Landnutra's white kidney bean extract powder is derived from non-GMO Phaseolus vulgaris through a gentle aqueous extraction and purification process. The extract is standardized for α-amylase inhibitory activity measured in IU/g, delivering consistent starch-blocking performance. A dedicated filtration step removes naturally occurring lectins (PHA) while retaining dietary fiber and plant protein, resulting in a fine, soluble powder that blends easily into capsules, tablets, and functional formulations.

FAQ
Q: How does it actually work?
A: It acts as a temporary α-amylase inhibitor, reducing enzymatic starch breakdown and allowing a portion of dietary carbohydrates to pass through the GI tract undigested.
Q: Is White Kidney Bean Extract Powder safe? What about lectins?
A: Yes-Landnutra applies a lectin-removal process that eliminates the GI-irritating compounds found in raw beans, ensuring a non-irritating, well-tolerated extract.
Q: How much should I take?
A: Typical use is 300–500 mg with a starchy meal, adjusted based on the extract's activity strength measured in IU/g.
Q: So… what does it do again?
A: It functions as a carbohydrate management ingredient-slowing starch digestion to support weight management and promote steady postprandial glucose responses.
Q: Any side effects?
A: Rarely, excessive colonic fermentation of undigested starch may cause transient gas. This is formulation-dependent and well-tolerated at recommended dosage levels.
