What the evidence shows
Monk-fruit (mogroside) extract is US GRAS (2010) and no toxicity signal has surfaced — but after the 2026-08-19 re-read, every one of this claim's five appraisals is a narrative review with zero weight (the one "PRISMA systematic review" pooled nothing and double-listed a trial; two reviews' safety votes were inference from silence over papers containing no toxicology).
The evidence (5)
| Source | Grade | Stance | Quality | Finding |
|---|---|---|---|---|
| Zhang T, Gao Z, Zeng D, Wang Y 2025 · Arch Pharm (Weinheim). 2025 Oct;358(10):e70112 | observational | mixed | low | Narrative review titled 'Mogroside V: A Review of Its Structure, Synthesis, Pharmacokinetics, and Toxicity', but its own account of what it delivers is 'a comprehensive analysis of MOG-V, including its structural characteristics, novel synthetic approaches, and pharmacological investigations' - no toxicity result, dose, species, duration or adverse-event count appears anywhere in the reachable text (PubMed abstract; Wiley full text paywalled). The earlier 'no significant toxicity at dietary levels' was an inference from silence, so no direction is earned. The review also concedes that 'a comprehensive and critical outlook on the synthesis, pharmacological mechanisms, and therapeutic applications of MOG-V remains lacking'. Zero weight as evidence_role: review. |
| Li C et al 2014 · Chin J Nat Med | observational | supports | low | 'The existing research has shown that extracts and individual compounds from S. grosvenorii are basically non-toxic.' [Narrative review, 93 cited sources over 30 years; no search strategy or inclusion criteria stated. No primary data, no human safety trial, and no dose, species, exposure duration or NOAEL anywhere in the abstract. Covers the whole plant and its extracts, not the commercial mogroside sweetener at dietary intake. evidence_role: review - zero weight.] |
| He YL et al 2025 · Phytomedicine | observational | mixed | low | Narrative mechanism review of mogroside V's therapeutic pathways; contains no toxicology, adverse-event or exposure-limit data in the readable text. Its closing appraisal is efficacy-and-translation, not safety: 'MV is a promising multi-target therapeutic candidate. Further studies on bioavailability optimization and clinical translation are warranted.' A review that never examined harm cannot support a safety claim, so the prior supports stance (argument from silence) is withdrawn and the appraisal marked off-scope. |
| Kaim et al. 2025 · Nutrients | observational | supports | low | Systematic review, no pooled safety analysis and no new data: safety rests on adverse-event lines restated from five short trials — 'No severe adverse effects were observed', 'One participant withdrew from the study due to mild gastrointestinal discomfort, but no other adverse effects were observed', 'No serious adverse events were reported, and both groups had high compliance' — the longest of which ran 15 days and three of which were single-session. The review states its own limit: 'Short study durations and the absence of long-term safety data—These represent a critical limitation across the included trials', and concludes 'long-term clinical trials are needed to establish the safety profile of MFE'. Two of the five trials tested multi-herb botanical preparations, not monk fruit alone. Direction still supports tolerability, but zero weight per CONVENTIONS §5 (review reports no new data). |
| Dragomir et al. 2025 · Foods | observational | supports | low | Narrative review, no new data: 'In the U.S., Luo Han Guo, or monk fruit, is generally recognized as safe (GRAS in FDA terms since 2010)' but 'In Europe, it has not yet obtained approval by EFSA, which conducts toxicity studies' — regulatory status, split, not a toxicology finding. |
Disagree, or know a study we missed?
We grade by evidence, not opinions. The way to weigh in is to point us to a study we haven't cited (check the evidence table above first), or to flag a problem with one we have. Every submission is reviewed; if it holds up, the grade updates and shows in Science Changes Its Mind.
Opens a short form. You'll sign in with Google so submissions are tied to a real account — we don't display your identity, and we only accept a link we can verify (PubMed, DOI, ClinicalTrials.gov).
