White kidney bean extract, also known as Phaseolus vulgaris extract or common bean extract, comes from the white kidney bean, a legume native to Central America and South America. White kidney bean extract is sold as a weight-loss supplement that blocks the absorption of starch in food—carbohydrates.
The extract stops the actions of alpha-amylase, which is the enzyme the body uses to break down carbohydrates. Stopping the enzyme prevents the breakdown and absorption of starch in food.
