing a functional b-12 deficiency but I don’t know. My hematologist is stumped and said to self inject B-12 and see if my symtoms subside. With mma and homocysteine being normal I am confused why my b-12 binding would be so low. Please comment back if you can. Thank you so much.

[@swintegrative]

Your symptoms are likely not from B12 deficiency with these results. There are other ting that can cause neuro sx. However , it would not hurt to try the B12. Also your might consider a urinary MMA as it is more accurate. You need MS/LC for MMA urine test.

[@nag5253]

Hi Skylar, I know someone with suspected GS ( not tested yet) and his b12 is above range. He has been advised to take molybdenum, b2, thiamine and selenium with iodine ( test those levels before you do) to bring it down. I believe it’s based on the b12 protocol as cofactors are required for b12 assimilation.

Hi! Thank you for caring enough about strangers, to post videos like this! Turns out I have elavated B12 (976) along with elavated S-CRP (11.7) and B-Leukocytes (9.0). I found out after going to the Dr, due to tingling and numbness in my legs. I feared it was MS, because my immune system is bonkers already (alopecia). Symptoms started in a right big toe and then went overnight into all right leg, then left - but lesser degree. Itching, tingling, numbness. I don't have the other typical MS symptoms. Now I'm hoping this is caused by something as silly as having overdosed on B vitamin (took supplements + was following the Keto diet with lots of beef and fish...!) I also have tendonitis in my hand, as of a few months... Trying to sort myself out and I'm in between UK and Swedish healthcare right now... Neurologists have 4-6 months queue to see them - private ones are not taking new patients. The GP said he couldn't help. I should go to the A&E or wait (6 months!) for the neurologist. I pasted the test results from the Dr I saw earlier if you have a sec (it's in Swedish but the words are very similar to English). I just hope my strange symptoms are something relatively harmless - not MS... I would be so grateful for some advice about what I should do with this!

[@swintegrative]

B12 does not cause these symptoms or cause elevated CRP. Whatever is causing the elevated crp (not easy to say what that is) is the likely cause of your symptoms.

[@Hanna-yn5ou]

@@yourneighbourhoodclownwith8490 Hi! No it's still going on... I've seen a neurologist who didn't know.. and took some more blood tests. Nothing that would be causing this was present. The one blood value that is missing, is B6. It can give neurological symptoms both if it is too low, or too high. I'm getting that tested - I just manage to organise it. The neurologist has set up for me to do a test of the nerves using electrical shocks. I'm doing that on 1 Aug. I'm beginning to realise I'm on my own here! I've done lots of research. The neurologist simply said "these things happen sometimes with no clear reason". The other doctor got hung up on me losing weight and doing Keto. I've had some terrible problems with autoimmune diseases - I just want to be sure that this condition is not progressive, or autoimmune, such as Multiple sclerosis. It flares up sometimes, and sometimes subsides to just the underside of the feet. I'm hoping it's something silly like vitamin shortage/overdose. It's very distracting and is constantly on my mind. My CRP, which SW Int. Medicine commented on, has reduced, but the SR (other inflammatory value) remains at 20 - too high. I plan to take antibiotics and maybe some cortisone for a short period - just to rule that out too.... Bought it online since the Dr won't approve of taking it just as an experiment.. It's a mystery and it just came on overnight - for no reason I can understand. Other than this problem, I'm feeling better than ever! I'm clearly not sick. Let me know how it goes for you! Good luck and God bless!

There are a lot of contextual things that I do not know about you. So we his is not advice to you specifically. However a low holo-tc would mean you are lacking or low on the transporter.

Thank you very much for your informative videos on high B12. I have high B12 for over 2 years now. roughly about 2000. Got all liver tests done and seem ok. however, no other doctors would look into it why it's high. I also have several autoimmune illnesses and heart valve regurgitation. I continue to pursue researching and saw your video. It's surprising to find that it's an underestimated anomaly viewed by doctors. My doctors all said 'don't worry about it'. Based on my research, I initiated going to see a hematologist next. Through several blood tests, found out that I have MGUS: IgA kappa monoclonal protein. Since it's not high, i'm being monitored every six months. I'm still in search of the cause. I'm in the NY area. Would you be able to recommend someone I can see? or should I contact your office? Appreciate your help!

Hi, It's hard to say for sure. You should re-check the levels and make sure you are not taking any extra B12 when you do it again. If still as high, consider seeing a blood specialist, hematologist.

Dear doctor, How is it possible that an oral multivitamin can affect the levels of b12 ? I understand that the injections may have an impact however I don’t understand how the oral way can affect it since the body should excrete any excess. My result came back at 1490 and I have been taking 600 mcg of b12 since the last 5 months. Really appreciate your feedback.

[@swintegrative]

It doesn’t excrete all of the excess some is stored. Also it takes time to excrete it. So if u take it at 6 am and you have your blood drawn at 8 or 9 am there is not enough time to excrete it.

hi! thank you for these videos. i’ve been watching them.. back in august they found that i had slightly low b12 (around 300) and slightly anemic. i never took any supplements for either issue. yesterday they did another blood test to see how everything was ( i did not eat or take anything 10+ hours before my draw) a doctor has not gotten back to me yet but my b12 has increased to 1,200. and also my lymphocytes have increased above “normal” ( i am not sick, and have no infections). when comparing my results from august to now i noticed that my RBC’s have all SLIGHTLY increased. WBC’s have all slightly decreased ( besides lymphocytes which are above average) and my platelets have increased a little. i haven’t had any symptoms that i’ve noticed besides been napping a little more often, some night sweats & the pst 2 weeks felt very full after a small amount of food.. but i figured this was nothing related. i have no pain or anything though. i’m only 21. so i feel like i’m fine. but my doctor has not gotten back to me and it’s causing me now to stress out.. what do you think about this?

[@swintegrative]

Hi Keana, there are a lot of variables so it is hard to say from just this information what is going on with you. The main thing is I would not be too concerned about these results but I would not ignore them either. As a start, you should re-check your b12 level and wbc's. WBC's can fluctuate a lot from one test to the next.

[@KeanaConyers]

Southwest Integrative Medicine okay thank you. my doctor has been out on materinity leave till january. the doctor filling in said it’s from “eating foods with b12” and that nothing else further needs to happen. i’m not comfortable with that since i don’t even eat foods with a lot of b12 hence why i’ve always been low. i requested he refer me to a hematologist just to be safe instead of brushing me to the side saying there’s nothing further to do.

They will probably be more likely to re-do the test then if still off send to hematologist. Either way though you should re-check.

First I assume you don't take extra B12? If the answer is no then yes it is a good idea to do some tests. Some of the same reasons people have a diagnosis of M.E. and CFS can cause high TCN -1 and TCN-3 (B12 carrying proteins). In coordiation with your health care provider you should do a MMA and homocysteine to see if intracellular b12 if low (along with liver, kidney and white blood cell tests).

[@amarali1440]

Thank you 🙏

[@swintegrative]

Sounds interesting. The organic acid test typically looks at methylmalonic acid which is more sensitive way to check for B12. A high MMA indicated a deficiency. It is possible to have high serum b12 and low intracellular B12. You can get more details about this in my book amzn.to/3jVGvZf

[@sorsara78]

regarding the methylmalonic acid and homocysteine. do both need to be high in order to treat for B12 deficiency? what if one was high and one was normal? does it still mean B12 deficiency?

[@swintegrative]

Hi Sorsara78, This is a good question. Either being high suggests B12 deficiency. Methylmalonic acid is more specific to B12 though. Nothing is absolute but a high MMA is almost always B12 deficiency. High homocysteine can be other things. Normal or low MMA does not mean normal B12 but means there is not severe longstanding deficiency. Hope that helps.

Hi Laura O'Reilly, I recommend following up with the doctors and doing repeat testing of the B12 levels to show it is high multiple times. You can also ask for urinary methylmalonic acid test and homocysteine tests. The B12 being high does not cause symptoms and there is not definitive treatment for it. The reason B12 levels are high (whatever it is in your case), does cause symptoms. To find this reason, you have to be persistent and patient and find a doctor that is as well. In other words its a clue not a diagnosis.
