PRO

  • White kidney beans contain an extract (phaseolous vulgaris) that blocks the action of amylase. Amylase, an enzyme that breaks down dietary carbohydrate into sugar, is released in the mouth (by the salivary glands) and small intestine (by the pancreas).
  • Through its inhibition of amylase activity, white kidney bean extract interferes with breakdown of carbohydrates (e.g., white flour, corn starch, rice) into sugar molecules, and reduces absorption of sugar into the blood.

CON

  • Major side effects of white kidney bean extract include gassiness and bloating.
  • Via the same mechanism by which white kidney bean extract inhibits the action of amylase and interferes with the breakdown of carbohydrates, so it may interfere with digestion and affect absorption of other important nutrients.
  • Through its inhibition of carbohydrate breakdown and metabolism, white kidney bean extract may result in hypoglycemia, especially in diabetics and others who are especially prone to low blood sugars.
  • Available studies showed some potential promise for weight loss, but overall results were minimal and statistically insignificant.

* *ADVISORY* *
Amylase inhibitors must be used with caution in individuals with certain gastrointestinal, kidney, or liver disorders.

DOSAGE: Dosing strategies have included 4-6 g for up to 7 days in diabetic patients, and 3000 units for 30 days for weight loss. Doses ranging between 1500 and 6000 mg have been tried prior to meals.

CONCLUSION: We conclude that while white kidney bean extract shows early interest for weight loss and blood sugar control, additional studies are required to reproduce results. While studies are preliminary, white kidney bean extract may be worth trying for weight loss. If you elect to try it, remember to include it in your list of medications when you visit your doctor and other health care providers.
