Easy to open and swallow, each sachet contains 23g of carbohydrate energy and a high dose of caffeine (100mg). Building on the success of IsoGel Xtreme, HIGH5 have tweaked the name and freshened the packaging but retained the performance you love. Energy Gel Aqua Caffeine Hit is a fresh tasting gel that is not thick or overly sweet. Unlike many other gels, you don’t need to drink extra water when taking the gel. It has a consistency more like a sports drink. When endurance racing you should always ensure that you are also well hydrated. ZERO is a great partner product for Gel Aqua. Please note it's not intended for continuous use during training or an event. Excessive amounts of caffeine can lead to side effects like a headache, dizziness and gastrointestinal distress. If you wish to use caffeine continuously throughout your training or event, then switch to standard Energy Gel Aqua Caffeine which has considerably lower caffeine content (30mg/sachet).
