Many energy drinks tout being packed with B vitamins for an energizing boost. Sounds healthy, right? Well, it’s not that simple. Downing these drinks can put you in danger of ODing on B, which can cause nausea, hives, vomiting, mental dysfunction, nerve damage and liver issues not too far down the road. Yikes! Kick the can and bulk up on better bets for B such as peppers, cabbage, asparagus, spinach, clams, mushrooms, tea and coffee.
