White Kidney Bean Extract Powder (Phaseolamin, α-Amylase Inhibitor) — Natural Carb Blocker Ingredient
What Is White Kidney Bean Extract?
White kidney bean extract powder is a standardized protein fraction derived from the fruit of Phaseolus vulgaris L. The active component, phaseolamin, is a naturally occurring alpha-amylase inhibitor. It partially blocks the enzyme responsible for breaking starch down into absorbable sugars.
Our extract is standardized to ≥20,000 U/g of α-amylase inhibitory activity and tested under the T/CCCMHPIE 1.26-2018 method. That means potency-verified ingredient, every single batch.
Visually, the powder runs from off-white to light yellow with a fine, uniform particle size that disperses cleanly in dry blends. No off notes. No gritty mouthfeel. Just a clean, plant-sourced functional ingredient ready for encapsulation.
How It Works — and Why Your Customers Want It
When starch enters the digestive tract, α-amylase goes to work converting it to simple sugars. Phaseolamin powder steps in and slows that process down. The result: a portion of dietary starch passes through undigested, reducing the net caloric load from a carbohydrate-containing meal.
This is the mechanism behind white kidney bean extract’s reputation as a go-to carb blocker ingredient and natural starch blocker extract — especially in weight management and metabolic health categories.
What this ingredient is not: a stimulant. Not an appetite suppressant. It works mechanically at the enzymatic level. That is exactly why formulators and consumers who prefer targeted, mechanism-driven ingredients gravitate toward it.
