47.6g Carbs. Electrolytes. Amino Acids. Complete Endurance Fuel.

The FIXX Fuel X Pro 55g Lemon Lime is an all-in-one endurance drink mix designed to provide carbohydrate, electrolytes and amino acids in one easy-to-drink bottle during longer training sessions and race day.

Each 55g sachet delivers 200 calories and 47.6g of carbohydrate, alongside sodium, potassium, calcium and magnesium to help replace electrolytes lost during exercise.

What separates Fuel X Pro from FIXX's standard Fuel X formula is the addition of the amino acids alanine and leucine. Your 55g sachet contains 1,120mg alanine and 1,120mg leucine.

FIXX has deliberately created Fuel X Pro with a mild flavour and liquid sports-drink consistency, making it particularly suited to endurance events where athletes may be consuming nutrition for several hours and want to minimise flavour fatigue. FIXX describes the formula as all-natural, gut-friendly and designed for training and racing.

Carbohydrate & energy

Each 55g sachet provides 47.6g carbohydrate and 200 calories.

The carbohydrate base uses dextrose (glucose) and sucrose, providing an easy way to add substantial carbohydrate to your bottle rather than relying solely on gels or solid foods during longer sessions.

FIXX positions Fuel X Pro for athletes looking to stay fuelled and hydrated during endurance training and racing.

Electrolytes

Each sachet provides:

Sodium: 460mg
Potassium: 150mg
Calcium: 62mg
Magnesium: 24mg

This combination makes Fuel X Pro more than simply a carbohydrate drink — you're getting both fuel and electrolytes from the same bottle.

Amino acids

Fuel X Pro adds alanine and leucine to FIXX's endurance fuel formula.

Each 55g sachet contains:

Alanine: 1,120mg
Leucine: 1,120mg

FIXX specifically distinguishes the Pro formula by the inclusion of these performance-focused amino acids alongside its carbohydrate and electrolyte base.

Mild flavour for long sessions

One of the more useful features of Fuel X Pro is its deliberately mild taste.

FIXX developed the flavour profile with longer endurance sessions in mind, where repeatedly consuming strongly flavoured sports nutrition can contribute to flavour fatigue.

How to use

For the 55g single sachet:

1. Add the entire sachet to 500–700ml of water
2. Shake well to dissolve
3. Consume within 24 hours
4. Sip during exercise as required

FIXX's sachet instructions suggest sipping the prepared drink over approximately one hour during exercise, depending on your individual fuelling requirements.

Dextrose (glucose), sucrose, leucine amino acid, alanine amino acid, Australian sea salt, natural lemon lime flavour, sodium citrate, citric acid, potassium chloride, magnesium citrate, calcium carbonate.

Best suited for

Long runs, marathon and half-marathon training, trail and ultra running, cycling, triathlon, HYROX/endurance events and longer training sessions where you want carbohydrate, hydration and electrolytes together in your bottle.

True Stryde Tip: Fuel X Pro is a particularly useful option for runners who don't want to get all of their carbohydrate from gels. One bottle provides nearly 48g of carbohydrate plus electrolytes, and you can then layer gels or other fuel around it according to your individual race plan.
