White Kidney Bean
A natural extract that helps block the digestion and absorption of carbohydrates.
Also known as: Phaseolus vulgaris extract • Carb Blocker
Overview
White Kidney Bean extract is a popular weight loss supplement often marketed as a 'carb blocker.' It contains a substance called phaseolamin, an alpha-amylase inhibitor. This inhibitor works by preventing the enzyme alpha-amylase from breaking down complex carbohydrates into simple sugars. As a result, fewer carbohydrates are absorbed by the body, which can lead to a reduction in calorie intake and support weight management.
