B.4.T Fuel - Isotonic
B.4.T FUEL is PHN’s signature isotonic drink — a clean, high-performance blend of Cluster Dextrin® carbohydrates and essential electrolytes. Engineered to deliver smooth energy, fast hydration, and sustained performance for every athlete.
Many sports drinks deliver energy — but often with downsides: sudden spikes and crashes, or digestive discomfort during training and competition. These issues are familiar to athletes at every level, and they can be the difference between finishing strong or falling short. At PHN, we set out to remove these barriers and create a formula that works as hard as you do. That’s why we built B.4.T Fuel around Cluster Dextrin® (highly branched cyclic dextrin), a new-generation carbohydrate engineered for performance. Its unique structure ensures rapid absorption, steady release of energy, and exceptional gastric tolerance — even under the most demanding conditions. No sudden drops, no stomach distress — just clean, reliable fuel that supports both endurance and intensity. To complete the formula, we added essential electrolytes — sodium, magnesium, chloride, calcium, and potassium — to keep hydration, muscle function, and nerve signaling at peak levels. Together, they help delay fatigue, maintain focus, and sustain output over time. Developed and tested by athletes, produced in Switzerland under FSSC 22000 certification, B.4.T Fuel reflects the PHN philosophy: premium nutrition designed to eliminate obstacles and let true performance shine.
1–3 servings per day, depending on training duration, environmental conditions, and individual sweat rate.
Mix 2 level scoops (approx. 52 g of carbs) of B.4.T Fuel with 750 ml of water, every hour.
Cluster Dextrin®
Cluster Dextrin® (highly branched cyclic dextrin) is a new-generation carbohydrate created through advanced enzymatic technology. Unlike traditional sugars such as maltodextrin, sucrose, or fructose, which can cause rapid spikes in blood sugar, sudden drops in energy, or digestive discomfort, Cluster Dextrin® has a unique ring-shaped molecular structure. This structure gives it a dual advantage: it moves quickly through the stomach for fast gastric emptying, while releasing energy in a smooth and sustained way. The result is fuel that supports performance without bloating, cramps, or the heavy stomach many athletes experience with conventional sports drinks. Studies have shown that Cluster Dextrin® improves endurance, reduces fatigue, and provides consistent energy supply even under prolonged or high-intensity exercise. In simple terms, it fuels like a simple carbohydrate but sustains like a complex one — without the downsides. That's why PHN made Cluster Dextrin® the foundation of B.4.T Fuel: a premium isotonic drink designed to deliver clean energy, optimal hydration, and performance without compromise.
Electrolytes
Electrolytes are essential minerals that keep the body in balance during exercise. When you train, you lose sodium, chloride, magnesium, calcium, and potassium through sweat — and without replenishment, performance drops. Muscles cramp, fatigue sets in, and focus fades. That's why B.4.T Fuel combines five key electrolytes in its formula. Sodium and chloride work together to maintain hydration, fluid balance, and blood volume. Magnesium supports energy production and helps prevent cramps, calcium enables proper muscle contraction, and potassium regulates nerve function and fluid distribution. Together, they ensure that hydration isn't just about replacing water — it's about keeping the body performing at its peak, even under pressure.
Clean Taste
B.4.T Fuel is not just about performance — it's about clean, transparent nutrition. That's why the formula is free from sugars. Instead, it is lightly sweetened with steviol glycoside (from stevia), a plant-based alternative that provides natural sweetness without calories, sugar spikes, or artificial aftertaste. Flavoured only with natural ingredients such as beetroot juice and paprika extract, B.4.T Fuel delivers a refreshing taste while remaining light and easy to digest. A product you can trust — clean fuel, built without shortcuts.
