Frequently Asked Questions

GU Roctane contains higher levels of both sodium and amino acids compared to the original GU Energy Gel. This enhanced formula is specifically designed for ultra-endurance athletes involved in high-mileage training or very intense, long-duration events.

No, not all GU Roctane flavors contain caffeine. While many popular flavors do, and some even contain extra caffeine, there are specific caffeine-free options available for athletes who prefer to avoid stimulants.

GU Roctane uses a dual-carbohydrate system of maltodextrin and fructose. This blend utilizes non-competing absorption pathways, allowing the body to take in and use carbohydrates more effectively for immediate and long-lasting energy, all while minimizing stomach upset.

The amino acids in Roctane, including BCAAs, taurine, and beta-alanine, serve several purposes. They help to reduce mental fatigue, decrease muscle damage, support heart function, and buffer against lactic acid buildup during intense exercise.

Roctane contains elevated levels of sodium (from sodium citrate and sea salt) and potassium. These electrolytes are crucial for maintaining the body's fluid balance and helping with hydration, which is vital during heavy sweating.

Yes, the majority of GU Roctane energy gels are formulated to be gluten-free and vegan, making them suitable for athletes with specific dietary needs.

Athletes should use GU Roctane about 15 minutes before intense training or a race, and then every 30 to 45 minutes during the activity. This timing helps maintain a steady supply of energy and supports electrolyte balance.
