The G Series Pro is an advanced development by Gatorade that consists of nutritional support at the three different stages of physical activity: before, during & after. The series has come about through the work done at the Gatorade Sports Science Institute & the feedback of world class athletes. Whether you train every single day, competing on a regular basis, or if you exercise a couple of times a week & play in match ups every month or so, getting the most from your body & performing to your maximum still matters; the G Series Pro helps you do that. For the three stages there are three products. PRIME is for before, PERFORM is for during & RECOVER is for after; all are catered very specifically for their respective tasks. This is PERFORM. The fluid helps maintain hydration, & then it is the carbohydrates & sodium that help ensure that fuel stores are maintained as well as electrolyte balance, all of which contributes to maintaining performance for longer. Intense workouts & endurance sports require this blend of carbohydrates, electrolytes & fluid to help athletes compete. Dehydration is a danger for every athlete at every level, but Gatorade G Series Pro 02 Perform is designed to support you every step of the way.* Carbohydrate: 30g (125 calories)* Electrolytes: 250mg Sodium & 60mg Potassium Per 100ml:* Energy: 106k J (25kcal)* Protein: trace* Carbohydrate: 6g, of which sugars: 6g* Fat: nil, of which saturates: nil* Fibre: trace* Sodium: 0.05g* Potassium: 12mg* Magnesium: 5mg
