Benefits
Carbohydrate and weight management
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.
Gentler post-meal glucose
By slowing starch breakdown, the extract can blunt the spike in blood sugar that follows a starchy meal.
Appetite and intake support
Slower carbohydrate absorption is associated with steadier energy and may support a feeling of fullness after meals.
Mechanism of action
Alpha-amylase inhibition
Phaseolamin binds to the digestive enzyme alpha-amylase, temporarily reducing its ability to break dietary starch into absorbable sugars.
Reduced starch absorption
With less starch digested in the upper gut, a portion passes further along, lowering the immediate caloric and glycemic load of the meal.
Clinical trials
Clinical study of Beanblock (standardized Phaseolus vulgaris extract) in mildly overweight subjects on a calorie-controlled diet. (Luzzi et al. 2014, European Review for Medical and Pharmacological Sciences)
Mildly overweight adults.
The bean extract supported weight and waist management compared with diet alone, consistent with its starch-blocking mechanism.
