Science of Caffeine

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.” [1] Caffeine pills are generally safe, though there are some precautions to note, which we’ll talk about later.

You have it every day. You know exactly what to tell the barista the moment you step into the café.

Coffee - it’s second nature to you.

You may have heard a lot about what it does to your body – its surprising benefits and side effects alike.

But can you really tell which is truth from #fakenews?

Today we’re going to do some myth busting.

Here are 3 things about coffee – and what the real score is.

The holidays are upon us. It’s only October but with the rate this year has gotten to the tail-end, we’ll all be wearing our favorite sweatshirts (forcibly or otherwise) and devouring the holiday away in no time.

The forward-looking you will already be starting to watch that *extra holiday weight* before the holiday even starts.

But one step at a time, right? After all, there’s a few weeks left before the celebrations and holiday parties officially kick in.

If the java lover in you has ever been curious whether caffeine can help curb the appetite, now is the perfect time to find some answers.

The word on the street is that caffeine is one of the best appetite suppressants.

Spoiler alert: researches tell us the jury’s still out on this one. 

For us coffee junkies, coffee is a staple part of our day.

Without it, we’re essentially a zombie rolling out of bed.

One cup is all it takes to bring us to life. And there’s nothing better than an aromatic smell of freshly brewed coffee right?

Unfortunately, sometimes this aromatic smell comes with a not-so-pleasant odor.

Coffee breath is the bane of the otherwise epic experience of enjoying your daily cup of joe.

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. [1] 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.

Adverse effects include reduced absorption [2, 3], heightened side effects, and prolonging the drug's stay in your system.

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. [4] 

Achieving a healthy disposition and well-being can be as simple as keeping yourself hydrated.

Can’t put two and two together?

Studies show that poor hydration leads to poor health. 

So what does this mean for coffee-lovers and caffeine junkies?

Some people say that caffeine can make you dehydrated.

But is there any truth to this? Or is it just another #fakenews alert?

About 90 percent of Americans consume caffeine in one product or another.

Does caffeine really stunt growth? Or is it a mere urban legend? Here are some reasons why this may NOT necessarily be gospel truth, plus some evidence-based studies bringing us good news that caffeine does not hamper growth.

Caffeine appears to raise blood pressure, in some people in the short term and in others in the long term. This is an important question because 80 percent of Americans drink coffee every day and about 90 percent of people worldwide consume caffeine in one product or another.

It's also an important question because high blood pressure can cause strokes or heart attacks.

Ever wondered how to get the best bang for the cup? Of coffee at least.

What if I tell you that the best way you can stay awake after drinking coffee is to get some shut-eye?

Ironic as it sounds, it's how you can recharge and make the most out of your tall cup of cappuccino, or a shot of espresso.

In fact, coffee naps are a thing. If you take caffeine before you snooze in the afternoon or whenever, when you wake up you'll feel less groggy, experts say.

The effect comes by getting the benefit of the sleep, add to that the stimulating benefits of caffeine when you wake up. Both caffeine and sleep alleviate tiredness, so the double whammy works well together.

Much of what we know about coffee are its benefits: it perks us up, gives that much-needed boost during an afternoon slump, makes us do better in sports, helps us focus, makes our skin glow, speeds up our metabolism, and essentially gets us in a better mood!

But perhaps the magnitude of coffee’s benefits all boil down to what many coffee lovers and researchers believe:

Coffee drinkers live longer.

But is there scientific evidence behind this claim? This article will find out!

How many cups of coffee do you normally have in a day? 

Two? Three? Four? More?

If you’ve read one of our articles “Here’s how much caffeine you can have in a day,” you will know that the sweet spot is 400 mg a day. That’s equivalent to 4 cups of brewed coffee.

This is the ultimate good news for coffee-lovers, right?

But what if you go beyond four cups of joe a day? What exactly will happen?
