Product Overview
White Kidney Bean Extract is derived from the mature seeds of Phaseolus vulgaris, a widely cultivated legume traditionally valued for its rich nutritional and therapeutic profile. Modern phytochemistry has isolated a unique glycoprotein complex within white kidney beans known as Phaseolamin, which functions as a natural alpha-amylase inhibitor.
Promaxbio offers premium-grade White Kidney Bean Extract standardized via High-Performance Liquid Chromatography (HPLC) and enzymatic assay testing to guarantee consistent carbohydrate-blocking potency. Sourced from selectively harvested seeds, our extract provides B2B dietary supplement manufacturers, formulators, and weight management brands with a reliable, high-purity raw material tailored for modern metabolic health and low-carb wellness formulations.

Functional Applications
- Carbohydrate & Starch Blocking: Inhibits the activity of salivary and pancreatic alpha-amylase enzymes, temporarily slowing down the breakdown of complex dietary starches into absorbable glucose.
- Healthy Glycemic Response: Helps blunt postprandial blood sugar spikes following carbohydrate-heavy meals, supporting balanced overall glycemic control.
- Weight Management Support: Reduces net caloric absorption from starchy foods, making it a cornerstone ingredient in natural weight loss and body composition formulations.
- Metabolic Wellness: Assists in managing carbohydrate intake without reliance on stimulants, fitting seamlessly into keto-friendly or low-glycemic lifestyles.
Formulation Combinations
- Carb-Blocker & Metabolic Stacks: Synergizes effectively with Gymnema Sylvestre Extract, Chromium Picolinate, and Berberine HCl for comprehensive blood sugar support.
- Weight Management Blends: Pairs seamlessly with Green Tea Extract (EGCG), Garcinia Cambogia, and L-Carnitine for advanced thermogenic and caloric-control capsules.
- GLP-1 Natural Companion Formulas: Formulated alongside metabolic regulators to support modern natural weight management protocols.
Market Opportunities
- Carb-Blocking & Diet Support Sector: Massive global consumer demand for natural ingredients that allow individuals to enjoy carbohydrate-rich meals with reduced caloric impact.
- Metabolic Health & Blood Sugar Category: Growing consumer preference for plant-derived enzymatic inhibitors over synthetic weight-loss drugs.
- Customizable Potency Options: B2B formulators can choose from various standardized enzyme activity units (U/g) to match specific capsule or powder product tiers.

Frequently Asked Questions (FAQ)
Q1: How does White Kidney Bean Extract work in the body?
A: It acts as an alpha-amylase inhibitor, meaning it temporarily neutralizes the enzyme responsible for converting complex dietary starches into simple sugars, allowing a portion of the starch to pass through the digestive tract unabsorbed.
Q2: When is the best time to take supplements containing this extract?
A: It is most effective when consumed immediately before or with the first few bites of a meal containing complex carbohydrates or starchy foods.
