Designed to support you during your endurance workouts, Ultra Gummies combine 32 g of carbohydrates with 3 essential electrolytes. Their gel-like, melt-in-your-mouth texture is easy to chew and remains pleasant to eat even after several hours of exercise. Since they can be broken off one gum at a time, they fit seamlessly into your nutrition strategy—either on their own or alternated with OVERSTIMS gels, purees, and bars.
Unwavering energy and endurance
Co-developed with four-time UTMB champion François d’Haene, Ultra Gummies provide 32 g of carbohydrates (per 4-gummy pack) to support your endurance efforts.
Their formula also combines three essential electrolytes (sodium, calcium, and magnesium) to support your body during long-duration exercise and help replenish losses from sweating.
Designed for the demands of prolonged exertion, Ultra Gummies are formulated to ensure excellent digestive tolerance.
Unmatched effectiveness, designed to keep you going from the first to the last kilometer!
A soft, melt-in-your-mouth texture for a variety of tastes
After several hours of exertion, gels or bars can become difficult to consume. Ultra Gummies offer a real alternative thanks to their gel-like, soft, and melt-in-your-mouth texture.
Easy to chew: even during high-intensity activity, they can be consumed effortlessly.
Enjoyment preserved: they prevent nausea so that eating remains a real pleasure, even after several hours of running.
Spaced-out consumption to manage your energy strategy
Thanks to their convenient packaging—a packet of 4 individual gummies—you can space out your intake as needed, one gummy at a time, at regular intervals, depending on the intensity and duration of your workout.
To optimize absorption, take one or two sips of Hydrixir Ultra energy drink after each dose.
For the most demanding moments, the caffeinated versions—available only in Cola and Lemon-Ginger flavors—provide 80 mg of caffeine per 4-gum packet.
How and when should you consume Ultra Gummies?
Ultra Gummies should be consumed during exercise:
Target of 60 g of carbohydrates per hour: consume 4 Ultra Gummies—or 1 full packet—along with 500 ml of Hydrixir Ultra energy drink over the same period.
More advanced nutritional strategy of 90g of carbohydrates per hour: consume 8 Ultra Gummies—or 2 packets—along with 500 ml of Hydrixir Ultra per hour.
Depending on your preferences, you can also alternate the Ultra Gummies with OVERSTIMS gels, bars, or purees to vary the textures and prevent taste fatigue during prolonged exertion.
How does the collaboration with François d’Haene make a difference with these gummies?
Who better than an ultra-endurance icon to design the perfect gum? François d’Haene brought all his ultra-endurance experience to bear on the co-development of the Ultra Gums.
His goal was clear: to design a high-performance energy solution that’s easy to consume on the go, with a texture that’s pleasant to chew even during intense moments, and a formula designed to support the longest efforts.
Tested under the most demanding conditions, Ultra Gummies will see you through to the end of your challenges.
