Across 373 first-hand reports, people mentioned a side effect 28 times (about 8 per 100 reports). The most common: stomach issues, constipation, anxiety. User reports show what people notice — they can't tell you whether Berberine is safe for you.
“I find it makes a huge difference in keeping my BG stable. I've tested a dozen products/ingredients and berberine/lipo berberine/DHB all work fantastically.”
“I actually tried Berberine which is an OTC supplement with similar effects and I almost passed out, my insulin dropped so much I couldn’t think or focus clearly at all.”
“I've had great results from using berberine, it's a powerful supplement that works in more than one pathway.”
“I started berberine for high blood sugar but quickly noticed mood and energy enhancing effects from it. I've been taking 500 mg daily...I experienced the worst gastrointestinal issues ever, pure yellow diarrhea and smelly piss.”
“I feel really really happy, I keep dancing lol. Probably placebo, but I didn't expect feel good mood benefits!”
“If I take it before a high carb meal, I don’t feel sleepy afterwards (which I assume means my blood sugar isn’t spiking as much).”
Conclusion: Treatment with berberine may be safe since it does not increase the incidence of total adverse events and the risk of hypoglycemia. Systematic Review Registration: https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=292975, identifier CRD42021292975.
Conclusion: Berberine is a safe medicinal plant ingredient that improves various clinical outcomes; however, there is a need for improvement of methodological quality in published meta-analyses. Additionally, the clinical effects of berberine need to be confirmed in high-quality RCTs.
Conclusion: There is strong evidence supporting the clinical efficacy and safety of berberine in the treatment of DM, especially as an adjunctive therapy. In the future, this may be used to guide targeted clinical use of berberine and the development of medications seeking to treat patients with T2DM and dyslipidemia.
