Fabenol® (White Kidney Bean Extract — Indena)

Fabenol® is a standardized white kidney bean (Phaseolus vulgaris) extract from Indena that inhibits alpha-amylase, the enzyme that digests starch. By temporarily slowing starch breakdown, it reduces the sugar and calories absorbed from starchy meals, supporting weight and carbohydrate management.

Fabenol is researched primarily for Weight Management. In a randomized controlled trial, white kidney bean extract supported reductions in body weight and body fat as part of a calorie-controlled approach.
