Can you overdose on vitamin B12?
I take a multi-vitamin called Orange Trian that has a huge amount of B12. Was never that concerned since doctors recommend multi-vitamins all the time. But then I noticed the ingredients of that 5 Hour Energy drink that I occasionally use before a match and it has a crazy amount of B12 too. Yikes, 17000% of normal daily intake got me thinking. Could this be dangerous?
