Watch out for

  • Berberine, gymnema, chromium, alpha-lipoic acid, bitter melon, fenugreek, and cinnamon extract each have documented glucose-lowering activity. Added on top of a diabetes medication the effects can stack, and blood sugar can drop lower than the medication alone would take it — the risk is highest alongside insulin or a sulfonylurea (such as glipizide, glyburide, or glimepiride). Low blood sugar can show up as shakiness, sweating, confusion, or a racing heartbeat. Tell the prescriber or pharmacist who manages the diabetes medication before adding any of these so glucose monitoring can be planned, and do not change the medication on your own.
