As cliché as it might sound, the city really can be a jungle. Between subway seat-stealing sharks, carnivorous coworkers and prideful packs of hyena-like shopgirls, it's easy to feel like a quivering antelope fearfully grazing near the watering hole/ water cooler. So how can you be sharp amongst so many predators?

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.
