The Science of Performance & Recovery: Fuelling Your Potential.

Every rep, every mile, every session pushes your body.

To truly unlock your potential, it's not just about how hard you train, but how intelligently you fuel and recover. At DuelFuel, we believe in the power of science-backed nutrition to elevate your game.

Why Science Matters for Your Gains.

Your body is an incredibly complex machine. Just like a high-performance engine needs the right kind of fuel and maintenance, your muscles and systems demand precise nutrition to perform, adapt, and grow stronger. Neglecting this crucial aspect can lead to fatigue, compromised performance, slow recovery, and even injury.

The Science of Fuelling Your Performance.

Before you even step into the gym, hit the road or head out for a walk, your body needs readily available energy. This is where carbohydrates come in. They are your primary fuel source, directly impacting your stamina, strength, and focus [1, 2]

Glucose is King

When you consume carbohydrates, your body breaks them down into glucose, which is stored as glycogen in your muscles and liver. During exercise, this glycogen is converted back into glucose, providing the energy your muscles need to contract and perform [1].

Sustained Release is Key

For longer or more intense sessions, you need a steady supply of energy, not a quick spike and crash. This requires strategically chosen carbohydrates that release glucose gradually.

How DuelFuel's Flapjack Fuels You.

Our Peanut Butter & Chocolate Flapjack is engineered for this exact purpose. With 19.7g of carbohydrates, it provides accessible energy to power your workout, without feeling heavy. Its balanced composition of simple and complex carbohydrates ensures a sustained release, helping you maintain intensity from start to finish.

The Science of Optimal Recovery Post-Workout.

The magic of muscle growth and adaptation happens after your exercise or activity, during recovery. This critical window requires two main components: protein and carbohydrates [3, 4].

Protein for Repair & Growth

Exercise causes microscopic tears in muscle fibres. Protein provides the amino acids, the building blocks your body needs to repair these tears, leading to stronger, more resilient muscles. Rapid protein intake post-exercise maximises this repair process [3].

Carbohydrates for Replenishment

After intense activity, your muscle glycogen stores are depleted. Consuming carbohydrates post-workout helps to quickly replenish these stores, preparing your muscles for the next session and preventing fatigue [1, 4].

How DuelFuel's Brownie Powers Your Recovery.

Our Chocolate Brownie is your recovery powerhouse. With an impressive 16.3g of protein, it delivers essential amino acids precisely when your muscles need them most. Combined with its 7.5g of carbohydrates, it efficiently kickstarts glycogen replenishment, accelerating your recovery so you're ready to perform again.

Beyond Macros: The Vital Role of Micronutrients.

While carbohydrates, proteins, and fats (macros) are fundamental, the supporting cast of vitamins and minerals (micros) is equally critical. These are the unsung heroes involved in countless metabolic processes that turn food into energy, build muscle, support immunity, and protect your cells [5, 6].

Energy
Production:

B vitamins are essential co-factors in converting food into usable energy [6].

Muscle
Function:

Minerals like Magnesium and Calcium are vital for muscle contraction and nerve transmission [5].

Immune
Support:

Vitamins A, C, D, E, and minerals like Zinc and Selenium play key roles in keeping your immune system robust [6].

Bone
Health:

Calcium, Phosphorus, and Vitamin D are foundational for strong bones, crucial for impact sports and heavy lifting [5].

How DuelFuel Provides Comprehensive Support.

DuelFuel goes beyond basic fuelling. Our combined 75g DuelPack contains a bespoke blend of 26 essential vitamins and minerals, containing between 17 -20% of the reference intake*. This comprehensive approach helps prevent deficiencies that can hinder performance and recovery.

*Reference Intake (RI) is a clear guideline established by EU legislation (Regulation 1169/2011), based on scientific advice from the European Food Safety Authority (EFSA), showing you how much DuelFuel contributes to your daily nutrient needs, helping you intelligently fuel your body for peak performance and optimal health.

The Gut: Your Unsung Hero of Performance.

Increasingly, science highlights the profound connection between gut health and overall well-being, including athletic performance. A healthy gut efficiently absorbs nutrients and helps manage inflammation [7, 8].

Nutrient Absorption

A compromised gut can lead to malabsorption, meaning you're not getting the full benefit from the food you eat, even if your diet is otherwise good [7].

Digestive Comfort

For physically active people, digestive issues during training or competition can be debilitating, impacting focus and physical output. Certain ingredients, like polyols*, are notorious for triggering these problems [9, 10].

*What are Polyols (and why DuelFuel doesn’t use them)?
Polyols, often known as sugar alcohols (like maltitol, xylitol, or sorbitol), are a common sugar substitute found in many "diet" or "low-sugar" foods, including some sports bars. While they can sweeten products without adding many calories, many polyols come with a significant downside for active individuals:

  • The Gut-Grumble Culprit: Your body doesn't fully absorb polyols. This means they can ferment in your gut, leading to uncomfortable symptoms like bloating, gas, and digestive distress – issues no athlete wants to experience during a workout or competition.
  • DuelFuel's Solution: We designed DuelFuel for your performance and comfort. DuelFuel does contain a polyol – glycerine, however glycerine is gut-friendly because it is very well absorbed in the small intestine, unlike many other polyols that often cause issues in sensitive individuals due to malabsorption [10]. Our aim is to provide you with clean, effective fuel that powers your training and recovery without causing any digestive discomfort. You get the great taste and optimal nutrition, without the unwanted side effects.

With DuelFuel, you can focus on pushing your limits, not on your stomach.

How DuelFuel Supports Your Gut Health.

We specifically formulated DuelFuel to be low in polyols (See section above on DIGESTIVE COMFORT). This deliberate choice minimises the risk of digestive discomfort, such as bloating and gas, commonly associated with sugar alcohols found in many other bars [9, 10]. By providing a gut-friendly fuelling option, DuelFuel ensures you can absorb the nutrients effectively and perform without distraction.
