The molecule
H2 is essentially inert and only reacts in the specific contexts described in the literature. It has no taste or smell.

Molecular hydrogen (H2): what is it?
Molecular hydrogen is two hydrogen atoms paired — nature's smallest and lightest molecule. The size is the point: H2 diffuses quickly, and researchers study its role in oxidative balance and cellular signaling. Here are the basics, without the hype.
The basics
A small molecule, a growing research field.
The field
Since a landmark 2007 study in Nature Medicine, the field has grown: studies and reviews exist in areas such as oxidative stress and exercise recovery. See our reading list with PubMed links.
The evidence
Promising but not sufficient for clinical recommendations. It is education — not product promises.
In Japan
Hydrogen is used more broadly in Japan, including in clinical settings. That says nothing about how it may be presented in the EU, where hydrogen is not an approved treatment.
The formats
Three ways to take H2.
Inhalation
Low, controlled-concentration hydrogen inhaled during a focused session — the more concentrated format. About hydrogen inhalation.
Hydrogen water
Hydrogen dissolved in drinking water — quick and flexible; freshness decides. Hydrogen water guide.
Tablets
Effervescent tablets generating hydrogen in the water on the spot. An easy entry point, same freshness logic.
