Berberine is a natural constituent of herbs such as goldenseal, Oregon grape, and barberry. Clinical studies have demonstrated that berberine helps to support already normal glucose and lipid metabolism.* Because berberine is known for its limited bioavailability, this product includes caprate (C10, a medium-chain triglyceride) to promote optimal absorption and maintenance of gastrointestinal comfort during berberine supplementation. Natural color variation may occur in this product.
