The is no proof (there is never proof in science) but there is reason to be suspicious.

Glyphosate exposure, either through active ingredient alone or commercial herbicide formulations, has the potential to induce dysbiosis by creating an imbalance between commensal members of the gastrointestinal microbiome and opportunistic pathogens. Glyphosate may be a critical environmental trigger in the etiology of several disease states associated with dysbiosis, including celiac disease, inflammatory bowel disease and irritable bowel syndrome. Glyphosate exposure may also have consequences for mental health, including anxiety and depression, through alterations in the gut microbiome. However, the research surrounding glyphosate’s effects on the gut microbiome also suffers from numerous methodological weaknesses including artificially high-doses, insufficient duration, proprietary ingredients and an over reliance on animal models. Future long-term studies examining physiologically relevant doses in both healthy and genetically susceptible populations are warranted to determine the real risk posed to human health.
