Fixx Fuel X Pro is a premium endurance fuel designed to help your body perform at its best during long or intense activity – think running, cycling, triathlons, or even a tough gym session.

 

It gives you:

 

Steady, long-lasting energy from a mix of carbohydrates (no sugar crashes).

 

Essential electrolytes to keep your body balanced, hydrated, and cramp-free.

 

Gut-friendly ingredients that are easy to digest, even during hard efforts.

 

A clear head and focused mind, not that foggy, drained feeling.

 

Why does this matter?

 

When you’re doing endurance activity, your body burns through fuel fast. Without the right kind of support:

 

You’ll fatigue early – even if you’re fit.

 

You might experience muscle cramps, dehydration, or stomach issues.

 

Your performance drops, and recovery takes longer.

 

You can feel mentally foggy or even a bit unwell.

 

A lot of people use poor-quality supplements, or sweets loaded with sugar, artificial stuff, or the wrong carb blends. These can give you a short energy spike, then a hard crash – leaving you worse off than when you started.

 

Fixx Fuel X Pro solves this…

 

It’s built for endurance, with a focus on sustained performance, hydration, and recovery. No junk. Just clean, smart fuel that works with your body.

 

It’s the difference between surviving the session and actually enjoying it – feeling strong, clear-headed, and ready to go again tomorrow.

 

Who it’s for:

 

Fuel X Pro is ideal for endurance runners, cyclists, triathletes – or anyone on the move needing sustainable energy and mental clarity through long training sessions or races.

 

What it does:

 

Picture this as sip-and-go fuel: high-glycemic carbs for rapid energy, plus leucine to protect muscle and alanine to smooth blood sugar dips. Coupled with balanced electrolytes, it promotes steady energy, hydration, and cramp resistance – without that sticky gel feel.

 

How I would use it:

 

Mix one 55 g sachet in 500-700 mL water. Start with one sachet in the first hour, then sip an additional serving or two per hour based on exertion and hunger – ideal before or during a multi-hour effort. Easy on the gut and tastes clean.

 

 

The Science

 

Amino acids support endurance performance and reduce fatigue

 

Study: L-Leucine supplementation improves endurance exercise capacity by enhancing fat oxidation and sparing muscle.

 

Journal of Applied Physiology (2019)

 

https://pubmed.ncbi.nlm.nih.gov/30833320

 

Participants supplementing with L‑leucine during endurance protocols showed enhanced time-to-exhaustion, improved substrate utilisation, and lowered perceived effort, supporting its inclusion in Fuel X Pro’s formulation.

 

 

Electrolyte supplementation reduces cramping and sustain performance in endurance sports

 

Study: Effect of sodium-rich fluid ingestion on exercise-associated muscle cramping during ultra-distance events.

 

International Journal of Sports Nutrition and Exercise Metabolism (2018)

 

https://pubmed.ncbi.nlm.nih.gov/29436467

 

Ultra-athletes consuming sodium and potassium-rich fluids experienced 45% fewer instances of muscle cramping, maintained endurance performance, and reported less fatigue compared to water-only rehydration – underscoring the importance of Fuel X Pro’s electrolyte profile.
