Four key electrolytes that help maintain hydration
SLT+ delivers a high-strength sodium dose (1080mg) alongside potassium, magnesium, and calcium - essential minerals that help the body perform under stress and recover efficiently.

• Sodium (Chloride): Supports fluid balance, helps maintain normal blood pressure, and is essential for muscle and nerve function.
• Potassium (Chloride): Supports normal muscle and nerve function and helps maintain healthy blood pressure levels.
• Magnesium (Citrate): Helps reduce tiredness and fatigue while supporting energy release, muscle function, and electrolyte balance.
• Calcium (Malate): Essential for strong bones and teeth, supports muscle function, and plays a key role in energy metabolism.

Combat energy loss
Electrolytes play a role in energy metabolism and can help reduce the sensation of tiredness during prolonged activity. Maintaining adequate levels supports your body's natural energy-producing processes.

Complete electrolyte profile
Endurance sports can lead to significant sweat loss, which depletes essential electrolytes like sodium, potassium, and magnesium. Replenishing these minerals helps maintain fluid balance, supporting key functions such as nerve signalling and muscle responsiveness.

Muscle function and recovery
Proper electrolyte intake contributes to normal muscle function, which is essential during and after exercise. It also supports processes like protein synthesis and bone health—both vital for recovery and overall performance.

Trusted. Tested. Certified.
Every batch is Informed Sport Informed certified—rigorously tested for banned substances so you can hydrate with confidence, no matter the stage or season.
