Amylase Inhibitors
Also indexed as: Phaseolamin, Starch Blockers, Wheat Amylase Inhibitor, White Kidney Bean Extract
What do they do?
Amylase inhibitors are also known as starch blockers because they contain substances that prevent dietary starches from being absorbed by the body. Starches are complex carbohydrates that cannot be absorbed unless they are first broken down by the digestive enzyme amylase and other, secondary, enzymes.1 2 They are claimed to be useful for weight loss, but when they were first developed years ago, research did not find them very effective for limiting carbohydrate absorption.3 4 5 6 Later, however, highly concentrated versions of amylase inhibitors did show potential for reducing carbohydrate absorption in humans.7 8 9
Purified starch blocker extracts, when given with a starchy meal, have also been shown to reduce the subsequent rise in blood sugar levels of both healthy people and diabetics.10 11 12 13 This effect could be helpful in the treatment of blood sugar disorders.
Where are they found?
Amylase inhibitors can be extracted from several types of plants, especially those in the legume family. Currently available Amylase inhibitors are extracted from either white kidney bean or wheat.
Amylase inhibitors have been used in connection with the following conditions (refer to the individual health concern for complete information):
Health Concerns
Diabetes
Weight loss and obesity
Who is likely to be deficient?
Amylase inhibitors are not essential nutrients and are not normally produced in the body, so no deficiency is possible.
How much is usually taken?
Depending on the potency of the amylase inhibitors , typical intake is 1,500 to 6,000 mg before meals.
Are there any side effects or interactions?
High amounts of amylase inhibitors may cause diarrhea due to the effects of undigested starch in the colon.14 15 Diabetics taking medications to lower their blood sugar should not take amylase inhibitors without first consulting a doctor.
At the time of writing, there were no well-known drug interactions with amylase inhibitors.
