The right amino acids at the right time™
Next-generation hydration is almost here. Be the first to know when HeatDefense™ launches.
Activates up to eight electrolyte transporters at once, compared to two for glucose-based drinks and zero for water. The result: up to 50% greater water and electrolyte absorption, with zero grams of sugar.*
Absorption is only half the battle. Rising core temperature stresses the gut, and a stressed gut hurts performance. HydroActive Technology™ helps protect your gut, too.*‡
HeatDefense™ delivers the right amino acids at the right time™ – for the moments when quitting isn’t an option.
More Transporters. More Hydration.
More Protection. Better Performance.
