Beanblock® is a standardized white kidney bean (Phaseolus vulgaris) extract from Indena that contains natural alpha-amylase inhibitors, compounds that temporarily slow the digestion of dietary starch.

Beanblock is researched primarily for Weight Management and Metabolic Health. In a clinical study of mildly overweight adults, the standardized bean extract supported weight management as part of a calorie-controlled program, by limiting starch digestion.
