Skratch Labs Launches Electrolyte Booster and Reintroduces Everyday Drink Mix as Unsweetened Sport Drink Mix

August 26, 2025

New additions complete the Skratch Labs Hydration System, giving athletes more ways to personalize hydration

August 26, 2025 (Boulder, CO) /ENDURANCE SPORTSWIRE/ – Skratch Labs, the Boulder-based leader in performance nutrition, announces the launch of Electrolyte Booster, a new unflavored electrolyte mix that can be easily added to any sports drink to customize sodium levels to an athlete’s individual needs, without a salty taste or added calories.

The amount of sodium that athletes lose in their sweat is highly variable and largely determined by genetics. Some athletes lose as little as 400mg of sodium per liter of sweat, while other athletes may lose as much as 2000mg of sodium per liter of sweat. Through the research and expertise of founder and sports physiologist, Dr. Allen Lim, Skratch Labs has developed the Electrolyte Booster for athletes who require more sodium than standard hydration mixes and sports drinks provide, whether due to high sweat sodium losses, long training sessions, or hot and humid conditions. Each serving delivers 400mg of sodium from gut-friendly sodium citrate, along with potassium and magnesium. Because it is unflavored, zero calories, and free of salty taste, Electrolyte Booster can be added to any Skratch Labs drink mixes or an athlete’s drink of choice, allowing hydration to be adjusted independently of fueling. Packaged in 60-serving jars, Electrolyte Booster provides a simple, consistent way for athletes to fine-tune sodium intake for their training and racing.

In addition to the launch of Electrolyte Booster, Skratch Labs reintroduces its Everyday Drink Mix under a new name – Unsweetened Sport Drink Mix. Each serving of the unchanged formula provides 400mg of sodium from sodium citrate and offers athletes a sugar-free, unsweetened option for times when they don’t need fuel in their bottle or simply prefer a lighter taste. Unsweetened Sport Drink Mix is available in Lemon + Lime and Salted Margarita, the latter returning to the permanent lineup by popular demand after debuting as a limited seasonal flavor. Both flavors will be sold in 20-stick caddies and 30-serving pouches.

“Hydration is personal because every athlete loses a different amount of sodium in their sweat,” says Dr. Allen Lim, founder and sport physiologist at Skratch Labs. “By listening to athletes, studying the science, and testing prototypes at some of the biggest events in the world, we recognized the need for more flexible, customizable, and practical hydration options. With Electrolyte Booster, athletes can add more sodium when conditions demand it without extra flavor, sugar, or calories. With Unsweetened Hydration Sport Drink Mix, they get light, real-fruit flavor and sugar-free electrolytes for times when they don’t need fuel. Together with our original Sport Drink Mix and Super High-Carb Drink Mix, these products complete a hydration system designed to work for real athletes in the real world.”

With these additions, Skratch Labs completes its Hydration System, a four-part lineup designed to give athletes complete control over how they hydrate and fuel. The system includes Unsweetened Hydration Sport Drink Mix, a sugar-free option to keep hydration separate from fueling with a lighter taste; Hydration Sport Drink Mix, the fan-favorite original Skratch product, which combines electrolytes with simple carbohydrates for fast energy and fluid absorption; Super High-Carb Drink Mix, powered by complex carbohydrates for sustained fueling during long, intense efforts; and the new unflavored Electrolyte Booster, which adds sodium without calories or taste. Together, these products create simple building blocks that can be used alone or mixed and matched to meet the unique demands of any workout, race, or environment.

Just in time for autumn races, Electrolyte Booster and Unsweetened Hydration Sport Drink Mix launch, giving athletes time to dial in their nutrition strategy for marathon season and fall riding. Skratch Labs also offers an extensive library of free resources on its blog to help athletes learn about hydration and nutrition science, and their full-time registered dietitians on staff also provide sodium sweat testing at the brand’s headquarters in Boulder, CO.

About Skratch Labs:

Born in Boulder, CO, in 2012, Skratch Labs is a performance nutrition innovator that helps athletes be better. Founded by two cycling pros who spent years on the Pro Cycling Tour watching teammates consume bad-tasting sports nutrition products that caused digestion issues, they created a “secret drink mix” composed of real sugar, salt, and fruit powder mixed in a 5-gallon paint bucket for their team. More than a decade later, Skratch Labs’ approach is the same: help athletes perform better by solving their nutrition problems without causing new ones, using real food ingredients.
