CrampFix offers athletes fast, reliable and effective cramp management.

Ideal for triathletes, marathon runners, ultra trail runners, ironman athletes, kayakers, cyclists, rugby, basketball, soccer, hockey, weight lifters, cross-fit, tennis players, and basically anybody who cramps from strenuous exercise.

Also works for outdoor workers, gardeners, builders and people suffering from night cramps.


CrampFix is all-natural formulated supplementary sports nutrition.

It works by blocking the nerves which are causing the muscles to cramp. It works rapidly when cramp strikes and also helps to prevent cramps.

It is a concentrated proprietary blend. Only small doses are required. Ideal for athletes following nutrition plans.

One Crampfix shot sachet activates sensors in your mouth which disrupt the neurological signals to your muscles to ease the cramp in as little as 30 seconds and at most 2 minutes. One shot will give 45-60 minutes of relief. 

  • Lemon, Raspberry & Espresso flavours

CrampFix is easy to use! These sachets provide the perfect amount you need for any scenario. 


Drink one sachet 5 minutes before exercise. In the first 15 minutes of exercise, CrampFix helps drive carb metabolism so you get more energy from carbohydrates.


Drink one sachet at first signs of cramping for rapid relief within 30 seconds to 2 minutes. The proprietary blend of low pH and special/select electrolytes quench acute neuromuscular fatigue, rapidly releasing cramps, so you can continue to perform.


Drink one sachet after exercise to prevent post-exercise cramps and to reduce muscle tightness. CrampFix may assist in short-term recovery and longer-term performance goals.
