Background

The common bean (Phaseolus vulgaris) is grown in semitropical areas of the world. Beans vary in color and shape and are a cheap and nutritious food. They are typically high in protein, fiber, and nutrients, and are usually low in fat.
Early research suggests that beans may reduce cholesterol levels and body weight. They may also benefit people with diabetes. Canned refried black beans may be a good source of iron for those with iron deficiency.
Some studies report that beans act as "carb blockers" by helping to block the process of carbohydrate digestion. A product called Phase 2? Carb Controller (Pharmachem Laboratories, Kearny, NJ) has been found to promote weight loss and reduce blood glucose after meals.

Various studies have found that beans may act as "carb blockers" and slow the digestion and absorption of carbohydrates. A bean extract product called Phase 2? Carb Controller (Pharmachem Laboratories, Kearny, NJ) has been found to lower blood glucose and insulin after eating in both healthy and diabetic people. However, the results are not consistent, and more research is needed.

Tradition / Theory

The below uses are based on tradition, scientific theories, or limited research. They often have not been thoroughly tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. There may be other proposed uses that are not listed below.

Dosing

Adults (18 years and older)
To treat high cholesterol in overweight or obese people, two 150-milligram capsules of northern white kidney bean with locust bean gum extract have been taken by mouth three times daily for three months. A dose of 1,500 milligrams of bean pod extract (Phase 2?, Pharmachem Labs) has been taken by mouth twice daily with meals. A meal of consisting of 130 grams of dried, cooked pinto beans has been taken by mouth daily for 12 weeks. A dose of 1/2 cup of vegetarian baked beans has been taken by mouth for eight weeks.
To promote weight loss, 1,000-1,500 milligrams of a specific bean pod extract (Phase 2?, Pharmachem Labs) has been taken by mouth twice daily, with lunch and dinner.
Note: Secondary sources say that the ingredients in commercially available bean extracts such as Phase 2? may vary among products.
Note: According to Pharmachem Laboratories Inc., doses of Phase 2? should not exceed 6-10 grams daily.

Safety

The U.S. Food and Drug Administration does not strictly regulate herbs and supplements. There is no guarantee of strength, purity or safety of products, and effects may vary. You should always read product labels.

Interactions

Interactions with Drugs
Beans may lower blood sugar levels. Caution is advised when using medications that may also lower blood sugar. People taking insulin or drugs for diabetes by mouth should be monitored closely by a qualified healthcare professional, including a pharmacist. Medication adjustments may be necessary.
Beans may cause low blood pressure. Caution is advised in people taking drugs that lower blood pressure.
Beans may also interact with anticancer agents, antifungals, antiobesity agents, antiretrovirals, cholesterol-lowering agents, and laxatives.
