Science in Sport GO Isotonic Energy Gel - Fast-Acting Liquid Carbohydrate Gel for Instant Energy - Sports Nutrition - Gluten-Free & Vegan - Apple Flavor - 30 Count

This does the job it is required, to fuel me during my long runs or long cycling activities, they are very affordable for the amount of carbs they have. The taste is very light and does not make the stonach feel heavy or anything like that.

Super delicious, I highly recommend it, great for sports 👏👏

I’m experimenting with gels for the first time while training for a marathon. These taste great and had no strange effects on my stomach as I incorporated them into workouts.

I love this product and use it religiously for cycling. The lemon/lime flavor is pretty decent and it's easy to swallow during my rides. My only complaint this order was the case was completely opened as a botched "reseal" attempt didn't workout. However, I did not issue a return/replace since none of the individual packets were opened...still annoying though. Regardless, I highly recommend this product and the opened case has nothing to do with the actual quality. I feel this product is much more affordable while being better quality than many of its competitors.

I’ve used SIS Isotonic Energy Gels during long runs, bike rides, and races, and they stand out for one simple reason: they’re easy to take when effort is high. The isotonic formula means no extra water is needed, which makes a real difference during intense or hot sessions. They go down smoothly, aren’t thick or sticky, and don’t leave that heavy feeling in your stomach that many gels do. Energy delivery is fast and noticeable, but not harsh. It’s a clean boost that helps maintain effort rather than causing a spike and crash. I’ve had zero GI issues using these, even late in long workouts. Flavor is light and not overly sweet, which matters when you’re taking multiple gels over time. The packaging is also easy to open while moving. If you rely on gels for endurance training and want something simple, effective, and stomach-friendly, SIS Isotonic gels are a strong option.

Nice texture and flavor. No stomach distress

A lot of the negative comments about this product have centered upon the taste and consistency of these gels. My questions are... What gels have a phenomenal (not over sugary) taste? Which don't have an awful consistency, (like thick sludge) requiring water to avoid gagging? The answer, pretty much none. SIS gels lack flavor, I'm good with that. I need my gels to be more effective than 'great' tasting, which SIS has 'just enough' taste (orange best so far). And for consistency, they can't be beat. They go down like water. The only down side may be their size/weight because of the isotonic (water) factor. But if your not an elite participant who gets to lay stuff out on tables/stations in advance, you can handle carrying a few extra ounces around. And if you do ultras, triathlon or trail type events carrying these will be a cinch in your hydration packs, vests or cycling shirt pockets. Hands down best product by far for energy and electrolyte maintenance during endurance events.

It seems to be well tolerated and helps my endurance on bike rides. It is supposed to be isotonic so water not required but I always drink some water with.
