The cup of coffee that could cause heart palpitations

A 12-ounce cup of

Black Insomnia is now available for purchase on Amazon.

According to the U.S. Food and Drug Administration, adults should not have more than 400 milligrams of caffeine in one day, as too much consumption could lead to "headaches, insomnia, muscle tremors, irritability, and rapid heartbeat".

The "world's strongest coffee" is so strong, it will drive you over the daily caffeine limit and give you heart palpitations.

A 12-ounce cup would have more than 700 milligrams of caffeine. One 12-fluid-ounce (355-milliliter) cup contains almost double the recommended daily allowance of caffeine. Black Insomnia Coffee is officially the strongest coffee in the world - strong enough to be unsafe, according to CNN. It has to be the strongest but simultaneously it should not exceed the world guidelines.

Cape Town, South Africa-based Black Insomnia proudly acknowledges its product is in no way part of a healthy, balanced lifestyle.

At least that's the claim of the not-so-subtly-named Black Insomnia, which contends it has scientific proof its brew packs multiple times the punch of a normal cup of Joe. "This makes it easier to consume more caffeine than you intend to and effects can range from mild to severe, for example, jitteriness, nervousness, restlessness and trouble sleeping".

Death Wish said they were "not scared" about the competition from these "new kids on the block".

The coffee went on sale in the US this week, and 16-ounce bags of it are also available online, Tech Times noted.

Caffeine Informer, an information website that collates data on coffee, lists Black Insomnia as one of the "Most Dangerous Caffeinated Products".
