Berberine Phytomax delivers clinically studied Berbevis®, a unique phytosomal berberine formulation that combines berberine extract with sunflower lecithin, pea protein, and grape seed extract. The phytosome delivery system enhances bioavailability by embedding berberine in a phospholipid matrix, making it easier for the body to absorb and retain berberine in the bloodstream.
