Are Caffeine Pills Safer Than Energy Drinks? – Full Research

Caffeine pills and energy drinks are both popular sources of energy, but which option is safer?

Caffeine in high doses can cause anxiety and jitters, and energy drinks usually get a bad rep, so, there’s definitely something to be explored here.

So, that’s what we’ll do. 

In this article, we’ll compare the two and find out, once and for all, are caffeine pills safer than energy drinks.

How Do Caffeine Pills and Energy Drinks Compare?

Comparing the two might seem easy, but considering they differ in various aspects, such as caffeine content, added ingredients, and nutritional value – there’s a lot of ground to cover here.

Typically, a caffeine pill contains around 100 to 200 mg of caffeine, providing a concentrated dose of the stimulant without any additional calories or additives. 

This alone makes them a very, very attractive option for those who desire a pure caffeine boost without unwanted extras.

On the other hand, energy drinks vary widely in their caffeine content, ranging from 50 to 300 mg per serving, so you have to examine the label to find out what you’re getting.

But the bigger issue here is that energy drinks often include additional ingredients such as taurine, certain vitamins, electrolytes, acids, and herbal extracts that are marketed as contributing to increased energy and focus. 

However, the effectiveness and sometimes safety of some of these ingredients are frequently debated. 

Also, individual reactions to these ingredients vary a lot, so there’s that, too.

In addition to these additives, energy drinks usually contain ungodly amounts of sugar and calories

Now, that’s not necessarily bad, because despite what you might hear or read, there’s really no such thing as “bad calories”.

That said, a standard 16-ounce energy drink can pack anywhere from 200 to 800 calories, with sugar content reaching up to 60 grams or more.

That’s excessive, to say the least. [1]

This much sugar can lead to undesirable effects, such as blood sugar spikes and crashes, contributing to feelings of fatigue and sluggishness. Long term, it could lead to more severe complications, such as diabetes or cardiovascular disease.

To combat that, some energy drinks come in sugar-free versions, which replace sugar with artificial sweeteners like aspartame. 

While these options reduce calorie and sugar intake (some of these are 0-calorie 0-sugar drinks), they still contain the various other additives found in their regular counterparts, and they often aren’t too keen on your gut microbiota. [2] 

Additionally, the long-term health effects of consuming large amounts of artificial sweeteners are still under investigation, but the research isn’t promising.

Are There Any Dangers Associated with Taking Caffeine Pills?

Generally speaking, taking caffeine pills is considered safe if taken within the recommended daily limits – up to 400mg per day.

On the other hand, there are some potential dangers associated with taking caffeine pills, particularly when consumed in excessive amounts or without proper caution:

  • Overdose: Consuming too much caffeine can lead to an overdose, which can cause symptoms such as rapid or irregular heartbeat, nausea, vomiting, diarrhea, disorientation, and seizures. In severe cases, a caffeine overdose can even be fatal.
  • Increased heart rate and blood pressure: Caffeine is a powerful stimulant that can increase heart rate and blood pressure. Those with pre-existing heart conditions or high blood pressure should probably stay away from caffeine pills as they can exacerbate these issues and increase the risk of cardiovascular events.
  • Sleep disturbances: Excessive caffeine intake can lead to insomnia, restlessness, and difficulty falling or staying asleep. Taking them too close to bedtime or consuming high doses will probably negatively impact sleep quality and duration.
  • Anxiety and irritability: Caffeine can cause or worsen anxiety and irritability in some individuals, particularly when consumed in high doses. People prone to anxiety or panic attacks should exercise caution when using caffeine pills.
  • Dependence and withdrawal: Regular consumption of caffeine can lead to physical dependence, resulting in withdrawal symptoms when discontinued. While not severe, withdrawal symptoms can include headaches, fatigue, irritability, and difficulty concentrating.
  • Interactions with medications: Caffeine can interact with certain medications, altering their effectiveness or increasing the risk of side effects, so consult with your doctor if you’re on any medication.

Is it Safe to Take Caffeine Pills Every Day Long-Term?

Yes, caffeine pills can be safe for long-term use when taken in moderation. 

As long as you’re a healthy individual and you’re mindful of your total caffeine intake from all sources, and you listen to your body – long-term usage of caffeine pills shouldn’t cause any issues.

What’s a Safe Dosage of Caffeine Pills to Take?

A safe dosage of caffeine pills for a healthy, average adult shouldn’t surpass 400mg.

However, it’s probably best if you divide your caffeine intake into several smaller doses throughout the day and do not take 400mg all at once.

50-200mg of caffeine should be more than tolerable for most healthy adults.

Are There Dangers Associated with Energy Drinks?

Energy drinks can pose risks, especially when consumed in excess or by vulnerable populations, such as children, pregnant women, and individuals with pre-existing medical conditions. 

Some potential dangers associated with energy drinks include:

  • Excessive caffeine intake may lead to side effects like jitters, anxiety, and insomnia
  • High sugar content, which can contribute to weight gain, dental issues, and increased risk of chronic diseases
  • Interactions between added ingredients, such as herbal extracts or artificial sweeteners. may cause adverse effects or interact with medications

Is it Safe to Drink Energy Drinks Daily Long-Term?

While it is not healthy to drink energy drinks daily for a long period of time, it is also not necessarily unsafe to drink energy drinks daily long-term.

It is definitely not something anyone would recommend you do, but as long as you’re mindful of your total calorie, sugar, or caffeine intake, a daily energy drink shouldn’t be too much of an issue long term.

That said, complications could definitely arise if you don’t choose your drinks wisely and if you don’t mind the rest of your diet, so if you want to err on the side of caution (which you should), you probably shouldn’t drink energy drinks every single day. [3]

Is it Safe to Take Caffeine Pills Pre-Workout?

As long as you don’t overdo it with a dose, taking caffeine pills, pre-workout is more than safe.

A 100 or 200mg dose of caffeine before a workout yields plenty of performance benefits and is generally well tolerated by most people.

And, even if you can’t handle these doses, you might as well take a smaller dose and see if that works for you.

Is it Safe to Drink an Energy Drink Pre-Workout?

It is generally considered safe to drink an energy drink pre-workout.

The caffeine and calorie content of an energy drink can provide you with a relatively healthy boost of energy before working out.

Also, if the energy drink is well-formulated and it contains well-dosed electrolytes, vitamins, and other essential nutrients – even better.

Bottom Line: Are Caffeine Pills Safer Than Energy Drinks?

Yes, all things considered, caffeine pills are safer than energy drinks.

There are far fewer side effects associated with caffeine pills than with energy drinks due to their standardized caffeine content and lack of added sugars, calories, and other ingredients that may pose additional risks.


Between the two, caffeine pills are a much better option – across the board.

They’re healthier, safer, cheaper, and more convenient.

The only thing energy drinks have going for them is the taste, but we don’t really think that should ever be a deciding factor.
