White kidney bean extract (Phaseolus vulgaris) is a carbohydrate-blocking supplement that is getting positive reviews online for weight loss.
Research shows that this supplement can promote a modest effect for reducing body fat composition, improving waist circumference and controlling blood sugar levels.
User reviews of White Kidney Bean supplements on Amazon are largely positive, with many products receiving a 4 or 5 star rating.
Users say that they take this product to support their weight loss efforts and that it helps to make them feel full, reduce cravings and avoid the “groggy” feeling after eating a high-starch meal.
White kidney beans are a member of the legume family (leguminosae) and are commonly referred to as cannellini beans. They contain a phytonutrient called phaseolamin which is known to inhibit the actions of alpha-amylase, a digestive enzyme that targets starches in the mouth and again in the small intestines.
When the digestion of the carbohydrates is blocked or impeded, these carbohydrates go through the digestive system and exit without being fully assimilated into the bloodstream. The end effect is that the calories (energy) that they contained does not contribute toward the individual’s caloric intake.
Since calorie input is reduced, weight loss goals are easier to achieve. White kidney bean capsules may also reduce the risk of health complications that can arise from chronically ingesting excessive amounts of carbohydrates.

White Kidney Bean Extract for Heart Health
In the Western diet, the majority of the calories consumed by humans are in the form of carbohydrates.
Although blocking starch digestion and absorption is not recommended as a primary method for controlling weight, it is showing to be effective as an adjunct therapy. However, it should be used alongside proper food intake and daily exercise.
In some White Kidney Bean reviews, this supplement is recommended for use when you are on a vacation or planning to dine out in a situation where you are likely to consume more carbohydrates than normal.
This may not only prevent weight gain, it may also confer positive benefits for heart health related to lower carbohydrate absorption in the body.
Once broken down via alpha-amylase into monosaccharides, carbohydrates are either used right away for energy, converted to glycogen and stored in the liver, or converted to triglyceride fats and stored in special fat storage centers called adipocytes.
Storing away and carrying too much fat will eventually lead to overweightness or obesity. It is known further that obesity puts individuals at significantly higher risk levels for developing heart disease, coronary artery disease, stroke, diabetes mellitus, cancer and numerous other health conditions and diseases.
In various white kidney bean extract trials, phaseolamin has been shown to possibly:
- Decrease triglyceride levels, thereby improving blood-lipid profiles;
- Lower the risk factors for high cholesterol, high lipid counts and low density lipid cholesterol levels;
- Help to elevate high density lipid cholesterol levels;
- Decrease the odds for developing coronary artery disease and/or heart disease.

However, it should not be used by diabetics without the prior approval of your doctor as this supplement could interact with some pharmaceutical drugs used to treat diabetes symptoms. The combination could result in excessively low blood sugar levels in some individuals.
Researchs shows Phaseolus vulgaris can improve reactive hypoglycemia (prediabetes) and diabetes mellitus type II symptoms. It acts to naturally enhance the utilization of glucose in the bloodstream, and to prevent steep spikes of blood sugar following a high-carbohydrate meals. This could also reduce the among of insulin secreted by the pancreas and possibly reduce insulin resistance.
Because of its capacity to lower blood glucose, levels phaseolamin supplementation is not recommended for those diagnosed with prediabetes or diabetes if prescription medications are being administered.
