Science in Sport Go Isotonic Energy Gel

The Science in Sport GO Isotonic Energy Gel delivers fast-acting carbohydrate energy in a unique isotonic formula that absorbs quickly without requiring additional water intake. Recognized as the world's first isotonic energy gel and winner of the Queen's Award for Enterprise (Innovation) in 2015, this proven fueling solution remains the go-to choice for elite athletes across endurance and team sports worldwide who demand reliable energy delivery without gastrointestinal complications.

Each gel contains 22 grams of carbohydrates formulated with maltodextrin, a clean, single-source carbohydrate that delivers reliable energy for both endurance efforts and high-intensity sessions. This straightforward formulation provides the rapid fuel necessary to maintain pace, push through fatigue, and finish strong when carbohydrate depletion threatens to compromise performance. Unlike complex dual-source formulations designed for ultra-endurance efforts, the GO Isotonic Gel's single-source approach offers versatile fueling that works across a broader range of exercise intensities and durations.

The revolutionary isotonic formula sets the GO Gel apart from conventional energy gels that require water consumption for proper absorption. By matching the body's natural fluid concentration, the isotonic design allows the gel to pass quickly from the stomach into the intestine where carbohydrates are absorbed, eliminating the bloating, sloshing, and stomach upset common with hypertonic gels that draw water into the gut. This means athletes can fuel aggressively without carrying or consuming extra fluids, a significant practical advantage during races, training sessions, or any situation where hydration opportunities are limited or inconvenient.

The gel absorbs smoothly and digests rapidly, making it easy on the stomach even during intense exercise when blood flow is diverted away from the digestive system. This fast energy delivery prevents the performance decline that occurs when carbohydrate stores deplete, one of the biggest causes of fatigue during exercise. By replacing depleted stores with fast-acting carbohydrates, the GO Isotonic Gel improves endurance, delays fatigue, and maintains performance levels when effort intensifies and energy demands peak.

Lightweight and portable, the gel fits easily in jersey pockets, race belts, or hydration packs for convenient access during training, competition, or any workout demanding sustained energy. The tear-open, squeeze-and-go format enables quick consumption without fumbling or slowing pace. Formulated without artificial flavors, the gel delivers clean, effective ingredients focused purely on performance.

Depending on sport and intensity, athletes should aim for 1–3 gels per hour to reach the 60–90g carbohydrate target that supports sustained performance across most endurance activities.
