Ben Greenfield interviews water researcher Robert Slovak (podcast date 2020-06-04) about molecular hydrogen (H2): history, mechanisms, delivery formats, dosing, testing and product considerations. Key scientific points: H2 acts as a selective antioxidant/modulator of redox signaling (targets hydroxyl/peroxyl radicals), influences NRF2 and NF‑κB pathways, can affect autophagy and PGC‑1α (mitochondrial biogenesis), and has broad investigational uses (metabolic syndrome, ischemia–reperfusion, inflammatory/cardiac/neurologic contexts). Delivery methods covered: electrolysis/alkaline ionizers (variable 0.3–1.5 ppm), tablets (magnesium-based; early ~1.5 ppm to modern higher ppm; tablet masses discussed), portable generators, proton-exchange membrane devices (~2–4 ppm, costly), inhalation (clinical use; specific flow rates), IV H2‑rich saline, canned/pouched ready-to-drink products (cans preferred), and transdermal/baths/eyedrops as niche uses. Testing method: H2 Blue methylene-blue titration (each drop ≈0.1 ppm). Practical guidance: consume packaged H2 quickly after opening; tablets produce microbubbles and are more stable; common personal dosing is morning and evening (Robert: four tablets/day). Product/manufacturing notes: tablet production is complex; common tablet excipients minimal (small binder, organic acid, lubricant, flavor), and most tablets contain elemental magnesium as the H2 source. The podcast includes anecdotal clinical and personal testimonials but avoids medical claims; inhalation and IV are described as clinical modalities.

Questions this episode answers

About 1.6 parts per million (ppm).

Using a methylene blue titration kit (H2 Blue); each drop equals 0.1 ppm hydrogen.

Alkaline ionizers: ~0.3–1.5 ppm (many <0.5); tablets: early ~1.5 ppm up to modern 6–10+ ppm depending on tablet and water volume; proton-exchange appliances: ~2–4 ppm; cans/pouches: 2–8 ppm when properly packaged.

Early tablets ~30 mg Mg, modern up to ~80 mg Mg per tablet; approximate mass ratio ~12:1 (Mg mass to hydrogen mass).

He stated he takes four tablets per day, two at a time in ~10 oz (≈300 mL) water, which he said produced concentrations >10 ppm in that context.
