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.
If you’re trying to lose weight (or at least not gain a few extra pounds), then the best thing to do is eat healthy and go to the gym more religiously, right?
But if you’ve been going at it for a while now and haven’t been seeing much progress, then you may want to look into something else.
Like your coffee consumption.
Now you may ask: what does an innocent cup of joe have to do with weight gain?
Let me tell you.
It’s not as innocent as it seem.
That cup of coffee you buy on your way to work? It may be sneaking in a few extra calories (more than you’d like and expect). And if you buy more than one cup a day, you may be racking up a few calories from a “dessert” that disguises itself as your go-to caffeine fix.
Caffeine is known to bring a great deal of health benefits day in and day out. From helping you get clear, misty-looking skin, carry a sprightly vibe throughout the day, or win the gold in your favorite sport, caffeine just keeps winning the java-lover in you.
But it’s not all rainbows and butterflies. Sometimes, having one too many cups of joe leads to unwanted side effects, turning a regular caffeine hit into a love-hate relationship.
Upset tummy is perhaps one of the *supposedly* negative effects of being too caffeine-happy. Hear a growling tummy or feel a nagging pain in the stomach? Must be your fourth cup of coffee, right?
But is caffeine really to blame?
One of the common questions about caffeine is whether it makes you dehydrated. Some think that coffee and other caffeinated beverages make them pee more than usual, perhaps making them believe that they’re losing fluids. Some though think that it doesn’t make a dent on their fluid intake.
If we were to turn these myths, urban legends, “feelings” and observations (however way you want to call it) into something scientific, then the million dollar question is…
Mixing up caffeine and antibiotics – yay or nay?
If you’re under medication, specifically antibiotics, but is yearning to reach for that cup of joe, then this is a very important question.
According to a report by the New York Times, coffee can prevent some of the medications from working.  Depending on the drug you’re taking, coffee – or any other caffeine source – can either amplify its effects, increase the side effects, or block the absorption.
Some interactions are even considered lethal, while others may only need a consultation with a medical professional.
With the help of rx.com, we’ve listed down a few drugs that may have direct impact in your system when mixed with caffeine. 
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.
Caffeine. Sometimes, it’s a love-hate relationship. It keeps us awake when we need to (read: all-nighters), but it can also keep us more alert than we’re supposed to.
For something we consume regularly, caffeine tends to consume us back. We enjoy it so much to have one, two, three cups of our favorite caffeinated drink, only to realize the consequence when that 1 AM moment hits.
Caffeine can be a much-needed boost – that’s common knowledge – but we’ve never really paid much attention to how it works.
That’s what this article’s for. We’re going to dive deep into caffeine and how it affects sleep.
Did you know that the benefits of coffee go beyond helping you get a second wind during that afternoon slump? It actually helps you get smooth, glowing skin!
Sounds like your typical skin care ad right? But here me out.
Coffee's properties give natural benefits for the skin. And no, not by drinking more cups of joe. It's when you actually apply it on your skin.
Those innocuous-looking coffee ground can actually become a coffee scrub for your face and body!
This isn't the fad of the year - it's actually been done for years because of the things it can do for your skin.
Some of our favorite athletes are just like us – they have their everyday caffeine regimenand love it.
But did you know that some athletes don’t just have it as part of their morning routine; they also use it to boost sports performance?
In fact, three-fourths of the world’s elite athletes take advantage of caffeine’s performance-enhancing properties.
But have athletes always been allowed to drink coffee and other products with caffeine in them, especially right before the sport?
If so, how much are they allowed to consume?
Feeling down? Going through mood swings? Having one of those days?
What if I told you that you can turn your day around as easy as getting a caffeine fix?
I'm not pulling this out of a hat. Science suggests that caffeine is not just a stimulant that keeps you alert, it can also improve your mood and help you become a walking ball of sunshine. This may seem like a tall order for caffeine but wait ‘til you order a tall cup of coffee and experience it yourself!
Based on a review conducted by A. Nehlig, having 75mg of caffeine (a cup of coffee) every 4 hours can lead to a “pattern of sustained improvement of mood over the day.” It can increase alertness and well-being, help concentration, improve mood and limit depression.

In the 1990s, the Loughborough researchers measured brain waves of subjects in driving simulators. The caffeine nap worked better than anything at eliminating mid-afternoon drowsiness and preventing driving errors than in all of the other controlled groups they studied.
It seems caffeine may enhance memory and learning, but not if it is taken before the lesson is to be learned. Research from a few years ago says caffeine should be taken after that important business meeting, crucial college lecture or other knowledge-imparting event you need to recall.
Some studies show a benefit from caffeine on memory, some show none. Same with alcohol. But it seems scientists find with few exceptions that good diets promote healthy minds and bodies.
