Roctane takes athletes' top choice for an energy gel, GU, amplifies the original recipe and then adds new ingredients to boost performance in sustained, high-intensity efforts. Here's how it's done:
GU starts with a superior mix of complex and simple carbohydrates that provide quick and sustained energy, electrolytes for replenishment and caffeine to tap more power and diminish pain.
From there GU increases the amount of histidine, an essential amino acid, to act as a buffer and slow the energy-sapping lactic acid build-up in muscles.
GU mixes in higher levels of citrates (potassium citrate, sodium citrate, and citric acid) to help speed the conversion of carbohydrates into energy molecules and, like histidine, help mitigate acid build-up.
GU also adds more of the branched chain amino acids (BCAAs) leucine, valine and isoleucine to serve as another fuel source, aid in recovery and help maintain mental focus and reduce fatigue by limiting the central nervous system's production of serotonin.
Finally, GU adds a new ingredient, the amino acid complex Ornithine Alpha-Ketoglutarate (OKG) which limits the body's tendency to break down muscle protein tissue during extremely hard training and racing days. OKG keeps you going longer and promotes a speedier recovery.
Roctane Ultra Endurance Energy Gel packs 100 calories into every packet. It's an ideal serving size to suck down 15 minutes before training or racing in order to top off your electrolyte and glucose stores, followed by one every 30-45 minutes along the way, washed down with a few sips of fluid.
