Origins of Coffee:

Health Benefits of Coffee, Based on Science, Legend has it that Coffee was discovered by an Ethiopian goat herder who took his goats out to graze and when some of his goats bit off some berries from an evergreen shrub and suddenly appeared to get hyperactive. 

As the legend goes, the herder carried tales of the incident to the local monastery about the berries he found and the unusual effect they had on his goats when consumed. The abbot was intrigued and decided to try out the berries for himself and consumed them after turning them into a drink.

He found that they helped him to stay alert during his prayers and shared this with the other monks. Caffeine is the naturally occurring substance in the coffee bean that gives a dose of energy and makes the drinker more alert. The monks took to consuming coffee regularly, and this was the starting point that led to coffee reaching the heights of popularity it enjoys today.  

Popular Caffeine Products

It is essential to take only the recommended dosage to avoid any complications. 

Decaf Coffee:
