Reviewing the Best Caffeine Supplements
When you need a bit of a pick-me-up, caffeine is definitely something that you can take advantage of. It is certainly one of the most reliable chemicals out there that are super effective at giving you that boost you need to make it through the day.
It turns out that caffeine actually has way more benefits than what we use it for. Not only can it give you a bit of energy when you need it most, but it can also help your mind stay sharp and even increase your endurance and strength.
One of the best ways to get extra caffeine when you need it is by taking caffeine pills. They offer an exact dose of caffeine without additional ingredients that can be a hindrance to deal with.
The problem with caffeine pills is that there are so many of them out there. In general, the amount of caffeine-related products, besides coffee, of course, is pretty staggering. Deciding which one of these products you should use can be pretty difficult. Fortunately, we are here to help you with this problem. Here is our list of the best caffeine pills of 2017. Remember that this list isn’t compiled in any specific order.
Top 10 Best Caffeine Pills in 2023
On the hunt for the best caffeine pills? Take a look at the top-rated caffeine pills along with a list of the pros and cons on what to be aware of before buying them in a store or online.
If you are looking for a product that has very few ingredients in it and focuses mostly on caffeine, then Nutricost Caffeine is definitely a good choice. This caffeine pill offers 200 mg of caffeine per single pill with only two additional ingredients added in, which are rice flour and gelatin.
Fewer additional ingredients mean that your body doesn’t have to deal with additional stuff and caffeine can be at the center of the stage. The problem with one of the ingredients, gelatin, is that it’s actually an animal product, which means that vegetarians and vegans can’t take advantage of this product.
Most companies that boast about their product through the product name are usually just trying to get some attention. This isn’t the case with Genius Caffeine; they actually were pretty clever with their formula. There are a few different ways to introduce caffeine into the system, and most of these methods are quick acting. However, Genius Caffeine decided to focus on releasing caffeine slowly into your body, which holds quite a few benefits.
Essentially, this formula is able to slowly deliver the caffeine into your bloodstream, which means that your boost time is less drastic and much smoother. The end result is a longer duration of the energy boost and none of the side effects of the well-known crash effect.
SmarterVitamins Caffeine + L-Theanine
When it comes to caffeine and its effects on the body alongside other supplements, there are many opportunities to improve the benefits you get from the possible combinations. SmarterVitamins decided to try and get extra benefits from combining multiple ingredients.
Their clever choice of additional ingredients was in the form of L-theanine. Research shows that L-theanine, which is found in green tea, has many synergetic properties that match very well with caffeine. The product itself contains about 200 mg of caffeine per pill, which is a pretty significant amount that should deliver the boost you are seeking.
Additionally, L-theanine is also known for pacifying some of the side effects which are associated with caffeine products. Things like jitters or nausea are often associated with caffeine products, but luckily, L-theanine is able to successfully counteract these effects.
Jet Alert Caffeine
Sometimes 200 mg of caffeine is a bit too much. There are certain circumstances during which you might just need a little bit of a pick me up, like after a plane flight. Jet Alert Caffeine has you covered; their capsules contain a more precise dose of caffeine at 100 mg each.
One of their primary reasons for reducing the dosage to make it more precise is that there is quite a bit of research being done about caffeine and its effects on your body. It has been verified that the effects of caffeine are proportional to your body mass, so while 200 mg is a good number, if you are looking to gain more out of each milligram of caffeine, then taking the more precise 100 mg is a better option.
Best Naturals Caffeine
Remember when we said that with caffeine supplements fewer ingredients is actually more? Well, Best Naturals Caffeine didn’t think so. They decided to add quite a bit of other ingredients alongside their solid 200 mg of caffeine tablets.
For example, one of their added ingredients is 75 mg of calcium. We aren’t entirely sure why they decided to add calcium to their supplement, and we know that usually, extra ingredients can hinder the effects of caffeine. I guess Best Naturals Caffeine didn’t get the memo.
Zhou Energy + Focus
Yet again, L-theanine is being used alongside caffeine in another product. We know that both of these synergize well, and so do the makers of Zhou Energy + Focus. These guys did their research and know well enough that caffeine by itself can cause some unwanted side effects, like jitters or nausea. So they added L-theanine to counter those side effects and improve the positive effects of caffeine overall.
They even took their formula a bit further by using the well-known and vegan-friendly cellulose for their capsule. There is another ingredient added into the mix and its rice flour. Its main function is pretty simple in this supplement. It’s just filler, but it’s a harmless one.
Vegetarians and vegans might be somewhat disappointed with this product, but only because BulkSupplements Caffeine decided to use gelatin in their capsules. Otherwise, this is one of the more “straight to the point”, no unnecessary ingredients supplements. Besides the previously mentioned gelatin, the only ingredient found in this supplement is caffeine, and it includes a good 200 mg of it.
So if you are more of a purist and are trying to avoid those potentially problem-inducing ingredients that you might have allergies to, then BulkSupplements Caffeine is a pretty good choice for you.
Vitalfuse Fused Focus
While this supplement is more about the sum of its ingredients rather than just about caffeine, we aren’t sure how effective it is when all those ingredients are put to the test. The company claims that their product is designed to give you everything you need for maximum focus and to boost the effects of caffeine to the max, but in reality, the only way to check this product’s effectiveness is by trying it on your own.
Among some of the ingredients listed in Vitalfuse Fused Focus, we can find theacrine, bacopa, and other nootropic supplements which are supposed to sharpen your mind. The research about how beneficial these nootropics are is still limited, but if you want to give it a shot and are looking for a bit more than the rush you get from caffeine products, then Vitalfuse Fused Focus is a good choice. In terms of actual caffeine dosage, their capsules contain 150 mg of caffeine, which does give you more control over the dosage.
ProLab Caffeine Maximum Potency
Maximum is a word which is frequently used in the supplement world. Sometimes it’s misleading, but luckily in the case of ProLab Caffeine Maximum Potency, it’s not. This supplement delivers exactly what the name suggests, 200 mg of caffeine without any other ingredients except some common binders.
This product is for those who need that power up right now and don’t have time to wait for a slow-releasing formula to take effect. You get less control with the dosage, but it shouldn’t be a problem for those who really need that boost.
Vali Time Release Caffeine
We think of this specific product as more of a sensitive supplement. It contains a small amount of caffeine per capsule, only 100 mg, and it also uses the slow time-release formula which doesn’t give the caffeine an opportunity to hit you all at once.
Those of you who get sick after taking caffeine supplements that release quickly will definitely benefit from Vali Time Release Caffeine. Otherwise, this might just be too little of a dose to get you what you need if you are looking for that extra energy quickly.
Caffeine Supplement Side Effects, Dosage, And Benefits
Caffeine has been used for many ages and its effects on the human body have been pretty carefully documented. The types of supplements that focus on caffeine are the ones you would take to get stuff done quickly or if you need that extra boost when you are slowing down. Whether it’s studying longer, lifting higher amounts of weight, or running faster, caffeine is definitely capable of helping you get that extra edge.
Because it has been studied so well, it is easy to find out how much caffeine you need depending on what you are looking to accomplish. Likewise, it’s also relatively easy to figure out when to take it to get the most performance out of a caffeine boost. Keep in mind that there are some side effects associated with caffeine and you should always keep an eye out for these effects so that you can monitor your health accurately.
There are many different benefits that you can take advantage of when using caffeine. Whether it’s your mental or physical performance that you are trying to improve, caffeine can accomplish both. Researchers have concluded that the benefits of caffeine come in a variety of different forms and are able to improve your performance in many different fields.
When talking about resistance training, activities that tire you out quickly, caffeine seems to be capable of suppressing the effects of fatigue. This, in turn, helps you perform for a longer amount of time. So basically, if you are a runner then caffeine would be able to let you run longer without stopping if you lift then caffeine is able to give you the ability to do more reps, and so on.
This was proven by a study that was released in 2007. This study was done on the number of bench presses and leg presses that a group of volunteers could perform while subjected to a single dose of caffeine. This volunteer group was compared to another group that was given placebos and was used as the control group. The caffeine dosed group ended up on average gaining 2.5 reps of bench press over the control group. Both groups reported that they felt the same amount of fatigue at the end of their reps. This means that performance gains are shown across the board.
Similar reports were released in 2009 about 21 different studies that were conducted. The results of these studies were pooled into one block of data and analyzed. The results showed that caffeine is able to increase performance by at least 3 percent and even more. While this percentile might not seem like a big number, consider the increase in the length of a marathon that you can run with this type of boost. This means you would finish the marathon about 1.5 kilometers faster under the influence of caffeine if compared to finishing it without the help of caffeine.
Other exercises can also be improved with the help of caffeine. A good example is anaerobic exercises that involve high-intensity bursts of effort which last a minimum of 60 seconds. This was verified by a study that was done in 2009.
There are exercise types that do not benefit much from caffeine. The well-known HIIT, high-intensity interval training, which usually involves short rests in between repetitions, don’t really utilize the boost effect that caffeine has on our endurance. This is most likely due to the downtime throughout which we are wasting the effects introduced by caffeine and thus the benefits are very limited.
Our mental state is also greatly improved by caffeine. Plenty of research has been done to verify that our mental state, alertness, and even reaction time are all susceptible to being improved by caffeine. However, this is usually reflected by a moderate consumption of caffeine, which means your dosage plays a huge role in how caffeine affects your mind.
One of the greatest benefits of caffeine on our brain is that it makes recalling short pieces of information much easier. Not only that, but it also increases our capacity for storing short amounts of information. The result is an improved studying capability, so things like planning or scheduling become easier, and in general, anything that has to do with work which is cognitively arduous becomes less strenuous.
We mentioned L-theanine in many of the products we listed above. This ingredient is well-synergized with caffeine and has a great impact on the mental benefits you get from caffeine. This synergy was noted when research was done on the power of green tea. Some of the benefits which were concluded seemed to be a result of L-theanine rather than just caffeine. Not only that, but some of the negative effects of caffeine can be controlled thanks to L-theanine. This conclusion was drawn through a 2008 published study that showed results of research done on the combination of L-theanine and caffeine. The study showed that caffeine alone can cause jitters, especially when taken at a higher dosage, but L-theanine is capable of making these jitters completely vanish. This is exceptionally good news for some people who seem to be slightly more sensitive to the effects of caffeine than others.
In addition to L-theanine, there is also a component found in green tea that synergizes extremely well with caffeine, and it is known as EGCG. It has been found that the combination of EGCG and caffeine can effectively increase the results of wither dose significantly more than those that can be achieved with either ingredient alone. This further proves that green tea extract is a great ingredient to find alongside caffeine in any supplements to help boost its effectiveness with not one, but two different components.
One of the more common effects that some people experience after taking caffeine is the tendency to develop jitters. This usually happens among those who are somewhat sensitive to caffeine but can also occur if you take too much caffeine at one time. High dosages of caffeine should be avoided. The general suggestion is to take no more than 400 mg of caffeine per day. If this dose is exceeded, you may start suffering from insomnia, headaches, tremors, restlessness, nausea, and even a faster than normal heartbeat.
Extreme doses of caffeine can result in fatalities. Because of this, we strongly suggest keeping a close eye on the amount of caffeine you are taking through your diet if you are taking caffeine supplements. Keep in mind that other supplements, such as weight loss products, generally use some amount of caffeine in them and this might be plenty of caffeine to meet or exceed the amount that you should be taking throughout the day. This is also true of coffee, soda, and many other regular beverages that you may commonly drink. Additionally, the effects of caffeine usually take a few hours to completely diminish, so don’t stack taking caffeine supplements. Instead, spread them out evenly throughout the day.
The recommended dosage of caffeine varies depending on your body mass. One study which was done on the correct dosage of caffeine determined that per 2.2 lbs. of body mass, you should be taking between 3 mg to 6 mg of caffeine. So if your weight is around 180 lbs. then your optimal dosage is anywhere between 245 mg to 490 mg of caffeine. Determining the exact number shouldn’t be too difficult if you take 100 mg caffeine pills.
The timing of your caffeine intake also matters. It is recommended to take your supplement or caffeine intake between 60 minutes and 90 minutes prior to when you want the peak of your performance to occur. The effects of caffeine last for several hours, so timing it perfectly isn’t as big of a problem as it might seem. If you plan on performing for an extended amount of time, it might be a good idea to invest in a slow-release formula which will deliver caffeine into your system at an interval rate so that the effects of it are more constant and are longer-lasting.
Frequently Asked Questions About Caffeine
Caffeine is a controversial supplement ingredient because of its label as a natural stimulant. Here is an overview of the most popular commonly asked questions about caffeine pill supplementation that users may have.
Q: Are caffeine pills bad for you?
A: Caffeine pills are safe for most people to take, although they can be harmful if taken in high doses. For a definitive answer, we recommend that users consult their primary healthcare provider to ensure that caffeine pills are right for them. Caffeine can be harmful to consumers with anxiety or panic disorder.
Q: Do caffeine pills actually work?
A: Yes, caffeine pills should work as advertised. Each pill contains pure caffeine, and your body absorbs this caffeine just like it would absorb caffeine in coffee or tea. The effects of caffeine are well-documented in the scientific community, although a number of consumers might experience anxiety or other negative effects from the use of caffeine.
Q: Are caffeine pills better than energy drinks?
A: Caffeine pills provide pure caffeine, while energy drinks mix caffeine with sugar, herbal extracts, and other stimulants. If you simply want caffeine, then caffeine pills may be better than energy drinks, especially considering the concentration of the desired chemical in these pills.
Q: How long do caffeine pills take to kick in?
A: The central nervous system, including the brain, will feel the impact of caffeine shortly after consumption. The effects of a caffeine pill will peak around an hour after taking a pill, although these numbers can change significantly from user to user.
Q: How long does a 200 mg caffeine pill last?
A: Caffeine stays in your system for 4 to 6 hours on average, and it has a half-life of about 5 hours. If you consume 200mg of caffeine (the dosage used in most pills), then you’ll still have 100mg of caffeine left in your body after 5 hours.
Q: Do caffeine pills help you lose weight?
A: Yes, evidence suggests that caffeine pills can enhance weight loss results. Caffeine is a well-known metabolism booster. Studies show caffeine can raise metabolism by 3-11% and increase fat burning by up to 29%.
Q: What drugs can make you skinny?
A: Caffeine pills, appetite suppressants, and certain prescription drugs can make you skinny. However, you should only use weight loss drugs as recommended by a physician. A conversation with your healthcare provider should preface any new drug or treatment regimen for weight.
Q: Can caffeine pills cause weight gain?
A: Caffeine is not linked to weight gain on its own, although diet and lifestyle factors could cause you to gain weight while taking caffeine pills.
Q: What happens if you only drink coffee and don't eat?
A: Drinking coffee increases the production of stomach acid, although it does not seem to cause digestive issues in most people. Therefore, drinking it on an empty stomach should be perfectly fine. However, you may notice you feel the effects of caffeine faster and more powerfully than if you were drinking coffee with a full stomach.
Q: What do caffeine pills do to your body?
A: Caffeine stimulates the central nervous system, acts as a diuretic (causing you to urinate more), increases stomach acid, and raises blood pressure, among other effects. Caffeine affects your body the same way regardless of whether you take it via pill, coffee, or tea.
Q: How does caffeine work?
A: Caffeine works by mimicking adenosine, a compound that’s produced as a by-product as your neurons fire when you’re awake. As adenosine levels decrease, your body believes it’s getting ready for sleep. Caffeine mostly targets the A1 receptor, and it takes about 5 to 6 hours for your body to process it.
Q: Are caffeine pills better than coffee?
A: Caffeine pills remove the acidity of coffee, although your body absorbs caffeine in mostly the same way. Some people don’t like the taste of coffee, while others find it irritates the digestive tract.
Q: Is 200 mg of caffeine a lot?
A: An average cup of coffee contains 80mg to 120mg of caffeine. A Starbucks grande coffee contains 260mg to 360mg of caffeine. Studies have shown that it’s safe for an average person to consume around 400mg of caffeine per day.
Q: Is it OK to take caffeine pills every day?
A: It’s safe for most healthy adults to take caffeine pills daily, assuming you are maintaining a safe dosage.
Q: Do caffeine pills work like Adderall?
A: Caffeine pills give your body caffeine, and caffeine has been shown to enhance focus and mental energy in many studies. Adderall may also enhance focus and mental energy, although it works in a much different way than caffeine.
Q: Is caffeine hard on the liver?
A: Most studies suggest caffeine has limited impact on your liver. In fact, recent research has shown that caffeine helps the body break up the fat stored in liver cells, which means it may actually be good for the liver.
Q: Do you crash from caffeine pills?
A: Caffeine can cause a crash when taken in pill or coffee form. You may be more likely to crash from caffeine pills because you’re taking all of the caffeine at once instead of drinking it slowly over time.
Q: Are caffeine pills bad for your kidneys?
A: Caffeine pills should not impact the kidneys. Researchers have found it’s safe for people with kidney disease to drink coffee. However, consult your physician to guarantee that caffeine pills won't harm your kidney health.
Q: Are caffeine pills dangerous?
A: Caffeine pills are generally safe when taken in normal dosages by healthy adults. However, the Food and Drug Administration has deemed pure caffeine powder as potentially dangerous, mostly because it’s easy to consume too much caffeine powder.
Q: Is 1000 mg of caffeine too much?
A: It’s recommended that a healthy adult consumes no more than 400mg of caffeine per day. More than 1,000mg of caffeine is a significant amount, although it’s far below the lethal dose.
Q: Is caffeine bad for your heart?
A: Caffeine intake should not be detrimental to your heart health when taken in normal amounts. Caffeine raises your blood pressure in the short term, although this effect is temporary and is minimized over time if you drink caffeinated drinks (or take caffeine pills) regularly.
Q: Do caffeine pills make you poop?
A: Caffeine can stimulate the urge to poop. Studies have shown that caffeine – whether consumed via caffeine pills or coffee – can activate contractions in your colon and intestinal muscles.
Q: What will 600mg of caffeine do?
A: It’s recommended that the average adult takes no more than 400mg of caffeine per day. Taking 600mg of caffeine at once (say, by popping three caffeine pills) can increase the positive and negative effects of caffeine.
Q: What does caffeine do to your heart?
A: Caffeine raises blood pressure in the short term, although this effect is temporary and minimized over time when you drink caffeinated drinks regularly.
Q: Which products have caffeine in them?
A: Caffeine can be found in all types of foods, beverages, and supplements. Coffee, tea, chocolate, soda, and certain medications contain caffeine, for example, as do energy shots, energy drinks, caffeine pills, and other products.
Q: What happens when you overdose on caffeine?
A: Symptoms of a caffeine overdose can include restlessness, nervousness, excitement, insomnia, flushed face, diuresis, gastrointestinal disturbance, muscle twitching, confused thoughts and speech, and irregular heartbeat.
Q: What are the symptoms of caffeine withdrawal?
A: If your body is accustomed to caffeine, then you may experience caffeine withdrawal symptoms if you stop taking caffeine. Blood pressure may drop significantly, causing a rush of blood to the head, which leads to a headache. This headache lasts from one to five days and can be alleviated with an aspirin. Other caffeine withdrawal symptoms include irritability, nervousness, sleepiness, and being unable to work or focus. Extreme symptoms of caffeine withdrawal include nausea and vomiting.
Q: Is caffeine addictive?
A: Caffeine can cause mild physical dependence. To avoid dependency on caffeine, carefully monitor and regulate your use. Consumers should avoid taking caffeine constantly every day, or they might risk addiction.
Q: Can caffeine reduce my risk of certain diseases?
A: Moderate caffeine consumption is linked with a reduced risk of certain diseases, including diabetes, liver disease, gallstones, and Parkinson’s disease.
Q: Can you use caffeine while pregnant?
A: In general, doctors recommend women reduce caffeine consumption when pregnant. Caffeine is a stimulant that can increase your heart rate, which is something that should be avoided during pregnancy. Caffeine also crosses the placenta, and a developing fetus may struggle to handle caffeine even while the adult woman can handle it. Moderate levels of caffeine (150mg to 300mg) may be okay. Talk to your doctor.
Q: Does all coffee contain the same amount of caffeine?
A: Caffeine content varies widely based on the type of coffee and preparation methods. A grande Starbucks blonde roast, for example, contains 360mg of caffeine, while a grande Starbucks dark roast contains 260mg of caffeine. An average cup of coffee prepared at home can contain anywhere from 80 to 200mg of caffeine. It varies widely.
Q: Can caffeine content vary even when I order the same drink every day?
A: Yes. In one study, researchers in Florida placed the same order at the same coffee shop for 6 days in a row and discovered that caffeine content varied widely, ranging from 259mg to 564mg.
Q: Are women more sensitive to caffeine than men?
A: Caffeine seems to have a greater effect on men than women, although the difference is not that significant.
Q: Is it true some skincare products contain caffeine?
A: Some beauty product manufacturers add caffeine to products because of its anti-aging properties. Caffeine also purportedly stimulates blood flow. Plus, it contains antioxidants that smooth skin and reduces the appearance of fine lines and wrinkles.
Q: Can caffeine aggravate symptoms of anxiety?
A: As a stimulant, caffeine may exaggerate symptoms of anxiety. Some doctors may recommend that people with anxiety disorders avoid caffeine because it can aggravate symptoms.
Q: Can caffeine kill you?
A: Caffeine overdoses are rare, although they can be fatal. Caffeine overdoses are generally linked to ingesting too much caffeine in pill or powder form. A dose of about 10g of caffeine (approximately 85 cups of coffee) can be fatal in adults.
Q: What’s the best time of day to take caffeine?
A: Studies have shown that the best time to take caffeine is mid-morning, between 9 and 11:30am, or in the afternoon, between 1 and 5pm. While many people drink caffeine early in the morning (7 to 9am), your body may not need caffeine immediately to start the day. You naturally go through cortisol boosts throughout the day, with a daily peak between 8am and 9am for most people. Cortisol makes you alert, wakes you up, and controls many biological processes. When you drink caffeine too early, it may be wasted because you are already naturally at your alertness peak (even if you may not feel like it).
Q: Does caffeine help with workouts?
A: Caffeine can increase fat burning during workouts, triggering your blood cells to release fatty acids into your bloodstream. However, some caffeine compounds can also cause a crash, so consumers should carefully evaluate specific products to make judgments on their capacity to assist with weight loss.
Q: Does caffeine boost memory?
A: Studies show that caffeine may temporarily boost memory. This study, for example, found that you’ll have a slightly easier time remembering events that occurred while you were caffeinated.
Q: How much caffeine is in tea?
A: An average cup of tea contains 10 to 80mg of caffeine per mug. Caffeine content varies by type of tea, with black tea containing 20 to 80mg per mug, oolong tea containing 10 to 60mg per mug, green tea containing 10 to 40mg per mug, and white tea containing 10 to 35mg per mug.
Q: Should you combine caffeine with L-theanine?
A: Tea has a chemical called L-theanine inside. L-theanine may soothe your nerves, calm anxiety and stress, and boost focus. Some stack L-theanine with caffeine to nullify the negative effects of caffeine.
Q: Do herbal teas contain caffeine?
A: No, herbal teas are naturally caffeine-free. They’re made of a blend of herbs, spices, and fruits.
Best Caffeine Pills 2023 Final Thoughts
Caffeine can do wonders, not only for your physical state but also for your mind. Choosing the right supplement for you should be a breeze now that you know what to look for and some of the supplements which are on the market.
Remember that dosage is very important and determining the right amount might take some time, but it’s very crucial and can be super beneficial overall. It is also super important to not overdose on caffeine and to keep yourself in check, as well as keep your diet in mind when looking at quantities of caffeine that you are consuming on a daily basis.
If you determine that caffeine side effects are particularly strong when you take caffeine, it might be a good idea to search for products that also contain L-theanine. The same goes for those who are looking for a mental boost rather than a physical performance boost.
As with any supplement, we strongly suggest that you speak with your doctor about your intentions when it comes to caffeine. There are possibilities that you should not take any additional caffeine at all depending on your medical conditions and any other medications that you may be taking. For example, people who are obese might be at risk for heart problems and should be screened thoughtfully before any caffeine supplements are introduced into their system. There are other situations during which you should avoid extra caffeine or higher than normal dosages.
Your body is unique in its own way, so the effect of caffeine on your specific body might be different from others. Don’t base your dosage on anyone else’s dosage and don’t expect the same results as someone else might have. Keep to what you know and get the right amount of caffeine you need to accomplish whatever your goals might be, as long as it’s within reasonable limitations and as long as you have reasonable expectations. Caffeine can do wonders, but only if you take it correctly.
