The best sports drink is purple
If you ever come up with the idea of marketing your own sports drink, give it a purple color. Purple sports drinks have a greater performance-enhancing effect.Study
Daniel Brown, a sports scientist from Loughborough College in the UK, got 10 non-athletic subjects to run for 30 minutes on 2 separate occasions. The subjects were instructed to exert themselves quite hard.

On one occasion the subjects were given a sweetened low-calorie colorless drink during their session, on the other hand a sweetened low-calorie purple drink.
Results
Speed ​​and distance covered were 4.4 percent greater when the subjects drank the purple product. When the subjects drank the purple sports drink, they rated the exercise as slightly more pleasant than when consuming the colorless sports drink.
