Safety & Cautions
Side Effects
- Gastrointestinal discomfort (cramping, diarrhea)
- Nausea, especially at higher doses
- Potential interactions with medications metabolized by the liver
- Possible lowering of blood sugar to uncomfortable levels when combined with other glucose-lowering agents
Berberine is generally well-tolerated at standard doses when taken with food, but its potent glucose-lowering effects mean it should be used cautiously alongside diabetes medications or other blood-sugar-lowering supplements. Consulting a healthcare provider before starting berberine is strongly recommended, particularly for those on prescription medications.
