Convenience stores in refrigerated section, and likely stores that carry Japanese foods, have Lipovitan which has Vitamin B and royal jelly which is what bees feed the queen bee. I think Vitamin B has something to do with energy production. Tastes pretty good like very small dose of soda.
I used to bring Sobe Lifewater, no idea if they still are in business, to work and drink it later in the day for a boost to keep plugging away. It also had Vitamin B and other nutrients.
