Hi all

I am very concerned about if I take Vitamin B12 at 50mcg tablet oral. Is it too much? I usually take 3mcg or nothing at all. I know it is so much above the RDA. Just now i just took 50mcg B12 for the first time and i would like to ask, how long would it take to see the therapeutic effects? The effects can be mild like helping me to improve my concentration, memory or perhaps the long term benefits? Thank you for all the advices. Greatly appreciated. Is there toxicity or side effects at this dosage of 50mcg? Thank you so much!!

Hi,

Not sure on the amount, I have pernicous anemia, so I get injections, every 6 to 8weeks. I'm not sure in tablet form what amount, although after I get it I have alot of energy, and not so draggy. I think a health food store could help you.

oh i see
i don't have pernicious anemaia
But i am sure i am fatigue easily before i started my vitamins therapy. But now i have really seen alot of improvements. I get more energy and thus my mood better..

B-12 is water soluble. Whatever your body doesn't use, it will get rid of. I haven't heard of any toxicity levels with B-12.

No known toxicity to high levels of B12. It is one vit that you use very little of and lose very little of. You can take whatever you are comfortable with. I have pernicious anemia so I give myself injections every 3 weeks and also a sublingual B12 everyday.
