Re: B12 overdose? - Don't Worry!
I found this site whilst looking to see if I have anything to worry about with the symptoms I am experiencing after a suspected (Hydrocobalamin) B12 overdose...
I can firsly put most peoples minds at rest by saying that if you are taking B12 in tablet form you will certainly not have overdosed, this includes anyone who consumes an entire bottle of industrial strength B12...
The body only absorbs minute amounts of B12 from the food and drink you consume, A glass of milk contains 15% of the B12 RDA. Whilst 100g of Liver contains 3700% of the B12 RDA...
As you see most meat eaters consume at least 10,000% the RDA in any one day, but only a small amount is actually absorbed in to the bloodstream.
Alcohol absorbs B12 from the system, which is why people crave kababs and meaty foods after a night of drinking...
The body is capable of storing 10 years worth of B12 for anyone whi is T-Total
My situation is slightly more complex, I suffer from a B12 deficiency (penicious anemia) due to my diet, I have been a strict Vegan for 17 Years now. For a number of years I have been recieving B12 (Hydrocobalamin) injections direct in to my arm muscles for slow release and absorbsion into the system.
I believe that at the drop in centre the nurse may have stuffed up my Injection, it was not painfull as usual (it's meant to hurt) and 12 hours later i'm experiencing some awkward side effects, which makes me think that the entire 3 months dose went straight into my bloodstream...
Side effects are as follows, Numbness and pins an needles in all my extremities, soar stomach (actually muscle pain), a feeling of being attached to a low voltage current (feels like you have just been scared, the shivering feeling you get afterwards), slightly blurry vision (but only when I change focus), a slightly racing mind (but no energy boost) and a tight chest (whilst i've been writing this post).
If the effects continue till morning I will consult my doctor, but for now I thought i'd let people know they are safe...
Thanks,
Mixtlupus.

Hi, what sources do you have that back up this? Have you read the earlier posts in this thread?

What RDA are you referring to, and where is the info that documents that meat eaters (which not at all should be any reference for healthy living, by the way), consumes 100 times as much? This would mean, for example that if the RDA is 3 mcg, your suggestion would mean that meat eaters consume 300 mcg pr day....

You are experiencing all this and say that it's safe to consumes an entire bottle of industrial strength B12? If I'd experience all that, I'd call a doctor immediately.....!

It is a fact that most people consume what would be considered an overdodse on a daily basis, please note that he key word is consume.

The RDA as set out by the FDA, B12 levels are still high in a non healthy diet. Most people eat at least 100g of meat per day, not to mention that most foods (eg. cerials) are now fortified... 100g of cornflakes with skimmed milk constitutes 85% of the RDA, all the figures I mentioned are freely available on-line on many sites such as the FDA site...

Remember their is a big difference between consuming B12 (of which a small amount is absorbed and the rest passed in to your bowel) and having it injected straight into your bloodstream (bypassing the bodys natrual ability to only absorb whats needed), my body is currently burning the excess B12 from my system, I'm feeling much better if not quite hot (In my line of work it's not always possible to get time off which is why i'm waiting till morning), as a long term sufferer of a thyrod desease I've felt much worse...
I've had a deficiency for seven years now, I like to know as much as possible about the issues I may have so much of my knowledge has been through talking with doctors.
