Criteria Used for Evaluation

Taste

While ingesting a product like this is all about enhancing performance, if it tastes good or even great that's a huge bonus. If this wasn't an important factor then GU wouldn't go to the trouble of spending tons of money in research and development to create the 29 different flavors of GU Energy Gels and Roctane Energy Gels that they have. 29 different flavors! Yes, we know that's a lot to choose from, so we scoured the internet and considered over 1400 reviews from real-world users to find the 9 best ones. The 10th is a variety pack because we feel that it's important to be able to give you different options and we loved that one of the options was an option with a ton of different options! Still with us? Good. Yes, we tested and tasted some of the flavors ourselves, but since taste is such a subjective thing we considered actual user reviews and weighted them more highly than our own opinions because they represent a wider variety of tastes and come from people from all different walks of life. Because of this, we feel that this list is a good and true representation of the 10 actual best flavors and not just our admittedly limited opinion.

Flavors

With this criteria we look at whether or not the stated flavor actually tastes like what it's supposed to. Sure, it could say Strawberry-Banana, but does it actually taste like strawberries and bananas? Most likely you've tried a food product that was supposed to taste like something but in actuality it didn't really resemble the real-life food all that much and was probably way too sweet. For the most part we found that GU does a good job of creating products that taste like what their labeled as, but like with everything else some options taste more true to life than others and we reflected this in its rating.

Side Effects

You'd think that even though each product on our list is made by the same company and for the same purpose that they all react the same inside your body. During our research, however, we found that different people reacted differently to different flavors so we wanted to make sure this was reflected in the ratings for each product. This was fairly tedious work to do, as it meant we had to scour and consider a ton of different reviews to find the information. But in the end, we think it was worth it because it means you, our valued readers, are getting the most accurate information about how each of the products on this list can and will affect your most important possession, your body. The most common side effect that energy gels cause is known as gut rot, which is a combination of nausea, bloating, cramping, and diarrhea. The science behind this is complicated, but basically what happens is that sugar loves water and energy gels contain a lot of sugar, which can pull water out of your cells and cause the side effects mentioned above. But fear not! By drinking 11 oz. or more of water along with your energy gel these negative side effects can be neutralized and you'll most likely be able to realize the positive effects of GU energy gels without the negative ones. Every person's system is different, however, and we highly recommend experimenting with different gels and amounts of water, especially if you're going to be using them as an energy source during a race.

Product Purity

Some of the products on this list contain caffeine, which can be a benefit to some and a detriment to others, depending on each person's unique bodily systems, when they take the gel, and what their goals are when they ingest it. Caffeine is best known for its energy boosting properties, but it has also been shown to increase mental sharpness and acuity as well as make the carbohydrates in the gel be more readily absorbed by your body. Additionally, caffeine has been shown to decrease the risk of type 2 diabetes, throat cancer, and has many other benefits as well. If you're a marathon runner, however, be aware that too much caffeine late in a race, after mile 20 usually, can cause your body to override it's natural inclination to slow down and lessen performance in order to prevent causing itself harm. While this may sound good in theory if you're trying to set a new personal record or simply finish a long race, your body has these natural governors in place for a reason, and ingesting caffeine late in a race may help you keep up a high pace during the finish, but that high pace at that stage of the race can also cause your body a lot of harm and make it harder for you to recover. In the end, we believe in moderation in everything, and if you're truly serious about using caffeine as a way to boost your performance in a marathon length or longer endurance race above and beyond what an energy gel gives you we highly recommend you do more research on the subject as it's too complicated and scientific to go into in this forum and your health and well being is one thing we don't recommend outsourcing to others, no matter how much you trust the source.
