Well, you could do like the noble gecko and try to camouflage into your surroundings, or you can act like a squid on attack and shoot spurts of ink at your foes, or you could simply drop a Berocca tablet into a glass of water — and soon you'll be on top of your game.

Berocca is an orange-flavored effervescent tablet. It features a unique combination of key ingredients, including vitamin B-complex to support physical energy by converting food to fuel and a Guarana blend that helps support mental sharpness.* Each tablet also includes vitamin C, Biotin, folic acid, zinc, calcium and magnesium.

Berocca is now available exclusively at Duane Reade stores in New York City — and online for the entire U.S. Head here for more information.
