Depending on the distance of your run, we recommend bringing a few QuickFix Shots or a 50ml Multi-Serve Bottle in your pocket, belt, or pack.


Drink 1 x 20ml QuickFix SHOT or 10-20ml about 5 minutes before starting your run or when you normally cramp. If you are running a shorter distance, one shot will provide 40-60 minutes of relief. If you are still running, have another 20ml shot of CrampFix. Most marathon runners drink one shot at around the 30 km mark and will save one just in case they cramp at the end. 


Drink 15-20ml of CrampFix® at the first signs of cramping for rapid relief within 30 seconds to 2 minutes.


Drink 10ml of CrampFix® after running to prevent post-exercise cramps and to reduce muscle tightness. If you struggle with night cramps after a run, keep a bottle beside your bed or try our Rapid Mouth Spray.

How It Works

CrampFix® treats muscle cramps through the neuro-muscular system. Instead of treating the cramping muscle itself as most commonly done, CrampFix® treats the overactive nerves that are causing the muscles to cramp.

Drinking 10-20mL of CrampFix® stimulates the sensory nerves in the mouth and throat. A signal is then sent through the spinal cord to inhibit the overactive nerve signals. The overactive nerve signals going from the nerves to the cramping muscle are interrupted and the cramp is rapidly relieved or prevented.


Our sports range consists of our single-serve QuickFix Shot Sachets and our Flip-Top Lid Squeeze Bottle.

Our 20mL QuickFix Shots are the perfect size to fit in your pockets, running belts, and backpack. We designed our packaging to be hassle-free and portable because we know that’s the last thing you need to worry about when racing. Each sachet contains 20ml of CrampFix®, which is just the right amount to prevent and relieve muscle cramps and tightness. When opening each sachet, just tear it halfway to open. We know they can be a little tricky, but you only need to open them slightly as being a liquid it comes out easily.

Our 50ml Flip-Top Lid Squeeze Bottle contains 3-5 serves and is made from soft plastic so it is easy to squeeze into the mouth. The packaging has a flip-top lid so it can be reused and accessed again easily. These are perfect for long-distance runs so you can continually have small sips whilst running to keep muscle cramps away.

I usually do 4 to 5 ultra trail races every year. The distances are usually between 50km to 165km. Every time I do these runs I always take a CrampFix at the first sign of cramping up and it keeps the cramp away.

I have been looking for something to stop the dreaded leg cramps and with CrampFix I’ve finally found it. Ran a PB in a 1/2 Marathon today and on cue, the left hamstring went into a spasm at 18kms, took a Crampfix shot, and within 30 seconds the cramp had disappeared and I was able to resume my pace.

– Christopher Nicholson

This liquid gold has saved a number of races for me now! Within 5 mins of taking it the cramps reduce and are gone completely within 10mins. I’ve experimented with other options including all the traditional electrolyte replacement, nothing has worked for me, except CrampFix.

I tried your product for the first time over the weekend when I did my own simulation tri leading up to Mooloolaba 70.3. Absolute game-changer for me, no cramps at all when I usually would suffer, even after I was finished and no pains at all the days following. Super happy to have come across your product.

– John Burrowes

Our Formula

CrampFix®’s proprietary formula has been created to contain just the right blend of astringency, pH and mineral content to provide rapid relief. Unlike some cramp management products, CrampFix® is a no-mix, liquid formula that provides an almost immediate effect to get rid of cramps that most commonly appear during endurance activities.

Our formula was specially developed to help high performing athletes to achieve their performance goals. Other cramp relief products on the market such as magnesium supplements, quinine and sodium may assist in preventing cramps; however, these are useless at the time of cramping due to the required time to digest and provide relief. CrampFix® works within 1-2 minutes to alleviate cramps.

CrampFix® is a concentrated proprietary blend so only small doses are required to get rid of muscle cramps. Our sports range has three flavours available; Lemon, Raspberry, & Espresso. All products are 100% natural, gluten-free, & vegan, and are made in Australia to HACCP quality standards. This highly effective formula is Informed Sport accredited, meaning every batch is tested for banned substances for athletes’ assurance.
