White Kidney Bean Extract

White Kidney Bean (Phaseolus vulgaris) extract is the classic carbohydrate "starch blocker," working through alpha-amylase inhibition, which we standardise by activity (3000–14000 IU/g) rather than a percentage marker. The off-white, water-soluble powder formulates into weight-management, starch-blocker, blood-sugar and functional-food products as capsules and tablets. Because efficacy is defined by enzyme-inhibition activity, the IU/g assay — not a simple percentage — is the number serious buyers compare. Every lot ships with activity testing and USP-grade contaminant documentation for weight-management brands.
