Here is the info from GU:
GU Energy Gel is proud to introduce the most advanced energy gel yet, Roctane, designed for the hardest working athletes in sports. Roctane originated as a premium energy gel developed by company founder Dr. William Vaughan to fuel his daughter Laura’s course record at the Hardrock Hundred Mile Endurance Run in the Colorado Rockies. Now, after years of testing with thousands of elite athletes training for and competing in the most physically demanding sports in the world, it’s your turn to fuel up like a pro.
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:
• We start with GU’s superior 80%/20%mix of complex/simple carbohydrates that provide quick and sustained energy. GU’s original recipe also provides an herbal blend of anti-inflammatory chamomile and stomach calming ginger, along with caffeine to metabolize fat.
• From there we increased the amount of Histidine, an essential amino acid, to act as a buffer and slow the energy-sapping lactic acid build-up in muscles.
• We mixed in higher levels of citrates (Potassium Citrate, Sodium Citrate, and Citric Acid) to help speed the conversion of carbohydrates into energy molecules. Like Histidine, these citrates also help mitigate acid build-up.
