Enjoy a bath that does more with H2Tab’s Hydrogen Bath Tablets. Each tablet releases billions of tiny bubbles, creating a gentle, science-inspired soak.

Formulated with magnesium, these tablets help reduce tiredness and fatigue and support normal muscle function—perfect for unwinding after exercise or a long day.

The blend is designed to leave your skin feeling calm and refreshed, turning your bath into a moment of pure relaxation. Whether you’re looking to recover, relax, or simply recharge, Hydrogen Bath Tablets bring a little extra care to your daily routine.

Unlike typical bath soaks that rely on surface-level minerals or essential oils, Hydrogen Bath Tablets use molecular hydrogen to deliver benefits beneath the surface. This form of hydrogen is a powerful antioxidant that penetrates the skin and works at a cellular level. It helps neutralise oxidative stress, supports circulation, and encourages faster recovery. By using molecular science instead of conventional ingredients, this soak offers deeper support for both skin and body. You can feel the difference as your body relaxes, repairs, and recharges after each bath.

Founded by endurance athlete Cole Brecka, longevity expert Gary Brecka, and designer Megan Barrett, H2Tab was created to bring the transformative benefits of hydrogen water to everyone. As the first company dedicated exclusively to hydrogen tablets, H2Tab makes molecular hydrogen accessible in its purest, most bioavailable form and in a way that is easy to integrate into your daily life..

01/ Fill your tub or basin with water. For full-body soaks, use a standard bathtub. For targeted recovery, a smaller basin works great.

02/ Add 1 bath tablet for every 5 gallons of water (this is around 15-20 tablets for a standard tub). 


03/ Let the tablet(s) fully dissolve before submerging.

04/ Soak for 15-20 minutes for optimal benefits.

+ Do not ingest tablets.


+ Store in a cool, dry place at room temperature.

For best results, we recommend using warm water. Cold water will still generate hydrogen—the tablet may just take a bit longer to fully dissolve. We don’t recommend extremely hot water, as it can cause the hydrogen to dissipate more quickly, reducing its effectiveness.
