ZYM will be unveiling their new flavor called Rival at Interbike.

With an Orange flavor, it has a couple of things to set it apart. First, it has no sugar and uses stevia to sweeten it. Second, it uses Rhodiola Rosea, an herb that purportedly boosts energy and reduces fatigue.

“Unlike other similar drink tabs, ZYM RIVAL is the first and only portable, naturally sweetened sports drink,” owner Brian Koff says. “Made from premium ingredients, RIVAL provides athletes with natural energy, fresh legs and enhanced performance. And its light, refreshing orange flavor quenches an athlete’s thirst with a clean finish and no sugary residue.”

RIVAL also contains essential electrolytes to maintain adequate hydration plus added vitamins.

UPDATE: It’s delicious.
