Criteria Used for Evaluation

Use

Okay, so the effectiveness of a caffeine pill makes sense. But what exactly does the ‘usefulness’ of a caffeine pill refer to? In this case, we mean its practicality, its additional benefits, and the number of adverse symptoms you might experience. Therefore, usefulness simply means its usefulness relative to your lifestyle and how well it fits into it, as well as what it can offer you. Like we mentioned above, some of the caffeine pills on our list were made to be used specifically by athletes and gym-goers. These caffeine pills will typically take effect very quickly, with a much stronger initial release of caffeine and energy. Other caffeine pills are intended to be used by anyone who needs consistent energy and mental acuity for several consecutive hours at a time.

The best, and most useful products though, will offer the consumer multiple uses and multiple benefits. There are several options on our list that are great for taking either before a workout, mid-morning to help you stay focused, when you hit the 3 pm slump and need a boost to get you through the end of the day but not keep you awake all night, and/or just a general aid in keeping you focused to get your to-do list done. As a general rule of thumb, it is a wise decision to opt for a pill that also contains L-Theanine in addition to caffeine. This is because L-Theanine has been proven to help reduce and avoid some of the negative side effects of caffeine – particularly overall jitteriness and the “caffeine crash” that some users experience. Speaking of negative side effects, another metric we used to gauge the usefulness of the product was the number of adverse side effects that consumers experienced.

A caffeine pill can work wonders in helping your mental functioning, but it does not do much good to swap energy and alertness for a whole list of other physical problems. Caffeine has been known to cause (in some cases) serious gastrointestinal issues because it is a diuretic, as well as general insomnia, nervousness, and elevated blood pressure levels. However, it also has many positive side effects aside from increased energy levels, including help in weight control and weight loss, use in asthma and other respiratory issues where difficulty breathing has occurred, and in some instances may help reduce headaches and migraines.

Some of the products on our list come loaded with other healthy micronutrients other than caffeine, which will fit nicely into a holistically healthy lifestyle. For example, Weyland Energy tablets also contain an adequate source of B Vitamins, and the Suntheanine L- Theanine tablets have coconut oil for an added dose of healthy fats. A good caffeine pill will do less of the “bad stuff” (i.e. diarrhea, gas, bloating, high blood pressure, etc.) and more of the “good stuff”. Overall, caffeine pills can be a very useful option for getting in caffeine because they are easy to take, fast, simple, and fit practically into most people’s lifestyles.

Product Purity

We know how important it is to know what we are putting into our bodies nowadays--which is why we took an extra list at the ingredients on each of the caffeine pills we chose for our list. While some are organic, non-GMO, etc. there are some that are not--and you will see that reflected in their overall rating. Some of us are adamant against specific ingredients, and we made sure to provide options for everyone.

So, make sure to take a look at the ingredient list of each product featured on our list and make sure that it is within your own personal preference guideline. It is important to make sure the stuff we put into our bodies are designed to be safe and effective and easy to use. Many people look to supplements like caffeine pills to give them that extra boost to get them through the hardest part of their day. We understand how important these kinds of products are and we also understand how important it is to know that the products we use are pure and accurate and will do what they claim.

That is why the RunnerClick team spent so much time reviewing each product we featured on our guide here. We want to make sure we are presenting the best products available and that you are getting accurate and up to date information. Our goal is to help you determine what caffeine pills are best suited for your unique wants and needs and lifestyle. We made sure to include several different types and formulations so you can have plenty of options to choose from!

Effectiveness

The effectiveness of each product on this list is determined by a few factors. For example, many of these supplements contain additional ingredients that either provide additional boosts of energy or help their core ingredient, caffeine, in being more effective. Another way that the effectiveness of each product can be defined has to do with dosages since a product that requires fewer servings to provide the same amount of caffeine is clearly more effective.

There is little point in buying a supplement if it is not going to be effective and if it does not do what it claims it will do. So of course, you will want to be sure any caffeine pill you choose to use will be safe and effective and that it will give you the boost of energy you want and need without the nasty side effects of some other supplements out there.

Here at RunnerClick we made sure to find the best caffeine supplements to present to you on our list. Our review team tested each product and made sure to focus on how effective they were and how well they delivered on their promise of additional energy and stamina. We made sure to compare every product so only the best of the best made it onto our list!

Taste

One thing any user needs to be mindful of when choosing any supplement to add to their heath and wellness plan is what it will taste like. Many supplements do a great job at delivering what they promise but one of the biggest complaints many users have is that they often have a bad taste or leave a bad after taste once they are taken. When the taste is really off-putting it can make it difficult to take the supplement. While this is not as big of a concern with an occasional supplement like a caffeine pill, it is still something worth considering as you look at your options.

As we reviewed the various caffeine pills we tested we made sure take the taste into account. While most pills have some sort of taste some are much worse than others and we did our best to include the supplements that have the least offensive taste. Because much of this comes down to personal preference and individual levels of tolerance, it is hard to say all of the pills featured on our list are free from a bad after taste, they are some of the ones that had the least complaints of the products we tried and tested.
