Caffeine is without a doubt the greatest natural stimulant ever discovered.

In 2017 global coffee sales topped 21 billion pounds.

That's 3 pounds of coffee for every man, woman, and child on earth.

When you consider most of the world had never heard of coffee until a few hundred years ago that's a pretty remarkable statistic.

Still, there are plenty of people who either don't like the taste of coffee or simply don't have the time or opportunity to make or buy a cup of coffee when they really need a pick me up.

Fortunately today these folks have caffeine pills. And below are the 7 best caffeine pills on the market.

1. ​​​​Editor's Choice: Time Release Caffeine

If there’s a downside to most caffeine pills, it's that the energy boost they provide is short lived. Not Time Release Caffeine Pills, however.

They are designed to be absorbed slowly so that the caffeine is released over most of the day.

This way you avoid the sometimes hard to take jolt and have a more natural-feeling elevation in your energy levels that ramps up slowly and dissipates slowly at the end of the day.

Time Release Caffeine tablets provide a total of 100mg of caffeine with no gluten, no soy, no nuts, banned substances or anything else you don’t want.

3. Genius Caffeine Extended Release 

Genius Caffeine Extended Release is marketed as the only time release caffeine pill on the market.

The microencapsulated design of Genius Caffeine is effective in spreading out the caffeine hit which helps prevent jitters and rushes.

What to Look For in a Caffeine Pill

  • ​Caffeine content - The average healthy adult will want anywhere from 100 to 200 mg of caffeine in their caffeine capsules. Any more may lead to jitters and trouble getting to sleep. Any less is not likely to produce the type of jolt you’re after. (1)
  • ​Value/price - With a cup of coffee at Starbucks costing upwards of $5 caffeine pills are a far better value proposition. Of course, with caffeine pills, you don't get to enjoy the bland corporate furniture and soulless atmosphere of SBs, but you do get the pick me up you need. And over the course of a week, you'll save enough for a nice dinner.
  • ​Other ingredients - You buy caffeine tablets for caffeine, not vitamin C. Some manufacturers though pad their caffeine pills with fillers to make them appeal to a wider audience. Whether you appreciate a lot of extras in your caffeine pills is up to you.

Caffeine Pills vs. Coffee

caffeine pill vs coffee
  • ​With a cup of coffee or espresso, it can be darn near impossible to determine just what kind of caffeine jolt you're getting until your pupils are pegged, and you're ready to climb a rock wall using only your fingernails. With caffeine pills, you know exactly how much caffeine you're getting.
  • ​Many people do not like the taste of coffee no matter how you dress it up and so they don’t get to enjoy caffeine’s many benefits. Caffeine pills alleviate this problem and allow those not enamored of coffee to still enjoy a caffeine boost.
  • ​Often times getting a cup of coffee when you hit the afternoon energy wall can be nearly impossible. With caffeine pills, however, you simply take one and get back to work without skipping a beat.
  • ​Even if you can drum up a cup of coffee in the afternoon chances are it will only provide a fraction of the energy boost you’ll get from caffeine pills. And it will take longer to kick in.
  • ​ Regular coffee drinkers also tend to suffer from yellow teeth. There is no such embarrassing development with caffeine pills. (2)

Benefits of Caffeine Tablets

  • Quick energy boost - As we have seen caffeine capsules will provide you with a quicker, sometimes more substantial jolt of energy than you’ll usually get from a cup of coffee. While there’s plenty to be said for the ritual of preparing and drinking coffee, sometimes you just don’t have time for the ritual.
  • ​Sharper mental focus - There’s little doubt that as the caffeine from your caffeine pill begins to increase your metabolism more blood will be pumping through your veins into your brain where it will deliver more oxygen and provide a higher level of focus and awareness.

  • ​Enhanced athletic performance - Few are the people who workout without first either drinking a strong cup of coffee or taking caffeine tablets. The boost you get from a caffeine pill can make the difference between achieving your physical fitness goals and coming up short. (3)

​Are There Any Side Effects?

When taken as directed, caffeine pills are as safe as any other supplement. Keep in mind though that any supplement, when taken to excess, is bound to generate side effects and caffeine is no exception.

As such, side effects should they occur typically take the form of insomnia, headaches, rapid heart rate, irritability, jitters and possibly gastric distress or acid reflux.

As we said, however, most of these can be avoided by using caffeine pills as directed.


1. Can you chew caffeine pills?

None of the best caffeine pills on the market actually come in chewable form. Furthermore, trying to chew a standard caffeine pill is likely to produce an extremely unpleasant taste experience.

2. How long will caffeine stay in my system?

The exact amount will depend on how much you took. If you stick to the script and take only as directed, the caffeine should clear your system in 4 or 5 hours. If you overdid it, you could be in for a long sleepless night.

3. Can caffeine pills be used for weight loss?

The best caffeine supplements can and often are used to help in weight loss efforts. However, their use needs to be augmented with exercise and proper diet.

4. Can you take these before going to bed?

Not if you want to sleep. It is recommended you don't take any caffeine pills within 6 hours of your planned sleep time. So if you typically turn in at midnight, don't take any caffeine pills after 6 pm.

5. Can you overdose on caffeine tablets?

While it is theoretically possible to overdose on caffeine, the amount you would have to consume makes it extremely unlikely it would ever happen. Scientists estimate you would need to consume something like 5000mg in a day to overdose.
