If you find yourself trying coffee and lemon drinks, energy drinks, and anything else under the sun that promises to keep you awake, caffeine pills may be just what you’re looking for.

After all, caffeine is the world’s most consumed drug,[1] but mostly everyone gets it from coffee or sugary sodas. 

The problem with that is mostly everyone adds tons of dairy and sugar to their coffee, which is known to be inflammatory[2] and contributes to a diverse array of inflammatory-related health problems. Plus, the sugar in soda and the high amount of caffeine in energy drinks also cause jitteriness, anxiety,[3] and a pretty hard crash of fatigue once it wears off. 

We’ll look at the best caffeine pills on the market to boost energy and concentration while improving physical performance. Whether you’re a busy student or a professional looking to stay alert and focused, these supplements might be just what you need.

What Does Caffeine Do?

Caffeine[3] is a natural stimulant that blocks the effects of adenosine,[4] a central nervous system neurotransmitter that makes you feel sleepy. This can increase the activity of other neurotransmitters that aren’t blocked, like dopamine and norepinephrine. These chemicals are known for enhancing mood, alertness, and cognitive function. Another benefit of caffeine is that it can increase your metabolism and fat oxidation, making it easier to work out and lose weight. 

Of course, severe drawbacks affect a large portion of the population. These include immediate side effects of caffeine overdose, like jitters and anxiety. And, remember, synthetic caffeine made in a lab[5] is often more potent than caffeine that comes from plants.

It can also create insomnia and lead to worsened anxiety symptoms in the long term. Plus, if you’re already suffering from an anxiety disorder or simply feeling more stressed, caffeine can exacerbate symptoms[6] and worsen things.

5 Best Caffeine Pills To Boost Energy & Studying In AU 2023

If you have difficulty keeping up with the demands of daily work or school life, caffeine might just be what you need. Of course, a healthy lifestyle with plenty of sleep is best, but if you need a little extra pick-me-up for days when rest just isn’t possible, these caffeine pills might help:

Performance Lab Caffeine+

Performance Lab’s high-quality caffeine supplement with B vitamins, pure caffeine, and L-theanine, an amino acid found in green tea, gives a natural and balanced energy boost.

  • Natural caffeine from organic coffee beans. 
  • Contains an energy-boosting B vitamin complex. 
  • Includes the amino acid L-theanine. 
  • Vegan, free from artificial additives and allergens.
  • Third-party lab tested.
  • Might not be strong enough for people with a high caffeine tolerance.

Performance Lab Caffeine+ contains 50 milligrams of pure caffeine per capsule, sourced from organic coffee beans. It also has 100 mg of L-theanine, which improves cognitive function. 

L-theanine is an amino acid often used for anxiety, stress,[7] and insomnia. Combining the two together might give a more balanced and focused energy boost, making it a great choice for people who easily get overstimulated or anxious on caffeine. 

The Performance Lab Caffeine+ supplement also has several B vitamins that can improve levels of serotonin, dopamine, and norepinephrine. These neurotransmitters can improve mood and cognitive function,[8] so it doesn’t need such a high caffeine dosage. 

It’s also vegan and free from synthetic additives, preservatives, and allergens, making it the best choice for people with dietary restrictions or allergies. All of Performance Lab’s products are also third-party lab tested, making it a safe option. 

While the lower dosage of caffeine might not be enough for people with a high tolerance, you can take up to five pills per day to get the amount you need. And when it comes to caffeine pills, it’s always better to start slowly to avoid scary side effects like heart palpitations, shortness of breath, jitters, and panic attack symptoms. That’s what makes this pill great — you can likely avoid those negative side effects.

Elm and Rye Caffeine

Elm and Rye offer a natural source of caffeine that can provide a clean and sustained energy boost, but it doesn’t contain any other ingredients to support cognition or mood.

  • Natural caffeine from green coffee beans.
  • Affordable option with 120 capsules.
  • Third-party lab tested for purity with lab results available online.
  • Might not be strong enough for people with a high caffeine tolerance.
  • Might cause jitters, insomnia, or anxiety for those with a low tolerance.

Elm and Rye Caffeine is derived from green coffee beans, making it a natural and sustainable energy source. The product contains 100 mg of caffeine per capsule, which is the amount of caffeine in an average cup of coffee. This dosage is great for people who want to customize their caffeine intake and avoid overdose side effects. 

Each bottle has 120 capsules, making it a good value for money. But, if you have a high caffeine tolerance, you might need more than one capsule daily. 

Since it has no other ingredients besides pure caffeine powder, it might also cause some mild side effects for people with a low tolerance, like jitters, heart palpitations, or insomnia. 

It’s also third-party lab tested for caffeine content and microbial contamination, with its results available online, letting you know you’re getting a high-quality product that you don’t have to worry about. 

Overall, Elm and Rye Caffeine is a natural and affordable source of caffeine that can give you the energy boost you need.

Life Extension Lightly Caffeinated Mega Green Tea Extract

A natural and healthy source of caffeine for a gentle and sustained energy boost. Rich in antioxidants but possibly too low a dosage of caffeine for people with a high tolerance.

  • Natural source of caffeine from green tea extract.
  • High levels of EGCG, a potent antioxidant.
  • Low dose of 25 mg caffeine per serving.
  • Might not be enough caffeine for people with a high tolerance.

Life Extension Lightly Caffeinated Mega Green Tea Extract is derived from green tea extract. It has 25 mg of caffeine per capsule, which is a low dose compared to other caffeine tablets. But, this low dosage is great for people who are sensitive to caffeine or want to avoid the negative side effects of higher doses.

The green tea extract is also rich in polyphenols and antioxidants with high levels of epigallocatechin gallate,[9] or EGCG. EGCG is a plant-based compound categorized as a polyphenol that might help to reduce inflammation,[10] aid weight loss, improve brain function, and prevent heart and brain disease. Because of green tea’s weight loss benefits, it might be one of the best caffeine pills for weight loss. 

Overall, Life Extension Lightly Caffeinated Mega Green Tea Extract offers a natural source of caffeine along with additional health benefits. While the low caffeine content may not suit everyone, the green tea extract can boost energy and support overall health.

Eu Natural ELITE Caffeine L-Theanine

Eu Natural ELITE offers a balanced and smooth energy boost, thanks to the combination of caffeine and L-theanine. It’s a good choice for a natural energy boost without crashing.

  • Combination of caffeine and L-theanine for a smooth energy boost. 
  • Free from artificial additives and fillers. 
  • Cheaper option than most caffeine pills. 
  • Third-party lab tested.
  • Capsules might be difficult to swallow.

Eu Natural ELITE Caffeine L-theanine combines 100 mg of caffeine with 200 mg of L-theanine,[7] an amino acid that improves mental focus and reduces anxiety. This combination offers a balanced and smooth energy boost without the jitters or crashes of other caffeine capsules. It might even help keep your energy boosted and your mind alert for a sustained amount of time, compared to taking caffeine alone. 

It’s also a great choice for people wanting an all-natural and high-quality supplement since it’s free from artificial additives, fillers, and allergens. They use a Food and Drug Administration-registered facility with clinically proven ingredients and blend the product in the USA. It’s also third-party lab tested to be effective and bioavailable. 

Finally, Eu Natural ELITE Caffeine L-theanine is one of the cheaper options available, with a 90-day guarantee to try it risk-free. Even though 100 mg of caffeine might not be a lot for those with a high tolerance, adding L-theanine should help give an added effect for studying and concentration.


BulkSupplements Caffeine Pills offer a simple and affordable way to increase caffeine intake, but the high dose and lack of additional ingredients may not suit everyone’s needs.

  • High dose of 200 mg caffeine.
  • Free from additives and fillers.
  • Third-party lab tested.
  • Affordable option.
  • The high dose isn’t suitable for caffeine-sensitive people.
  • Lack of supportive ingredients like L-theanine and B vitamins.

BulkSupplements Caffeine Pills provide a high dose of 200 mg of caffeine per serving without any additives, fillers, or other ingredients. It’s a straightforward option for people who just want a quick hit of caffeine. 

The high dose of caffeine might make it one of the best caffeine pills to stay awake. But, it isn’t great for people with a low caffeine tolerance. The high dosage also makes it more likely to get negative side effects like jitters, anxiety, and shortness of breath. Without added ingredients like L-theanine or B vitamins, you only rely on caffeine to improve your cognitive function. 

Ultimately, it’s one of the cheaper options but not necessarily the most well-rounded product. The fact that it’s third-party lab tested, however, at least lets you know you’re getting quality caffeine without any additives. They also use a National Sanitation Foundation-certified & FDA-registered cGMP manufacturing and distribution facility to make their products.

How To Take Caffeine Supplements

Taking caffeine supplements comes with some risks, so be sure to follow these steps to avoid the common negative side effects: 

  • Consult with a healthcare provider before taking caffeine supplements, especially if you have any medical conditions or take any medications.
  • Read and follow the dosage instructions on the label carefully.
  • Start with a lower dose, even lower than they suggest if you’re sensitive to caffeine, and gradually increase as needed.
  • Take them with food to help prevent stomach discomfort, nausea, and other negative effects like jitters and anxiety.
  • Always drink plenty of water when taking caffeine supplements to stay hydrated.
  • Monitor how caffeine affects your body and adjust the dosage accordingly.
  • Avoid taking them late in the day to avoid interfering with sleep quality.
  • Be aware of potential side effects such as increased heart rate, shortness of breath, and high blood pressure.  
  • Avoid mixing caffeine pills with alcohol or other medications.

If you follow these steps, you’ll be much more likely to enjoy the benefits of caffeine without negative side effects.

Are Caffeine Pills Healthy For You?

Caffeine pills can help improve focus, energy, and alertness. However, like any supplement or medication, you must use them responsibly and in moderation.

While caffeine is generally considered safe in moderate doses, excessive intake has many possible negative side effects,[11] including: 

  • Headaches.
  • Dehydration.
  • High blood pressure.
  • Increased heart rate.
  • Anxiety or nervousness.
  • Jitteriness or restlessness.
  • Insomnia or difficulty sleeping.
  • Stomach discomfort or nausea.

On top of that, many caffeine supplements have additives, fillers, or allergens that can harm some people. Before taking them, it’s best to talk to your doctor and get a full check-up to be sure your body can handle them. 

Also, if you’re already suffering from an anxiety disorder, such as panic disorder[6] or generalized anxiety disorder, it’s better to avoid caffeine pills since they’re more likely to increase anxiety. If you don’t have a disorder but are sensitive to caffeine, you could check out a slightly more relaxing option that still gives an energy boost, like drinking coffee from CBD coffee, which is simply coffee with CBD added.

Benefits Of Caffeine Pills

If you’re not too sensitive to caffeine, or if you slowly build up your tolerance, you can enjoy many of the positive effects,[12] such as:  

  • Increased energy levels.
  • Convenient for on-the-go use.
  • Reduced fatigue and drowsiness.
  • Might improve memory and energy
  • Improved mental alertness and focus.
  • Can act as a mild appetite suppressant.
  • Enhanced athletic performance and endurance.
  • Increased metabolism and potential weight loss support.
  • May provide temporary relief for migraines and headaches.
  • Possible cognitive benefits, such as improved learning abilities. 
  • May reduce the risk of stroke.[13]
  • May reduce the risk of diabetes, stroke, Parkinson’s disease, and heart failure. 

Of course, not all of these benefits[13] will apply to everyone. We all respond to caffeine differently, even depending on the day. If we’re more stressed, haven’t eaten well, or are dehydrated, we may get some negative rather than just positive effects.

What To Look For In Best Energy Pills Over The Counter

Here are some things to look out for when choosing the best caffeine supplement for you:

  • Ingredients: Look for safe and effective ingredients, like caffeine, B vitamins, and adaptogens or nootropics.
  • Dosage: Make sure to start slow with the lowest possible dosage. Even if you have a high tolerance to caffeine, it’s better to start slow and only take more after waiting an hour or so to observe its effects. 
  • Quality: Choose reputable brands that prioritize quality and safety, and look for third-party tested products.
  • Form: Think about if you prefer pills, capsules, or a powder form of the supplement.
  • Price: Consider the price and value of the supplement, but don’t compromise on quality for a lower price.
  • Reviews: Read reviews from other customers to understand their experiences with the supplement.
  • Purpose: Consider why you want the supplement, such as for energy, focus, or workout performance, and choose one that aligns with your goals.

The Bottom Line

Caffeine supplements can be an easy way to boost your attention, alertness, and focus. However, many people are sensitive to caffeine, which can easily cause negative side effects when taken in high doses. Most people experience symptoms like anxiety, jitteriness, upset stomach, headaches, and insomnia. 

Thankfully, the caffeine supplement market is becoming more aware of the importance of low-dose capsules. That’s why many now include ingredients like L-theanine and B vitamins. With these additions, you can get an extra energy boost and focus without worrying as much about the negative side effects. Of course, you should still wait at least an hour after taking a caffeine pill to observe its effects, take them with food and water, and avoid them late in the day. 

Also, make sure you get a full check-up and talk to your doctor before taking caffeine supplements. You can never be a hundred percent certain as to how it will affect you, especially if you have a history of health conditions. For example, people with anxiety or high blood pressure should avoid them. 

Finally, of these top five supplements, Performance Lab Caffeine+ stands out as the best caffeine pill for its clean formula, low caffeine dose, and high amounts of L-theanine and B vitamins. Life Extension Lightly Caffeinated Mega Green Tea Extract offers the added benefits of green tea extract, and Eu Natural ELITE Caffeine L-Theanine also combines caffeine with L-theanine for a more balanced effect. Elm and Rye and BulkSupplements are pure caffeine capsules and might offer the more cost-effective option.
