What are the benefits of Berberine?

Berberine may help lower blood sugar and total cholesterol, influence metabolic regulation and sugar cravings, and—when applied directly—may rapidly eliminate canker sores.

• Blood glucose: It activates AMPK, a pathway associated with fasting, and can lower blood glucose strongly; its effects are described as similar to metformin and, in another discussion, comparable to blood-glucose-lowering prescription drugs. 1 2
• Cholesterol: It may lower total cholesterol. The account describes total cholesterol and LDL and HDL appearing to fall in parallel, while one study found a minor increase in HDL. 3
• Metabolic regulation and cravings: By maintaining low-to-moderate blood glucose, berberine may engage fasting-associated pathways; over time, this may help recalibrate the neural circuits that regulate sugar cravings, and some people report fewer cravings. 4 5
• Large meals: Taken with a large, carbohydrate-rich meal, it may blunt the blood-glucose response and make the rise feel less overwhelming; the discussion also cautions that taking it without enough food can cause blood sugar to drop too far. 6
• Canker sores: Direct contact with berberine has been reported to eliminate canker sores very quickly. 7
