The Core Components of GU Nutrition
At the heart of what is GU nutrition is a scientific approach to fueling the body during endurance activities. The products are engineered with a specific combination of ingredients to deliver quick energy, maintain hydration, and support muscle function.
The Dual-Carbohydrate System
Unlike many single-source sugar products, GU uses a patented dual-carbohydrate blend of maltodextrin and fructose. This system is crucial because it utilizes non-competing pathways for carbohydrate absorption, allowing the body to take in more fuel per hour with minimal stomach distress. The maltodextrin provides quick-acting energy, while fructose is metabolized slightly slower, offering a more sustained release of fuel.
Essential Electrolytes
Electrolytes are vital for maintaining fluid balance and muscle function, especially as they are lost through sweat. GU products are formulated with a key electrolyte blend, primarily sodium and potassium, to aid in hydration and prevent fatigue related to dehydration. Sodium, in particular, helps your body absorb and retain fluids more efficiently.
Branched-Chain Amino Acids (BCAAs)
Amino acids are the building blocks of protein and play a role in muscle recovery. GU products include branched-chain amino acids (L-Leucine, L-Valine, and L-Isoleucine) to help reduce muscle damage, mitigate mental fatigue, and assist in muscle repair during intense exercise.
Optional Caffeine Boost
For many athletes, a caffeine boost can enhance performance by increasing focus and decreasing the perception of effort. Many GU products are available with or without caffeine, providing an option for a mental lift during prolonged activities without exceeding beneficial amounts.

How to Incorporate GU into Your Training
For optimal results, it's essential to follow a strategic fueling plan. GU recommends timing your intake to prevent energy dips, or 'bonking'.
- Before Activity: Take one serving (a gel, chews, or a stroopwafel) about 5 minutes before starting your workout to top off your glycogen stores.
- During Activity: For efforts over 45 minutes, consume one serving every 30-45 minutes. For longer efforts, particularly those over 2.5 hours, you may need to increase your carbohydrate intake, possibly utilizing Roctane products.
- Hydrate with Water: Always wash down your energy gels or chews with a few sips of water. This aids in digestion and speeds up nutrient absorption. Consider using Hydration Tabs in your water bottle for additional electrolyte support.
- Practice in Training: Never try a new fueling strategy on race day. Practice with GU products during your training to find out what works best for your body.
