Caffeine can play a significant role in the lives of people with demanding days that require an extra pick-me-up when that midday slump kicks in. But do we all understand the hazards involved with consuming too much caffeine?

An upstate New York coffee company is boasting it has the "World's Strongest Coffee" with close to 200 percent more caffeine than your normal cup of coffee, The Daily Mail reported. "Death Wish" coffee is being sold at $19.99 per one pound bag with a 60-day refund guarantee claiming it is the strongest cup of coffee you will ever drink or you'll get your money back.

On its website, the company states its higher caffeine content comes from the types of coffee beans it uses compared to high-end coffee makers like Dunkin' Donuts and Starbucks.

While most coffee producers use the full flavored Arabica beans, "Death Wish" coffee comes from Robusta beans that have a much harsher taste, but contain a lot more caffeine.

Coffee beans account for the majority of caffeine intake an average person consumes each year. Classified as a stimulant and a drug, caffeine consumption should be monitored to ensure a healthy balance in the human body.

Since it is a stimulant, too much caffeine can over work your brain resulting in loss of sleep and in some cases insomnia. It can also cause a physical dependence which can bring about withdrawal symptoms that include drowsiness, lack of energy, headaches, dizziness and irritability.

Caffeine has also been linked to a spike in blood pressure which is why most physicians warn people with already high blood pressure to monitor how much coffee they're drinking.

Most experts say the healthiest amount of caffeine someone should take in a day is between 300 and 400 milligrams.
