Benefits
Weight and fat loss
In a 12-week randomized controlled trial, a proprietary white kidney bean alpha-amylase inhibitor promoted weight and fat loss versus placebo.
Carbohydrate blocking
By inhibiting starch-digesting enzymes, the extract reduces the sugar and calories absorbed from starchy foods.
Post-meal glucose support
Slower starch digestion blunts the rise in blood sugar after a starchy meal.
Mechanism of action
Alpha-amylase inhibition
Phaseolamin binds and temporarily inactivates alpha-amylase, slowing the breakdown of starch into absorbable sugars.
Reduced caloric absorption
With less starch digested in the small intestine, some passes onward undigested, lowering the meal's effective calorie load.
Clinical trials
12-week, double-blind, placebo-controlled randomized trial of a proprietary white kidney bean alpha-amylase inhibitor on weight and fat loss. (Jäger et al. 2024, Scientific Reports)
Adults.
The white kidney bean inhibitor promoted weight and fat loss versus placebo with acceptable safety.
