Considered as supplements, these are your caffeine fix taken in capsule form. They may have natural caffeine straight from the brewing process, while others may have synthetic or artificial caffeine.
Caffeine pills provide the same stimulating benefits as coffee and other caffeine beverages.
Note that caffeine pills aren’t exactly those caffeine powder you see in bulk from the retail stores. In fact, the US Food and Drug Administration or FDA considers caffeine powder as “potentially dangerous.”  Caffeine pills are generally safe, though there are some precautions to note, which we’ll talk about later.
This is a love story that most of us coffee lovers have with our cup of joe.
We can only love our java so much, and there will come a time when we have to have a little less than what we’ve been used to.
Parting ways is an arduous process filled with pain, pining, and pure anguish.
(Okay, that may be too much but you know what I mean.)
Romance calls this passion. Science calls this caffeine withdrawal.
How bad is caffeine withdrawal? People who have a caffeine habit may empathize with a scene of the 1931 production of Frankenstein, in which the mad scientist exults over the animation of his monster, exclaiming “It’s alive! It’s a alive, it’s alive!” I know I get animated in the morning after drinking my first cup of the ichor we call coffee.
Caffeinated products are wildly popular worldwide, used by as much as 90 percent of the adult population. An estimated 80 percent of American adults take caffeine in one product or another, and it’s estimated half of those people are prone to headaches for one reason or another. If you are among the caffeine users who get caffeine withdrawal headaches from coffee, tea or energy drinks, there are a few things you can do to minimize the pain.
Caffeine isn’t addictive, but it sure is habit-forming. You don’t hear about jonesing coffee addicts robbing stores and hijacking motorists to get money for a fix. That’s because while caffeine does cause dependence, it isn’t in the same category as opiates or alcohol.
That’s a good thing that caffeine, unlike alcohol and drugs, does not cause disease, crime, financial ruin, automobile and other types of accidents and a breakdown in social interactions because in the United States 90 percent of people take it in one form or another.
About 90 percent of American adults take caffeine daily. Half or more of them are subject to caffeine withdrawal symptoms when they don’t get a fix, including headaches, fatigue, drowsiness, depression and irritability.
This may not seem like much of a problem because caffeine and coffee users are like Charlton Heston and his guns: They’ll give up caffeine when someone takes their coffee from their cold, dead hands.
