WHITE KIDNEY BEAN EXTRACT 20:1 (PHASEOLUS VULGARIS)(BEAN)

White Kidney Bean Extract, derived from Phaseolus vulgaris, is a highly sought-after ingredient in the supplement industry, known for its distinct physiological properties. This 20:1 concentrated extract signifies that 20 parts of raw white kidney beans are used to produce one part of the potent extract, ensuring a high concentration of its beneficial compounds. Sourced from the common bean, a legume cultivated globally for centuries, Phaseolus vulgaris has a long history of use in various culinary traditions. Its concentrated extract isolates the key bioactive constituents, making it a powerful tool for specific health applications. The beans themselves are rich in fiber, protein, and various micronutrients, but the extract is specifically processed to amplify its targeted effects. This ingredient is typically presented as a fine, free-flowing powder, making it versatile for incorporation into a wide range of supplement formulations, from capsules to functional foods. Its natural origin and well-defined mechanism of action contribute to its appeal as a functional ingredient.

The primary mechanism of action for White Kidney Bean Extract revolves around its potent alpha-amylase inhibiting activity, largely attributed to a glycoprotein complex known as phaseolamin. Alpha-amylase is a digestive enzyme responsible for breaking down complex carbohydrates (starches) into simpler sugars, which are then absorbed into the bloodstream. By inhibiting this enzyme, phaseolamin effectively reduces the digestion and subsequent absorption of dietary starches, thereby mitigating their caloric impact and influence on post-prandial glucose levels. This mechanism supports healthy carbohydrate metabolism and can be particularly beneficial for individuals aiming to manage their weight or maintain stable blood glucose. Research indicates that this reduction in carbohydrate breakdown can lead to a lower glycemic response after meals. Studies, such as one published in the Journal of Nutritional Biochemistry, have elucidated the dose-dependent inhibitory effects of Phaseolus vulgaris extract on alpha-amylase activity in vitro and in vivo, substantiating its role in modulating carbohydrate digestion.

White Kidney Bean Extract 20:1 is a versatile ingredient widely employed in dietary supplements targeting weight management and blood sugar support. It is commonly formulated into capsules, tablets, and powdered drink mixes, often alongside complementary ingredients like chromium picolinate for glucose metabolism or green tea extract for thermogenic effects. Quality considerations are paramount for WKB extract, including standardization for active phaseolamin content to ensure consistent efficacy, as well as rigorous testing for purity and absence of contaminants. Numerous clinical studies support its utility. For instance, a meta-analysis published in Nutrients reviewed multiple randomized controlled trials, concluding that Phaseolus vulgaris extract significantly contributes to weight loss and reduction in body fat mass in overweight and obese individuals, particularly when consumed with carbohydrate-rich meals. Another study in The FASEB Journal demonstrated its ability to reduce the glycemic index of a high-carbohydrate meal. These scientific findings underscore its evidence-based role in supporting metabolic health and healthy body composition.
