White Kidney Bean — Reading the “α-Amylase Inhibitor” Spec Correctly
White kidney bean (Phaseolus vulgaris) extract works as a natural α-amylase inhibitor, marketed for carbohydrate-blocking in weight-management formulas. The critical spec is enzyme-inhibiting activity, usually expressed in units (e.g., 1,000–3,000 U/mg) rather than a simple extract ratio — a higher U/mg with a documented assay method (e.g., USP/phaseolamin-type assay) is what justifies premium pricing. Typical use: 500–1,500 mg per day, often split before meals, in weight-management capsules alongside green coffee or glucomannan.
| Parameter | High-Activity (1,600+ U/mg) | Standard Extract | Raw Bean Flour |
|---|---|---|---|
| α-Amylase inhibition | Documented on COA | Varies | Minimal |
| Assay method | USP-type documented | Often absent | N/A |
| Best fit | Clinical-style weight formulas | General use | Food ingredient |
