Elite-level hydration, made simple

SLT+ is your essential high-strength hydration formula, created specifically for endurance athletes. It delivers a potent, scientifically formulated dose of the four key electrolytes lost in sweat to help maintain hydration, reduce fatigue, support performance, and promote faster recovery.

Developed for demanding conditions, heavy sweat loss, and hot climates, SLT+ replenishes and gives back, for maximum function and flavour. Designed for race conditions, in a compact and lightweight single-serve sachet.

Hydration that works as hard as you do. Recovery that starts before the finish.

Performance-tested, athlete-approved
SLT+ delivers 1080mg of sodium plus potassium, magnesium, and calcium to support hydration, reduce cramping, and keep you performing under pressure.

Built on science and shaped by feedback from elite athletes and everyday endurance users. From gut tolerance to flavour, from dosing to mixability, every detail has been tested, refined, and rebuilt for real-world performance.

Tested and certified by Informed Sport. SLT+ is screened for banned substances so you know exactly what you're putting in your body. Nothing hidden, nothing harmful, just clean, regulated, effective hydration, that you can trust.

Years of testing for
demanding conditions
SLT+ is the result of years of testing and scientific refinement engineered for heavy sweat loss, tough conditions, and serious endurance.

From the original SLT05 to SLT07 and now SLT+, Styrkr spent years adapting the formula to give you the best possible hydration, based on your training and racing conditions. Allowing you to choose the right level of hydration, when it matters most.
