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, meaning it partially blocks the enzyme responsible for breaking starch down into absorbable sugars. Our extract is standardized to no less than 20,000 U/g of α-amylase inhibitory activity and tested under the T/CCCMHPIE 1.26-2018 method, so you get a 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 that has earned white kidney bean extract its reputation as a go-to carb blocker ingredient and natural starch blocker extract in the weight management and metabolic health categories.

It is worth emphasizing what this ingredient is not. It is not a stimulant. It is not an appetite suppressant. It works mechanically at the enzymatic level — which is exactly why formulators and consumers who prefer targeted, mechanism-driven ingredients gravitate toward it.

Application Areas

Weight management supplements — standalone carb blocker capsules and tablets positioned around “enjoy carbs smarter.”
Multi-mechanism metabolic formulas — paired with chromium, berberine, green tea, or gymnema in comprehensive glucose-support stacks.
Functional gummies and softgels — consumer-friendly formats that make the carb blocker concept more approachable for retail.
Meal companion powders — stick packs designed to be taken before higher-carb meals, blending white kidney bean extract phaseolamin with digestive-support botanicals.
