IsoGel energy gel

High 5’s IsoGel Plus has a consistency more like a sports drink than a gel and is formulated to be consumed without water.


Each 60ml sachet contains 23g of carbohydrate plus an additional 30mg of caffeine, which can help fight fatigue and prolong endurance during longer training sessions/races (when used in conjunction with ordinary gels).

In use, the gel boasted a refreshing consistency and a light authentic citrus flavour (courtesy of 15% added lemon and orange juice). If you’re after a caffeinated gel, High5’s Isogel also provides very good value at just 4.3p per gram of carbohydrate.
