Caffeine has been known to give a whole heap of benefits - from giving that first jolt in the morning to keeping high concentration and perky vibe throughout the day.
Coffee may be the most popular, but it can also come from caffeine mints and pills, chocolate (beverage and milk bars alike), cake, yogurt, and tea!
Yes - tea. That seemingly innocuous cup of tea can give you that much-needed boost.

He said this caffeine was created in coffee beans on a hillside in the tropics. “Slowly and quietly, driven by the energy of sunlight, it formed inside coffee beans hanging on thousands of trees, most likely in Brazil or Vietnam,” Charles wrote.
“Those beans were harvested, loaded on ships bound for the port of Houston, Texas, and ended up at a factory within sight of downtown Houston: Atlantic Coffee Solutions. It’s owned by one of the world’s largest coffee traders, ECOM Agroindustrial Corp., which is based in Switzerland.”
