Description

Market-Leading Hydration for Maximum Effort.

Why SLT07?

When it comes to extreme efforts, SLT07 sets a new standard in electrolyte replenishment. Engineered for athletes who push the limits, it delivers market-leading hydration levels, with up to 1000mg of sodium per serving. Make no mistake—this is serious hydration, designed to maintain peak performance when the going gets tough.

Key Benefits

  • High Sodium Content: With 500mg or 1000mg of sodium per serving options, SLT07 provides the electrolyte boost you need to stay hydrated during the most intense workouts or competitions. Sodium is crucial for retaining fluids, and SLT07 is formulated to help you stay properly hydrated when it matters most.
  • Complete Electrolyte Balance: Alongside sodium, SLT07 provides essential electrolytes like potassium, magnesium, and calcium to prevent cramps, support muscle function, and aid recovery.
  • Hypotonic Formula: SLT07 is hypotonic, meaning it’s designed for rapid fluid absorption. It delivers electrolytes efficiently to ensure you stay hydrated without the risk of bloating. A hypotonic solution contains a lower concentration of particles than your body’s fluids, allowing it to be absorbed quickly. This is perfect for times when hydration needs to be fast and effective.

Why Is SLT07 Unique?

SLT07 is a one-of-a-kind solution in the marketplace with its high sodium concentration, designed to replace the heavy losses that come with extreme endurance activities. If you’re sweating heavily or working in high heat, losing sodium can significantly impact your performance. SLT07’s market-leading electrolyte content keeps you fueled and hydrated to push further without the risk of dehydration and cramping.

When to Use It?

  • Before: Use SLT07 20-30 minutes before intense training or events to maximize fluid and electrolyte levels.
  • During: Sip regularly during your activity to maintain hydration and avoid muscle cramps—ideal for long, hot, or highly demanding sessions.
  • After: Rehydrate effectively after extreme efforts to speed up recovery and replenish lost electrolytes.

Two Flavour Options

  • Mild Berry: Smooth and easy to drink, perfect for any athlete.
  • Citrus: Light, crisp, and refreshing for longer efforts.

Handmade in the UK

Crafted in the UK, SLT07 is made with precision and care to meet the demands of high-performance athletes.

100% Vegan & Gluten-Free

Hydrate confidently—SLT07 is vegan and gluten-free, providing clean and reliable hydration without compromise.
