Electrolytes are minerals, like sodium, potassium, calcium, and magnesium, that help your body hold onto fluid, maintain proper muscle function, and keep your nervous system firing. When you sweat, you lose more than just water, you also lose electrolytes, especially sodium. If you don’t replace both, your performance can suffer. Replacing them helps you stay hydrated and perform better, longer.

Our electrolyte profile was developed to match what is in sweat - 400 mg sodium/L, 80 mg potassium/L, 100 mg calcium/L, 80 mg magnesium/L. We include the average amount of electrolytes lost in sweat, especially sodium, so your hydration reflects what your body actually needs. That balance helps your body absorb water faster and makes thirst a better guide during exercise.

Both are built to replace the electrolytes you lose in sweat, especially sodium. But only Sport Hydration Drink Mix contains sugar, which helps increase fluid absorption and provides light fuel. Unsweetened Sport Drink Mix is sugar-free, ideal when you don’t need carbs in your drink or prefer a lighter, less sweet taste.

A small amount of sugar helps your body absorb fluid faster through something called sodium-glucose co-transport - this helps water and electrolytes move from your gut into your bloodstream more quickly. It also gives you a steady source of energy. We use just enough to help you perform, not so much that it overwhelms your gut or your taste buds.

• Original Hydration Sport Drink Mix (with cane sugar)
  Light, refreshing, and lightly sweetened with cane sugar. Made with real fruit flavor that never tastes artificial, so it won’t wear out your palate, even hours into a long ride or run. This is the classic Skratch hydration you can sip all day while training.
  
• Unsweetened Hydration Sport Drink Mix (no sugar)
  Sugar-free and not sweet—by design. This mix delivers a light, real-fruit flavor with a subtle salty taste (especially in Salted Margarita), just enough to remind you it’s doing something without turning into a salt bomb. It’s easy and enjoyable to drink, even outside of workouts.
  

Hydration Sport Drink Mix and Unsweetened Sport Drink Mix both work great on their own, but are also designed to be part of a broader fueling system. Add Electrolyte Booster for more sodium when it’s extra hot or sweaty, or pair the original Sport Drink Mix with Super-High Carb Drink Mix when you need additional calories and carbs, without changing the flavor profile.

We use real fruit for flavor—no emulsifiers or stabilizers—so some settling is normal. Just give your bottle a quick shake before each sip and you’re good to go. We think it’s worth it for flavor that’s real, not fake.
