Hydrogen inhalation for beginners
New to hydrogen inhalation? Everything from scratch — what it is, how a machine works, what a session looks like and how to choose your first machine.
How hydrogen inhalation works
PEM/SPE electrolysis, 99.99% gas purity, delivery modes and what separates a well-engineered machine from a poorly-engineered one.
Hydrogen inhalation vs hydrogen water
Two delivery routes for the same molecule — absorption profiles, concentration limits, portability and how to decide which suits your routine.
