Beware B Vitamin Toxicity!
0

52 posts in this topic

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.

IMHO

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.

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.

I am not doubting your statement--or you, hon--but where did you read this?

I would like to know --for my own knowledge. Thanks.

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

    • Here is another point.  My hubby went gluten-free per the poor advice of his GP and my allergist.  It worked.  A tough first year, but he got well.  Thirteen years later, I got diagnosed with celiac disease.  I was shocked!  😱.   Does he have celiac disease?  We will never know because we can not afford to have him do a challenge.  He refuses and I can not blame him.  He knows he will be very sick!   The point?  I am so lucky that we both can not have gluten.  I never worry about him making me sick or vice versa. We made the house completely gluten free for  1) our health and 2) the fact that our kid started helping in the kitchen. Kids make mistakes and I personally need a safe haven.  She wants gluten?  I buy prepackaged stuff and she takes it to school.  All parties and events at my house are gluten free.  Lots of work, but we stay healthy.  She does not have celiac disease.  When she is preparing for a celiac test,  I send her on the porch to eat cookies or bread or whatever floats her boat.  We travel in a gluten-free RV.  I have five sizes of ice chests.  We just have to be prepared for any event.   How can we live this way?   We love feeling good.
    • Freize is right, you need to think about your environment.   Based on that a study I posted for you, you will note that the patients who were diagnosed with refractory celiac disease and THOUGHT they were diet compliant found that they WERE NOT diet compliant.  How is this possible?   This is way out there, but unless you are growing all your own food, you don't really know if it is gluten free.  In the US, we do have laws to help protect our food supplies (no perfect, but a start).    I can not speak for India.  For example, what about your soy?  It can be contaminated by the farmer as it is often rotated with wheat.  Here is an article by Jane Anderson who has celiac disease.  She is very strict as she has DH (celiac rash), but she cites Trisha Thompson who tests foods for gluton contamination, The gluten-free WatchDog (like Consumer reports).  She found that soy which is naturally gluten free, but can be cross contaminated by wheat: https://www.verywell.com/is-soy-gluten-free-562371 so, start thinking about your food supply. As far as a negative TTG IGA or TTG IGG?  I test negative to both.  Only the DGP IGA has ever been elevated in my blood tests (even repeats), yet I had a Marsh Stage IIIIB on my biopsy.  Have you had a DGP IGG?  (I do not see this in your posting).   http://www.cureceliacdisease.org/screening/ These additonal celiac tests might help you feel confident that you have celiac disease and not something else that is damaging your villi.  But remember, some  folks have celiac disease even with negative blood.  I am not IGA deficient, so this is an area I have not researched.  Not to mention that some celiac researchers do not think that the celiac  antibodies tests are good for diet compliancy.   I wish I had better answers for you.  Try a grain free, whole foods diet of meats, fish, eggs, and vegetables for a while.  All food prepared by you. Who cooks your food now?  Is your home gluten free?  Cross contamination at home?  Kissing a loved one.  We had a doctor with celiac disease who was getting glutened by her little children who were consuming gluten!  
    • I won't say I will never eat out but I can't see me eating out for the foreseeable future. Even then, I will most likely only eat at a dedicated gluten free place. I am extremely sensitive to the tiniest amount of gluten and it's just not worth the risk to me. Eating out is playing Russian Roulette as far as I'm concerned and I'm not ready to play that game yet.
    • You are right. The weirdest part is that I feel fine, however, I am sure cross-contamination is doing damage even when we don't think it is.
