HydroMax™ is the a concentrated—65 percent—yet stable form of powdered glycerol offering hydration in a proprietary blend of glycerol and silica. GMS powders are 5 percent to 12 percent potent and become unstable as it absorbs water. HydroMax™ is easily absorbed and distributed throughout the intracellular space, increasing the concentration of fluid in the blood and tissues. This brings possible benefits for endurance and stamina events, such as adaption to the environmental stress and promoting blood flow associated with resistance training. It’s also been shown to help athletes store extra water for the purpose of rehydrating after intense exercise.
