Science In Sport GO Isotonic Energy Gels, Running Gels with 22g Carbohydrates, Low Sugar, Variety Pack of Assorted Flavours, 60ml Per Serving (7 Pack)

They’re not the cheapest, but the way they work is brilliant. Great hydration, easy to take while running, and no need to carry a bottle with me. These helped me finish my first 10K charity run with zero stops, thanks SIS GO! Price to quality is spot on, they are tasty and they often run good promos too. Long shelf life, and every time you see them lying around they remind you to get out and train. Highly recommend giving them a try.

My go to running gels! Used to get them at home bargains for 89p a sachet, but they seem to have stopped doing them. So £4.99 for 7 sachets is a bargain and a variety of flavours aswell. Long dated - EXP Jan 27, bought May 26.

The gels are good quality and do the trick but I actually found them cheaper in Home Bargains

I've recently started training for a half marathon and these have been a game changer. An energy boost and negate the need to carry a drink with me. They are easy to open and they taste pretty good.

As somebody with experience in fitness and nutrition who recently took up cycling to compete in a 100km charity ride, it was extremely important to me that I had the right fuel when riding. Science in Sport are well known and established providers of cycling nutrition and were my first choice for fast acting carbohydrates. These gels are a staple in cycling nutrition. Anyone out riding for a prolonged period of time will be using up their muscles glycogen stores and quick digesting carbohydrates are required to help replenish those store. These isotonic gels provide your body with easily digestible carbohydrates to fuel your rides. Personally I'd be using one around every half an hour or when I begin to struggle with low energy. They help to provide a quick amount of energy for your muscles and delay fatigue so you can push on or push harder. With a simple tearable tab they are easy to consume whilst riding using only one hand. The tabs can be torn off with your teeth and the gel squeezed out easily. When finished, I'd recommend placing them inside a bag rather than directly into your jersey pocket; it's usually impossible to get all of the gel out, which leads to some leaking and a sticky mess if left in your pockets. The selection box is quite a nice way of sampling the different flavors. Non of the flavors are disgusting, but they equally aren't that enjoyable either. They taste okay and they are gone in a few seconds anyway. Admittedly they are rather expensive but for the price they are convenient.

Good value. Easy to use during exercise

SiS gels have been tried and tested to give Energy boosts during activity. Worth buying one from a supermarket or sports shop first as some may cause stomach upsets. I have used them for years without any problems and always have one or two in my cycling top when out on a ride . One Gel and a drink is all that's required.

The gels are decent. The ingredients are OK and you don't feel the effect as much. They taste as the flavour describes it, fruity! They are easy to swallow and do not need water to get through them. However, I had an issue with my order, one gel was removed with the package open, and I could not return it, unfortunately.

The Gels given to me, is about to expired in less than a month. Very frustrating. Cant even return the product.

this is a perfect supplement for rides.

Ordered in May 2025, received the products that expired in October 2025. Only 5 months to consume the whole box.

Product very good, very fast absortion and a very good size. Nothing too big, or too small. But easy to drink and give you a small push to complete your goal.

I don’t have too much experience running and consuming carb gels, but these are practical and easy to consume without water. Nice flavors too!
