Vitamin B12 overdose: Too much vitamin B12 can cause mild diarrhea, skin rashes, hives, breathing problems, heart palpitations, panic attacks, and insomnia.

What is the definition or description of: vitamin B12 deficiency?

Dr. Daniel Royal
Board Certified, Holistic Medicine

124K people helped

LACK OF ABSORPTION: B12 deficiency can be due to a lack of absorption or intake from diet. Since B12 is primarily found in animal products (e.g., dairy, egg, meat, etc.) vegetarians are more at risk. A deficiency is suspected when rbcs increase in size (e.g., high MCV and/or MCH in cbc) and can cause megaloblastic anemia. Symptoms can include fatigue and neuropathy. It is best corrected with methyl B12 by injection. ...Read more

GI problem?: Based on the low levels of several vitamins, I would be concerned about some form of malabsorption syndrome. Do you have chronic diarrhea? Pernicious anemia from low B12? Osteomalacia from low Vit D? You probably need to take some levothyroxine (but will you absorb this?). Sounds like your doctor is giving you vitamins, which is good, but what is the cause of all this? ...Read more

What is the best use for vitamin b12?

Absolutely: B12 in the form of methyl cobalamin is necessary for numerous biochemical pathways. It can prevent psychoses, nerve tissue degeneration and megaloblastic anemia. Methyl B12 can be given safely at doses up to 3mg intramuscularly and can be given weekly in those patients who cannot absorb it through the GI tract. Otherwise, 2mg oraly is optimal. There are no known side-effects of having to much. ...Read more
