This rationale is inaccurate as a complete toxicological argument, because the shikimate pathway is present in some commensal bacteria in the mammalian gut. This review appraises the evidence that glyphosate and glyphosate\u2010based herbicides (GBHs) perturb the gut microbiome of mammals. Controlled rodent studies provide the most consistent evidence, with several reporting shifts in community composition, including a depletion of lactobacilli, sometimes accompanied by intestinal inflammation, altered microbial metabolism and increased intestinal permeability. Experimental evidence indicates that luminal aromatic amino acid availability attenuates the antibacterial effect. Formulated products are frequently more disruptive than the active ingredient alone. Some studies suggest that the gut mycobiome is also affected. Neurobehavioural and reproductive outcomes have also been reported, although microbiome\u2010mediated causality is not established in most studies. Glyphosate\u2010induced effects are strongly influenced by dose, by whether the active ingredient or a formulated product is tested, by sex and by a developmental window of exposure. Available human data, confined to in\u00a0vitro systems and small biomonitoring cohorts, are limited. In conclusion, glyphosate and some GBHs can perturb the rodent gut microbiome under defined experimental conditions. These animal findings are relevant to hazard assessment and support inclusion of microbiome endpoints in regulatory toxicology, although the magnitude and health relevance of comparable effects at realistic human exposures remain uncertain.<\/jats:p>","DOI":"10.1002\/jat.70475","type":"journal-article","created":{"date-parts":[[2026,10,7]],"date-time":"2026-10-07T00:19:50Z","timestamp":1791332390000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Effects of Glyphosate and Glyphosate\u2010Based Herbicides on the Mammalian Gut Microbiome: A Critical Review"],"prefix":"10.1002","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1732-4741","authenticated-orcid":false,"given":"Robin","family":"Mesnage","sequence":"first","affiliation":[{"name":"Buchinger Wilhelmi Clinic  \u00dcberlingen Germany"},{"name":"Department of Nutritional Sciences, School of Life Course Sciences, Faculty of Life Sciences and Medicine King's College London  London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,10,6]]},"reference":[{"key":"e_1_2_20_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ntt.2018.04.002"},{"key":"e_1_2_20_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.envint.2024.109243"},{"key":"e_1_2_20_4_1","doi-asserted-by":"publisher","DOI":"10.1186\/s13104\u2010019\u20104534\u20103"},{"key":"e_1_2_20_5_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.chemrestox.3c00091"},{"key":"e_1_2_20_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.scitotenv.2025.180437"},{"key":"e_1_2_20_7_1","doi-asserted-by":"publisher","DOI":"10.1042\/BJ20051397"},{"key":"e_1_2_20_8_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41522\u2010021\u201000198\u20104"},{"key":"e_1_2_20_9_1","doi-asserted-by":"publisher","DOI":"10.3389\/fmicb.2019.00932"},{"key":"e_1_2_20_10_1","doi-asserted-by":"publisher","DOI":"10.3389\/fmicb.2022.873101"},{"key":"e_1_2_20_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.scitotenv.2023.167034"},{"key":"e_1_2_20_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.scitotenv.2022.157973"},{"key":"e_1_2_20_13_1","doi-asserted-by":"publisher","DOI":"10.3389\/ftox.2025.1704231"},{"key":"e_1_2_20_14_1","doi-asserted-by":"publisher","DOI":"10.1093\/jnci\/djac242"},{"key":"e_1_2_20_15_1","doi-asserted-by":"publisher","DOI":"10.1289\/EHP12834"},{"key":"e_1_2_20_16_1","doi-asserted-by":"publisher","DOI":"10.3390\/agrochemicals3010005"},{"key":"e_1_2_20_17_1","doi-asserted-by":"publisher","DOI":"10.1111\/jne.12731"},{"key":"e_1_2_20_18_1","doi-asserted-by":"publisher","DOI":"10.3390\/ijms23105583"},{"key":"e_1_2_20_19_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00218464"},{"key":"e_1_2_20_20_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.jafc.4c04045"},{"key":"e_1_2_20_21_1","doi-asserted-by":"publisher","DOI":"10.1002\/jsde.12293"},{"key":"e_1_2_20_22_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41564\u2010025\u201002035\u20102"},{"key":"e_1_2_20_23_1","doi-asserted-by":"publisher","DOI":"10.1002\/rcm.8668"},{"key":"e_1_2_20_24_1","doi-asserted-by":"publisher","DOI":"10.1126\/science.aau5812"},{"key":"e_1_2_20_25_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ecoenv.2024.117060"},{"key":"e_1_2_20_26_1","doi-asserted-by":"publisher","DOI":"10.1093\/femsec\/fiad065"},{"key":"e_1_2_20_27_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00204\u2010023\u201003622\u20100"},{"key":"e_1_2_20_28_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41598\u2010021\u201082552\u20102"},{"key":"e_1_2_20_29_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.toxlet.2021.12.013"},{"key":"e_1_2_20_30_1","doi-asserted-by":"publisher","DOI":"10.4103\/1673\u20105374.391331"},{"issue":"25","key":"e_1_2_20_31_1","doi-asserted-by":"crossref","first-page":"12164","DOI":"10.1016\/S0021-9258(18)45331-8","article-title":"Degradation of Glyphosate by Pseudomonas sp.
