Question: What is berberine? Can it really lower blood sugar? Are there any cautions? Which supplements are best?
Answer: Berberine is a compound found in plants such as barberry and goldenseal. There is some clinical evidence that it may lower blood sugar and cholesterol in people with type 2 diabetes. However, berberine may not be safe for certain people and it can interact with a number of medications. In addition, tests by ConsumerLab.com have revealed that some berberine and goldenseal supplements on the market do contain the expected amounts of berberine.
