Gu

GU Energy Labs is a company based in Berkeley, California, that produces performance sports nutrition products, most notably energy gels. Usually consumed during endurance events, the gels are designed to be quickly and easily digested.

Created for daily training and competition, GU Energy Gel packs energy-dense calories in a portable packet to help sustain energy demands of any duration or activity. The 100-calorie packet contains carbohydrates (maltodextrin and fructose) that use non-competing pathways to help maximize carbohydrate absorption and utilization while diminishing stomach distress. Sodium, the primary electrolyte lost in sweat, aids in hydration by maintaining water balance. The branched-chain amino acids (leucine, valine, isoleucine) may reduce mental fatigue and decrease muscle damage.

All GU Energy Gels are vegan, gluten free, and kosher.
