In this episode Dr. G explores molecular hydrogen (H2) — the smallest molecule with surprising biological effects — and how its selective antioxidant and anti-inflammatory actions might improve wound healing in diabetic foot ulcers.

We review the mechanisms, delivery methods, preclinical and emerging clinical evidence, and practical limits: H2 shows promise as an adjunctive redox modulator but is not a replacement for standard care like debridement, offloading, infection control, and vascular assessment.
