Level 5 - mechanism / opinion, no new human data
Narrative review of mechanisms, delivery methods, and therapeutic applications without systematic synthesis or primary clinical trial data.

What was done
This narrative review synthesized literature on molecular hydrogen (H2), focusing on its biological mechanisms, administration routes (exogenous administration and endogenous production by gut microbiota), and therapeutic applications in intestinal disorders (such as inflammatory bowel disease, ischemia-reperfusion injury, and colorectal cancer) and other conditions, alongside delivery strategies including nanoplatforms.
What was found
The abstract reports no numerical data, effect estimates, or statistical findings. It conceptually notes that hydrogen efficacy depends on administration route, contact time, and target concentration, and suggests nanoplatforms and microbiome interactions as potential avenues to optimize therapeutic delivery.
Why it matters
It provides a conceptual overview of molecular hydrogen delivery challenges and mechanistic rationales, highlighting potential interfaces between gas therapy and nanomedicine.
Limits
As a narrative review, the paper presents no new human experimental data, quantitative synthesis, or systematic search protocol. Details on sample sizes, clinical efficacy in humans, safety endpoints, and comparative effect sizes are absent from the abstract.
