Evidence status M3: The slug names liver and metabolism. This article treats both only as research terms. It explains measurements and study design without drawing a conclusion about people, health or products.
Measurements belong in a study plan
Evidence status M3: For metabolomic data, the Metabolomics Standards Initiative: Sumner et al. (2007) sets out details on samples, analysis and data processing. This reporting framework explains what is needed to interpret a measurement. It is not H₂ evidence or a statement about use.
H1: The suitable human source is missing
Evidence status H1: A statement about people would require a verified H₂ primary study with a population, comparator and prespecified metabolism endpoint. This article does not document such a suitable source. The H1 question therefore remains an evidence gap.
L2 stays separate from people
Evidence status L2: Cell or animal models would need to be named as such and could not replace a human research question. This article transfers no laboratory or animal finding to people. Read microbiome studies in context for a neighbouring measurement field.
N: No conclusion for everyday use
Evidence status N: Without a suitable primary source, this article makes no statement about the liver, blood sugar, detoxification, amount or product use. The molecular-hydrogen pillar explains the evidence levels. Review sports studies and endpoints and compare primary studies keep the research questions separate.
Conclusion
Evidence status N: A broad term does not replace a suitable study. Source, population, comparator, endpoint and the stated evidence gap remain decisive.
