Berberine is an alkaloid that occurs naturally in a variety of medicinal plants, including the roots of Berberis vulgaris (barberry). It has a long history of therapeutic use, with a large body of research focusing on its success in managing blood glucose, blood lipids, and insulin sensitivity (Tabeshpour et al., 2017). Multiple clinical studies support the benefits of berberine when taken at a dose of 500 mg twice per day (Firouzi et al., 2018).

Berberine’s activity begins during digestion when it inhibits some of the enzymes responsible for breaking down carbohydrates and starchy foods in the digestive tract. This helps lower the amount of glucose that is absorbed into the bloodstream (Firouzi et al., 2018). When glucose is absorbed, berberine helps the body use it more efficiently by activating an enzyme called AMP-activated protein kinase (AMPK). This encourages glucose uptake into cells and stimulates its conversion into energy (Firouzi et al., 2018).
