A QUEST TO KILL GATORADE:

Lim says that Gatorade, Powerade, and their ilk rely so much on artificial and excessive ingredients that their effects are actually the opposite of what’s intended—making athletes not lean and mean but sick and sluggish. With Skratch Labs, his company based in nearby Boulder, he’s dreaming up products that change the way those athletes fuel themselves. At the Skratch Labs kitchen trailer in the parking lot, folks are jockey­ing for free samples of the company’s signature Exercise Hydration Mix powder. “I haven’t touched Gatorade since I tried your mix!” a fan gushes. “Taking Gatorade out!” Lim cries with his typical giddiness, slapping the guy a high five.

Water is also good.
