> Neither is berberine any version of Ozempic, which is an analogue of glucagon-like-peptide-1 (GLP-1), a natural hormone that regulates blood sugar and helps people feel full. Berberine has nothing to do with GLP-1.

> Perhaps the most interesting laboratory finding, given the rising global tide of type 2 diabetes, is the control that berberine may exert over blood sugar. But there is a problem. Berberine is virtually insoluble in water and has low intestinal absorption which means it has poor bioavailability. […] Because of berberine’s poor bioavailability, supplements on the market are likely to be useless. However, some derivative of berberine, may yet make it to the physician’s prescription pad. But it won’t be for weight loss.
