Fuelstrip is a product that analyzes an athlete's sweat levels and recommends the appropriate amount of sports nutrition to eat.
The strips will change color from orange to yellow to green to blue as the athlete's glycogen depletion progresses. The color determines the number of Fuelchews needed to maintain energy; for example, an orange strip requires one chew, while yellow requires two. The company also offers Fuelade hydration drink mix.
MSRP:Fuelstrip $2.49; Fuelchews $2.49; Fuelade $2.99
