Atmosphere, Gas & Pressure
Molecular Hydrogen Inhalation
Route inhaledInvasiveness non-invasiveDirection additive
Inhaled molecular hydrogen (H2) as the carrier; a redox-mitochondrial selectivity is the vendor claim, with thin human outcome data.
Origin & lineage
Consumer H2 inhalers / longevity clinics.
Claimed mechanism
Inhaled H2 is claimed to act as a selective antioxidant / mitochondrial-redox modulator.
Plausibility
Plausible–weak; inhaled gas is a real dosable carrier, but the selective-antioxidant human outcome evidence is thin.
Evidence — grade C/D
Inhaled gas is the carrier; the redox-mitochondrial selectivity is a vendor claim and human outcome data are thin.
Market
Makers: Ammortal; longevity-institute and others.
Models: H2 inhalers.
Price: Consumer.
Kernel — keep vs set aside
Keep — real substrate
A real, dosable inhaled gas.
Set aside — claim
Selective-antioxidant / longevity benefit is a vendor claim, not established in human outcomes.
Regulatory status by jurisdiction
Registration or clearance is a market-access fact, never proof of efficacy.
