Styrkr SLT+ High-Strength Electrolyte

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.

This hypotonic formula packs a massive 1,080 mg of sodium, 280 mg of potassium, 120 mg of magnesium and 60 mg of calcium per sachet – designed specifically for heavy sweating and extreme heat. The electrolyte profile and ratio mimic that of human sweat.

Pure Electrolyte Formula

Zero sugar, zero carbs, zero calories.

The hypotonic formulation ensures rapid absorption while remaining allergen-free, gluten-free and 100% vegan. Styrkr calls this “the perfect hypotonic formulation,” offering a lower-concentration option compared to standard drink mixes. And it’s Informed Sport Certified®.

How to Use Styrkr SLT+

Mix one sachet with 500-750 ml of water and drink pre-, during, or post vigorous training, especially in hot conditions. The convenient sachet format makes it easy to dial in your hydration anywhere.
