If you eat a high-carbohydrate diet, then White Kidney Bean Extract may be one of the best supplements. This product should be used in conjunction with a healthy diet and exercise regimen; however, it is very effective for individuals who eat a high-carb diet. It works by blocking the enzyme alpha-amylase, which is responsible for breaking down carbohydrates and turning them into sugar. Blocking this enzyme improves how the body metabolizes carbs, lowers the glycemic index of many foods, and boosts your overall weight loss. This supplement contains 1200mg of White Kidney Bean Extract. Its other ingredients include Gelatin, Microcrystalline Cellulose, and Magnesium Stearate.
