A sports drink is a beverage which is supposed to rehydrate athletes and give them energy, as well as extra nutrients. The first sports drink was Gatorade, but there have been several others made since then.

Sports drinks have their largest market in non-athletes. This is because many people like the sweet taste, and drinking sports drinks make them feel like they're athletes or being healthy (from the vitamins and minerals found in sports drinks). This has led some sports drinks to be targeted specifically at non-athletes, such as low-sodium or low-calorie sports drinks, although they are still marketed as being for athletes. Certain sports drinks, such as Red Bull, contain stimulants. In some cases, these stimulants have been known to cause severe strokes and brain damage, causing mental retardation.
