Antioxidant Water Enhancer
12 PPM
H2TAB delivers a powerful punch with the highest concentration of 12 ppm nano-bubbles.

Small, Yet Powerful
As the smallest, lightest and most abundant element in the universe, hydrogen can easily penetrate deep into tissues and pass through cell membranes. The high bioavailability and antioxidant properties of hydrogen-rich water have been studied for their potential to support cellular health, cognitive function, physical performance and recovery by facilitating faster absorption at the cellular level.

Anywhere. Any time. Hydration like no other.
By incorporating hydrogen-rich water into your daily routine, you have the power to promote hydration within your cells so they can work at their full potential to support your body’s cellular, metabolic, gut and cognitive health. Since your body creates the most free radicals during workouts, maximize the effectiveness of H2Tab by drinking your hydrogen water before, during or after workouts and amp up your body’s antioxidant activity.
