Description

NEUROGEN H2® delivers molecular hydrogen directly to your cells — supporting cognitive clarity, natural energy, and whole-body antioxidant protection.
 

Drop one tablet into a glass of water, watch it dissolve, and drink within 20 minutes. That's it. No capsules, no powders, no complicated routines.
 

Molecular hydrogen is the smallest molecule in existence. It crosses the blood-brain barrier — something most supplements can never do — and selectively neutralises the most harmful free radicals in your body without affecting the beneficial ones.
 

30 effervescent tablets. 30-day supply.

Why you need NEUROGEN H2?

Your body was designed to produce molecular hydrogen naturally — generated by gut bacteria as part of your cellular repair system.
 

Modern life disrupts that process. Poor diet, stress, and environmental factors deplete the gut bacteria responsible for H2 production. 

When production drops, oxidative damage accumulates — particularly in the brain, where it shows up as fog, fatigue, and that feeling of not quite being yourself.
 

NEUROGEN H2® restores what your body has lost the ability to produce on its own.

Benefits

Supports cognitive clarity and mental focus

Promotes natural, sustained cellular energy

Provides selective antioxidant protection at the cellular level

Crosses the blood-brain barrier directly

Supports mitochondrial function

No stimulants, no crash, no complexity

Recommended Use

Drop one tablet into 8–12oz of water. Drink within 20 minutes as it dissolves.

Take daily for best results. 

Can be taken any time of day.

The Science Behind NEUROGEN H2®

The Science Behind 
NEUROGEN H2®

Molecular Hydrogen (H₂)

Each tablet dissolves in water releasing molecular hydrogen at 12PPM. The smallest molecule in existence — reaching cells and tissues no other antioxidant can physically access.

Selective Antioxidant Action

Unlike vitamin C or turmeric, hydrogen only targets hydroxyl radicals and peroxynitrite — the two most destructive species — leaving beneficial free radicals completely intact.

Mitochondrial Restoration

Hydroxyl radicals disrupt mitochondrial energy production. Molecular hydrogen penetrates the mitochondrial membrane directly, neutralising the damage at its source.

Blood-Brain Barrier Penetration

Most antioxidants can't enter the brain. Molecular hydrogen crosses the blood-brain barrier — reaching the neurons where oxidative stress drives cognitive fog.
