GO Energy Plus Caffeine Gels

Style & Size:



The first time you try one of Science in Sport's GO Energy Plus Caffeine Gels, it's going to feel a little bit weird. Not in a bad way, mind you, but the company's highly scientific approach to athletic nutrition has resulted in a noticeably thinner consistency gel than you're probably used to. This allows faster absorption regardless of your water bottle status, and leaves none of that weird sticky aftertaste that can be so disgustingly distracting when you're on the rivet and just trying to survive to the finish line.

While these gels aren't alone in harnessing caffeine's benefits for lowering fatigue perceptions, they do set themselves apart from the crowd with their isotonic designation. This means they're designed to mirror the dissolved particle concentration of the fluid in your body's cells, which allows for easy transfer across cell membranes. That means the energy they contain goes from your stomach to your blood stream without needing extra water. Comparatively, thicker gels are hypertonic, meaning they have a higher concentration of dissolved particles than your cell fluid and require extra liquid in order to encourage absorption. If you don't drink the recommended volume of fluid with them, hypertonic gels absorb slowly and can cause some rather unfortunate stomach discomfort. And if you've ever been low on water but needed some energy, you know first-hand that puffy pain is not something you want to deal with in the middle of a race.

In short, the GO Energy Plus Caffeine Gels deliver 75mg of caffeine and 22g of carbohydrates quickly and aren't dependent on having a glut of water on board to access that energy boost. That does mean that each packet is a slightly larger volume than the gels you're used to, which allows that thinner isotonic consistency while still delivering the necessary nutrients to fuel the ride.

For the racers among us, the GO Energy Plus Caffeine Gels also offer some peace of mind from the whirling chatter of tainted supplements and suspicious substances. These gels are certified through the Informed Sport Evolved Certification program, so they undergo vigorous testing through a third party, world-class anti-doping lab that analyzes pre-production raw ingredients and post-production product. The organization also completes site audits to ensure that these gels contain quality ingredients and are free from prohibited substances, which means everything if you're serious about riding clean.

The Science in Sport GO Energy Plus Caffeine Gels are available in berry or citrus, with a light flavor profile that won't overpower in the saddle. They're also vegan, gluten-free, lactose-free, wheat-free, and nut-free.
