Our Sport Hydration Drink Mix was created for a simple purpose—to replace the electrolytes lost in sweat and to provide a little bit of energy when working out, without offending your palate or gut. We initially created this drink because some of the world's best athletes needed better. Conventional sports drinks made them sick. They were undrinkable—too sweet, over-flavored, and didn't even replace what was lost in sweat—which defeated the whole purpose, like fighting thirst with more thirst. The best athletes needed something to safely hydrate, something to quench their thirst, and something to help them perform better. So with their help, we reimagined sports drinks, stripping down what used to be a neon-colored carnival to its bare essentials. In the process, we learned that simple wasn't just better for elite athletes, it was better for everyone who works hard and sweats. The result is a sports drink with minimal sugar (4g per 100 ml) and a ratio of sugar (glucose + fructose) that is optimized for faster absorption, an electrolyte profile that actually matches what is lost in sweat (800 mg sodium, 80 mg potassium, 100 mg calcium, and 80 mg of magnesium per liter), and only real fruit for flavor for a light and refreshing taste that you can drink all day. That's it—less sugar, the right electrolyte profile, and real fruit. So, if you've never met a sports drink you wanted to take home, your luck is about to change. Drink when thirsty and leaking like a busted fire hydrant. Don't drink while deep in the middle of a Netflix marathon session or sending emails (unless, you're also on your trainer). Meaning, if you haven't earned it, you don't deserve it.
