Gatorade is a brand of sports drinks made by PepsiCo. Gatorade's G2 variety contains fewer calories than regular Gatorade. The Powerade brand of sports drinks is made by Coca-Cola and is the main competitor for Gatorade. Powerade Zero has electrolytes but no calories.
G2 is essentially a mixture of water, high fructose corn syrup and electrolytes that provides sodium and potassium. Powerade Zero uses sucralose as a sweetener. Both drinks add coloring and flavor agents as appropriate for each drink. G2 is available in blueberry-pomegranate, fruit punch, grape, lemon-lime, orange and strawberry-kiwi flavors. Powerade Zero varieties include strawberry, mixed berry, grape, orange and lemon-lime.
