What are carb blocker or starch blocker pills?

At this point I think we all know that carbs are found in virtually everything that we eat. Most of us love carbs, but know that when it comes to body fat and trying to lose weight, starchy carbs can be problematic. However, the body uses carbohydrates to make glucose, one of the fuels that keeps us moving throughout the day. So what are carb/starch blockers?

Carb/starch blockers are a form of dietary supplement that contain white kidney bean extracts. These extracts help block the amount of carbohydrates that your body absorbs. By reducing the amount of carbs absorbed they reduce your body’s whole day caloric intake. Many people feel that these supplements are great for people who can no resist the urge of consuming carbs/starches. Some advocates even suggest that these pills are good for diabetics, since they lower the glycemic index of the food consumed by the user.

How do carb blockers or starch blockers work?

Carb blockers work when users take them just prior to eating meals, which may be high in carbs. These supplements work by inhibiting alpha amylase, a digestive enzyme found in the body that is responsible for the digestion of starches. As you consume food, it travels along your gastrointestinal tract, and the supplements work by limiting the amount of carbs/starch that is used, leaving a portion undigested, and eventually eliminated as waste. As these calories are not absorbed, weight loss is promoted through the reduction of calories your body consumes and converts to glucose.

Are there any side effects from taking carb blockers?

As with any medication or supplement, there are side effects to regularly using carb blocker pills. Starch blocker pills are not fat blockers. That’s something that should be understood completely. They do not prevent the absorption of calories from protein or fat, only starchy carbohydrates. Also, Phase 2 Starch blockers, or carb blocker pills, can prevent the absorption of essential nutrients. Therefore, users should be careful that they do not become nutrient deficient due to prolonged usage.

Carbohydrate blockers can have additional side effects as well, such as: flatulence, heartburn, diarrhea, nausea, vomiting, and bloating. Certain side effects many disappear with continued use, and users should discuss side effects with the doctor.


There is much debate in the medical world on whether carb blockers are successful when it comes to losing weight and blocking the absorption of starchy carbohydrates. While many agree that refined carbohydrates play a significant role in obesity and being overweight, some medical professionals feel that the amount of alpha amylase produced exceeds the capacity carb blockers have to function properly. Additionally, starch blockers play no role in eliminating the amount of calories from fat that the body consumes. However, patients with Type 2 Diabetes have found success using these supplements to control blood sugar. One huge factor is the difference between prescription blockers (Precose & Glyset) and non-prescription supplements. Supplements may have unlisted ingredients, like stimulants, which can be dangerous to users, while prescription based blockers are regulated by the FDA and will typically not have these other ingredients. In conclusion, it’s best to check with your primary care provider and decide which is best for your current needs.
