Scratch Lab's Hydration Sport Drink Mix was created to replace the electrolytes lost in sweat during activity using real fruit for flavor. This gives it a light taste that will have you going back for more without leading to an upset stomach. Scratch understands that you have a choice when it comes to nutrition, so it develops products to help you perform at your best. When it comes to getting your hydration right, these simple and natural ingredients are easy to digest and replenish the body quickly and efficiently. Keeping it simple is the Skratch way, but simplicity doesn't necessarily preclude room for improvement. This new recipe proves that point by including 10% more electrolytes to better match what's lost when you sweat. The Matcha Green Tea & Lemon flavor contains about 16mg of naturally occurring caffeine from Matcha tea in a 16oz serving. For comparison, an 8oz cup of coffee has 70-100mg of caffeine. Regardless of caffeine content, all of the drink mix flavors are non-GMO, gluten-free, dairy-free, vegan, and kosher.
