Keira D'Amato is one of the most accomplished women's distance runners in the United States, and currently holds the American Women's Half-Marathon and 10-Mile Record. Keira made the switch to UCAN last year, after testing out the products extensively while training for the New York City Marathon. UCAN products contain LIVSTEADY, a steady-release, complex carbohydrate that maintains stable blood sugar and steady energy levels for hours, without the spike & crash of sugar-based fuels.

The blood sugar rollercoaster: how sugar-based gels let you down.

Spike and crash effect
Standard energy gels rely on sugar or fast carbs, leading to quick spikes and inevitable crashes in blood sugar, causing inconsistent energy and frequent refueling.

The better solution
UCAN's patented carbohydrate, LIVSTEADY, releases energy gradually, supporting sustained performance without the ups and downs of sugar spikes.

Less sugar, less stomach trouble.

Traditional gels lead to digestive distress
With sugar-based gels, athletes are instructed to consume a large amount of sugar during a race, which can cause stomach issues.

Fewer gels needed = more comfort and less hassle

Simplified fueling strategy
UCAN's efficient formula means athletes can use fewer gels over the cours of a race, providing a simpler, more effective fueling strategy.

“With UCAN Edge, I’ve felt so much better throughout the runs compared to taking other gels, where I would feel this burst of energy, but then it would be so short-lived.”
