This ‘double strength’ Go Energy + Caffeine Gel is based on the same formula as the innovative SiS GO Isotonic Energy Gel, with the addition of 150mg caffeine; double the caffeine for performance, in one gel. I have tried all flavours on this list and, with the exception of orange, found them all easily digestible, although the orange flavouring felt a bit heavy in the mouth. Consuming carbohydrate during endurance exercise delays fatigue and boosts performance, but the amount that can actually be delivered to the working muscles is limited by the rate at which it can be absorbed from your digestive tract. Electrolyte drinks containing six-eight per cent carbohydrate are known as isotonic – they contain the same concentration of dissolved particles (salts and sugars) as body fluids, which promotes hydration. 2:1 fructose drinks What are 2:1 fructose drinks? Studies show that consumption of a carbohydrate drink during rides lasting over 60 minutes is an effective way to boost endurance. By providing the working muscles with additional fuel you can delay fatigue, with some research suggesting up to a 20 per cent improvement in performance during exercise lasting 90 minutes or more.

Still aim to hit 60g of carbohydrate per hour, using electrolyte gels around other SiS GO products e.g SiS GO isotonic Energy Gel Hydration supplements are ideal pre workout or throughout your workout. It is also very important to hydrate yourself after a workout. Combine with other energy supplements from the Beta Fuel range to achieve hourly 80-120g carbohydrate intake Tropical: Carbohydrate mix (93%) (Maltodextrin (from Maize), Fructose), Citric Acid, Electrolytes (2%) (Sodium Chloride, Calcium Lactate, Potassium Chloride, Sodium Citrate, Magnesium Citrate), Natural Flavouring, Sweetener (Aspartame). Contains a source of Phenylalanine. But do you actually need Go Hydro (or any other similar product), with all these added electrolytes, just to stay hydrated? The answer is not straightforward.Use this gel in combination with other SiS GO products to take in 60g of carbohydrate per hour for exercise lasting over 90 minutes. Fuelling every 20 minutes with a gel is a simple way to hit this carbohydrate target and keep performance at its peak with enough readily available energy for the body to perform

As such, I can only say how well I think it works, and get the details behind the product from the people who make it. As an athlete of any sport or a specialised endurance athlete, our GO Energy Isotonic Gel can be used on its own to fulfil your fuelling requirements, or combined with other products from our extensive range of Mixed GO Isotonic Energy Gelsenergy spplements. It is well documented that both carbohydrate depletion and dehydration are two of the major causes of fatigue in endurance exercise. In addition to ensuring optimal carbohydrate stores and hydration status before exercise, delivering additional carbohydrate and fluid during exercise is known to improve performance, race times and delay the onset of fatigue. Common mistakes made by endurance athletes are to consume too much carbohydrate at inappropriate concentrations (such that it can not be readily absorbed) or too little carbohydrate at low concentrations which although will increase fluid delivery will compromise carbohydrate delivery. For rides lasting over an hour, try swapping your usual sports drink or energy gelfor a 2:1 product to increase carbohydrate delivery from 60g to 90g per hour – this equates to 1,500ml of a drink, three gels or three bars. The loss of electrolytes in sweat (primarily sodium) is also exacerbated during prolonged exercise or in hot weather. Failure to replace electrolytes, or dilution through excessive intake of plain water can result in hyponatremia (low levels of sodium) leading to muscle cramps, lethargy, nausea, headaches and in severe cases, death.

Beta Fuel gels can be used in combination with other products within the Beta Fuel range to allow you to devise the best fuelling solution for you Lemon/Lime: Carbohydrate mix (93%) (Maltodextrin (from Maize), Fructose), Citric Acid, Electrolytes (2%) (Sodium Chloride, Calcium Lactate, Potassium Chloride, Sodium Citrate, Magnesium Citrate), Natural Flavouring, Sweetener (Aspartame). Contains a source of Phenylalanine. Just like the Beta Fuel Energy Gel, our Nootropics Gel contains 40 grams of carbohydrate, with added nootropic substances that can enhance cognitive performance, giving you that mental lift you might need, especially at the latter phases of exercise. The 150mg caffeine energy gel is designed for individuals who want to see the performance benefit from caffeine in a ‘double strength’ format. Unlike the 75mg gel, the 150mg provides a larger dose of caffeine and should be used when the individual needs a mental boost. It is recommended that this gel is taken towards the end of endurance exercise, with the caffeine effect lasting until the end.
