Science In Sport GO Isotonic Energy Gel 60ml - Single Unit (Cherry)

## Who It's For

The GO Isotonic Energy Gel is specifically designed for endurance athletes who require a quick and efficient source of energy during prolonged physical activities. This product is particularly beneficial for marathon runners, long-distance cyclists, and triathletes who prefer not to carry additional water, as its isotonic formula allows for consumption without extra hydration. It is also suitable for athletes who experience gastrointestinal distress with hypertonic gels, as its isotonic nature aids in easier digestion.

## Inside the Formulation

This energy gel is formulated with maltodextrin, a glucose polymer that is rapidly metabolized, providing quick energy through the SGLT1 transport pathway. The isotonic nature of the gel ensures that it matches the osmolality of body fluids, facilitating faster gastric emptying and absorption. Each 60ml serving provides 22g of carbohydrates, which is below the typical 30-40g found in other gels, requiring more frequent consumption to meet energy demands. The gel's simple carbohydrate structure allows for rapid absorption, making it suitable for immediate energy needs during high-intensity efforts.

## On Course: How to Use It

For a 5k race, this gel may not be necessary due to the short duration. However, if used, consume one gel 15 minutes before the start to ensure immediate energy availability. In a 10k race, consider consuming one gel 10-15 minutes before the race to top off glycogen stores. For half marathons, consume one gel 10-15 minutes before the start and another around the 10 km mark to maintain energy levels without the need for additional water. During a marathon, start with a gel 15 minutes before the race and consume subsequent gels every 30-45 minutes, aiming for 60g of carbs per hour. Pair with electrolyte supplements due to low sodium content.

## How It Compares

The GO Isotonic Energy Gel stands out due to its isotonic formulation, which reduces the risk of gastrointestinal distress and ensures quick absorption. However, its single-source carbohydrate limits its effectiveness in maximizing carbohydrate intake, capping it at 60g/hour. The low sodium content also requires athletes to supplement with additional electrolytes during extended efforts. While convenient and easy to digest, the gel's cost per gram of carbohydrate is relatively high, and its flavor options are limited.

## Training Your Gut

To optimize the use of this gel, follow a gut training protocol. In week 1, consume one gel during two moderate sessions to assess tolerance. In week 2, increase to two gels per session, focusing on longer workouts. In week 3, simulate race conditions by using three gels in a single long session. In week 4, conduct a full race rehearsal with planned gel consumption every 30-45 minutes. Start with small doses to assess tolerance, pair with electrolyte supplements for longer sessions, practice opening and consuming gels while on the move, and monitor for any gastrointestinal discomfort during initial trials.

## The Verdict

The GO Isotonic Energy Gel is a solid choice for athletes seeking quick energy without the need for additional water. Its isotonic nature aids in rapid absorption and minimizes gastrointestinal distress. However, its single-source carbohydrate limits its effectiveness in maximizing carbohydrate intake, capping it at 60g/hour. The low sodium content also requires athletes to supplement with additional electrolytes during extended efforts. While convenient and easy to digest, the gel's cost per gram of carbohydrate is relatively high, and its flavor options are limited. Overall, it is a reliable energy source for endurance athletes, but requires careful planning and supplementation for optimal performance.
