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.
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.
Built for Every Stage of Your Effort
Elite-level hydration support — wherever you are in the session.
Before
Start strong with key electrolytes to prep muscles and support hydration.
During
Stay fuelled with fast electrolytes to keep going longer and stronger.
After
Replenish lost salts to aid recovery, reduce fatigue, and restore balance.
