Saito 2018: H₂ and senior cognition

Paul Fournier

— WEEKLY EDITION · FRIDAY JUNE 19 —

H₂ and working memory after 65.

Saito et al. (2018, Aging Clinical Research) — 73 subjects aged 67-78, H₂-rich water at 9,600 PPB ±10% for 8 weeks.

Cross cognitive tests (MMSE, Trail Making Test B): +14% working memory performance, −18% reaction time vs placebo group.

Proposed mechanism: H₂ crosses the blood-brain barrier, selective neutralization of cerebral OH• radicals (the most toxic to neurons).

Honest limitation: Japanese study not replicated in Europe. But 9,600 PPB ± exceeds the ELITE 9K threshold (9,000 PPB), so accessible reproducibility.

+14% Working memory · −18% Reaction time · 73 Subjects 65-78
