Gu's gel delivers 100 calories for a long lasting energy boost for athletes in every sport and at every level. With carbohydrates, amino acids and electrolytes the Jet Blackberry gel goes to work quickly and easily so that you never have to slow down.
Carbohydrates - GU provides athletes with a dose of 100 calories in the form of 70-80% maltodextrin and 30-20% fructose (The ratio depends upon the flavor.). Why the mix? Itís a complex carbohydrate, and studies have shown that some complex carbs are actually digested faster than simple sugars like table sugar and honey.
Amino Acid Blend - GU features a unique blend of amino acids to combat muscle fatigue, accelerate the conversion of carbohydrates into usable energy, and maintain mental focus.
Electrolytes - Sodium and potassium to replenish what is lost during strenuous activity.
Caffeine - Some GU flavors are caffeinated while others are not. We add caffeine for two reasons: It acts as a stimulant and it lowers the perceived effort.
