Standard electrolyte tablets are designed for general, slow-release hydration. Cramp Killa is a targeted strike against neuromuscular fatigue. It doesn't just replace the sweat you lost; it actively intercepts the misfiring signals between your brain and your muscles to stop seizing in its tracks.

In less than 90 seconds. When your calf locks up at mile 18, you do not have 20 minutes to wait for digestion. Cramp Killa triggers a neural reflex in the back of your throat, resetting the muscle spindle and releasing your muscles immediately.

Far from it. Whilst sodium is a crucial component, Cramp Killa is an optimised, heavily researched formula. It blends specific trace minerals and neuro-triggers engineered to hack the muscle cramp reflex. All of this is packed into one, tasty gel that's easy to consume.

It is most effective the exact moment a cramp kicks in. Consume mid-race to rapidly kill the cramp and save your race. You can also take it 15 minutes before your toughest sessions as a preventative to help your legs stay fresh for longer.

Absolutely. Whether your fuelling programme relies on Maurten, SIS, or real food, it slots perfectly into your existing strategy without overloading your gut with conflicting sugars.

No. It is formulated specifically for the fragile endurance gut. Because it works via a neurological trigger rather than requiring heavy digestion in the stomach, it absorbs cleanly with zero bloating and zero emergency portaloo stops.

If you imagine a sweet, salty, and citrusy burst of natural flavour that delivers a sharp, refreshing spark to your mouth. It is a tangible sensation designed to instantly reboot your system and leave you feeling limitless.

Yes. Cramps are primarily caused by neuromuscular fatigue, pushing harder than your conditioning allows, not just the heat. A gruelling winter cross-country race or a brutal indoor turbo session will misfire your muscles just as quickly. It is a year-round insurance policy.

Yes. It's Informed Sport certified. Every batch is rigorously tested for clean sport compliance. It contains zero banned substances, meaning you can toe the start line with absolute confidence, whether you are an amateur or racing for a podium.

It is engineered to elite specifications, but a cramp does not care about your Strava ranking. Whether you are hunting a sub-3 marathon, surviving your first century ride, or simply trying to finish a brutal Sunday long run, muscle misfires happen to everyone. If you are pushing your body to its absolute breaking point, this is your insurance policy.
