Stomach effects
NCCIH lists mild-to-moderate nausea, diarrhea, bloating and constipation as the common side effects of berberine supplements (NCCIH). Chromium can occasionally cause stomach pain or bloating. These usually settle when you take the capsule with food. See how to take MetaGlucent.
Low blood sugar with medication
If you take insulin, metformin, sulfonylureas or other glucose-lowering drugs, adding glucose-supporting ingredients could lower your blood sugar further. Know the signs of hypoglycemia: shakiness, sweating, fast heartbeat, hunger, confusion (MedlinePlus). Talk to your doctor before starting. See MetaGlucent with medications.

See the Discount ›Drug interactions
Berberine may interact with some medicines (NCCIH). Show your bottle to your pharmacist if you take any prescriptions.
Who should avoid it
- Pregnant or breastfeeding women: NCCIH says berberine should not be used then.
- Children and teens under 18.
- Anyone with a serious medical condition without a doctor’s okay.
Cinnamon and coumarin
Cassia cinnamon in large amounts contains coumarin, which can affect the liver in sensitive people (NCCIH). A daily capsule taken as directed is not the same as high-dose cinnamon supplements.
