Frequently Asked Questions
We love feedback! Please submit all feedback and suggestions via our form on the Contact Page. Your input is invaluable in helping us improve our products and services.
Our energy gel is crafted with a precise blend of carbohydrates, electrolytes, and hydration agents that work in harmony to:
- Fuel your muscles: Quick-acting carbohydrates provide immediate energy when needed.
- Enhance hydration: Essential electrolytes maintain fluid balance.
- Support recovery: A balanced formulation helps replenish glycogen and aids in post-exercise recovery.
- Steady release system: Endorsed by leading sports scientists, our gel delivers a continuous release of energy for sustained performance.
Carbohydrates are the primary fuel source for your body, especially during high-intensity exercise.
Here’s why they are essential for peak performance:
- Your immediate energy source is blood glucose, which your muscles rapidly use to provide the energy needed.
- Glycogen Storage: Glucose is stored in your muscles and liver as glycogen. These glycogen stores act as a readily available reserve that your body taps into during prolonged or intense exercise, helping to delay fatigue.
- Enhanced Endurance: Maintaining adequate carbohydrate levels ensures your muscles have the sustained energy required to perform at high intensities for longer durations. This is critical for endurance events where constant energy delivery is key.
- Optimal Brain Function: Carbohydrates also fuel your brain, supporting cognitive functions such as focus, coordination, and decision-making, which are crucial during competitive performance.
- Efficient Recovery: Consuming carbohydrates before, during, and after exercise helps replenish glycogen stores, accelerating recovery and preparing for subsequent training sessions or competitions.
- Water: Filtered and purified for essential hydration.
- Maltodextrin: A long chain of glucose molecules rapidly broken down and absorbed (via SGLT1) for immediate energy.
- Fructose: A natural sugar from fruit, absorbed via GLUT5, which complements maltodextrin and supports liver glycogen restoration.
- Coconut Water Powder: Provides electrolytes and essential vitamins/minerals for hydration and overall health.
- Himalayan Salt: Supplies essential sodium to maintain fluid balance during exercise.
- Tri Magnesium Citrate: A highly bioavailable form of magnesium in a triple citrate formulation, offering enhanced solubility and absorption to help prevent cramps and support overall performance.
- Potassium Sorbate: An antimicrobial agent that extends shelf life by preventing mould, yeast, and bacteria.
The performance gel results from a unique collaboration between top athletes and experts. It was co-designed by Olympic champion Alistair Brownlee and Nigel Mitchell, alongside renowned academics and a network of dedicated co-creators. With decades of experience, the latest research, extensive lab work, and rigorous field testing, we’ve crafted the ultimate performance gel to fuel your endurance and elevate your game.
Sodium is essential for maintaining fluid balance, nerve function, and muscle contraction. It helps prevent cramps and fatigue, making it a key component in any performance nutrition plan.
