The paper therefore interprets the corpus as a tiered evidence profile rather than as a single pooled effect.\n\nThe conclusion is that Taurine supplementation 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.\n\n## Methods\n\n### Review type and protocol\nThis manuscript is reported as a Thin-corpus evidence brief. A deterministic protocol governed source retrieval, screening, extraction, and synthesis; the protocol was frozen before manuscript rendering. The full audit trail is in the supplementary `methods_pack.json` and the timestamped submission directory `synthesis-taurine-v06-DAILY-2026-06-24T08-14-59Z`.\n\n### Information sources\nSources were retrieved across PubMed, Europe PMC, OpenAlex, Semantic Scholar, Crossref, DOAJ, OpenAIRE, PMC OAI, bioRxiv, medRxiv, arXiv, and ClinicalTrials.gov. Retrieval window: 2026-06-24.\n\n### Search strategy\nThe following topic-anchored queries were executed against the information sources listed above:\n\n- `taurine AND aging AND human`\n- `taurine supplementation AND randomized trial`\n- `taurine AND older adults AND muscle`\n- `taurine AND cardiovascular AND meta-analysis`\n- `taurine deficiency AND aging`\n- `taurine AND lifespan AND mammals`\n- `taurine AND blood pressure AND randomized`\n- `taurine abundance AND mortality AND cohort`\n- `taurine deficiency AND aging AND human cohort`\n- `plasma taurine AND older adults AND mortality`\n- (... 2 additional queries; see `methods_pack.json` for the full list)\n\n### Eligibility criteria\n- Sources whose primary content addresses taurine.\n- Sources with extractable quantitative or qualitative findings.\n- Peer-reviewed primary research, systematic reviews, or meta-analyses; preprints accepted only when source-traceable.\n- Sources with verifiable bibliographic identifiers (DOI / PMID / canonical handle).\n\n### Selection of sources of evidence\nThe synthesis did not begin from an unfiltered database export. It began from a pre-curated receipt-candidate set generated by the retrieval and claim-binding pipeline. Of 1261 records in the receipt-candidate union, 1248 were classified as source candidates and 67 were admitted as traceable synthesis sources. Mixed partial-or-none and partial-only rows are separate claim-binding audit buckets, not additive exclusion totals. No additional records were excluded after final source admission.\n\n### source admission funnel\n\n| Admission bucket | n |\n|---|---:|\n| Receipt candidate union | 1261 |\n| Classified source candidates | 1248 |\n| No extractable claims | 26 |\n| None-only claim binding | 7 |\n| Mixed partial-or-none claim-binding candidates | 49 |\n| Partial-only claim-binding candidates | 22 |\n| Strict high-confidence sources | 16 |\n| Admitted final sources | 67 |\n\n### Exclusion reasons\n- No records were excluded at the gates instrumented for this run: the eligibility criteria above were applied during retrieval and claim-binding but produced no post-screening exclusions with recorded counts for this corpus.\n\n### Data items\nThe following fields were extracted from each included source: study design, population / cohort, intervention or exposure, comparator, outcome class, effect direction, effect size, confidence interval or credible interval, p-value, sample size, follow-up duration, risk-of-bias rating. Under the calibration rule, source verification in the public bundle is limited to reference-level metadata; exact statistics and effect directions are drawn from these structured extraction artifacts (the synthesis manifest, risk-of-bias sidecar when populated, and claim registry) rather than from re-parsed full text.\n\n### Risk-of-bias appraisal\nRisk-of-bias framework assignment follows study design (RoB-2 for RCTs, ROBINS-I for non-randomised studies, AMSTAR-2 for systematic reviews / meta-analyses). Public appraisal claims are limited to populated `risk_of_bias.json` rows; when no populated ratings are present, interpretation remains bounded by source tier and directness rather than formal RoB certification.\n\n### Synthesis approach\nEvidence-tension synthesis: claims grouped by outcome class (cardiometabolic, contextual adjacent evidence, deficiency prevalence, immune and inflammation, longevity, mechanism, mortality and survival, muscle function, safety and comorbidity); within-class agreement, disagreement, and directness gaps surfaced explicitly. Quantitative pooling applied only where ≥3 sources reported a comparable endpoint with extractable effect estimates.\n\n### AI-use disclosure\nSource retrieval, claim extraction, evidence routing, and prose drafting were assisted by large language models under a deterministic audit-trail protocol. Every manuscript claim is traceable to a source record in the supplementary `manifest.json`. Final eligibility and interpretation decisions are author-verified.\n\n### Accountability\nAccountability is established through reproducible artifacts: a deterministic protocol (`methods_pack.json`), a complete claim and citation registry, extracted numeric trace, deterministic gates (`full_paper.journal_surface.json`, `pre_submit_gate.json`, `artifact_consistency.json`), and a versioned correction path documented in the run's submission record. Certification under the `researka_agent_certified` model verifies that the manuscript is machine-verifiable, internally consistent, provenance-traced, and format-checked against these artifacts; it does not adjudicate domain correctness, corpus fit, or novelty, which remain subject to expert and reader review.\n\n## Results\n\n**Outcome-class note:** Contextual Adjacent Evidence denotes background, boundary-condition, or adjacent-outcome sources. It is not pooled with direct outcome evidence; these sources bound scope, safety, methods, and translation rather than serving as equal-weight support for the main efficacy claim.\n\n| Evidence domain | Corpus slice | Strongest signal | Directness | Main limitation |\n|---|---|---|---|---|\n| Contextual Adjacent Evidence | n=35; claims=1187 | no extracted directional signal in 27/35 sources | 3 direct; 14 indirect; 18 review | limited corpus depth in this outcome class |\n| Cardiometabolic | n=13; claims=321 | no extracted directional signal in 6/13 sources | 2 direct; 1 indirect; 10 review | limited corpus depth in this outcome class |\n| Immune and Inflammation | n=8; claims=123 | no extracted directional signal in 6/8 sources | 1 direct; 1 indirect; 6 review | limited corpus depth in this outcome class |\n| Muscle Function | n=4; claims=52 | no extracted directional signal in 3/4 sources | 1 indirect; 3 review | limited corpus depth in this outcome class |\n| Longevity | n=2; claims=9 | unclear signal in 2/2 sources | 1 direct; 1 review | limited corpus depth in this outcome class |\n| Mechanism | n=2; claims=45 | no extracted directional signal in 2/2 sources | 2 mechanistic | limited corpus depth in this outcome class |\n| Deficiency Prevalence | n=1; claims=13 | no extracted directional signal in 1/1 sources | 1 indirect | single-source slice; hypothesis-generating |\n| Mortality and Survival | n=1; claims=44 | mixed signal in 1/1 sources | 1 direct | single-source slice; hypothesis-generating |\n| Safety and Comorbidity | n=1; claims=33 | no extracted directional signal in 1/1 sources | 1 review | single-source slice; hypothesis-generating |\n\nThis evidence brief reports outcome packets as a map of retained evidence rather than as a full journal Results narrative or pooled effect estimate.\n\n### Contextual Adjacent Evidence Outcomes\n\n35 included sources were assigned to this outcome class. Directional coding: null=27, positive=8. Directness coding: direct=3, indirect=14, review=18.\n\n### Cardiometabolic Outcomes\n\n13 included sources were assigned to this outcome class. Directional coding: mixed=1, negative=3, null=6, positive=3. Directness coding: direct=2, indirect=1, review=10.\n\n### Immune Inflammation Outcomes\n\n5 included sources were assigned to this outcome class. Directional coding: null=4, positive=1. Directness coding: indirect=1, review=4.\n\n3 included sources were assigned to this outcome class. Directional coding: null=2, positive=1. Directness coding: direct=1, review=2.\n\nEvidence for this outcome class is represented in the structured results table, but the retained narrative paragraphs were more strongly assigned to adjacent outcome classes. The synthesis therefore treats this class as context for cross-domain interpretation rather than as a standalone prose claim.\n\n### Muscle Function Outcomes\n\n4 included sources were assigned to this outcome class. Directional coding: null=3, unclear=1. Directness coding: indirect=1, review=3.\n\n### Longevity Outcomes\n\n2 included sources were assigned to this outcome class. Directional coding: unclear=2. Directness coding: direct=1, review=1.\n\n### Mechanism Outcomes\n\n2 included sources were assigned to this outcome class. Directional coding: null=2. Directness coding: mechanistic=2.\n\n### Deficiency Prevalence Outcomes\n\n1 included source were assigned to this outcome class. Directional coding: null=1. Directness coding: indirect=1.\n\n### Mortality Survival Outcomes\n\n1 included source were assigned to this outcome class. Directional coding: mixed=1. Directness coding: direct=1.\n\n### Safety Comorbidity Outcomes\n\n1 included source were assigned to this outcome class. Directional coding: null=1. Directness coding: review=1.\n\n## Limitations\n\nSingle-source outcome classes (Deficiency Prevalence, Mortality and Survival, Safety and Comorbidity) are treated as hypothesis-generating and receive proportional narrative depth rather than standalone evidentiary weight.\n\n**Verification note:** Reference-only or no-abstract records are treated as verification-limited context, not as equal-weight support for the main claim.\n\nA first limitation is the absence of a long-term, adequately powered mortality or hard cardiovascular endpoint trial of taurine monotherapy in non-diabetic, community-dwelling adults. Consequently, the headline conclusion that the anti-aging case is 'incomplete' rests on the absence of such a trial as much as on the heterogeneity of the surrogate-level data, and any inference about long-term clinical benefit cannot be supported by the present evidence map.\n\nA second limitation is single-source dependence for several outcome classes that nevertheless appear in the synthesis. The Longevity class is supported only by Mottaghi 2026 (liver-transplant graft outcomes, direct but narrow); Mortality is supported by Stijn 2015 and Zhang 2024 alone; Safety/Comorbidity is supported only by Zinellu 2015 in chronic kidney disease; and the Deficiency/Prevalence class rests on Marcangeli 2025, a small biomarker study in men aged 20–100. Because each of these outcome classes is touched by one — or at most two — sources, the within-corpus replication that would normally anchor an evidence map is absent, and any effect direction for these classes should be treated as hypothesis-generating rather than confirmatory.\n\nA third limitation concerns population specificity and external-validity boundaries. Pediatric, pregnant, and frail-older-adult populations are represented only by mechanistic or animal work — Verner 2007 in preterm infants, and P Physical Exercise 2025 in older women with sarcopenic obesity (NCT05415176). The Asian cohort literature (Hamada 2011, Domoto 2024, Mizera 2026) and the animal/in-vitro load (Elazab 2025, Adamski 2025, Li 2026, Huo 2026, Bian 2026, Zhao 2025, Berardi 2025, El 2025) further restrict generalisation to non-Asian, non-rodent, free-living adults without organ failure or inborn metabolic disease.\n\nA fourth limitation is the narrow endpoint scope of the human evidence. Patient-important endpoints such as incident cardiovascular events, hospitalisation for heart failure, fragility fracture, or dementia incidence are not reported in any of the in-corpus RCTs, and the energy-drink literature (Basrai 2019, Acute Effects of Energy 2025) addresses acute pressor responses (P < 0.00001) rather than chronic vascular outcomes. To our reading, the balance of the human evidence suggests that taurine may have a role as an adjunct for specific cardiometabolic and exercise endpoints in selected populations, but does not constitute a standalone anti-aging therapy in humans, and the boundary conditions for that adjunct role remain to be established.\n\nFor lifestyle, dietary, or exercise contexts, the data are best interpreted as hypothesis-generating rather than prescriptive: taurine's general-health support within normal dietary intake is a separate question from claims of a proven standalone anti-aging effect, and the chronic-dosing blood-pressure and lipid findings (Waldron 2018; Sun 2016; Sun 2024) should be regarded as adjunct signals rather than endorsement of population-wide supplementation. The most informative single next step is a prespecified, chronic-dosing RCT in middle-aged and older adults that pre-registers both a biological-aging primary endpoint (e. For example, the metrics in Effects of Daily Taurine 2025, 4 g/day for 6 months in adults aged 55–75) and cardiometabolic secondaries, so that the current cardiometabolic signal can be disambiguated from the energy-drink acute-effect findings of Acute Effects of Energy 2025. Until such a trial reports, the integrating thesis stands: taurine may exert measurable cardiometabolic effects in selected contexts, and the broader anti-aging case remains to be confirmed in adequately powered, chronic-duration human trials with hard endpoints, and the boundary conditions — including dose, duration, baseline deficiency, and population — remain to be established.\n\n## What This Synthesis Adds\n\nThis synthesis maps 67 included sources on Taurine across 10 outcome classes and a high-density pairwise disagreement map. It separates endpoint-specific evidence from broad geroprotection claims so that favorable biomarker signals are not treated as proof of durable healthspan benefit.\n\nAcross 67 curated reference papers, the evidence base for taurine shows a context-dependent profile. Positive signals appear in: contextual adjacent evidence, cardiometabolic. Negative signals appear in: cardiometabolic. Null findings dominate: contextual adjacent evidence, cardiometabolic. The synthesis surfaces cross-study disagreements across outcome classes — see Cross-Domain Synthesis. The taurine anti-aging case as currently constituted is incomplete: mechanistic plausibility coexists with mixed or sparse human-RCT evidence, and the boundary conditions remain to be established.\n\nThe strongest unresolved contrast is the disagreement between Acute Effects of Energy 2025 and Sun 2016 on cardiometabolic (severity 5/5), which defines the boundary condition future studies must test rather than smooth over.\n\nPrior reviews in the corpus (Sun 2024, Tzang 2024, Wang 2026, Waldron 2018, Almohaimeed 2024) emphasize convergent signals on Taurine. This synthesis adds a design-level evidence-weighting layer and an explicit cross-study disagreement map, keeping boundary conditions visible instead of averaging them away in narrative summary.\n\n### Boundary-Condition Matrix\n\n| Evidence domain | Direct sources | Indirect / mechanism sources | Direction profile | Interpretation boundary |\n|---|---:|---:|---|---|\n| muscle function | 0 | 4 | null, unclear | direct interventional hard-endpoint gap |\n| mechanism | 0 | 2 | null | direct interventional hard-endpoint gap |\n| longevity | 1 | 1 | unclear | replication gap |\n| cardiometabolic | 2 | 11 | mixed, negative, null, positive | conflict-resolution gap |\n| deficiency prevalence | 0 | 1 | null | direct interventional hard-endpoint gap |\n| immune and inflammation | 1 | 7 | null, positive | replication gap |\n| safety and comorbidity | 0 | 1 | null | direct interventional hard-endpoint gap |\n| contextual adjacent evidence | 3 | 32 | null, positive | conflict-resolution gap |\n| mortality and survival | 1 | 0 | mixed | replication gap |\n\n### Evidence-Gap Priority\n\n| Priority | Gap | Rationale |\n|---|---|---|\n| P1 | muscle function: direct interventional hard-endpoint gap | 0 direct and 4 indirect sources; direction profile: null, unclear |\n| P2 | mechanism: direct interventional hard-endpoint gap | 0 direct and 2 indirect sources; direction profile: null |\n| P3 | longevity: replication gap | 1 direct and 1 indirect sources; direction profile: unclear |\n| P4 | cardiometabolic: conflict-resolution gap | 2 direct and 11 indirect sources; direction profile: mixed, negative, null, positive |\n| P5 | deficiency prevalence: direct interventional hard-endpoint gap | 0 direct and 1 indirect source; direction profile: null |\n\n### Next-Study Design Recommendation\n\nThe next high-yield study for Taurine should target the **muscle function** evidence gap, pre-register the primary endpoint, separate clinical from mechanistic endpoints, preserve safety and adherence capture, and include an analysis plan that can falsify the current boundary-condition claim rather than only confirming a favorable direction. Minimum useful design: at least 200 participants per arm, a priority population of adults or older adults with baseline risk in the target outcome domain, and follow-up lasting at least 12 months; shorter or smaller studies should be treated as hypothesis-generating.\n\n## Evidence Snapshot\n\nThe manuscript foregrounds the load-bearing evidence;

a qualifying direct source would be a human interventional or hard-endpoint study of the topic itself. Indirect human, review-level, and mechanistic sources are weighted separately.\n- **Directional signal** is counted within the assigned outcome class only. A `no extracted directional signal` cell means the retained sources in that outcome slice did not yield a coded positive, negative, or mixed direction for that slice; it is not a claim that the source reports no associations anywhere else.\n- **Evidence tier** follows the deterministic tier/directness taxonomy used in the source builder; the prose writer cannot move a source between classes after sources are frozen.\n\n### Load-Bearing Tensions\n\n- Severity 5 disagreement: Acute Effects of Energy 2025 vs Sun 2016; Acute Effects of Energy 2025 reports negative effect on cardiometabolic; Sun 2016 reports positive on the same outcome — direct conflict\n- Severity 5 disagreement: Acute Effects of Energy 2025 vs Waldron 2018; Acute Effects of Energy 2025 reports negative effect on cardiometabolic; Waldron 2018 reports positive on the same outcome — direct conflict\n- Severity 5 disagreement: Tzang 2024b vs Sun 2016; Tzang 2024b reports negative effect on cardiometabolic; Sun 2016 reports positive on the same outcome — direct conflict\n- Severity 5 disagreement: Tzang 2024b vs Waldron 2018; Tzang 2024b reports negative effect on cardiometabolic; Waldron 2018 reports positive on the same outcome — direct conflict\n- Severity 5 disagreement: Chu 2026 vs Basrai 2019; Chu 2026 reports positive effect on cardiometabolic; Basrai 2019 reports negative on the same outcome — direct conflict\n- Severity 4 null vs negative: P Physical Exercise 2025 vs Acute Effects of Energy 2025; Acute Effects of Energy 2025 (negative on cardiometabolic) vs P Physical Exercise 2025 (null on cardiometabolic) — partial conflict\n- Severity 4 null vs negative: P Physical Exercise 2025 vs Tzang 2024b; Tzang 2024b (negative on cardiometabolic) vs P Physical Exercise 2025 (null on cardiometabolic) — partial conflict\n- Severity 4 null vs negative: Acute Effects of Energy 2025 vs Bian 2026; Acute Effects of Energy 2025 (negative on cardiometabolic) vs Bian 2026 (null on cardiometabolic) — partial conflict\n\n## Conclusion\n\nFor Taurine supplementation, the final interpretation is deliberately tiered: the retained clinical and mechanistic evidence profile defines a bounded geroscience rationale, but the corpus does not support treating mechanistic target engagement, intermediate biomarkers, and patient-relevant outcomes as interchangeable evidence. The closing claim should therefore be read as a map of what the retained studies can support, not as a clinical recommendation or a general anti-aging endorsement. Positive signals identify hypotheses and candidate contexts; null, mixed, or adverse signals identify the boundaries that future work must test directly. The evidence hierarchy remains load-bearing here: direct interventional hard-endpoint records carry more interpretive weight than adjacent clinical evidence, and both carry more translational weight than mechanistic or model systems. A stronger future conclusion would require larger direct human samples, prespecified endpoints, longer follow-up, comparable intervention characterization, transparent safety capture, and a consistent direction of effect across clinically proximate outcomes. Until that evidence exists, the paper's conclusion is that the topic is worth structured follow-up only within the boundaries defined by the included source set. That boundary is not a weakness in the paper; it is the main claim that keeps the synthesis reusable. Readers should carry forward the evidence classes separately: favorable mechanistic or surrogate findings can motivate experiments, indirect human findings can prioritize populations and endpoints, and direct clinical findings define the current ceiling for applied interpretation.\n\nPending further trials, the intervention should not be used off-label for geroprotection or anti-aging purposes outside clinical-trial settings given current evidence. Any downstream use should preserve that tiered reading rather than compressing the corpus into a simple yes/no verdict for clinical practice or public messaging.\n\nAdditional corpus sources included animal/preclinical evidence; additional corpus sources informed the synthesis without anchoring a foregrounded quantitative claim and are catalogued for completeness: Silva 2014, Rosa 2014, Tang 2021, Gultekin 2012, Carvalho 2021, Yu 2024, Duan 2023, Shao 2025, Gao 2019, Bae 2019, Abud 2022, Galan 2018, Hove 2019, Carvalho 2021b, Funke 2012, Gavriel 2025, Guan 2025, Overload 2024, Kim 2026, Samadi 2021.\n\nCurrent evidence does not support clinical or policy use for geroprotection; the synthesis is evidentiary, not medical guidance.\n\n## References\n\n- **Yanni 2025.** _Amino acid composition of plant protein-enriched wheat biscuits differentially affects postprandial amino acid responses of overweight/obese compared to normalweight subjects._ European Journal of Nutrition, 2025.

The evidence profile contains 8 direct clinical sources, 57 adjacent clinical sources, and 2 mechanistic or model-system sources, with a high-density pairwise disagreement map across the evidence base.

Subgroup analyses were performed based on daily taurine intake dosage (<3 g or 3 g), overweight (BMI 25-29.9 kg/m 2 ), and obesity (BMI ≥30 kg/m 2 ). RESULTS: The final number of studies that met the inclusion criteria was 9 RCTs.

Patients received oral taurine or placebo (2 g/day) from transplant day to day 30. The primary outcomes were changes in liver enzymes and bilirubin. Secondary outcomes included mortality, intensive transplantation unit (ITU)/hospital stay, and ventilation duration. RESULTS: Of 225 patients, 56 were excluded (29 refusals, 27 early deaths).

METHODS: Building on these findings, we identified candidate nutrients found in foods that could enhance brain GSH production as a possible approach to sustain motivated behaviors. In primary astrocytes in vitro, we discovered that taurine was able to efficiently increase GSH production and protect mitochondria from oxidative stress damage, but only when levels of vitamin B9 were adequate.

In this study, our results demonstrate that topical taurine supplementation promotes the expression of tight junction (TJ)-related proteins and enhances collagen production, effectively restoring skin homeostasis in sleep-deprived female mice. Mechanistically, taurine upregulates the expression of TMEM38B , a gene encoding the TRIC-B trimeric cation channel, resulting in increased intracellular calcium ion levels. This, in turn, promotes the upregulation of TJ-related proteins, such as ZO-1, occludin, and claudin-11 in epidermal cells, while also enhancing the expression of type III collagen in fibroblasts, thus restoring skin homeostasis.

The evidence profile contains 8 direct clinical sources, 57 adjacent clinical sources, and 2 mechanistic or model-system sources, with a high-density pairwise disagreement map across the evidence base. Positive study-level signals are summarized in the contextual adjacent evidence, cardiometabolic, immune and inflammation outcome classes, null signals in the contextual adjacent evidence, cardiometabolic, immune and inflammation outcome classes, and negative signals in the cardiometabolic outcome class. The paper therefore interprets the corpus as a tiered evidence profile rather than as a single pooled effect. The conclusion is that Taurine supplementation 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.","The conclusion is that Taurine supplementation 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.","13 included sources were assigned to this outcome class. Directional coding: mixed=1, negative=3, null=6, positive=3. Directness coding: direct=2, indirect=1, review=10.","Evidence for this outcome class is represented in the structured results table, but the retained narrative paragraphs were more strongly assigned to adjacent outcome classes. The synthesis therefore treats this class as context for cross-domain interpretation rather than as a standalone prose claim.","A second limitation is single-source dependence for several outcome classes that nevertheless appear in the synthesis. The Longevity class is supported only by Mottaghi 2026 (liver-transplant graft outcomes, direct but narrow); Mortality is supported by Stijn 2015 and Zhang 2024 alone; Safety/Comorbidity is supported only by Zinellu 2015 in chronic kidney disease; and the Deficiency/Prevalence class rests on Marcangeli 2025, a small biomarker study in men aged 20–100. Because each of these outcome classes is touched by one — or at most two — sources, the within-corpus replication that would normally anchor an evidence map is absent, and any effect direction for these classes should be treated as hypothesis-generating rather than confirmatory.","A fourth limitation is the narrow endpoint scope of the human evidence. Patient-important endpoints such as incident cardiovascular events, hospitalisation for heart failure, fragility fracture, or dementia incidence are not reported in any of the in-corpus RCTs, and the energy-drink literature (Basrai 2019, Acute Effects of Energy 2025) addresses acute pressor responses (P < 0.00001) rather than chronic vascular outcomes. To our reading, the balance of the human evidence suggests that taurine may have a role as an adjunct for specific cardiometabolic and exercise endpoints in selected populations, but does not constitute a standalone anti-aging therapy in humans, and the boundary conditions for that adjunct role remain to be established.","Across 67 curated reference papers, the evidence base for taurine shows a context-dependent profile. Positive signals appear in: contextual adjacent evidence, cardiometabolic. Negative signals appear in: cardiometabolic. Null findings dominate: contextual adjacent evidence, cardiometabolic. The synthesis surfaces cross-study disagreements across outcome classes — see Cross-Domain Synthesis. The taurine anti-aging case as currently constituted is incomplete: mechanistic plausibility coexists with mixed or sparse human-RCT evidence, and the boundary conditions remain to be established."]}},{"name":"evidence_table.csv","media_type":"text/csv","content":"study,population,intervention_or_exposure,comparator,endpoint,effect,risk_of_bias,directness\r\nAmino acid composition
