Review decision

To resubmit, address

1. Populate Key Findings with concrete, source-anchored statements for each outcome slice (e.g., for Cardiometabolic: Sheng 2025 reports HR 1.50 for elevated ePWV and CAD incidence; Lu 2026 reports NCAA HR 1.21 for CVD risk; Luo 2025 meta-analysis reports FMD improvement from L-citrulline; for Deficiency Prevalence: Azizzadeh 2026 reports EVA prevalence of 12.2% with specific determinants)
2. Add substantive narrative under each outcome subsection (Contextual Adjacent Evidence, Cardiometabolic, Deficiency Prevalence, Longevity, Mechanism, Safety and Comorbidity) that links at least one specific quantitative or qualitative finding to its source, or explicitly state null/mechanistic-only status
3. In the Conclusion, tie the tiered interpretation to the specific bundle: name which 1 direct source (Sheng 2025) carries the most interpretive weight and explain why the remaining 12 sources do not change that weight
4. Clarify which source is the '1 direct clinical source' — based on bundle content this appears to be Sheng 2025 (prospective cohort with hard CAD endpoint), and state this explicitly so readers can audit the evidence hierarchy
5. Expand the Limitations to specifically note that several admitted sources are protocols (Rodilla 2026, Vicente-Gabriel 2024, Joshi 2025) or cross-sectional observational designs that cannot support causal claims even individually

Major issues

• Key Findings section is effectively empty: it contains only boilerplate outcome-class and source-context notes with no substantive findings, leaving the reader unable to see what the synthesis actually concluded beyond the abstract
• Cardiometabolic outcome slice is asserted twice (once as a populated row in the table, once as a standalone subsection) but the standalone subsection contains no narrative findings beyond a heading
• Deficiency Prevalence subsection is described in the table but the body text reuses the same null boilerplate rather than reporting the specific finding from the cited source (Azizzadeh 2026/LEAD study)

Minor issues

• The Conclusion is long and could be tightened, but this is style not substance
• Several section headings (Conclusion, Limitations) read as house-formulaic rather than synthesizing the specific bundle
• Search summary queries are broad and the screening funnel is reported but the rationale for admitting 1 direct source and excluding others is not fully transparent

Reviewer note

The manuscript has a strong, explicit search summary, a transparent admission funnel, and an appropriately bounded conclusion that correctly identifies the corpus as hypothesis-generating only. The source bundle is verifiable and largely recent (2024–2026), and citations match the cited_as entries. However, the synthesis body is underdeveloped: the Key Findings section is empty boilerplate, and the outcome-class subsections do not narratively report any specific findings even though the bundle contains extractable quantitative results (e.g., Sheng 2025 HR 1.50; Azizzadeh 2026 EVA prevalence 12.2%; Luo 2025 FMD improvement 1.81; Lu 2026 NCAA HR 1.21). This makes the synthesis read more as a metadata report than as an integrated evidence argument. The Conclusion correctly stays within bounds, which is commendable, but it does so by avoiding rather than integrating the evidence. A bounded revision that populates Key Findings and each outcome subsection with source-anchored statements, while retaining the current conservative overclaim posture, would move this toward accept. As submitted, it is competent but incomplete — revise, not reject, because the framework is sound and only the synthesis prose needs to be filled in.
