Depending on the distance of your swim and if it is open water or in the pool, we recommend drinking a shot or 15-20mL before swimming which will provide 40-60 minutes of relief. If you are still swimming, we recommend keeping a bottle at the end of the pool or keeping a shot in your swimsuit and having another shot.


Drink 1 x 20ml QuickFix SHOT or 10-20ml about 10 minutes before you swim or when you normally cramp. Drink one shot every 40-60 minutes to prevent cramps from returning.


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 exercise to prevent post-exercise cramps and to reduce muscle tightness. If you struggle with night cramps after exercise, 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, bento boxes, and tucked in your swimsuits. 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 (great to keep at the end of the pool). These are perfect if you are carrying a pack so you can continually have small sips whilst running or cycling to keep muscle cramps away.

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.

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.
