A science-based formula
Elixyr Endurance Fuel is built on Highly Branched Cyclic Dextrin (HBCD), a fast-digesting, low-osmolality carbohydrate, combined with a 2:1 glucose-to-fructose ratio. This ratio allows you to absorb up to 120 g of carbs per hour, well beyond the ~60 g of single-sugar formulas — a key advantage on efforts longer than 90 minutes.
Carbs and electrolytes in a single product
Each serving delivers 30 g of carbohydrates (120 kcal) and a 500 mg electrolyte complex, including 340-350 mg of sodium, plus potassium, magnesium and calcium. Enough to support energy and hydration without juggling multiple products. To round things out, explore our energy drinks and electrolytes.
How to use Endurance Fuel
Mix one serving with about 500 ml of water and drink before and during your effort based on intensity and duration. For long outings, aim for 60 to 120 g of carbs per hour by combining the drink with energy gels and chews or energy bars according to your taste and digestion preferences.
Three flavours, easy to carry
Elixyr Endurance Fuel comes in Tropical Passion, Watermelon-Lime and Peach-Mango, in a 25-serving bag. Carry it on your runs with our hydration accessories (flasks, belts and vests).
Why choose Elixyr
A clean, digestible formula with no phantom ingredients, a higher carbohydrate density and a price far more accessible than the competition. Ideal for building a simple, effective nutrition strategy for your training and races.
