Considered as supplements, this is your caffeine fix taken in capsule form. It may have natural caffeine straight from the brewing process, while it 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 the 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.
While caffeine pills are safe for many people, there are certain conditions that need to be considered before taking them. People with the following would need to watch their intake and consult their doctor prior to trying caffeine pills: 
hypertension or high blood pressure
heart disease or a rapid heartbeat
gastroesophageal reflux disease (GERD)
Children, adolescents, pregnant and those trying to get pregnant should also think twice about taking caffeine pills. If in doubt, it’s best to check with medical professionals before taking a pill.
Are caffeine pills safe?
A small pill would typically have 100-200 mg of caffeine.
100-200 mg of caffeine sounds reasonable, given that a cup of your favourite caffeine fix could range from 75-400 mg a cup!
However, if your caffeine intake is little to moderate or you’re not a regular coffee drinker, then you may want to go easy on caffeine pills. Especially if you don’t want to experience the pesky side effects of over-caffeination - jitters, anxiety, restlessness.
Viter Energy, however, has 40 mg of caffeine per mint, and is perfect if you want to take it easy on your caffeine intake while still having that extra kick in your morning (or throughout the day)!
Essentially, daily caffeine consumption can go as high as 400 mg. However, note that this is the max. So if you plan to chew on more than one caffeine pill, you need to watch out for the other things you eat, as they may also contain caffeine. As the amount of caffeine may vary from one product and brand to another, be sure to check the package or use an onlinecaffeine calculator.
Coffee vs caffeine pill: pros and cons
Caffeine pills have sparked a debate. Which one is the best form of caffeine fix - a daily cup of Joe or these tiny but mighty pills?
Here are some of the more interesting pros and cons on this whole caffeine dialogue:
Why caffeine pills over coffee
Taste and calories.Some people prefer caffeine pills because they don’t like how coffee tastes. If it doesn’t come with the usual bells and whistles - cream, sugar and other add-ins - then it doesn’t do it for them. They would then go for the caffeine pills, which could give them a caffeine jolt without the added calories. Find out how many calories are in your coffee add-ins here.
Less acidity. Some people prefer caffeine pills because they don’t get acid reflux from it. Coffee - especially black - may lead to an acidic tummy because of the acidic substances found in coffee beans.
Less cholesterol.Coffee has coffee oils like cafestol and kahweol, which may lead to higher cholesterol levels for some, especially for those who prefer boiled brews and espressos. Caffeine pills just don’t have these oils and don’t have the same effects.
Fewer trips to the bathroom. Caffeine is a diuretic. So while both coffee and caffeine pills can make you pee more, having caffeine in pill form instead of liquid can help reduce your trips to the bathroom.
Why coffee over caffeine pills
Having coffee is more than just having coffee. It’s an experience. Your everyday trip to the nearest barista before work could be an integral part of your morning routine. Or catching up with friends (or a first date) over coffee is in itself an experience that a single caffeine pill can’t replace.
It’s harder to overdo your caffeine intake with a cup or two of coffee. With caffeine pills, enjoying the benefits in such a short time can make you pop more and lose count of your daily caffeine intake, leading to caffeine overdose.
Caffeine Pill Addiction
While caffeine dependency is very common (just ask your colleague who travels to Starbucks twice/thrice a day), caffeine pills aren’t classified as addictive. This is according to the Palo Alto Medical Foundation, which reported that unlike heroin, cocaine and other street drugs, caffeine pills don’t lead to addiction. 
However, because of the stimulating effects of caffeine in general, caffeine pills could be habit-forming. Hence, there are warning labels found on the packaging and displays of caffeine pill brands.
Erectile dysfunction. In combination, those are two of the ugliest words known to man. But can caffeine help you get it up?
Science hasn't found the definitive answer to this question, but one study concluded that fewer men who consume caffeine have problems performing. The study said:
Caffeine intake reduced the odds of prevalent ED, especially an intake equivalent to approximately 2-3 daily cups of coffee (170-375 mg/day). This reduction was also observed among overweight/obese and hypertensive, but not among diabetic men. Yet, these associations are warranted to be investigated in prospective studies
