Behind the Scenes: How Australian Institute of Sports Nutrition Guidelines Shape Our Product Formulations

The Australian Institute of Sports Nutrition is the country’s leading authority on supplementation. Any athlete who looks for reliable products should know that the company they trust follows the AIS’s advice and best practices to create reliable products that are proven to benefit performance, endurance, and recovery. Fixx Nutrition is a proud Ozzie brand, and we follow the Australian Institute of Sports Nutrition’s guidelines in every formula. 

In this guide, we’ll break down how the AIS informs our product formulations, including CrampFix and Fuel X, our two top-selling products chosen by professionals and marathoners throughout the country. 

Understanding AIS Nutrition Guidelines

Sports put a unique strain on the body. Every muscle, including the heart, is impacted by the demand for greater energy and output. For high-performance or endurance athletes, nutrition is even more vital to preserve their energy, maintain a consistent output, and ensure they avoid some of the health risks that can stem from dehydration and overexertion.

The AIS provides a clear, comprehensive sports nutrition framework to help athletes understand what their bodies need and how to provide it effectively for sports performance. 

For example, their energy availability resources detail the factors that affect fueling needs and help athletes understand how to care for themselves during physical activities. 

Supplementation Guidelines

The AIS classifies sports supplements into four groups: 

• Group A supplements have a strong scientific foundation and follow evidence-based protocols. They can include sports drinks, sports gels, and electrolyte supplements. 

• Group B supplements have emerging scientific support, such as Vitamin C, fruit-derived polyphenols, and pickle juice. They work, but they need further research to prove their scientific validity. 

• Group C supplements are not supported by scientific evidence OR no research has been performed to explore their benefits; examples include magnesium, vitamin E, prebiotics, and alpha lipoic acid. 

• Group D supplements are banned or have a high risk of contamination that could trigger a positive doping test; they include stimulants like ephedrine, prohormones and hormone boosters, peptides and GH releasers, beta-2 agonists, Selective Androgen Receptor Modulators (SARMS), metabolic modulators, and colostrum.

A Closer Look at Fixx Nutrition’s Formulas 

CrampFix

CrampFix is the number-one cramp relief formula specifically designed for athletes. Designed with rapid relief in mind, we help runners, swimmers, cyclists, rugby players, and more sports enthusiasts keep their muscles firing strongly and recovering smoothly. Our electrolyte-based formula uses pickle juice as its inspiration, triggering a rapid relief response that targets neuromuscular fatigue and restores healthy function.

Fuel X

Fuel X has a hydration formula rich in electrolytes and carbohydrates. Fuel X enhances hydration to boost endurance, and it’s been strategically designed to provide sustained energy without the gastrointestinal discomfort so common with other supplements. Our Fuel X Pro product range offers additional nutritional support for endurance athletes. with the inclusion of amino acids (alanine and leucine) for improved performance and endurance. 

Gel X

Gel X helps you fuel safely on the go with easily absorbed carbohydrates. It’s designed to help you get a dose of quick, digestible energy without the spike in blood sugar levels. Free from additives and artificial sugars, Gel X offers a pure, clean, effective fueling solution.

Caffeine Shots

Our caffeine shots boost energy with naturally occurring caffeine. This eliminates concerns over stimulants or synthetic products that could harm your hormone levels or negatively impact your performance. In addition to our standard Cold Brew, we also offer a sugar-free formula. Perk up your energy levels when you need to without worrying about what’s in your body. 

The Importance of Using Reputable Supplements 

Athletic professionals and even casual sports players need to be mindful of what they consume. Most importantly, they have to ensure they’re only taking products that have been designed to meet their needs. 

There are plenty of over-the-counter sports products that offer high doses of caffeine and sugar, but they aren’t rooted in the science of endurance, sustainable performance, and healthy recovery. That’s where we stand out. 

Before you ever buy a product, be sure to check its ingredient list and origins. How is it manufactured? How is it tested? What efforts has the manufacturer made to ensure its safety and quality?
