Most people drink a cup of coffee first thing in the morning. The tantalizing aroma and the strong, robust taste of coffee are just uplifting. Coffee is not just a beverage to some; it is a cup of hope and reassurance which could be highly addictive. Most of us are so hooked on coffee and its kick, that often we look for the most caffeinated coffee drinks. And currently, Black Insomnia coffee holds the title.
It is said the stronger the coffee is, the more mental clarity and focus it provides. Therefore, when it comes to an important day that demands our utmost attention, we need our coffee fix—and darker the hue, the better.

The FDA recommends no more than 400 milligrams of caffeine per day, which is four to five cups of a regular blend of coffee. Until a few years ago, that number was just 300 milligrams per day, so take a note. Nevertheless, coffee is still a widely popular stimulant.

There is a reason why we find a cup of cappuccino or an espresso so appealing. You see, coffee acts as a central nervous system stimulant. It can fight drowsiness because caffeine acts as an adenosine receptor antagonist.
Adenosine is an important sleep-regulating hormone which facilitates sleep by binding to its receptors and slowing down neural activity.
Side Effects of Consuming Too Much Caffeine
Aside from its ability to perk us up, coffee, or rather the caffeine is not healthy. Caffeine causes acidity and may trigger heartburn or acid reflex. It can also increase blood pressure levels, leading to irregular heartbeats and hyperventilation.
Also, caffeine may also interfere with calcium absorption and metabolism. Pregnant women should refrain from caffeine, as too much caffeine can also cause slowed fetal growth and increase the risk of miscarriage.
