What are the side effects of too much Vitamin B12?


Usually, there are no side effects from ingesting too many Vitamin B12 supplements because excess can be excreted in your urine. However, some high doses of B-complex vitamins like pyridoxine (B6) have been associated with Neuropathy/nerve damage. If your serum B12 is a lot higher than the normal level, you should back down or stop B12 supplementation.
