ELI5: 5 Hour Energy drinks have 8333% of your daily value of vitamin B12. What affect does this have on your body?

Not much. B12 is useful to your body when you exert a lot of energy and if your body has issues absorbing B12 you'll tend to sleep a lot. However it's not fat soluble so you actually just urinate out the excess that your body doesn't need. Your urine maybe a darker yellow due to the excess B12 even if you are well hydrated.
