Overview Information

Phaseolus vulgaris is a bean plant. Various types of dry beans are produced from this plant, including kidney beans, black beans, pinto beans, navy beans, and many others. Some types of these dry beans or the remaining husk can be used to make an "extract." This extract is used as medicine.

Phaseolus vulgaris is most commonly taken by mouth for weight loss and obesity. It is also commonly taken for diabetes, but there is limited scientific evidence to support this use.

How does it work?

Phaseolus vulgaris beans and bean pods are a source of dietary fiber. Fiber might help to prevent cholesterol absorption and increase the elimination of fat from the diet.

Products containing Phaseolus vulgaris bean extracts often claim to be "starch blockers." Promoters offer this as a rationale for using their products for weight loss. Some research shows that these products can decrease the absorption of starch. However, other research shows that these products do not decrease starch absorption.


Uses & Effectiveness?

Possibly Effective for

  • Obesity. Many early studies show that Phaseolus vulgaris helps reduce body weight and waist size in overweight people. Most research has examined the variety of Phaseolus vulgaris known as white kidney bean. White kidney bean extract seems to work best when taken in a dose of 1000 mg three times per day by overweight people who eat high amounts of carbohydrates. Taking lower doses of white kidney bean extract doesn’t seem to reduce body weight, but it might help reduce body fat.

Insufficient Evidence for

  • Colon and rectal cancer. Early research has found that eating Phaseolus vulgaris beans, including baked beans, kidney beans, pinto beans, lima beans, and navy beans, is linked with a reduced chance of recurrence in people with advanced colon and rectal cancer.
  • Diabetes. Early research suggests that taking a combination of Phaseolus vulgaris bean pod, white mulberry, and bilberry three times per day for 2 months might lower blood sugar by almost 25% in people with type 2 diabetes. Other early research shows that eating a variety of Phaseolus vulgaris known as green beans three times per day for one week reduces average blood sugar, total cholesterol, and triglycerides in people with uncontrolled diabetes. Also, some early research shows that eating the Phaseolus vulgaris beans known as almonga or curruquilla reduces postmeal blood sugar and insulin levels in people with type 2 diabetes who are taking the drug metformin.
  • High cholesterol. Early research suggests that taking a combination of extracts from carob and the Phaseolus vulgaris variety known as white kidney bean slightly lowers cholesterol levels in obese people and increases the amount of fat that leaves the body in the stool.
  • Lung cancer. Some early research suggests that men and women who consume a higher amount of dietary phytoestrogens, such as isoflavones from Phaseolus vulgaris beans and soy, have a lower risk of developing lung cancer compared to those who consume smaller amounts. Men seem to benefit more than women.
  • Urinary tract infections (UTIs).
  • Kidney stones.
  • Other conditions.
More evidence is needed to rate the effectiveness of bean pod for these uses.

Side Effects

Side Effects & Safety

There is some evidence that Phaseolus vulgaris bean extracts are POSSIBLY SAFE for most adults when taken by mouth, short-term. Most research has evaluated a specific extract from the Phaseolus vulgaris variety known as white kidney bean (Phase 2, Pharmachem Labs). This product appears to be safe in doses of up to 3 grams daily for 2-3 months. Other white kidney bean extracts also seem to be safe when used for up to 3 months. Eating large amounts of fresh Phaseolus vulgaris bean husks is POSSIBLY UNSAFE. Raw husks contain chemicals called lectins. These chemicals can cause stomach upset, nausea, vomiting, and diarrhea. Cooking destroys these chemicals.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There is not enough reliable information about the safety of taking Phaseolus vulgaris bean extracts if you are pregnant or breast feeding. Stay on the safe side and avoid use.

Diabetes: Phaseolus vulgaris beans and bean pod may lower blood sugar. If you have diabetes, monitor your blood sugar closely. The dose of your diabetes medications may need to be adjusted by your healthcare provider.



Moderate Interaction

Be cautious with this combination

  • Medications for diabetes (Antidiabetes drugs) interacts with PHASEOLUS VULGARIS

    Bean pod might decrease blood sugar. Diabetes medications are also used to lower blood sugar. Taking bean pod along with diabetes medications might cause your blood sugar to go too low. Monitor your blood sugar closely. The dose of your diabetes medication might need to be changed.

    Some medications used for diabetes include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, pioglitazone (Actos), rosiglitazone (Avandia), chlorpropamide (Diabinese), glipizide (Glucotrol), tolbutamide (Orinase), and others.



The following doses have been studied in scientific research:



  • For obesity: Most research has evaluated the variety of Phaseolus vulgaris known as white kidney bean. Doses of 1000 mg of white kidney bean extract have been taken two or three times daily for up to 12 weeks. Lower doses of 445-1000 mg of white kidney bean extract have also been used daily for up to 13 weeks to reduce body fat, but these lower doses don’t seem to reduce body weight.
