Berberine might be the best supplement that you can take to reduce your blood glucose. But first you need to consider the disadvantages of any supplement.
Berberine has apparently been an important herbal remedy in Chinese medicine for hundreds, if not thousands, of years. Now, it is becoming increasingly well known in the West.
Growing interest in berberine
The U.S. National Library of Medicine indexes about 4,000 studies in professional journals that include berberine. This is far more than the 800 on bitter melon and the 200 on gymnema sylvestre, which quite a few people have told me they use to manage their blood glucose. It’s clear that interest in berberine is growing fast: more than 1,500 of the 4,000 studies were published in the last five years.
But people use berberine for many conditions. Just 243 of these studies are about berberine and diabetes, and 79 of them are human studies (the others are studies of berberine in animals or in test tubes).
