Berb-Evail® contains 400 mg of the plant alkaloid berberine (from Berberis aristata) per softgel for the primary purpose of supporting healthy blood sugar metabolism and normal insulin sensitivity. Berberine has also been shown to exhibit potential antimicrobial properties.* Berb-Evail® is manufactured using Designs for Health's Evail™ technology, and it is an all-natural formulation that improves the absorption and delivery of berberine. This process uses a proprietary blend of medium-chain triglyceride (MCT) oil, non-soy derived lecithin, and tocotrienols, without the use of potentially harmful surfactants.
