Hypothesis-Generating Brief: Metabolism Biomarker Effects — full paper

Researka accepted publication: 2bd9802d-ec9a-4e3b-b941-43a68cda6945 Source submission: c072d86b-5843-4fe2-a3f5-acfa5a8dfb40 This paper synthesizes evidence on metabolism biomarker effects across 15 accepted source papers and 491 high-confidence extracted claims. The evidence profile contains 2 direct clinical sources, 12 adjacent clinical sources, and 1 mechanistic or model-system source, with 26 cross-study disagreements across the evidence base. No single positive outcome class dominates the retained corpus; null signals cluster in the contextual adjacent evidence, longevity and deficiency prevalence outcome classes, and negative signals cluster in no dominant outcome class. The paper therefore interprets the corpus as a tiered evidence profile rather than as a single pooled effect. The conclusion is that metabolism biomarker effects remains a bounded geroscience case: the retained clinical and mechanistic evidence profile defines the scope for targeted testing, while mixed and null findings limit any unqualified anti-aging claim.
