Beware B Vitamin Toxicity!


SGRhapsodos

Recommended Posts

SGRhapsodos Rookie

Celiacs out there who are feeling dizzy, bloated, having seizures, constipated, or having diarrhea: you may be experiencing b complex toxicity. A lot of us celiacs are prescribed/recommended/self medicate with vitamin b supplements and assume that they're 'safe'. It's not true. A lot of these supplements have mega doses of the daily requirements of these vitamins that can be extremely dangerous if taken over a long period of time. I have been taking huge doses of b vitamins and have been having these weird symptoms for a while. the worst would have to be vitamin b6 which had caused me a lot of central nervous system problems such as convulsions. A lot of the other vitamin can cause kidney problems, sugar/protein metabolism problems and GI problems to name a few. I thought I was getting Glutened all the time, but that's really hard in my case because I don't eat grains or legumes that are cc'd. Plus, I felt like complete crap yesterday after taking my b complex supplements. Check with your doctors or if you think the b complexes may be causing your problems STOP taking them. There are b vitamins in a lot of foods. The only one that's relatively safe is b12 and you still have to be careful with commercial mega doses. I hope this helps some people.

Thank you for posting this.

I have been saying this on threads for a while, but no one wants to hear it. :) Everyone says "but they are water-soluble". :rolleyes: ...meaning they are not stored in the body. That's true, but that also means it is important to provide an adequate supply through a balanced diet.

That does not mean they are not CIRCULATING in your system.

B-complexes often cause nausea and stomach pain.

You can become toxic from too many vitamins, minerals and herbal supplements, despite what people say about "It's no problem, you are just peeing them out".

Unless you have a real deficiency, you may be doing more harm than good by mega-dosing on your own.IMHO

You should only take higher doses of vitamins if you are severely deficient and your levels should be monitored closely via blood work and under a doctor's care.

And mega-doses of Bs are not the only danger.

Too much A, E, zinc --really, too much of anything can cause problems.

Unless you have a B-12 deficiency, there is no need to take this vitamin in excess either.

Instead of helping with parasthesia, mega-doses of B6 and/or B-12 can can cause it.

The Bs work synergistically in the body. Too much of one can unbalance the others. That is why they are marketed in B-COMPLEXES.

It happened to me. It was suggested (by one doctor and a ND) that I take B6 for nerve pain, B5 for adrenal support, Biotin (B7) for hair loss and I was already taking a B complex (200 mg) on my own; then, my PC doctor told me to take Folic acid (B9) by prescription (for anemia) and high doses of sublingual B-12 (for anemia) and soon, I had INCREASED burning nerve pain (the very thing I was trying to resolve because I BURNED with neuropathy for 3 years)and I felt sick to my stomach constantly. :blink:

My new GI doctor took one look at the list of supplements I was taking, saw my recent blood work with very high B-12 and Folate levels and said "Stop taking all those things!! You're toxic!"

It took a few months to get the levels back to within normal range and all that excess burning and nausea stopped.

In the case of SELF -mega-dosing vitamins, MORE is not necessarily better.

Vitainims & minerals can be toxic as well as drugs. I don't believe in mega dosing anything..unless it is a life & death situation....then I may try anything!

I had a reaction to B-6 was not taking extra just what was in a multi I was taking..Small amount but my body just didn't need it so the body rebelled...I find taking the individual supplements works best for me & not multi's..This way I can control ...

As they say" everything in moderation" & that means everything...Some people think or feel a little is good but more is better!

Personally, I really HATE reading posts like this because they could actually harm someone if they actually have vitamin deficiencies and read the original post and just stop taking their supplements. Since you are not a medical professional, it may have been better to add that supplementing vitamins should be done with your doctor's knowledge and blood tests to monitor vitamin levels rather than to suggest that someone discontinue a supplement they are taking. Especially if they are taking it because they were instructed to by a doctor for an actual deficiency. Because those mega doses of b12 that you are so hard on are the only thing thing that is keeping me from becoming anemic and stops the neuropathy due to the deficiency.

Wow! I think once the GI tract heals, one starts absorbing these vitamins from foods and you don't need the supplements. Just eating enough whole foods should be enough.

Really? You really think anyone would suddenly stop taking a medically- prescribed supplement based on this thread? :blink:

No one is "being hard on B-12." Not at all-- You did not read what I said very carefully. IMHO

I had a B-12 deficiency for YEARS. Now, I do not. I am HIGH in B-12. Too high. Why? Absorption returned and I did not need it. I was toxic from continuing the dosage --and I was taking it upon the advice of a doctor!

I think we all stated pretty clearly that we were relaying :

our experiences

and that even under a doctors' supervision, this still happened

and in no way did anyone say "Stop taking all your supplements right now!"

We said: Be careful.

We suggested: Don't SELF mega-dose unnecessarily.

And the OP also said "check with your doctors".

I said: If you have a deficiency proven from blood work...etc.

No one is playing doctor.

No one should suddenly stop doing anything that has been medically prescribed.

I do not know how you interpreted anything else out of these posts. That was not my intention at all!

I'll say it again:

If you have PROVEN B-12 anemia, you should take an appropriate dosage of this vitamin as prescribed by your doctor.

And have follow up blood work done to monitor the levels.

I only suggested people do NOT mega-dose this vitamin --or any vitamin--without careful monitoring.

IMHO

I never claimed to be a medical professional. I just say for those of us who are still having problems after going gluten-free for a while some supplements may be to blame. I don't disagree with the fact that some people are severely malnourished and do need very high doses of supplements, but some of us with healing guts may no need them. Depends on the individual's needs. I personally had to self prescribe b vitamins because upon being diagnosed by my first GI doctor I was given a list of foods and sent packing. No advice on how to get my health back, etc. The supplements helped at first, but then became toxic as my gut healed. That was MY personal experience and I was just putting it out there to see if anyone could relate to it.

Disclaimer: do ask your doctor before stopping any supplements prescribed by him/her. Is everyone happy now?!

However, do listen to ur body if you don't feel well and do bring it to the doctor's attention. Most doctors don't ask the amounts (milligrams) that you're taking. Nobody asked me. A lot of doctors don't care or are not educated in the dangers of vitamin overdose. Everyone is different. If you feel that the supplements help, then take them by all means.

squirmingitch Veteran

I too believe in getting all your vitamins & minerals from a balanced diet & have always felt that way. In fact my mom taught us that. However, for right now, until my gut heals & I can get the benefit from my food; I need & feel much better from taking supplements. I am going to stop them as soon as it's safe to do so. I'm looking forward to that day.

It happened to me, too--and I WAS under two doctor's supervision.

I think you have been very clear about your good intentions in this thread, hon--no need to keep defending it. You said nothing wrong that I can see! FWIW :)

It's all good! ;)

I may just point out that the serum B12 test is not the best at identifying a B12 deficiency. Most of the ranges (in the U.S.) are too low given that many people with higher LEVELS still have the symptoms of a deficiency. So, while having testing done should be helpful... make sure it's the right kind because not all doctors are clued in on vitamins and minerals. :)

Thanks for making us aware of this.

Could It Be B12 – An Epidemic of Misdiagnoses - 2nd Edition by Sally M. Pacholok, R.N., B.S.N. Jeffrey J. Stuart, D.O.

I should add: the serum b12 test ALONE is not the best.

I see, so what additional tests ARE recommended, then? or how do they determine if it is NOT pernicious anemia? and what is their research based on--do they say?? thanks! you've got my attention...

From what I remember they suggested the serum b12, urinary MMA and homocysteine... I'll have to go back and look as I think I might be forgetting one. They identified people whose serum b12 levels fall under 500 as in the "gray zone." They spoke a lot about the symptoms - levels connection and found that people whose levels fall under 500 (particularly levels under 450) could benefit from supplementation. There are lists of references usually 2-3 pages long after every chapter. I could go through and type them all out if you'd like, but that would be a little tedious. :lol:

Oh - I will have to go back and look at the pernicious anemia bit as I do not want to relay the wrong info.

Good to know! I'm still taking the b12 supplement until I feel like I don't need it anymore. The one I've definitely stopped is the b6 because I was having those convulsions. I'm waiting to pee it out now. Been to the bathroom like 5 times today and it's only 11 am here lol. Thanks for the info. I love these forums because you guys have more info than any doctor. Seriously, my first GI doctor told me to go online and that's what I did. Saved my life.

Do you have a scanner? You could scan it & then upload it here???????? Save an awful lot of typing.

Smart thinking, there. B)

Our old one doesn't work and I'm not entirely sure where the scanner is located in our new one... but my stomach is rumbling and telling me it's time for breakfast. I will figure it out though! :)

There's wonderful safe vitamin guidelines on the Internet. I know some docs have prescribed large amounts to patients who are struggling to absorb. Many of us really do need these vits to help us regain our health but like the original post says we do all have to be careful with certain vitamins but that should not scare off anyone in need.

B vits have wonderful benefits, not just for people who are deficient. Not long ago I was in a doc's office here in Germany getting a treatment for my back. One of the things the German doc told me is that they use B and C vitamins for numbness and tingling for nerve pain. They put a whole IV of vits thru me and I felt wonderful!

Diabetics, HIV suffers, MS patients, etc find relief from nerve pain using specially formulated b complexes. I think you have to read the labels and stay within the limits provided unless you are under a doc's care for anything higher. If you are supplementing I think it is a good idea to have regular blood tests to check your levels.

I was a bit shocked at my last doc appt when he told me my D was slightly elevated. I didn't even know how but that is something I have to be careful with because I have problems with kidney stones. And me the sun worshipper!

Pernicious anemia is a decrease in red blood cells that occurs when your intestines cannot properly absorb vitamin B12.

No need to do all that typing or scanning! Too much work. I just wanted to know HOW she came up with the additional tests that she says should be used IN connection with the serum B-12 test ?

I am just curious!

Elevated homocysteine levels can occur for a variety of reasons (post-menopausal women for example can have elevated levels)

but in essence, what you are saying is,

if a doctor suspects a B-12 def and the B-12 levels are "within normal range" and the patient still has B-12 symptoms (which mimic everything from a stroke to Alzheimer's), there are other tests that may help determine a B-12 def?

Yes and

I think it is very important to note that neuropathy is caused by many medical conditions, like MS and diabetes and shingles, etc. ---not just a B-12 deficiency.

So whenever a new person comes on here and says "I have numbness and tingling", many members say "Take B-12!" ...but,

that is not necessarily wise because we do not know the CAUSE of that person's neuropathic pain.

What if it's something else and the member just blindly supps with mega-doses of B-12??

Yes, it is probably from the celiac--but what if it is something ELSE? Also, someone could throw all the vitamin B-12 in the world down there, but if the person does not determine the CAUSE of those symptoms, what good does it do?

I have high levels of B-12 now ---and I still have neuropathic pain, for example.

IMHO

      I’m sorry you’re going through all of this. It sounds very stressful, especially when you feel that your symptoms are not being taken seriously. Until you are seen next week, it may help to keep the focus very practical: take clear photos of the skin sores, write down a timeline of symptoms, list all medicines, eye drops, supplements, implants/leak history, and any test results, and bring that to the dermatologist. If there is drainage, spreading redness, fever, worsening pain, eye involvement, or signs of infection, that needs prompt medical care. I would be cautious about assuming parasites or staph without testing, and also cautious with new supplements or putting vitamin C directly on sores, since irritated skin can get worse. A dermatologist can culture lesions, biopsy if needed, and refer to infectious disease if the findings point that way. On the celiac side, I understand your concern for your son, but being HLA-DQ2 positive does not by itself mean he has celiac disease; it means he has a genetic risk. If he is eating gluten now, this is actually the best time for proper celiac blood testing before he tries a gluten-free diet. His symptoms, weight, congestion, and family history are worth discussing with a gastroenterologist, but he should not be told he has celiac based only on HLA status. For your own care, try to keep pushing for objective testing and clear documentation in your records, because that is often what gets doctors to take the next step.
    • Scott Adams
      You are not being unreasonable. A negative celiac blood test after 25 years gluten-free does not rule out celiac disease, because the antibodies usually fall once gluten is removed. It may simply show that your gluten-free diet is working. I would ask the doctor to add a clear note to your chart stating that the test was done while you were strictly gluten-free, that you have a long history of dermatitis herpetiformis and strong clinical response to the gluten-free diet, and that celiac disease remains your working diagnosis unless properly reassessed with a supervised gluten challenge, which you may not want or need at this stage. This should help prevent future confusion. It is understandable to feel frustrated, especially after decades of being dismissed, but this may be fixable with a calm conversation and a chart correction rather than changing doctors.

      I went to ER on the 30th because I didn't want to wait and saw dr at desk for intake. I went for NOTHING!. ER Dr was very nice but made it seem as if I was a nut case rater than coming in for real issues calmly explaining its staph! Staph,  by look no blood test, no skin test. No looking in my nose and throat was given a prescription for jock cream and some pills ! I made the mistake of saying Im waiting on Infectious disease. She asked how did I get referral and I said I did it online.The next day I checked the status and it was denied! I did get  a referral to the dermatology office i went to last year that over charged me and did a biopsy on me stating inconclusive! I went to another dermatologist and he stated I should see Infectious disease at place i put in referral. With that I contacted that dermatologist and waiting to see if he thinks dermatology or Infectious disease is the route.I do have appointment for dermatology next week.Until then i did purchase Zahler paraGuard advance intestinal  flora support  from Sprouts. Im also very alarmed that the fact celiac isn't addressed properly infact its downplayed. When I had my son tested for HLA-DQ2 and it came out positive because he is eating everything and he is extremely skinny but he isn't dealing with severe diagestive issues because thats all he knows NOW or yet because he is still young 21.I too didn't know any difference when i was that age because thats all we know.Life changes will get him in latter years im afraid because what im dealing with.That scares me.The specialist we went to was only about congestion he is getting.He is getting congestion because he is eating what he isn't supposed too! Zero talk about celiac and HLA-DQ2 positive. Only talk was he is congested because we live in the Valley! They wanted to do surgery! I did write again to our district leader considering when I did call, the guy stated he knew all about celiac. I really wanted to tell him NO YOU DON'T but held my tongue. For my skin sores the cream given didn't do anything because ive also had in past.Ive been putting liquid vitamin c on it and taking vitamins which is making a little difference just with the last few days of doing.

      I have been Gluten Free for 25 years and havent eaten gluten knowingly during that time.   Such a rocky life, I have had issues since I was 16 when physicians stated I needed to see a psychiatrist. I am now 70 years old. I also had Dermatitis herpetiformis. I had negative tests on biopsy, blood test etc but no doctor mentioned that I needed to do a gluten challenge. I went on an elimination diet and found relief on the Dermatitis within a month. I have no doubt that I am celiac and very sensitive now. Now my issue is that I changed physicians due to retirement and he performed a blood test and included a celiac test. I was very upset because I did not request the test and had not been eating gluten for 25 years. Of course the test was negative.  My question - Will this cause me any issues with health treatment if my records now have that I dont have celiac? I like this physician and I am appalled that he performed the test. (he told me his brother is also celiac).  I feel that we are still living in the dark ages. I dont want to cause problems because I rarely need health treatment since I live a fairly healthy lifestyle.  Since I am at this age and been through so much getting to this point am I being unreasonable for being upset? I am not expecting to see this physician for another 2 months.  Need to know if I can expect issues with future treatments. How can a physician not know about the gluten challenge this day and age?
